#rockbox log for 2005-03-04

00:00:03kergothi loooove the h320 i just bought. so nifty
00:00:05preglowthere are other factors involved
00:00:10DMJCihp-340s cost $690.00
00:00:16DMJCi've seen them in stores
00:00:32DMJCthere are different tax rates between countries
00:00:33preglowi'll have to give around 700$ for a h340 here
00:00:41ScheeI can't find anything else than H320 or H340 here... (for ~400 and ~500 EUR)
00:00:50preglowh1x0 has been discontinued
00:00:52preglowhard to find
00:01:04preglowa pity
00:01:25DMJCif I had the money I'd buy the design for the h1X0
00:01:40preglowit's a great player
00:01:42DMJCimho it's a better starting point for an mp3 player than the h3x0
00:01:45preglowthey could have made a wiser choice of cpu
00:01:55DMJChow so?
00:02:08preglowi hear the arms are great
00:02:32preglowhad a look at arm assembly, looks pretty damn powerful
00:02:48DMJCwhat do the pmps use?
00:02:54preglowno idea
00:02:56kergotharms are indeed great
00:03:27kergoth"arm assembly reads like poetry ;)" −−erikm
00:03:38preglowhe's got it backwards, PERL reads like poetry
00:03:39 Quit ashridah (Read error: 104 (Connection reset by peer))
00:04:10preglowno assembly is particularily pretty, imho
00:04:13DMJCno... poetry reads like poetry
00:04:15preglowbut arm seemed pretty powerful
00:04:15kergothperl reads like vomit spewed onto a disk
00:04:22DMJCprogram code reads like ugliness
00:04:27kergotharm's multiple register load/store are quite nice
00:04:30Bagder !
00:05:16preglowi like the 'list of possible words'
00:05:30preglowleaves no doubt that there actually went some work into this
00:05:58BagderI did a grep
00:07:52BagderI personally like the download binary option
00:08:00Bagderveeery useful
00:08:43DMJCMan strangled by escalator
00:08:52DMJCnow there's a headline you don't expect
00:10:06preglowbut now i'll have to face the problem of how to commit this code without apologizing loudly every time someone mentions it
00:10:27preglowit really is quite ugly
00:10:50BagderI'll give you permission to blame me
00:11:11preglowthe imdct_l replacement is a HUGE blob of asm

00:25:12preglowthere's alot more plain ordinary 68k asm work to be done in that than the one i did
00:25:21preglowand i guess it'll be faster with data in iram
00:26:49preglowand it'll have a smaller footprint

00:28:40Rickcan the iriver 'joystick' toggle two directions at once? (eg diagonal)
00:28:56Rickwonder how that'll work out with rockboy
00:28:59preglowit wasn't designed for stuff like that
00:29:05preglowwell, you'll quite simply just have to get used to it
00:29:16preglowyou can't even press a button and a direction at once
00:29:22preglowwith the notable exception of the play button
00:29:28DMJCwhy is that?
00:29:43preglowit's designed that way
00:29:49preglowthere isn't one wire per button
00:30:02preglowthere is one wire for all buttons, and an adc that checks which has been pressed
00:30:15preglowit's logical for an mp3 player, but not a handheld gaming device, which the h1x0 was never intended to be
00:30:15Rickno way around it?
00:30:28preglowno, no easy way apart from a really extensive hardware mod
00:30:30Bonkershow about a hardware mod? ;)
00:30:38Rickwhat about the remote plug?
00:30:41Rickis that a standard plug?
00:30:43preglowBonkers: it would have to be a really sofisticated mod
00:30:47*Rick has never seen a plug like that before
00:30:48DMJChmm.... idea
00:30:57DMJCwould it be possible to create a usb hand controller?
00:31:03preglowRick: the remote is connected the same way
00:31:04Bonkerspreglow: the buttons form a voltage divider or what?
00:31:05Rickwell, methinks data can travel both ways for the remote thing
00:31:09preglowBonkers: exactly
00:31:09DMJCthat plugs into the port on the bottom...
00:31:10Rickso I dunno
00:31:15ashridahDMJC: there's no access to the usb port
00:31:16DMJCthat'd be cool
00:31:21RickDMJC: from what I understand, it's slave
00:31:23Bonkerspreglow: so wouldn't two buttons also have a unique voltage?
00:31:27DMJCI thought it had usb host
00:31:33Rickdunno then
00:31:35ashridahDMJC: since the usb port connects directly into the usb-hdd bridge
00:31:37preglowRick: if you made a button controller that transmitted via spi, you'd have a thing that could work
00:31:39Bagderthe 3x0 has usb host
00:31:44ashridahDMJC: the 3xx can act as a host
00:31:46Bagderthe 1x0 does not
00:31:58Rickis that remote control plug a standard thing?
00:32:07preglowi have no idea, why does it matter?
00:32:10DMJCiirc h1x did have usb host
00:32:15DMJCbut it's disabled
00:32:16preglowyou'll still have the same limitations
00:32:18BagderRick: I very much doubt that
00:32:23DMJCthe hardware actually supports it
00:32:26DMJCask linus
00:32:38RickBagder: that's why i'm asking :)
00:32:38RickI've never seen a plug like that
00:32:42DMJCI remember ppl talking about that
00:32:46preglowRick: it's not so much the connector standard, it's how the cpu is wired to the connector
00:32:52preglowRick: you can't change that easily
00:33:07*Rick isn't much of a hardware guy :(
00:33:38DMJCok, so how would we go about making an spi remote?
00:33:43RickI was just thinking about that today because I havn't been able to use my remote (it's "broken")
00:34:10Rickhoping the iriver site still offers them
00:34:36preglowDMJC: well, a set of buttons and an spi interface
00:34:45Rickspi = ?
00:34:49preglowDMJC: for all i know, the spi might be unidirectional and might not work
00:34:56preglowRick: just a way of transmitting serial data
00:35:01DMJCwhat if you have an old nes remote hehehe
00:35:10Rickspi to me is a plugin system for susie (image viewer :p)
00:35:16DMJCI mean controller damnit
00:35:20Bonkerspreglow: say there's 5 buttons, that's only 2^5 = 32 combinations, why can't an ADC reconginze 32 different voltages? or is it like a 3-bit ADC?
00:35:21Camilospi is like a bus, you can have masters and slaves on it
00:35:33preglowBonkers: it's not like that, the button that you press override all the others
00:35:45preglowBonkers: combinations are out of the question from an elecrical point of view
00:36:17Bonkerspreglow: it's not 1 resistor per button and then a common resistor for the other half of the divider? I figured the button resistors would just be in parallel when multiple ones are pressed
00:36:41Rickpreglow: does the remote also override any buttons pressed on the main device?
00:36:50preglowBonkers: if you press a button, the button acts as a short circuit through to a resistor
00:36:54preglowBonkers: i THINK
00:37:26preglowBonkers: in any way, i'm pretty sure it won't work, there are schematics available, so feel free to investigate
00:37:30preglowRick: no
00:37:30Bonkerspreglow: so it's like 5V−−−−-/\/\/\−−−−-button−−−−-GND
00:37:47Rickpreglow: hmm. :p
00:38:02Bonkerserr, 5V−−−−/\/\/\−−−−button−−−−−−**−−−−-\/\/\/\−−-GND and the ** is where all the other buttons connect too
00:38:12DMJCit's wired in series
00:38:17preglowRick: haha, well, you try, one finger on the directional stick, one on the play button of the unit, and the last non-existing hand on the remote
00:38:18DMJCnot gonna work
00:38:21DMJCnuff saif
00:38:30Bonkerspreglow: what device is this exactly? or do you have a URL for the schematic
00:38:30Rickpreglow: that's the problem
00:38:32Rickmy remote is broken
00:38:34Rickso I can't test
00:38:37BonkersDMJC: I'm just curious, it's not like I actually have one of these things
00:38:38preglowBonkers: it's on
00:39:13 Part Bluechip
00:39:28amiconnpreglow: I think multi-button would work in principle. The archos button hookup is similar, different resistors per button and a common resistor connected to ground.
00:40:05amiconnThe problem is that the levels are rather close together, and the tolerances between 2 units might be larger than the difference between 2 levels
00:40:08preglowamiconn: depends on resistor choice and adc resolution, really
00:40:20preglowand adc is probably eight bit
00:40:21amiconnADC is 10 bit on archos
00:40:40amiconn(it's the SH1 integrated adc)
00:40:56preglow10 bit adcs seem to be pretty common on microcontrollers
00:41:08RickWish I knew more about hardware :)
00:41:23preglowRick: read up, it's not that hard
00:41:34amiconnOn the recorders there is another problem though. Any combination that includes the button with the "strongest" resistor leads to an adc overflow :(
00:41:46Camiloit's still a weird design for a remote
00:41:52preglowCamilo: why?
00:42:21amiconnIt saves wires, and that's the point here
00:42:27preglowwell, yes, but you have to do it like that to not have to use a parallel design
00:42:58preglowit's a perfectly sensible design
00:43:06CamiloI suppose if you already have a DAC spare and you want to build the cheapest possible remote...
00:43:27ashridahsaving space on a pcb saves you more than the engineering effort involved in designing a multiplexed system
00:43:58amiconnHowever, I wonder why archos didn't use a proper R-2R network.
00:44:07preglowamiconn: laziness
00:44:21Camilocheapest components?
00:44:39Bonkersamiconn: isn't R-2R going to use n-1 more resistors were n is number of buttons?
00:44:51preglowamiconn: if i'm not completely mistaken, there's more than one thing "odd" about the archos hardware ;)
00:45:00Bonkersor maybe n-2 more
00:45:43amiconnI presume there are integrated resistor arrays for R-2R networks
00:45:54preglowyes, there are, i think
00:46:32amiconnpreglow: Yes. That seems to be a common sense across mp3 player manufacturers though (the hardware oddness I mean)
00:46:48preglowat least iriver endian swapped the ide interface
00:47:36amiconnThinking about iriver... Choosing a CPU capable of running at 140 MHz in principle, but not stable due to thermal problems
00:47:58preglowthey probably never intended to have it running at 140 in the first place
00:48:01preglowbut who knows
00:48:09elinenbeamiconn: what speed does iriver run the chip at?
00:48:19preglowelinenbe: i've heard 96 mhz max
00:48:27amiconnI'd really like to know how Motorola manages the mp3 decoding in realtime with just 20 MHz
00:48:44DMJCwrite to the metal
00:48:48preglowamiconn: well, the source is available if you contant them :)
00:49:06preglowi guess iram is a major component
00:49:11preglowand l337-ass optimizing
00:50:01preglowtheir programmers are probably hung like bulls
00:50:21preglowi dreamt about vim the night after i did the imdct_l asm opt
00:50:25Rickhave any problems come up with the bootloader?
00:50:33preglowRick: none
00:50:41XShocKby the way, did anyone check the demo MP3 decoder on motorolla site?
00:50:54preglowXShocK: it's binary only, isn't it?
00:50:58XShocKno. source
00:51:06RickWanted to try doing some dev but reluctant because I like my H120 :P
00:51:15XShocKi will check now and say for sure
00:51:18Camiloyou have to sign up to get it though
00:51:20BagderRick: now don't be a chicken ;-)
00:51:32preglowi was the second person apart from linus to flash mine
00:51:45preglowcan't remember who the first was
00:51:53RickI've never done any dev outside of a PC
00:52:04Rickwell, aside from TI assembly. ;P
00:52:08Bagderpreglow: I could've been me, but i don't know
00:52:09preglowRick: i've mostly done pc work as well, with the exception of microcontroller stuff
00:52:20preglowBagder: don't think so, some guy just jumped in and flashed it
00:52:26Rickcan plugins cause an unrecoverable crash?
00:52:41Rickor will the RESET button take care of that just fine?
00:52:42preglowRick: everything can, if it writes the flash
00:52:51preglowRick: odds are very small of that happenin, though
00:53:00preglowRick: and yes, reset has handles everything i've ever run across
00:53:06Rickthat's very good news
00:53:13Bagdereverything anyone has come across actually
00:53:26Bagderexcept for the guy whose reset button was broken
00:53:34RickI guess I should test that
00:53:43Rickbefore I try ;)
00:54:20XShocKpreglow: it is really BINs only, libsrc.a library... :(((
00:54:32XShocKand header file for it
00:55:28preglowXShocK: yes, i thought so
00:56:26Rickjust curious, does the iriver firmware keep its settings in flash?
00:57:06preglowRick: eeprom
00:57:26preglowRick: keeping things in flash isn't very wise, it can't take more than a couple of thousand write cycles, at worst
00:58:11 Quit webguest43 ("CGI:IRC")
00:59:16preglowlooks like DMJC was the first to flash it
00:59:53preglowDMJC: madman
00:59:53DMJCnow they tell me
01:01:09DMJCit worked beautifully
01:01:17DMJChaven't flashed it since
01:01:29amiconnBagder: rockboy.ovl ends up in .rockbox/rocks, not in .rockbox/viewers where it should be....
01:01:40preglowi've flashed it a couple since
01:02:03preglownothing more nerve wracking than the first time, when it just blinked its hdd light for about five minutes or so
01:02:23preglowi was more or less preparing to package the thing in and ship it off for sweden, heh
01:02:45DMJCI'd have had to give it to a mate of mine to work on
01:02:49DMJChe's a hardware junkie
01:03:42DMJCit's funny actually... if he saved his cash instead of buying all the crappy players he has... he'd be halfway to an iriver

01:06:00DMJCfile cut/paste would be kinda cool
01:06:08preglowwhy? :P
01:06:31DMJCso after you've leached music from a friend you can spend the bus trip home organising it
01:06:41preglowwill be doable, for sure
01:06:41RickDMJC: the latest firmware added deleting iirc
01:06:45preglowbut i think i'd wait
01:06:57preglowRick: rockbox can rename as well!
01:07:01RickI was thinking of making a text editor actually
01:07:08Rickan efficient vkeyboard or something
01:07:13preglowthere is on already
01:07:16DMJCso I can edit my phonebook..
01:07:20preglowtry renaming a file
01:07:32RickDon't have rockbox on my iriver yet
01:07:43Ricki'm building a gentoo vmware install so I can have access to buildtools :p
01:08:07preglowthere are limits to how efficient the keyboard can be
01:08:09preglowbut it works
01:08:30RickI was thinking about how to do a vkeyboard
01:08:45RickI was thinking different keyboard modes, lowercase/uppercase/macro (user definable)
01:09:20DeadManvkeyboard is pretty easy with joystick
01:09:32DeadManscroll to letter click
01:09:36*Rick nods
01:09:47DeadManhold rec key for shift click

01:11:28DeadManor just use rec key for click on for cap...alsorts of ways
01:11:40preglowyou can hold play and press other things
01:11:53preglowbut that's the only exception
01:12:14DeadMananyhow nothing amazing gapless working yet on iRiver?
01:12:24preglowwe have no codec api yet, so no
01:12:40RickI was actually thinking of using a/b key for modes
01:12:51*Rick shrugs
01:12:56DeadManoh so that libmad at 104% ain't worth anything unless it has some place to output to?
01:13:13preglowwhich reminds me i should have commited libmad code
01:13:21Rickpreglow: are there any plans on "cleaning up" the plugin api?
01:13:25preglowbut i should have done that before i had two beers and grew tired
01:13:30preglowRick: in what way?
01:13:50Rickrenaming things to better suit the fact that multiple players are supported
01:14:00Rickmp3_* -> audio_* or something :P
01:14:11preglowahh, like that
01:14:16preglowthat's got nothing to do with plugings
01:14:20preglowand we'll get around to that
01:14:23Bagderfeels pretty secondary to me
01:14:28Rickyeah, just curious
01:14:31preglowit's just semantic
01:14:34*Rick nods
01:15:03*Rick watches his gentoo stage tarball extract
01:15:20preglowwhat we really need is people working actively on the codec api
01:15:23XShocKso the current problem is only in the architecture of the sound framework, since all parts: decoding and playing are done.
01:15:33preglowand perhaps another person on codecs optmisations
01:16:38preglowbut it doesn't matter, it's just been one month since the first person flashed his player, we've really gotten quite far
01:17:01RickI had been checking routinely for updates and figured I should check it out in more depth
01:18:08preglowi've just been involved for little under a month myself
01:18:16DeadManyeah lot of progress...makes me optimistic it will be nearly there in the next month ;)
01:18:44RickDeadMan: nah... not that quick ;P
01:19:12DeadMandepends on what's happening and who works on what
01:19:13XShocKi am sure that all features of a normal player will be done in next month. :)
01:19:39RickI thought it was a matter of simply 'fixing' the features and retaining the features that rockbox already has?
01:19:49Rick(and then, implementing features afterwards)
01:20:01Ricknew features that is
01:20:04preglowRick: there's more to it, h1x0 series brings along a lot of possibilites rockbox never had before, like software codecs
01:20:18RickI just thought there would be more focus on getting what is already there to work first
01:20:20preglowand that alone is a very big part
01:20:25preglowwell, it does
01:20:32preglowrockbox does work
01:20:45preglowthe only things it lacks are stuff that was handled by hardware before
01:21:17DeadManmore software coding involved on the codec end
01:21:30BagderRick: you really should install rockbox and try it out
01:22:13preglowRick: hell, if it does nothing but bore you to death, you can still show your friends how cool you are by loading super mario land on your mp3 player!
01:22:20amiconnBagder: Got my remark concerning rockboy.ovl ?
01:22:26DeadManI'm not installing it until I can get MP3 playback with gapless. it's the only reason for otf playlist I guess but that's about it
01:22:33Bagderamiconn: I did, fixing it tomorrow
01:22:34Rickwhat is gapless?
01:22:35 Quit matsl (Remote closed the connection)
01:22:40preglowRick: no gaps between songs
01:22:40amiconnBagder: Okay.
01:22:46Rickdoesn't the latest firmware have that?
01:22:50XShocKRick: do it.. you will not regret it at least. :)
01:22:51preglowRick: no
01:22:54preglowRick: it never will
01:22:56Rickwhat's the option for?
01:23:08preglowRick: god knows, it doesn't do what it should
01:23:13DeadManseamless playback of DJ mixes and live recordings
01:23:25RickI hadn't tried it yet
01:23:26preglowyes, and electonic music in general
01:23:30RickI guess it's like that language menu
01:23:33preglowmore than half of the cd's i own have no gaps between songs
01:23:43Rickyeah i've noticed that myself
01:23:52Rickthat's one feature I wished winamp had
01:23:55Rickplaylists in playlists
01:24:11preglowdump winamp, use foobar2000
01:24:24Rickbasically, a playlist in the playalist would play that playlist with no shuffling in order
01:25:17XShocKare there people good at electronics?
01:25:24preglowXShocK: perhaps
01:25:52Rickdefine electronics
01:26:06XShocKi want to add RTC to iriver.
01:26:15preglowreal time clock
01:26:31XShocKthrough the i2c line, for example fm-radio bus line.
01:26:32preglowXShocK: you'd have to find a free interrupt pin
01:26:51preglowor some way of having the rtc switch the cpu on
01:27:20*Rick watches portage extract
01:27:36XShocKfirst i wanted to implement the timing only, no auto-starting on alarm.
01:27:37RickI think I should have picked a lighter flavor of linux for the vmware buildtools :P
01:28:03preglowRick: gentoo is for men
01:28:17XShocKi have a DS1340 chip, it has i2c bus.
01:28:20RickI like gentoo, don't get me wrong
01:28:31Rickjust taking forever to install atm ;)
01:28:42preglowXShocK: well, if i don't remember incorectly, you can just stick things strait onto the i2c bus and have it work
01:28:47 Quit lolo-laptop ("Client exiting")
01:28:54preglowXShocK: provided you've got a driver, of course
01:29:07preglowRick: yes, i know, i had to install xwindows on it today
01:29:23XShocKfrom what i understood i don't need to change any component on the player itself. i only attach the chip through resistor on bus lines.
01:29:28preglowXShocK: yes
01:29:30Rickluckikly i'm just using a stage3 for the vmware install ;P
01:29:31preglowXShocK: that's correct
01:30:17XShocKso, what i am worring about is electrical current while the player is off, but the rtc is working.
01:30:36XShocKshould i cut the rtc from i2c bus when the player is off?
01:31:08preglowit shouldn't try to sense the bus when power is off, no
01:31:28preglowbut i don't know how you should handle that
01:32:26XShocKso, if i let rtc chip be connected to bus while all other chips do not have power, then i will get all sorts of troubles, yes?
01:32:54preglowdoes anyone know if sim buils vomit on seeing something declared belonging to section .idata og .icode?
01:33:15preglowXShocK: you might, i'm not sure
01:33:45Bagderpreglow: I believe it defines the attribute() to nothing for the sims
01:33:53preglowBagder: that was what i was hoping
01:34:13amiconnpreglow: Iirc these sections don't matter for the sim builds. They are included just like normal .text / .data sections
01:34:16preglowi believe linus agreed on having a #define to do the attribute iram stuff, but hasn't been done yet
01:34:41amiconnI believe I've seen this while searching for the cause of the non-working lseek(()

01:35:38XShocKok. i am pretty afraid i need to isolate it, but it will make everything pain in the ass since i will need additional components to put...
01:35:45amiconnIf you're on windows, why don't you use cygwin?
01:36:08preglowXShocK: depends on how the bus is wired
01:36:09Rickbecause cygwin is bizaarely slow at compiling
01:36:29preglowXShocK: ask linus, he should know this
01:36:31amiconnI use it here; can't say that it is excessively slow
01:36:46preglowamiconn: i've never been able to make cygwin work very well
01:36:46Bagderamiconn: compared to a linux build, it is
01:36:47RickI havn't touched cygwin in years
01:36:50Rickso it could be different
01:36:52preglowamiconn: so i've grown to dislike it ;)
01:37:18XShocKyep, i will ask him. he addmitted that i don't need a pull-up resistor, but i forgot to ask him that problem..
01:37:20preglowi've got a linux box anyway, i prefer to use that
01:37:46Rickiriver doesn't have floating point right?
01:37:54preglowRick: correct
01:38:59amiconnBagder: When rebuilding my whole assortment of simulator & target builds, it doesn't take significantly longer than the official build sequence. That's on a laptop btw
01:39:40preglowamiconn: depends on what you're doing. configure is insanely slow on cygwin
01:40:12amiconnThe only slow thing in configure is the language selection - takes a few seconds
01:40:21preglowahh, didn't mean your configure
01:40:24preglowautoconf configure
01:40:51amiconnrockbox doesn't use autoconf, so I can't tell much about that
01:41:03XShocKi think getting clocks and probably alarm on the cost of 4 el. components. will be good. i actually was pretty delighted that DS1340 has such small size(2 by 2 millimeters. :) )
01:41:23preglowi tried to use cygwin to build csound, failed completely in making it work, ended up installing linux on this box as well

06:54:59Rickbut it said it was an alternate
06:55:22ashridahyeah, it isn't really.
06:59:18ashridahthe problem is, it probably still is for the SH platform archos uses
07:00:12Rickfirst it lists (what I assumed were the 'default')
07:00:20Rickthen under Coldfire it says the cvs binutils is optional/alternate

07:53:14LinusNwould have been better to export the core menu code to the plugin api
07:53:14pabsLinusN: where's the other one?
07:53:29pabsLinusN: i looked for a menu api and didn't see one handy
07:53:38pabs(in the plugin api documentation, etc)
07:53:42pabsso i wrote that one
07:53:51LinusNin fact, i like it
07:54:11LinusNit has a few drawbacks though
07:54:27pabsprobably, i just whipped it up
07:54:28Rickoh that's evil
07:54:28LinusNone obvious is that it can't handle long strings
07:54:31ashridahthe one in rockbox? it does look decent. a smaller font might be good, plus a scrollbar...
07:54:32*Rick heads to recompile is kernel
07:54:46pabsLinusN: nope, and it won't handle huge fonts gracefully either
07:54:51pabsLinusN: that's easy enough to fix though
07:55:18pabsLinusN: like i said, i ddin't see a menu api, so i tossed that one together
07:55:22pabsLinusN: i'm still refining it
07:55:39pabsLinusN: mainly i was mad because rockboy was quitting on me, and i wanted to be able to save tsate
07:55:45pabsLinusN: (which the second patch adds)
07:59:32Rickthere, kernel rebuilt with vfat support :)
08:01:00pabsLinusN: i can either crop the strings to fit them in the menu, or add a thread that scrolls them (since i kind of like having the game showing a bit in the background, it gives a nice modal feel to the menu)
08:01:32LinusNpabs: the rockbox lcd driver already supports scrolling
08:01:37pabsLinusN: if you're going to expose the menu stuffto the plugin api it'd be nice to have a standard open and save file call too
08:02:15LinusNpabs: "a standard open and save file call"?
08:02:38pabsyeah, somtehing that brings up a menu that allows users to scroll around and select a file
08:02:58LinusNa file requester?
08:03:07LinusNwe don't have one
08:03:19LinusNfeel free to write one
08:04:36pabsLinusN: i know the lcd driver supports scrolling, but i didn't think it'd support scrolling for part of the screen (like, a chunk of text that wasn't full screen)
08:05:07Rickpabs: sorta like buffer areas within the main lcd?
08:05:16LinusNthat's true, it needs support for cutting off the right part
08:07:11pabsRick: yeah
08:07:23pabsthat's what i'd want to do text scrolling in teh rockboy menu i did
08:07:42pabsmaybe i'm just picky :o
08:07:45Rickoh great, forgot to unzip
08:07:51*Rick feels silly
08:09:04Rickwhat's the modified firmware do?
08:09:16RickI mean, other than load up rockbox
08:09:41pabsRick: well, it makes you popular with the ladies!
08:10:23Rickjust curious because I got a nice blank screen for ~5 seconds before it did anything
08:12:46Rickother than that it seems i'm all good to go
08:14:22LinusNit doesn't do anything else but load rockbox, but the FAT driver might recalculate the free space the first time you boot
08:15:04LinusNand it might take a few disk operations to find out that the rockbox files are missing before it boots the original firmware
08:15:14Rickah, okay

09:45:59pabsLinusN: oh that's from the rockboy defines

09:46:18Rickghode|afk: how would that work without color support?

09:46:34ghode|afkdid not mean it like that ;p
09:46:43pabsLinusN: hence the lack of api calls
09:46:54ghode|afkyou can play gbc roms atm, but you can't open them from the dir view, only .gb roms

09:48:16Bagder.gbc? they're named .cgb in the viewers.config file
09:48:38ghode|afkhmm all the gbc roms i've vound have had the ext .gbc
09:48:39pabsBagder: all teh ones i've ever seen are .gbc i think
09:48:42BagderI fixed the problem with multiple extensions for a single plugin yday
09:49:01Bagderthen "someone" should fix the viewers.config
09:49:39Bagderthe problem was only in how the viewers.config is made when make zip is used

09:59:03LinusNmay not be necessary
09:59:46LinusNignore me
10:00:22pabsobviously that's only in lcd-h100.c and lcd-recorder.c, so it's not too bad
10:00:40LinusNpabs: while we're at it, why not move the common code to a new file, lcd-common.c
10:00:48Bagderwe should unite more things between lcd-h100 and lcd-recorder
10:00:56Bagderpossibly in a new lcd-bitmap.c

10:01:50pabsLinusN: is that roughly what you're looking for though?
10:02:08vrmit's possible to remote control the rockbox using USB, for example start playing a song ?
10:02:36LinusNi'm not sure if i want left/right/top/bottom or x/y/width/height
10:02:53LinusNvrm: no
10:03:01Bagderthe new build script seems to work
10:03:21pabsLinusN: seems like margins are usually relative to their respective edge
10:03:25pabsLinusN: but it's all the same to me
10:03:40pabsi was just going on how people seem to do them normally
10:03:56pabsi guess i'd call it a clipping region if it's x/y/w/h, and a margin if it's relative ot the edge
10:04:01pabsthat's just semantics though :D
10:04:08LinusNyes, l/r/t/b is appropriate for a setmargins function, but maybe it would be better with a setwindow() function, i don't really know
10:04:49pabsLinusN: if you prefer w/h that's doable

10:19:54Bagderactually I bet it is a true bug
10:20:03Bagderthat my fix reveals
10:20:34Bagdersince viewers.config never contained more than one plugin <=> extension before
10:20:48Bagderand now a single plugin suddenly is listed for multiple extensions
10:21:35Bagderat least I can't see any problem with my generated viewers.config
10:24:37LinusNviewers.config was never designed to contain more than one entry per plugin, iirc
10:24:45ghode|afkBagder: the cgb ext should be "gbc" not "cgb"
10:26:15BagderLinusN: did we really limit it to that?
10:26:28Bagderseems very restrictive
10:26:35 Part vrm ("Leaving")
10:27:30Bagderand it would even more explain the problem :-)
10:27:37LinusNmaybe i am wrong, but iirc, the code has that limit
10:27:53LinusNthough it shouldn't, imho
10:27:59BagderI agree

10:28:13Bagderthe buildzip flaw has hidden this limitation all this time

10:36:16LinusNon the actual target?
10:36:39markunWhere are the rockbox settings stored on the iriver?
10:37:10LinusNin an unused sector after the partition table
10:37:25markunhow strange then that they got wiped..
10:37:25DeadManoh so it loads it at boot time?
10:37:30pregloware we planning to use the eeprom for anything?
10:37:39LinusNnot sure
10:37:52DeadManand after a format it still retains those settings?

10:38:44DeadManmust be something to tell even when you are formatting via usb not to go near that portion of the disk
10:39:10BagderDeadMan: as long as you have a partition, you won't risk that
10:39:17DeadManI'd hate to see a bad sector appear there
10:39:19Bagderand even if you did, it is only your settings
10:39:27DeadManthat would annoy

10:39:36Bagderexpect to be annoyed
10:39:42Bagderwe frequently change format of it
10:40:20DeadManI would have thought they would hold settings in memory for as long as the battery was charged
10:40:23Bagderkeeping up with devel means blowing your settings every once in a while
10:40:45BagderDeadMan: they? rockbox surely does
10:41:01DeadManI would have thought so
10:41:07LinusNBagder: no we don't
10:41:17Bagderyes we do

10:43:56Bagderwe already have that
10:44:00DeadManoh ok
10:44:02Bagderthey're called config files
10:44:09DeadManI've not tried Rockbox yet
10:44:24DeadManI don't see any point for me until I get MP3 playback ;)
10:44:32Rickwhy don't you use a file already?
10:45:38LinusNhistorical reasons
10:45:45DeadManwill the gapless portion of the code have to be rewritten for the iRiver?
10:46:07LinusNnot for pure mp3 gapless playback
10:46:43DeadManso how will audio be loaded into memory?
10:47:01DeadManiRiver's firmware buffers the entire memory up
10:47:17BagderDeadMan: that's the only way to do it
10:47:46Bagderneed to keep the disk spinning as little as possible
10:47:47DeadManthat's how it saves on power too I guess
10:48:21DeadManso for gapless it would need to buffer in the next song as well or at least the first portion?
10:49:16DeadManI mean. If the buffer is already full...
10:49:41Bagderthis is nothing new for us
10:49:48Bagderrockbox already plays on Archos, you know
10:49:52DeadManjust curious :)
10:50:03Bagderif the buffer is full, there's no need to load more data
10:50:22Bagderthen you play music until there's a need to load more data again
10:50:45DeadManyeah ic
10:51:09DeadManI forget playback and read into memory are seperate events. linear thinking me ;)
10:51:43preglowthe iriver firmware doesn't even buffer a song if it can't fit it in the buffer
10:51:52preglowthat's plain stupid, if you ask me
10:52:05DeadManso if the song is bigger than 32mb it does what?

10:55:31preglowDeadMan: it handles a single song bigger than the buffer
10:56:32LinusNpreglow: so how's the libmad opts going?
10:56:33DeadManI know. Just wondering what you meant by doesn't even buffer if the song can't fit in the buffer

11:09:03amiconnBagder et al: The "file type string buffer empty" isn't really a bug, it's just a bit misleading message. It should rather say "filetype string buffer full"
11:09:33amiconnThis is because of the supported file types increased so much that the buffer storing all the plugin names and icons is too small
11:10:14amiconnapps/filetypes.c line 49: #define STRING_BUFFER_SIZE 256
11:10:53preglowLinusN: should i let all .idata attributes be in there as well?

12:35:06ripnetukhcl - could we maybe rotate the screen 90 degrees, then you lose left and right margin, not top or bottom? or is the aspect ratio on the iriver not what it looks like?
12:35:52ripnetukmight make mario and tetris playable
12:35:57HClthen you'd have too many vertical lines
12:36:17ripnetukyeah, its a compromise

12:40:02DeadManThe remote LCD could be interesting
12:40:11DeadManfitting in info
12:40:13ripnetukDeadMAn - until we have a proper driver for it, I reckon we should at least scroll the rockbox logo across it :)
12:40:32DeadManas long as I can see what I am ding :)
12:40:33ripnetukhcl - does grayrockbox need you to manually boost the cpu?
12:40:46HClit automatically boosts to 120mhz
12:40:56HClyea, linus increased it
12:41:06Lynx_awyis the temperature issue solved?
12:41:07ripnetukwoah! i missed that... what happened?
12:41:18HClhe didn't seem to have any trouble at 120mhz
12:41:20BagderLynx_awy: no
12:41:31ripnetukhow did he solve the crashing, presumed overheating?
12:41:39DeadManmight be worth making sure apps only use that as a max
12:41:50HClwell, that happens at 140mhz, not 120mhz, as far as i know
12:41:52Bagderripnetuk: he didn't, that was at 140
12:42:17ripnetukoh yeah <−−−− me->memory != good
12:42:17DeadManI think iRiver use 96 as a cautious measure and to cut down on battery use?

12:42:38ripnetukim guessing iriver use the lowest they can with their mp3 decoder still working

12:42:53HCli'm not sure what to think of 120mhz either, i'm still gonna work on dynarec to cut it down more.

12:44:05*HCl hears his belly rumble, goes to search for food
12:44:32DeadManmore realtime that is. what do you think you could ramp it up to?
12:44:36ripnetukHCl - you kudos ! that is fantastic
12:45:09HClhehe :p
12:45:12HClkudos? :P
12:46:04DeadManif iRiver DID use 96Mhz for MP3 playback as the minimum they could clock the cpu down to maybe that is what to aim for with libmad optimization?
12:46:33DeadManI dunno I'm just guessing :)
12:46:58Lynx_could libmad ever be optimized as good as a decoder written specifically for the processor?
12:47:14DeadManPreglow may know
12:47:15Bagder"ever" ? sure
12:47:25Bagdergiven infinite time and effort, everything is
12:47:26stripwaxDeadman - I'd agree, although tremor's likely to use more CPU right? if ogg decode runs realtime at 96Mhz for iriver, libmad should be faster
12:47:39Lynx_Bagder: if it's rewritten 90%? ;)
12:47:42DeadManthat is true
12:47:45stripwaxunless iRiver ramps CPU up for ogg decoding (? would explain shorter battery life)
12:48:04DeadManwould need to decompile the iRiver firmware to know ;)
12:48:25HCli think that eventually we'll wind up either rewriting 90% or looking at iriver firmware's codecs
12:48:27Bagderwhy bother about how they do it?
12:48:38HCleither way, i'm happy that i can at least play gameboy games now :P
12:49:02DeadManit's always handy to look at how others do it for pointers on beating it ;)
12:49:26BagderHCl: there's also the option of using a decoder with less quality and format-support ambitions than libmad
12:49:36DeadManPlaying games is the least concern to me but hey...
12:50:06BagderI think libmad's high ambition in playing with high quality is what gives us performance problems
12:50:11DeadManMP1 and 2 is not really needed
12:50:29DeadManI don't know many people who use such formats
12:51:34DeadManMP2 is only used for PCM MPEG1/2 movies
12:51:47DeadManNo idea what MP1 is used for
12:51:48stripwaxbagder - it should be possible to tune libmad to trade off quality vs performance (in fact LinusN was suggesting exactly that, but only in reference to one small part of libmad).
12:51:49Bagderand some sat radio stuff too I believe
12:52:00LinusNfrom what i have heard, iriver runs at 72MHz for mp3 and 96Mhz for ogg
12:52:21Bagderstripwax: of course it is possible, the question is just how much work it requires
12:52:34Bagderand how much libmad that is left when done ;-)
12:52:44DeadManI say get the API in place forst and optimize the decoder after that
12:52:57Bagdernooooo, let's have more games first! ;-P
12:53:10stripwaxBagder - I'd agree with DeadMan
12:53:12ripnetuki thought that mp3 was very specific about decoding (ie, the decoding is deterministic), but slack in the encoding (ie, the encoders can work how they like). How therefore can you sacrifice quality for speed? is it in the post-processing filtering?
12:53:15stripwaxLinusN - ah, thanks!
12:53:23DMJChow much sound stuff works?
12:53:49ripnetuki like the menus on rockboy
12:54:07stripwaxripnetuk - if you decode an mp3 using internally 16-bit data, the output will not be as good as if you use internally 32-bit data (for example). So it's the precision on the math within the mp3 decoder
12:54:08LinusNDMJC: nothing (in cvs)
12:54:20*DMJC cries
12:54:29DeadManto get the tradeoff in quality vs. decoding right would you not need to analyze the waveform on output?
12:54:48LinusNyou can derive it mathematically
12:54:57stripwaxripnetuk - there's *also* post processing filtering, I'm not sure what libmad does there (e.g. we could turn off dithering if it's built in)
12:54:57ripnetuki see
12:55:15LinusNbut you'd have to listen to observe the effects of course
12:55:26DeadManI can never hear the diff between 16bit,24bit and 32bit anyhow ;)
12:56:01stripwaxDeadMan - I'm not talking about the final result, just the precision of all of the calculations used to *get* to the final result
12:56:08preglowyou can simplify things quite a bit before resolution drops under 16 bits
12:57:53*HCl sighs.
12:58:09*DeadMan size
12:58:09ripnetukmy reference was (the bit under DEciding of MP3 audio)... i guess we are not going to be 'bitstream compliant' !

13:00:58ripnetukdid it? i never got very far on that... never played the ff games
13:01:12preglowi've played all of them :P
13:01:15pregloweven the nes ones
13:01:23stripwaxAny, back on topic, I thought 'bitstream compliance' was all about whether *any* decoder could decode the output of *any* encoder; and not that the decoded output would always be identical
13:01:26ripnetuki bought one for the psx, but never got very far
13:01:34preglowstripwax: correct
13:01:46preglowstripwax: but there are also compliance tests, your output has to be reasonably similar
13:02:01ripnetukso wikipedia is wrong? we ought to correct it

14:27:09ripnetukin fact, is it even worth loading that much in at once? i usually only listen to the thing for 30 mins at a time... there must be a point where its not economical to load in 30megs just in case... also, I very rearely listen through, i am forever swapping tracks
14:27:38preglownot only doesn't it do that, it uses coldfire incompatible assembly
14:27:41Bagderripnetuk: yes, it might be worth doing some statistics to figure that out
14:27:53ripnetukaltough ususally i press next on shuffle, so chances are the track I want is somewhere in the 30 megs
14:28:12preglowit should preload shuffled tracks as well
14:28:21LinusNripnetuk: it will *always* be next
14:28:24ripnetukpreglow - im assuming it will

14:36:10LinusN32k seems reasonable

14:51:28preglowso, any takers?
14:52:01*LinusN is swamped with work
14:52:06ripnetukcant we write a simple profile tool? i wrote one in delphi for work, and it basically keeps a tree of function references, and you have to manually call startprofile and endprofile. It keeps track of the number of times it was called, and the total time in that function. The tree lets you know where the function was called from. Ive also written a graphical displayer for this data. This has helped loads in making our product fas
14:52:27ripnetukthe current 'leaf' of the tree is stored in a lifo stack
14:53:12preglowif you can think of a simple way to make it work in our case and are willing to do some work: go ahead :D
14:53:38ripnetuki might just have a go over the weekend
14:53:55stripwaxso each function would have to log its usage at the entry point and at all exit points? that doesn't sound ideal unless it could be automatic! Also is there a danger that it could significantly slow down any (small, very frequently used) functions?
14:54:06preglowmpegdec doesn't even bloody have compatible makefiles
14:54:15ripnetukyes, its a case of you cannot observe without changing what you observed
14:54:55preglowi know of another way, but will probably require disk writing from an interrupt
14:55:06preglowdon't know if that's possible
14:55:27ripnetukthe main problem is you have to manually make the start/end profile calls... very easy in Delphi with try.. finalyl blocks, but in pure c, every exit path has to be considered and a endprofiel put in
14:56:22ripnetukbut... at the end of the day it works, ive got massive speed savings with it
14:56:39stripwaxpreglow/linus - how fast can the cpu run when using the bdm interface?

14:57:15ripnetukcan the gnu tools profiel automatically then? with gdb?
14:57:22stripwaxapparently gdb cannot
14:57:31preglowyou need gprof

14:58:00HClno, heh.
14:58:27preglowbut someone code my idea, please. make a hi res timer that has the interrupt handler check it's own stack frame to see what code was executing when it was called, and log that somehow, then preprocess the data by using the map files to see what functions were used the most

14:59:02preglowit doesn't require any mods to current code
14:59:08stripwaxpostprocess you mean? or do you want the interrupt handler to actually do the map file lookup??
14:59:16preglowstripwax: yes, postprocess
14:59:33stripwaxcould we log over serial somehow?
15:00:05preglowstripwax: i have no idea, if interrupt handlers can write to disk without crashing everything, you can just accumulate some data and write it from time to time
15:01:03stripwaxi guess you could have a plugin that writes a buffer to disk - and an interrupt handler which fills that buffer?
15:01:18preglowbetter to just have the interrupt do it
15:02:18 Quit shatting (" Want to be different? HydraIRC -> <-")
15:02:30preglowif you have to load a plugin, you can't profile anything anyway
15:02:38preglowapart from the disk writing plugin, heh
15:03:05preglowand if the interrupt itself does the writing, you'll have no problems with the disk accesses being profiled as well
15:03:22preglowbut i don't know if this is feasible
15:03:43Bagderor, you disable that interrupt while saving

15:07:38stripwaxpreglow - mm, good point, i guess you only need to profile decoding in memory, not including loading from disk too
15:07:59preglowstripwax: that's most realistic as well, you'll allways do decode to memory when playing music ordinarily
15:08:02stripwaxi.e. loading the compressed audio, *then* begin profiling

15:28:33HClthe first bit drops the calculation of scanlines that aren't needed for that particular mode
15:29:03LinusNR_LY is the scanline?
15:29:05HClscanline_ind is the position where the current scanline should go in the scanline buffer
15:29:13HClfrom 0-143
15:29:54LinusNso you want to add code that translates the scanline number
15:30:20HClnot only that, you need to make sure the scanline doesn't get into the buffer

15:41:58Patr3ck_exactly the same as the tick_count but with higher resolution
15:42:07LinusNhow high?

16:05:14*LinusN has a logic analyzer
16:05:18DeadManPreglow: it would be nice to have a top notch mp3 decoder working but right now I think just getting something running that is low on resource use is more important. Good luck with mpegdec anyhow :)
16:05:30geoff_oHow do you attach the wiggler to the chip?
16:05:53LinusNsoldering iron, steady hands and a lot of patience
16:05:57preglowDeadMan: well, that's the entire point of using mpegdec, is it not
16:06:09DeadManI like to state the obvious ;)

16:36:01preglowright, i've mostly used local trains
16:36:59ripnetuki think they should concrete over the tracks and make a dedicated cycle route
16:37:02stripwaxpreglow - unlucky. they keep saying they're going to get around to replacing them at some time. and then end up pissing all of their budget into a research project which fails. leaving no new train designs, and no money to buy new trains of the previous design.

20:47:06XavierGrhello I've got another question. Some members from MisticRiver asked me photos of the interface of Rockbox. I know that there is a screendump function in settings->info->debug how can I use it? Thanks
20:47:34BagderXavierGr: enable it, then insert the USB cable to make the dumps
20:47:48Bagderthey are them stored as BMP pics on the harddrive
20:49:11 Quit elinenbe_ (" HydraIRC -> <- irc client ownage!")
20:50:15XavierGrbut I guess that I will have to press a button to take the screenshot I need right?
20:51:19 Quit livesNbox ()
20:51:21XavierGrwhich button do I need to press while enabled?
20:52:06Bagderno, you insert the USB cable
20:52:26Bagderduring screenshot mode the ordinary usb mode is disabled
20:55:29XavierGrforgive me but I didnt quite got it. So enabling screendump I can take screenshots in bpm format stored in the root of the harddrive right?
20:56:18XavierGrI have done what you say but I can take one screenshot only of the root folder, what if I want to take a screenshot of the settings or plugins?
20:56:40Bagdergo there, insert cable
20:57:03preglowBagder: is it even correct to have the codecs include standard header files? they can't use any of it anyway
20:57:08XavierGrlets see....
20:57:40Bagderpreglow: right, but strictly speaking the codecs will not be using the plugin API in the future, so it might be...
20:58:28preglowwell, they'll be using a plugin api of some sort, so it'll be just the same
20:59:56XavierGrok it worked thanks, though I cant understand why it is not implemented by pressing one button?
21:00:06preglowoh well, i'll just point the entire bunch to xxx2wav
21:00:24BagderXavierGr: because this way it is much less intrusive

21:51:58HClthe annoying bit is.
21:52:05HClits pretty much the same algorhythm i used earlier.
21:52:22XShocKmichiel_: yes
21:53:02amiconnHCl: The button for the lcd modes on archos should be the on that is not yet used - BUTTON_ON

21:53:45XShocKit is not on cvs yet thou..
21:53:55michiel_any idea how much work it is going to be to play mp3's once libmad is > 100%
21:54:16XShocKneed to develop the sound framework.
21:54:37XShocKthat is it.. libmad is actually higher than 100% now
21:54:47michiel_probably quite a bit of work, yes?
21:54:57XShocKat 120mhz it is if i not mistaken 104%

21:58:12TangChamois told me there were wonderfull progress in mp3 decoding and ome others
21:58:44michiel_progress has been amazing last few days, thanks guys!
21:58:53TangJust installed Rbx on my iHP
21:59:05Tangvery nice :)
21:59:07michiel_my iHP 120 has become my favorite toy again
21:59:16DMJCdidn't someone get flac decoding at 170% of realtime?
21:59:51Stryke`hope musepack is next for optimization
22:00:00michiel_oh well, I've got the simulator working
22:00:10Bagderdon't hope, join in and make it happen!

22:01:52Bagderrasher: you mean in the menu?
22:02:08rasherBagder: yup
22:02:13TangI don't know if it make sense
22:02:15Bagderits a bug
22:02:30Tangbut seems the iHP freeze
22:02:34Bagderpreviously there was a bug that made reach plugin only appear once in the viewers.config file
22:02:42DeadManWill 120Mhz eat more battery?
22:02:51Bagdernow they can appear more than once, for each extension they "own"
22:02:52Tangwith rbx 20050303 when i try to play an audio file
22:02:58Bagdermaking the menu fail
22:03:35DMJCugh, windows
22:03:38DeadManneed to get MP3 decoding lower then really if to make it playback at least as long as iRiver's firmware achieves no? :)
22:03:50DeadManI already went over that aspect though I think
22:04:16preglowthat sentence nearly made my brain explode
22:04:48DeadManI am so eloquent with words am I not? :)
22:05:23Bagdermusepack library source is here:
22:05:30preglowhaha, you are just fine as long as you make sense
22:05:43preglowthat last sentence fried my language center
22:06:02DeadManI thought it made sense. Less Mhz = longer battery
22:06:33DeadManwell iRiver don't run at 120Mhz they run Mp3 decoding a lot lower from what Linus was saying
22:06:54DeadManshrugs. just ignore me most people do
22:07:07Bagderthere are many more factors than just cpu speed
22:07:16DeadManof course :)
22:07:38Bagderlibmusepack is BSD

22:11:04preglowyes, i know
22:11:11preglowamiconn: synthesized
22:11:19preglowamiconn: and very basic sample support, afaik
22:11:27Tanganyway you can try
22:11:29HCleither way, gnuboy just gives me a pcm buffer it wants me to play
22:11:30preglowamiconn: square waves and noise, basically
22:12:01Tangmaybe i can also try with a french contact i know which is quite HA friendly
22:12:38preglowi think a single mail will do fine
22:12:41preglowdon't make an issue out of it
22:12:55TangGood luck :)
22:13:41preglowhe will probably get enough of it once people starts learning of the issue anywa
22:14:09Tangin fact i was hoping
22:14:20Tangthat all the noise about rockbox i did on HA
22:14:49Tangwill make Peter Pavlovski contact the team in a good way
22:15:34TangHum if there is no agreement option
22:15:51Tangmaybe you should try contactig Frank Klemm
22:15:53TangMPC author
22:16:06Tang(but not muselib coder...)
22:16:09preglowwhat good will that do?
22:16:15preglowit's libmusepack we need
22:16:31Tangdon't know maybe he participated to the project
22:16:38Tanganyway as far as i know
22:16:47preglowwe'll see, there's no rush
22:16:55rasherhe did
22:16:57preglowgod knows how many hours of work are left on the codecs we already have :/

22:17:32rasher.. RS file
22:18:09rasherfrom what I read on some forum, the picking of old-bsd might as well be an accident
22:18:20preglowargh, rockbox doesn't even have a bool, just a conflicting enum
22:18:36rasherif whoever picked it was the same as I saw calling lgpl restricting
22:18:52preglowrasher: mno, i think he has chosen it deliberately
22:19:07preglowbut there's always the possibility
22:19:21preglowwhat are the gripes with the old bsd license again?
22:19:36preglowdidn't that have an advertising clause of some kind?

22:29:46Bagderwe can in fact add an exception to the GPL
22:29:48coobi swear the advertising clause means you only have to leave the copyright info in the headers?
22:29:54Bagderto allow libmusepack
22:29:57coobor was that some other bsd license
22:30:04Bagdermany projects to that for openssl
22:30:04rasherif they're insisting on not being gpl-compatible, any hand-crafted license would require a rockbox license-change/addition
22:30:10rashercoob: that's the new bsd
22:30:22rasherand indeed the gpl
22:30:46rasherthe old bsd license requires you to reproduce the copyright info in some way for binary distributions
22:30:55rasherlike printing it when you run the code or something
22:31:26coobdoes having it as an unused variable that can be found with a hexeditor count

23:30:18 Part pillo ("Kopete 0.9.2 :")
23:30:19amiconnYou could try yourself in the simulator too, but let's see whether I find some time
23:30:21HClthough there is no button for it yet
23:30:27HCldon't have access to a simulator
23:30:38amiconnStill working... though at home now
23:30:41HCli'm on a hacked wireless connection that doesn't have the bandwidth to vnc to my server
23:31:42amiconnrasher: u there?
23:31:54preglowlinuxstb: a new mp3 decoder
23:32:03preglowamiconn: i've removed all the standard libs
23:32:08preglowamiconn: headers, i mean
23:32:26linuxstbHave you written an "mp3towav" test plugin for it?
23:32:27 Join jyp [0] (
23:32:33rasheramiconn: yup
23:32:40amiconnpreglow: hmrpf. Then it shouldn't complain when you include codec.h instead
23:32:41preglowlinuxstb: i'm working on it
23:33:00preglowamiconn: but what about stuff like memcpy?
23:33:08preglowamiconn: it uses that as well, and that isn't declared in codec.h
23:34:12amiconnYou'd need an own central header for the codec, or add some more #defines to codec.h
23:34:41amiconnAH, wrong
23:34:52pabsHCl: you really should have hte menu on select, not on mode (for the iriver)
23:34:56rasher < it's in a slashdot comment... but it still looks interesting
23:35:11pabsHCl: it's the easiest button to accidentally hit on the h100, so it should point at a non-game button if possible
23:35:24HCli'll consider it
23:35:27rasherpabs: menu on mode is consistant with rockbox
23:35:31pabsHCl: granted, select is the best button on the gameboy to have there, if any
23:35:48amiconnrasher: I hacked together a funny thing - your logo.rock is now running on the archos player too (you know, the one with the charcell lcd)
23:36:00rasheroh dear
23:36:08pabsHCl: i'll jsut finish the keybinding stuff so this isn't an issue
23:36:19amiconnIt's a somewhat tinly logo though - 16x7 pixels
23:36:24pabsrasher: true, but we don't quit on stop, and that'd be consistent with rockbox as well
23:36:40rasherpabs: if I had my way, it would :)
23:37:11pabsrasher: given the button requirements of rockboy, taht's not really feasable
23:37:37coobhow many buttons do you have
23:37:43HClnot enough.
23:37:49HClwe have 4 buttons
23:37:59HCland we need A,B, select and start
23:38:20coobpossible to detect two at a time?
23:38:32HClonly A + any other
23:38:47HCltechnically, hold could be used but its not very practical
23:38:53HClits assigned to mode switching at the moment
23:38:54pabsHCl: if i get a break from wrk i'll do the keybindings stuff this evening, otherwise it'll have to wait until tomorrow
23:39:01HClyea, take your time
23:39:06HCli'm not really in a hurry either
23:39:15HClmy jaw still hurts like hell from those wisdom teeth being pulled
23:39:26HClso i just do things slowly and when i feel like it
23:39:32rasherDon't mention those
23:39:41HClsorry o.o
23:39:45rasherMine are threatening to annoy me
23:39:54rasherThey might hear you :)
23:39:57HCl :p
23:40:42 Quit jyp ("poof!")
23:41:28Rickis srand() handled automatically by rockbox or should I initialize it with a seed?
23:42:13coobwhy does that always sound vaguely sexual :/
23:42:32HClsomebody whack the pervertedness out of coob
23:45:37amiconnpreglow: The mem*() functions are part of xxx2wav, so the references should be resolved when linking. You need to include the standard header that declares them though.
23:45:55amiconnThat's why I didn't remove all standard headers from the other codecs btw, only stdlib.h is evil
23:48:14rasherrasher: I think you have to seed it
23:48:47rasherrick: that was for you :)
23:49:40 Quit midk ("Leaving")
23:52:35rasheramiconn: Does it run in the sim? patch? I have to see this..
23:53:21amiconnrasher: I'll integrate it into the main logo.rock (made a temporary copy to try my ideas), then commit it
23:53:54amiconnNeed to do variable button definitions for that.
23:54:09amiconn(Player has no up & down nor off)
23:56:01amiconnI also want to change the delta increase / decrease slightly
23:56:14rasherplease do so
23:56:27rasherit seems... strange
23:56:40amiconnCurrently it just adds or subtracts one regardless of direction, so the effect of ech direction pair is switched when the logo bounces
23:57:52amiconnMy change will make the Up button always increase the absolute delta, and the Down button decrease it (down to 0)
23:58:03amiconnLeft/ Right equivalent
23:58:24rashersounds reasonable
23:58:55amiconnAnd yes... the player logo.rock works in the simulator, although a bit slow
