#rockbox log for 2010-12-16

00:02:28eWilln1s:you said, "runtime estimate will never be very accurate". Care to ballpark a margin of error?
00:03:32eWillanyone? Wild guess?
00:04:31LloreaneWill: It's impossible to ballpark since it depends on your use patterns, including filetypes, as well as the condition of your battery and even things like the ambient temperature.
00:04:41LloreanThe best person to ballpark the margin of error for a given device is its owner after experience.

03:08:38soapscorche, you said you could view the moderation log. Who deleted Hendricks266's post?
03:12:41soapLlorean, I see the directory approach as giving 80+% of users a simple path to exactly what they need, and the "all files" toggle approach as giving 100% of users kinda what they need.
03:13:01Lloreansoap: I'm not understanding.
03:13:13LloreanWhat does the directory approach offer that the all files one doesn't?
03:13:41soapesay segmentation. One behavior for one class of files and one behavior for the other class of files.
03:13:51LloreanBut is that really useful/necessary?
03:14:32LloreanIs it particularly harmful if files auto-resume when selected? An "insert shuffled" wouldn't auto-resume, or an "insert" or even selecting a playlist, but clicking on a specific file would.
03:14:35soapI believe it is simply because it is the approach seen elsewhere in the "marketplace" and I feel it is an extension of many people's mental groupings.
03:15:12LloreanI don't know that "it's how they do it on the Clip+" is really that big of a reason to do it.
03:15:19soapand apple
03:15:31LloreanAnd it's also not a reason not to take it a step further.
03:15:32 Quit thegeek (Read error: Connection reset by peer)
03:15:34soap(of course it isn't directory based there, but the pathway to it is similar)
03:15:59LloreanI mean, nobody's really said why they think it wouldn't work well for all files. I don't get the "100% of users kinda what they need" statement.
03:16:08soapI wouldn't characterize the "all files" toggle as "a step further" but rather an entirely different approach.
03:16:15LloreanWhat toggle?
03:16:55soapAm I mistaken in believing your "F" is a selectable option? Or are you saying do it universally?
03:17:10soaplet me reread
03:17:14LloreanAuto-resume all files, but have very explicit situations in which a file is auto resumed.
03:17:59soapie on a new class of insertion?
03:18:27LloreanA new class of insertion, or if a file is launched by single-clicking "select" (or equivalent) on it.
03:18:42LloreanDo not auto-resume if the file is reached by directory change, next track in the playlist, or any other automatic means.
03:19:12LloreanThe new class of insertion is, to me, a way to bring some of the "auto resume mid-playlist" functionality in, and not a key part of what I'm suggesting.
03:19:27LloreanJust a way to bridge the gap between no mid-playlist resumes and having them.
03:19:34soapWhich means explicit insertion of all. "Directory" methodology means implicit new behavior.
03:19:46soap*which means explicit insertion of all is required.
03:19:56LloreanExplicit insertion *if* you want mid-playlist resumes.
03:20:03LloreanAs in, resume file 1, then resume file 2 then resume file 3
03:20:14LloreanI'm against automatic mid-playlist resume even with your segmentation proposal
03:20:22LloreanIt still doesn't resolve any of the problems with it i've brought up.
03:20:27soapAs I said, it's how other do it.
03:20:36LloreanDo they?
03:20:52soapyes, Apple treats podcasts and audiobooks "special".
03:20:59LloreanIf I have three chapters of a book on my ipod, queued up in a playlist, seek in 3 minutes of chapter two, then play chapter 1, it'll be 3 minutes into chapter two when it loads that file?
03:21:20soapthey "segment" music away. Apparently Sansa is playing around with something similar, but file based instead of database based.
03:21:33Lloreansoap: I know the iPod auto-resumes podcasts.
03:21:39LloreanBut does it really auto-resume mid playlist, and with books too?
03:21:52soapThat final query I can't say. I do ask that you limit the questions to one at a time.
03:22:30soapone sec, gotta check on something unrelated.
03:22:48LloreanI still think mid-playlist resuming is much more of a fringe case than people just wanting to select a podcast and have it pick up where they left off.
03:22:57LloreanAnd not think about having to train their syncing program to put it in special folders or whatnot
03:23:56LloreanQueuing a file isn't difficult at all, and I'd say asking people who want mid-playlist resume to queue is a lot more "user friendly" than asking people to restrict themselves to certain organizational structure and to be careful because mid-playlist resume will happen whether they want it or not.
03:24:34saratogasoap: I deleted it, I didn't bother PM'ing him
03:25:47soapLlorean, let's throw it back at the OP / patch man. Personally I think the debate is well framed as "explicit" vs "implicit" methodology.
03:26:25soapsaratoga, I'll pm him. I know it was a fucking idiotic noob statement, but I always try to steer them once.
03:27:06Lloreansoap: Well, I think it's also a case of ease of use. I feel my way it a lot easier to use over all, since it doesn't require your files be organized any specific way *in advance* or anything. While your way is vacation-doable you have to use the file browser's copy and paste if you've done anything wrong.
03:27:35saratogai usually just PM if if move the post, but if its stupid/offtopic/whatever i don't bother since then people feel like they can bug me with more questions
03:27:43LloreanAlso, my way allows access to the functionality of your way, while your way doesn't allow access to the functionality of my way which means I'm stuck with a feature working a way I don't want and no way to resolve that.
03:28:17Lloreansoap: I don't know what you mean by "throw it back at the OP"? He's made it clear his use case is for playlists with multiple resume points within them, so I don't think he's going to be in favour of reducing the capability for that.
03:28:55soapsaratoga, I hear that. I have no problem taking on the role of "someone to take the time to explain the explicit rules" while you do real work. ;)
03:30:04saratogaFred Bauer's new test_codec results for the fuzev1 after his clocking changes are really interesting
03:30:10soapLlorean, on your second point I really don't care, no offense, what either of our expectations are of his reaction. I still think an explicit outline of the counter proposal is polite.
03:30:36Lloreansoap: I don't understand.
03:30:40saratogathey're pretty close to the fuzev2
03:31:08saratogalooks like adding that unboosted option to test codec really encouraged people to think about clocking more :)
03:31:19soapLlorean, I'm not sure where I could clarify, but I'm willing to try.
03:31:27Lloreansoap: What are we going back to him for?
03:31:55LloreanThe question is whether this is the way we want such a feature implemented. No offense to him, but does his opinion matter in that question beyond what his preferred implementation is (which he's demonstrated)?
03:32:37LloreanThe feature breaks down to "which files", "should it be optional", "should how it behaves be configurable", and lastly "which configuration options should be offered?"
03:33:18LloreanYour description has been "all files in a specific location", "yes by physical location of file", "no, behave the same for all files in the folder" and "none" from what I understand.
03:33:26LloreanThough the last two I've inferred and may be quite wrong about
03:34:18LloreanHis patch is "any files", "it is, based on a variety of criteria", "yes", and "criteria for resuming, when to resume, parameters for automatic resuming decisions, parameters for when to store a resume point, etc"
03:36:18soaphis opinion, no. He offered, you countered. I think it is polite to explicitly counter and allow him a known to "counter-counter" against. An explicit opportunity to address concerns either through code or argument. As it is now there is no clear consensus statement in the thread.
03:36:19 Quit designate72 (Read error: Operation timed out)
03:36:36Lloreansoap: I've pretty explicitly described my position in the emails, I thought
03:37:06soapand I don't believe your position is posted as "the answer". That's all I'm asking for.
03:38:09LloreanI have no idea what you mean by that...
03:41:59LloreanDo you want a post that is simply framed as my counter proposal? I did include it in one of my posts, but I haven't posted it explicitly.
03:42:21LloreanI've mostly focused on where I feel there are drawbacks and how I would address them in the hopes that other people might see the difficulties and attempt to address them in other ways.
03:42:26 Quit Keripo (Quit: Leaving.)
03:43:08soap<Llorean> Do you want a post that is simply framed as my counter proposal? I did include it in one of my posts, but I haven't posted it explicitly.
03:43:18soapyes, that is all I'm asking. The thread is a mess IMHO.
03:43:38LloreanBut I don't think we should be focusing on proposals, but "what we want from this feature"
03:44:07LloreanI don't want it to descend into his idea vs my idea, but rather look at what his idea is trying to address and try to decide if that's what we want to address (if it is, his idea's fine) and if not, then start working on how to address it.
03:44:18LloreanJust throwing out proposals doesn't work well if we haven't yet agreed on what problem to solve.
03:44:42saratogashould i close bug reports about ipod accessories and point them at the wiki or do we take bug reports on those now?
03:45:08soapsaratoga, I thought we took them in the one IAP task only.
03:45:46soapsince they aren't supposed to be "bugs" but rather dumps of debug information gathered with accessories not owned by the developers.
03:46:15soap(unless there is a regression, which is a situation I haven't seen addressed)
03:47:20soapLlorean, as I see it, it is not just "throwing out proposals", it is steering the debate.
03:48:07 Quit sasquatch (Quit: WeeChat 0.3.2)
03:48:32 Join sasquatch [0] (
03:51:40Lloreansoap: Okay, I've tried to address what I could.
03:52:12LloreanI'd say a regression is a bug.
03:55:25soapyea, I don't know the specifics of what saratoga is asking about. I just recall previously a desire stated to consolidate all IAP info into the IAP task. Lack of support for an previously unknown device can't really be a bug. I was saying that regression, if it popped up, could be though.
03:55:54LloreanYeah, I don't know if that's how we do it now, but collecting them in one task sounds like a "how we should do it" kind of thing
03:56:22saratogathe one task tells you how to collect debug info, so i guess it makes more sense anyway
03:56:27soapLlorean, I think that's a wonderful email. It consolidates all the points into a single "target" as opposed to responding to bits and pieces here and there.
03:56:28saratogaotherwise the bug reports are kind of useless
03:57:18Lloreansoap: See, from my perspective it's the bits and pieces that should be addresses. Whether or not it should be configurable is to an extent an independent point from which files should use it, unless it's decided that which files should be configurable, etc.
03:57:18soapthough you might as well called me David Hall since that's the email account I had been using previously. ;)
03:57:23LloreanIt's really several features.
03:57:38LloreanAuto resume, auto selection of auto resume files, intelligent resume decisions while playing back.
03:57:51soapyou don't see a value in consolidating all those subthreads?
03:58:05LloreanConsolidating them seems to make it a package deal.
03:58:14LloreanI'm not sure it should be treated as a single feature that's all or nothing
03:58:35LloreanI'd almost say we need to explicitly divide it into separate threads after deciding what the actual features are.
03:58:38soapI don't think a single email denotes a single "take it or leave it" feature.
03:58:47soapI just think it organizes the debate.
03:59:21LloreanPossibly. I think it frames the debate. "We're talking about a whole thing here"
03:59:31soapand, yea, let it split up once the "terms of debate" are agreed upon.
04:00:05soapI see it as "regrouping and refocusing" after a fragmented conversation.
04:00:13LloreanThat makes sense.
04:00:34LloreanI think what it *is* depends on how the other people in the discussion respond to it though. :-P

05:27:03LambdaCalculus37Would anyone have any objections if I lowered the default contrast for the iPod 3G down from 50 to 35? It's very hard to see the LCD straight on with that high of a contrast setting by default.
05:27:25JdGordonnot at this time of day
05:28:26LambdaCalculus37JdGordon: I know, most everyone's asleep by now.
05:32:38saratogamake sure theres only 1 kind of screen, IIRC some of the defaults are chosen as a compromise between screen types on the ipods
05:34:09LloreanLambdaCalculus37: Too dark or too light?
05:34:18LloreanI can never remember if higher numbers on mono means more or less black
05:34:19LambdaCalculus37Llorean: Too dark.
05:34:39LloreanIt may be one of the compromises saratoga mentioned then

05:38:12LambdaCalculus37Llorean: in firmware/target/arm/ipod/lcd-gray.c, the greyscale iPods have #defines for each target (start from line 73).
05:38:52LloreanLambdaCalculus37: Yeah, but I seem to recall some people with one of the grayscale iPods (and I *really* want to say 3G) having the screen completely white and unreadable
05:39:05LloreanI'd check when that contrast value was set and see if there commit message clarifies things
05:39:38LloreanLambdaCalculus37: Some of the iPods have multiple screen types that aren't distinguished in code or necessarily distinguishable, I think
05:41:22LambdaCalculus37The last revision to the file was r26208 by torne, and it was to increase the default contrast of the iPod 3G.
05:42:31LloreanIt'd probably be nice to know how apple gets the contrast right between versions
05:46:11saratogatheres some way to check which screen different ipods have and then adjust the defaults
05:46:27saratogaIIRC some of the older ipods do this, as does the nano2g
05:47:56LambdaCalculus37At least torne mentioned this wasn't the best fix in the comment; I quote: "It seems there is some significant variance between different greyscale ipods of the same model, so it's unlikely that *any* value will be great for everyone. I'm hoping that this is just high enough that the lightest screens aren't totally blank, but not dark enough that the darkest screens are entirely unreadably black ;)
05:48:22LambdaCalculus37Except that I got an iPod 3G where the default contrast was just too dark.
05:58:19saratogai guess you could find someone with a different LCD contrast setting and ask them for their hardware revision number
05:59:03LambdaCalculus37saratoga: Ahh, good call.
05:59:29*LambdaCalculus37 checks his
06:00:00LambdaCalculus37HW rev: 0x00030001; PP version: PP5002D
06:00:44LloreanLambdaCalculus37: If you could tilt it and read it, I think that's not "entirely unreadably black" (in the sense that my impression of the white screens was that some couldn't be seen at all without use of the voice interface or a hand written .cfg to fix them)
06:04:47saratogasame revision i have, mine needs a contrast around 35 to look good

08:18:28eWillthen it's broken
08:19:10the_KyleThis is the same functionality I get if I select insert from the playlist menu if nothing is playing.
08:19:40eWilland it does the same thing if a song _is_ playing −− right?

09:18:07*the_Kyle checks with hotkey on my clip+. I thought it worked the same as using the menu.
09:19:54the_KyleConfirmed. Hotkey is always going to wps here.

09:56:18the_KyleIn Windows, hidden files and directories use a special hidden file attribute. I believe the only potential problem is that files and directories that start with a dot are not hidden unless the hidden attribute is set in the filesystem. The file or directory should be created successfully.
09:56:57the_KyleI could be wrong, however, since the last version of Windows I used was XP. What version are you running?
09:57:33eWillwin7 x64
09:58:26the_KyleThat may explain things somewhat, considering that the filesystem is different on 7 as far as I know. It was supposed to be more flexible though, not less.
09:59:33pixelmamaybe some 64bit thing, I can only test 32bit and am currently running a test on XP so maybe results differ

12:49:53TorneFAT has no concept of a file taking up space unless it contains data
12:51:32TorneIt is physically possible, I guess; you would just have to allocate the blocks in the FAT without writing any data into them, and the resulting file would contain whatever happened to be on those sectors of the disk before
12:51:40Tornebut that's not what fsutil does
12:52:08Torneit explicitly creates a file cotnaining zeros; on a filesystem with sparseness it can do that without allocating any real blocks, but that also won't solve your problem since a sparse file *doesn't take up any space*
12:52:32Tornea 1GB sparse file of zeros doesn't reduce the available space on the filesystem by 1GB :)

17:30:29LloreaneWill: If you'd started the battery bench yesterday, you probably would've finished it already. Is there a reason it must be the fastest possible?
17:31:24eWillI don't see a reason to drag it out? Also, I'd like to be awake when it shuts off so I can get a charge into it immediately (lipo).
17:32:03LloreanThey don't shutdown at "empty" and it won't take damage if it doesn't get charged for a day after it empties.
17:32:32LloreanThey seriously don't expect people to have to know that an empty battery can get damaged and are designed generally to be safe. If you plan to leave it weeks or months without charging after it turns off, that's different.
17:34:22TorneYeah, as long as you charge it again within about 2-4 weeks it'll be fine.
17:34:41Torneit won't selfdischarge to a dangerous level for probably a month

17:36:01Tornealso the shutoff voltage for a given mp3 player is going to be substantially above the point where the cells are at risk

17:40:38eWillSo do any of you lower your cut-off voltage for your personal player? How much extra time do you get?
17:42:55pixelmaI don't think a lot of people do this at all, if there is one person at all
17:43:19TorneThe cutoff voltage in rockbox is not to protect the cells
17:43:35TorneIt's to make sure there's enough power left to spin up the storage and write out settings and resume position
17:43:44Tornei.e. to ensure a "clean" shutdown instead of a hard poweroff
17:44:07TorneIf you lower the cutoff voltage all that will happen is it'll run for slightly longer then it'll hard-poweroff when the regulators fail to be able to generate eonugh power from the lowered battery voltage
17:44:20Torneand that'll *still* be some distance away from the danger point for the cell
17:44:37Tornea lipoly that's discharged down to 3.08V or whatever can't power a 3.3V buck regulator any more :)
17:45:50TorneI'm not certain that this is true for *every* target, but certainly the vast majority of them will power themsleves off by simple regulator failure in plenty of time to save the batteries, whatever rockbox does or doesn't do.
17:47:34Tornei'm not sure why you are wanting to do a battery bench as fast as possible in the first place, thoguh
17:47:45Tornethe point of the battery bench is to determine what a typical runtime for the player is
17:47:56Tornewhich you'd do by having your normal settings, not ones specifically intended to run it down faster
17:48:29Torneit's not for testing the *battery*, it's for testing the effectiveness of rockbox's power management and the efficiency of our code :)
17:48:39eWillall I need is the voltage levels to build an accurate percentage table for the source code.
17:48:59Torneoh, i see.
17:49:10Tornein which case you want to ideally do something that leaves the battery drain constant
17:49:25Tornei.e. no playback
17:49:32Torneand for maximum efficiency, minimal load as well
17:49:41Torneplayback means buffering and the like, which means load fluctuates
17:49:54Torneer, maximum *accuracy* even
17:50:04Tornebut the load level probably doesn't matter too much
17:50:18Torneunless the battery is ancient it won't change the measured voltage much
17:50:20LloreanI'd go for high efficiency so that you end up with a lot of readings at each percentage
17:50:34TorneYeah, so player idle, with backlight off, etc
17:50:49Tornethat will unfortunately take much longer
17:50:52Tornebut it's more accurate
17:50:54LloreanMaybe idle with backlight on?
17:51:01Tornethat's probably ok too
17:51:11Tornebut yeah, playback is gonna make the load decidedly lumpy
17:51:19Tornesice it'll have to do loads more work than average every time it rebuffers

20:03:30LloreanThe nice thing about mpegplayer is that there's sample videos on the download server, and you can disable framerate limiting and frame skipping to get relatively clear numbers for how it's performing.
20:04:11saratogampegplayer is really fast on the the fuze, so its probably not an issue
20:04:17saratogaAPE or AAC+ might be though
20:05:08saratogafreddyb: your test results are interesting because they suggest that boosted performance is extremely poor on the fuze, but unboosted performance is quite good
20:05:26Lloreansaratoga: Well, having an actual number can't hurt and only takes a few minutes to test, though.
20:05:47freddybI tried Dune and got 29.5ish I tried Futurama and got rates from 29 down to 22. Elephant's Dream runs about 30.5 unlimited.
20:06:10LloreanThat sounds like barely fast enough then...
20:06:18freddybI'm not sure why Fututama is slower...
20:06:38freddybElephants Dream is really only 24fps, tho.
20:07:05LloreanYeah, but if the upper limit on framerate is about 30fps, that doesn't give much leeway.
20:07:08saratoga124 might be a little low, although with a 3 level boost scheme it would be fine IMO
20:07:21LloreanYeah, with a 3 level boost and 124 being mid-level it's probably okay.
20:07:34saratogajust use higher clock for mpegplayer and ape
20:07:35LloreanI'm just saying, you don't want the maximum speed to be "just barely above realtime"
20:07:40freddybSaratoga: I should have suspected that memory couldn't keep up with high multiples.
20:07:49saratogayeah most likely
20:08:26freddybLlorean: You really don't notice any dropped frames, the audio is unbroken.
20:08:33saratogathis reminds me, mpegplayer on the fuzev2 and other armv5 devices could pretty easily be made faster by just tweaking the armv6 asm code a bit to remove a handful of v6 only instructions
20:10:35Lloreanfreddyb: With your sample videos maybe, but you should always plan for a little extra leeway, rather than hoping that the slowest you can get the CPU while not being below 29.97 on your test files will be good enough.
20:10:37bertrikI thought the fuze needed a high PCLK (62 MHz) for smooth scrollwheel operation
20:11:09Lloreanfreddyb: The skipped frames may not be noticeable in futurama, which is animation anyway, but may be more noticeable in other things depending on the distribution of them.
20:11:18LloreanAlso, was that the 4:3 or the 16:9 elephant's dream?
20:11:48freddybThis is just my opinion but if I can get more battery life, it's worth it even if I drop a few frames on movies unless it gets to the point that you can visually see lagging or jerking.
20:12:29Lloreanfreddyb: But you're forcing that decision on others. Generally if we're matching or outperforming the OF we then shouldn't introduce inconvenience or reduced functionality just for battery life.
20:12:43freddybLlorean: 224x176 469kbps.
20:12:49LloreanWhat's the fuze's screen?
20:12:55LloreanI thought the fuze was 320x240

20:15:08pixelmafreddyb: I agree that numbers would be better, to me it doesn't sound very comforting
20:15:11LloreanHow about "up to 29.97"
20:15:39LloreanI'm all for better battery life, but not at the cost of reducing offered functionality.
20:16:44saratogaLlorean: i think its premature to discuss this since we don't even know if its desirable to reduce the boost clock ...
20:17:10saratogaif it is we can simply use different clocks for mpegplayer, until then its silly to speculate
20:17:51gevaertsIt's not just mpegplayer though
20:17:57bertriksaratoga, svn r11765 does already reduce the boosted clock, right?
20:18:11Lloreansaratoga: And it's worth bringing up now, since if it's not brought up now what if someone who thinks of this isn't around later?
20:18:27gevaertsIt could mean the difference between being able to to use lots of dsp with high-CPU codecs and having to use high-CPU codecs without any dsp
20:18:47LloreanDo we have a way to test_codec with DSP?
20:19:00LloreanOr do we have an assumption like, "faster than realtime by at least X%" that's generally considered good enough?
20:19:08saratogaLlorean: yes we do
20:19:45saratogabertrik: yes
20:19:56gevaertsThere's a difference between "good enough" and "still better than some other players, but worse than last week"
20:21:18LloreanI just caught the language of "fast enough for me" and thought that it should be discussed what fast enough is for different people.
20:21:29LloreanSince without a discussion of it at some point, it may not come up at a later discussion of the patch.
20:21:32saratogathis has actually been discussed quite a few times
20:21:57saratogagevaerts: yes but its not really an issue
20:22:36gevaertssaratoga: for people who play APE with five EQ bands in use, crossfeed, and pitch adjustment, it is :)
20:22:43saratogano that should still work
20:23:12saratogac3000 with 5 EQ bands should still be fine, and c4000 won't work now anyway
20:23:18LloreanAs long as the ability for mpegplayer to get the speed it needs to playback consistently is in place before a slowdown is implemented that would otherwise make it likely to drop below the framerate of the videos I'm happy.
20:23:25gevaertsok then
20:23:40saratoga5 EQ bands is like 15 MHz
20:23:49LloreanBut as long as the player's physically capable of playing video without dropped frames, I can't see it as being reasonable to make it do so without extremely significant battery life gains (or being in an extremely poor battery life position to begin with)
20:24:00saratogabut really if we're going to have another boost level for mpegplayer might as well have it for ape too
20:24:19LloreanBy "do so" I meant "drop frames" just to clarify
20:24:30gevaertsSwitching to a different boosted level for specific cases shouldn't be too hard I think
20:24:40gevaertsA lot easier than a generic multi-level boost anyway
20:24:57saratogaamiconn had other ideas, but I wanted to just have a codec and plugin API call that increases the boost clock
20:25:06saratogasince its simple
20:25:21LloreanSeems like a good idea.
20:25:32*gevaerts nods
20:25:53saratogae.g. APE calls ci->boost_high(true) which either increases the boost clock or evaluates to a NOP if the device only has 2 levels
20:25:58pixelmado more boost levels really gain this much in everyday use?

20:27:32Lloreansaratoga: Aren't gains (generally) from decreasing unboosted speed in many cases?
20:27:53saratogain this case they'd be from running the CPU clock at a lower multiple of the memory clock

21:30:49saratogai suspect that on arm11 the old way would be quite faster since theres no IRAM and sequential accesses are much faster
21:32:00stripwaxinteresting. probably not too hard. that's related to FS #11268 right?
21:32:23*TheSeven reminds saratoga that there might be ARM11 targets with IRAM one day (iPod Nano 4G)
21:32:25saratogastripwax: not specifically
21:32:25stripwaxoh wait. i'm thinking of libtremor. which tricks did I add to the mdct lib?
21:32:43saratogayou ported the tremor trig table trick to it
21:33:02saratogathe old ffmpeg version used much larger tables with more regular memory access patterns
21:33:06stripwaxcrikey, that old chestnut.
21:33:20saratogabuschel and I noticed that liba52 memory scaling is much different then all the other mdct codecs
21:33:21stripwax'difficult' but not impossible.
21:33:29saratogaand it uses the fft, but not the mdct code

21:35:14saratogaon arm11 the key is basically using lots of ldm, avoding using registers right after you load or multiply to them, and and avoding random memory access patterns
21:35:22stripwaxffmpeg had three tables, iirc. two for the fft part, and a separate one for the mdct.
21:35:42saratogaIMO its probably enough to just special case the 2048 point transform
21:35:45n1sstripwax: if you have time, could you look at FS #11268 some time?
21:35:52stripwaxone of the tricks (reusing the fft tables for the mdct bit, using interpolation ... which I nicked from the original libtremor) could probably still be kept
21:35:55saratogaand unwind the memory accesses for that one, even if it doubles the table sizes
21:36:11saratogasince its the only performance critical one
21:36:30saratogaon arm11 and to some extent arm9 its worthwhile to waste a lot of ram if it allows for more sequential loads

21:38:47saratogathis mp3 project has been a nightmare
21:38:55n1ssaratoga: i managed to make a function that does the mdct doubling and windowing at the same time for tremor but havent' written the asm yet
21:39:10saratogastripwax and i argued abotu doing that a while ago
21:39:57saratogajust make sure you write asm thats not awful on arm11 if you do
21:40:24stripwaxn1s - the benefit comes from reduced load/store presumably?

21:45:12saratogan1s: i think you broke test_codec a week or two ago
21:45:41stripwaxn1s - some of that might be made easier (or harder...) if the imdct_half generates the half output into a different part of the full output array (beginning, middle, end)
21:46:12saratogan1s: when i select speed test with DSP it actually selects the item below that (speed test folder with dsp)
21:46:13stripwaxjust because i made imdct_half generate into the current place doesn't mean that's optimal for your change

21:46:45stripwaxalthough hm, i guess i might not understand what you mean by 'inplace'
21:47:04saratogahmm no maybe i broke it
21:47:34stripwaxyou cache the half-imdct for the next block, and then need to (re)unfold it to do the next block's overlap? so your gain would be halved since you process the same half-imdct twice?
21:48:06n1sstripwax: right now the imdct_half places the output in the upper half of the output buffer, half of this is used to fill in the lower half and half is used to fill in the upper half but it is already in the upper half so it's quite complicated
21:48:17saratogacan't we just use the ffmpeg algorithm for this?
21:48:27saratogaIIRC theres is optimal in terms of mutliplications
21:48:38stripwaxright. i think tremor put it into the middle and then moved things around eithers ide of that
21:48:39saratogai think our wmapro decoder did this correctly
21:48:42n1ssaratoga: the tradeoff is memory iiuc
21:48:49stripwaxyeah, mults is fixed
21:48:54saratogaas in loads and stores?
21:49:02stripwaxyou still have to window every sample on the output side (not on the half-imdct side)
21:49:17saratogathe ffmpeg version uses the imdct half trick and is fully general in that it will work with any transform size
21:49:26saratogamt ported it last summer
21:49:46stripwaxthe challenge is making vorbis do that
21:49:48n1ssaratoga: yes but i think ffmpeg stores the half mdct in a separate buffer and doubles into a new buffer
21:50:10stripwaxand the vorbis window is not symmetric
21:50:17n1sso you need half again as much memory
21:50:25stripwaxdunno about wmapro
21:51:34n1sthe way oi wrote my mdct-double+pwindow function with a special case for the symmetric window case (both overlapped blocks same size9 as this happens more than 90 % of al blocks
21:52:14saratogai don't think the wma ones are symmetric are they?
21:52:23saratogabeen too long
21:53:07n1sthe problem with moving the mdct output in the buffer is that the lower half is used for the input to the mdct
21:55:12n1sbut for non iram challenged targets, doing it with separate buffers would almost certainly be faster
21:55:36saratogathe ffmpeg way seems to use 2048 input samples and some number of output samples i can't easily see because the buffer is shared with a bunch of other things
21:56:04saratogai was actually going to switch wma std over to the wma pro version but never got around to it

23:13:07Bagderright, but I still have zagor do that as I'm not sure how he does those things these days
23:13:46gevaertsAs long as people know they aren't to blame...
23:15:07n1sshouldn't we block known bad compilers or known bad clients?
23:15:34gevaertsThis is neither
23:15:51gevaertsThe compiler just outputs some lines that the build system doesn't expect
23:16:01wodzit isn't bad it just throws additional notes
23:16:54gevaertsIf it was a bad client, I'd block it right away
23:16:55n1sso we should grep the lines for "error"
23:17:08n1sor "warning"
23:17:21gevaertsWell, I did commit a fix, it just needs to be updated on the server
23:17:39wodzBTW what exactly this 'note' mean?
23:17:50gevaertsAnd we want Zagor for that, so it will have to be like this until somewhere tomorrow I guess

23:21:47gevaertsno, it's gcc 4.3 that does this

23:25:29wodzmaybe there is a gcc switch to suppress this 'note' lines?

23:30:03Dreamxtremehow come when i unplug the ipod right away it says around 90% battery
23:30:06wodzinteresting - google doesn't know much about gcc 'note' warnings
23:30:16Dreamxtremedo i need to do a Batt_bench?

23:35:00wodzTurn it on and wait a bit - battery level should rise. HD takes quite a bit of current and battery voltage drops. When hd spins down voltage will recover to some degree.
23:35:12wodzThere is nothing we can do about this
