| 00:33:23 | saratoga | stripwax, mt: do you care if I expose the fft in the codeclib.h header so I can use it in liba52? |
| 00:33:35 | saratoga | for now its a lot easier to use the fft directly then to figure out how to use the mdct itself |
| 00:34:10 | mt | I don't see a problem. |
| 00:34:28 | saratoga | do you think its possible to put windowing code in the codeclib as well? |
| 00:34:46 | saratoga | liba52 should have an ASM optimized version, maybe sharing with another codec is possible |
| 00:37:31 | saratoga | liba52 also folds the windowing into the MDCT post rotation, which is probably a good idea on other codecs as well since it'll save a load/store per sample |
| 00:37:34 | mt | You mean having separate windowing code/function in codeclib, that liba52 could use ? |
| 00:38:07 | saratoga | yeah |
| 00:38:25 | saratoga | or maybe having an imdct_window function |
| 00:38:37 | saratoga | that computes the IMDCT and then windows the data during post rotations |
| 00:38:45 | saratoga | using a window function supplied by the codec |
| 00:39:00 | mt | Yes I was just thinking of that too :) |
| 00:39:02 | saratoga | i think most codecs could use that |
| 00:40:28 | mt | the imdct function itself could be made aware of whether it should window or not, and what window to use. (instead of having 2 separate functions) |
| 00:41:04 | amiconn | saratoga: "compare wav file" only makes sense for lossless |
| 00:41:24 | TheSeven | having separate functions might be marginallly faster |

| 01:13:35 | saratoga | so its probably faster |

| 01:31:47 | saratoga | so i just renamed them |
| 01:32:13 | pamaury | I'm puzzled. Why isn't there a "title" object property with MTP... |
| 01:32:37 | pamaury | Isn't the title of an audio file one of its most important property oO |
| 01:32:43 | waran | saratoga, in way old pascal versions this would have been considered an error by the compiler :) |
| 01:33:24 | | Quit bertrik (Quit: De groeten) |
| 01:34:33 | saratoga | this is c, a struct is just a funny type of array :) |
| 01:35:02 | saratoga | converting short blocks makes no measureable difference in performance, probably because my sample doesn't really use them |
| 01:35:08 | waran | Actually there is no array in c. Everything-is-a-pointer(TM) :D |
| 01:35:42 | pamaury | That's false. |
| 01:36:07 | waran | thats why offset[pointer_var] works just like pointer_var[offset] |
| 01:36:24 | pamaury | In some cases there is a fundamental difference between an array and a pointer. But these are subtle (and useful !) |
| 01:37:00 | waran | example? |
| 01:38:19 | pamaury | Hum, that's should happen on community perhaps ? |
| 01:38:56 | waran | just a tab away. Lets take it to community. |
| 01:39:31 | saratoga | ok liba52 now uses the new codeclib in the mdct branch |
| 01:40:14 | saratoga | speed up is less then 1 MHz, mostly because the ffmpeg and liba52 ffts are identical, the only difference being the ASM in the ffmpeg one |
| 01:41:06 | saratoga | liba52 is really interesting because its the only codec that i know of thats actually faster clock per clock on the gigabeat F then on PP |
| 01:41:54 | saratoga | i'm assuming that means theres not very good IRAM usage in the codec, but looking at the imdct i'm not sure where the problem is |
| 01:47:21 | saratoga | huh looking at it more closely, it does look like its using IRAM extensively |
| 01:47:28 | saratoga | i wonder what the gigabeat F does better |
| 01:47:37 | saratoga | to overcome the IRAM advantage |
| 01:48:31 | Unhelpful | waran: it's not *always* only bad style, if two pointers of different types alias each other, but both have been loaded into registers, the compiler may assume that it can keep the value of *b in a register unchanged after you assign to *a. |
| 01:49:16 | pamaury | Clearly strict aliasing is an optimiazation tool |

| 02:03:25 | saratoga | it'll just be a lot of work that'll have to be undone later |
| 02:08:18 | pamaury | Is there any way to get the sample rate of a file using tagcache tags or not ? iirc, it's related to the frequency in metadata but in tagcache, I'm can't find an equivalent |
| 02:08:56 | saratoga | pamaury: you could call the metadata parser on it I suppose |
| 02:09:28 | pamaury | Yes of course but it's slow so if I can avoid it it's better |
| 02:09:38 | saratoga | although i'm curious why libmtp needs to know what the sample rate of files already on the disk is? |
| 02:09:47 | saratoga | err mpt |
| 02:09:53 | saratoga | mtp |
| 02:10:09 | pamaury | libmtp doesn't it but I'm trying to implement the properties that are usually implemented in MTP |
| 02:10:15 | pamaury | *doesn't need it |
| 02:10:22 | pamaury | And sample rate is one of them |
| 02:10:26 | saratoga | i thought it just checked the files as they came in and then didn't need that once they're on the disk |
| 02:13:40 | mt | hmm .. avoiding the reversal of the spectral coefficients in the imlt in atrac3 only saves 0.11 MHz :/ |
| 02:15:23 | saratoga | i remember looking at requantization in atrac last summer and thinking we could speed that up a bit |

| 02:24:37 | saratoga | tetsuo55: it won't be, its not really applicable to ffmpeg |
| 02:25:06 | tetsuo55 | its a lossy speedup? |

| 02:26:04 | saratoga | or at least not obviously applicable to ffmpeg |
| 02:27:11 | tetsuo55 | doesnt look that obvious to me |
| 02:27:19 | mt | Maybe that user was using an old revision . the thread was in october, ~2 months after the optimizations. |

| 02:33:17 | tetsuo55 | saratoga > i just checked the ffmpeg site through google, seems like there is a big interest in fixed point math, the devs try to have all codecs have 2 codepaths, fixed and floating |
| 02:33:37 | tetsuo55 | theres even a fixed point math port from rockbox to ffmpeg on the to-do list |
| 02:34:05 | tetsuo55 | but not for this particular codecd |
| 02:34:29 | mt | it's in atrac3.c .. it's now using the new mdct in the mdctexp branch, so we'd just have to change those few lines when merging back. |

| 02:36:35 | tetsuo55 | lots more here: http://www.google.nl/search?hl=nl&safe=off&q=fixed+point+ffmpeg&btnG=Zoeken&meta=&aq=f&oq= |
| 02:37:14 | saratoga | well when they get around to adding a fixed point decoder we should see about giving them optimizations for it |
| 02:37:23 | tetsuo55 | anything that improves ffmpeg is a win in my book |
| 02:37:33 | tetsuo55 | saratoga dont expect that |
| 02:37:57 | tetsuo55 | ffmpeg has a clear policy, that they dont really work on feature requests, and that stuff like this has to be submitted as a patch |
| 02:38:12 | tetsuo55 | rockbox clearly has a fixed point local version, that could be upstreamed |
| 02:38:12 | saratoga | yes I know, i've spent a good deal of time over there |
| 02:38:38 | tetsuo55 | and its probably not just atrac, but many other codecs |
| 02:39:04 | tetsuo55 | may sound obvious, but ideally all codec updates will occur in the ffmpeg trunk, then get synced into rockbox |
| 02:39:46 | tetsuo55 | i have a similar problem with my project, unfortunately my patches are really only usefull in my project, as they are api hooks |
| 02:40:08 | mt | tetsuo55: They have a fixed-point cook patch that's been sitting in there (interesting patches) for ages, and we actually used that patch in rockbox - it decodes 200+% realtime btw - and it has yet to be committed. |
| 02:40:09 | tetsuo55 | but if we find anything like memory leaks, etc.. we quickly submit a patch upstream |
| 02:40:20 | tetsuo55 | damn |
| 02:40:22 | tetsuo55 | i want that |
| 02:40:22 | mt | s/in there/in their/ |
| 02:40:22 | tetsuo55 | :P |
| 02:40:58 | mt | Well, You have it in rockbox already. :) |
| 02:41:02 | tetsuo55 | i assume you harras tem all the time in #ffmpeg-dev |
| 02:41:04 | tetsuo55 | i dont |
| 02:41:06 | tetsuo55 | :( |
| 02:41:11 | * | tetsuo55 has a D2 |
| 02:41:29 | tetsuo55 | i only play with rockbox in the sandbox on windows |
| 02:42:04 | tetsuo55 | i use cook audio ALL the time on the pc though |
| 02:42:19 | tetsuo55 | and that codec needs a lot of TLC |
| 02:42:31 | Llorean | Wouldn't trying to keep all of our code in sync with theirs by submitting it to them and updating off of their version just create a ridiculous bottleneck in the rate at which codec improvements could occur unless all Rockbox codec contributors had ffmpeg commit access too? |
| 02:42:56 | tetsuo55 | only 1 rockbox dev really needs commit access |
| 02:43:19 | Llorean | This 1 dev being magically available 24/7/365? |
| 02:43:29 | tetsuo55 | but yes, the bottleneck means you need a local ffmpeg branch that you can keep working on, while you wait for the offical ffmpeg trunk to catch up |
| 02:43:50 | tetsuo55 | i have to go to bed now, more here http://producingoss.com |
| 02:44:08 | Llorean | Also doesn't that mean more work for Rockbox devs to fit the code into ffmpeg, rather than ffmpeg devs who know their code doing that work? |
| 02:44:32 | tetsuo55 | ideally things would go smoothly on irc |
| 02:44:32 | | Quit pamaury (Quit: abort();) |
| 02:44:43 | tetsuo55 | and snippets of code would turn into commits swiftly on their side |
| 02:45:05 | tetsuo55 | instead of slowly in a mailing list that nobody cares about |
| 02:45:27 | saratoga | i don't think trying to convert all of ffmpeg to fixed point makes much sense |
| 02:45:35 | saratoga | it'd just make a mess of their codecs |
| 02:45:43 | tetsuo55 | i agree, just the parts your already doing anyway |
| 02:45:47 | saratoga | combined fixed/float codecs are ugly and difficult to work with |
| 02:46:03 | tetsuo55 | i would guess rockbox has a large pile of patches, that get applied to ffmpeg in some way |
| 02:46:14 | saratoga | we don't actually use ffmpeg itself |
| 02:46:18 | tetsuo55 | (locally) |
| 02:46:32 | saratoga | we do adapt [by rewriting] some of their code though |
| 02:46:33 | Llorean | I'm just not really sure I see the 'benefit' of creating additional work to integrate code to another project that has its own devs perfectly capable of working with us to do that. |
| 02:47:26 | tetsuo55 | saratoga so you only use small bits of ffmpeg, in your own codebase? |
| 02:47:50 | saratoga | a few of our codecs started out as ffmpeg codec, and one ffmpeg codec started out as a rockbox codec, but we do very different things |
| 02:48:04 | tetsuo55 | Llorean > the idea is that you change something, to the default ffmpeg file, and then provide that patch upstream, and the ffmpeg devs take it from there, and ask you for input when needed |
| 02:48:29 | tetsuo55 | Llorean > i do agree that its hard to swallow, to have to do the whole thing yourself |
| 02:48:39 | Llorean | tetsuo55: That also doesn't really reflect the real-world situation |
| 02:48:50 | tetsuo55 | unfortunately it doesnt :( |
| 02:48:52 | Llorean | As saratoga said, we're not really a port of ffmpeg. They're not really, realistically, "upstream" |
| 02:49:04 | saratoga | tetsuo55: what is involved in converting a codec to fixed point? |
| 02:49:05 | tetsuo55 | yeah, i just understood that just now |
| 02:49:22 | Llorean | It's a good idea to try to learn about the situation before you make suggestions on how to 'improve' it. ;) |
| 02:49:42 | tetsuo55 | i wrongly assumed it was similar to what my project does, include ffmpeg and wrap around that (with some minor patches to the ffmpeg source) |
| 02:50:09 | tetsuo55 | saratoga > LOTS of beer |
| 02:50:45 | saratoga | if thats your answer then maybe you shouldn't be trying to tell people who have some idea what they're talking about how to do things |

| 02:58:01 | saratoga | hence my original comment that most of it isn't applicable to ffmpeg |
| 02:58:46 | tetsuo55 | didn't most codecs used to be fixed point anyway? |

| 13:53:32 | moos | oh ok, still working on it... If you need testing on big discs (aka big cache) I could |
| 13:54:15 | moos | pamaury: the complete scan rework. I didn't find time yet to fix my laptop problems (ie no dev env) |
| 13:55:12 | pamaury | Ah. I tested it and got not change. JdGordon also tried it and apparently it is working. I can't seen any reason for this to fail except if my trick with the FAT code is wrong but if think it's ok. |
| 13:55:30 | pamaury | moos: but yes, if you can try it on a big disc this would be great |
| 13:56:21 | moos | do you get improvements? I mean: is the scan faster now? |
| 13:57:02 | moos | pamaury: I will retry to get e dev env here, sinon, you will have to build me a beast build patched |
| 13:57:22 | pamaury | On my device I can't see a difference because I haven't got some many files. That's why a test on a big disc would be useful. |
| 13:57:44 | pamaury | I'm not sure it will scan faster with this because beasically it does the same thing but uses less memory |
| 13:58:17 | moos | okok |
| 13:58:31 | moos | did you get Slasheri's attention about it? |
| 13:58:54 | pamaury | The only possible improvement is the old code did depth first scan, this one does breadth first search so if the directory is contiguous, perhaps this is faster but it's unlikely. |

| 14:05:17 | gevaerts | it doesn't |
| 14:06:06 | pamaury | Hum. Maybe I'll go through a little review of the code to see if I can gain some place. Does it use tagcache or not ? |

| 14:27:18 | tetsuo55 | moos > CIA is down |
| 14:29:10 | pamaury | gevaerts: from what I saw, tagcache uses an enormous stack (16Kb !!!) so there is some work to be done in this area perhaps. |

| 14:30:35 | pamaury | True. But there perhaps are other areas to optimize. tagcache is kind of a fragile masterpiece so it's not the easiest one to tweak. |

| 14:44:31 | amiconn | Rombox, standard in-flash rombox and disk-based rockbox (.ajz/.mod) all come in the same package... |
| 14:45:43 | | Quit Farthen (Ping timeout: 256 seconds) |
| 14:45:57 | gevaerts | We could consider changing rombox builds to be separate builds, without e.g. tagcache. That wouldn't be a very nice solution though |
| 14:48:56 | amiconn | And it wouldn't work |
| 14:49:24 | amiconn | If you leave out tagcache (or any other non-trivial feature), language and voice ids change |
| 14:50:33 | gevaerts | yes, they'd have to be fully separate builds. Not good |
| 14:50:35 | amiconn | That means loading disk-based rockbox (which is required before flashing if rombox is currently running) would mess up the whole ui |
| 14:50:59 | gevaerts | You could have an equivalent disk-based rockbox with it |
| 14:51:47 | gevaerts | Then people would just have to choose when installing: full rockbox with all features, or rockbox light with less features, but longer runtime |
| 14:52:05 | linuxstb | Move the "optional" feature strings to the end? |
| 14:52:19 | gevaerts | that would still break the plugin API |
| 14:52:47 | * | gevaerts doesn't like this sort of "solution" at all |
| 14:53:03 | amiconn | Runtime isn't really different on te Ondios |
| 14:53:18 | pixelma | there are still two targets that have rombox currently and for others it has been broken for quite some time (different time depending on the target) |
| 14:53:23 | amiconn | But the larger buffer has other advantages, e.g. being able to view larger jpegs etc |
| 14:53:41 | pixelma | or using a better quality voice |
| 14:53:54 | *** | Saving seen data "./dancer.seen" |
| 14:54:20 | amiconn | In fact runtime might be *slightly* worse with Ondio rombox |
| 14:55:16 | amiconn | This is because the RAM has a 16 bit data bus, while the ROM only has an 8 bit bus. Hence code execution from ROM is slower, and the cpu gets less sleep |

| 16:52:04 | danopia_ | i can mirror rockbox onto git :P |
| 16:53:06 | domonoky | does some one know what happens if i load a cfg with settings which only exist for color targets on a non-color target ? |
| 16:53:55 | domonoky | are the non-existing settings safely ignored ? (thinking about checking theme cfgs on the theme page) |
| 16:53:56 | rasher | I also seriously doubt the slowness there was scm related |
| 16:53:58 | *** | Saving seen data "./dancer.seen" |
| 16:55:00 | rasher | More likely a holdup with the cia notification |
| 16:55:08 | rasher | Since cia appears to be gone |
| 16:55:29 | domonoky | also what happens with non existing setting values ? for example "selector type: bar (color)" on a greyscale target ? |
| 16:56:15 | domonoky | true, a timeout in the commit hooks is probably the cause for this slowness. |

| 17:55:10 | amiconn | And the warnings/errors haven't been silenced, the rombox build step has been deactivated for the targets where it doesn't fit anymore |

| 18:11:44 | Buschel | *weird |
| 18:12:45 | Unhelpful | pamaury: why not? initdata is used to provide the initial values of writable arrays, isn't it? so it needs to be copied to RAM anyway, doesn't it? it's at least worth seeing if compressed initdata + a decompressor will fit. |

| 18:13:03 | Unhelpful | assuming it's not compressed already, of course... |
| 18:14:52 | pamaury | That works only for initdata which is RW no ? Because otherwise will put it in .rodata and that will never end up in ram |
| 18:15:14 | amiconn | There isn't that much int data |
| 18:15:34 | amiconn | Although we could also compress all .icode, .irodata and .idata |
| 18:15:53 | amiconn | Not that much either - SH7034 has 4KB of IRAM |
| 18:16:35 | Unhelpful | amiconn: is "part of the data is compressed" perhaps something that could be done by the bootloader? i gather that bootbox is responsible for decompressing non-rombox firmwares... or am i mistaken? |
| 18:16:56 | amiconn | Not bootbox, but the flash loader |
| 18:17:20 | amiconn | The flash boot on archos is a bit more modular than on the other targets |
| 18:18:37 | pamaury | What exactly does the boot time looks like on an archos ? First there is the flash boot and then ? |
| 18:19:42 | | Join moos [0] (moos@rockbox/staff/moos) |
| 18:20:56 | amiconn | It depends on whether the archos is flashed (flashing is optional, and not all boxes are flashable), and where you have a box with or without bootrom (the latter variant is rare) |
| 18:21:53 | pamaury | if it's flashed and with a box ? |
| 18:22:39 | Unhelpful | maybe we should work further on making features that make no sense on archos optional... the bitmap loader already doesn't support scaling on mono targets, but we could probably make a smaller bitmap loader specialized for loading bitmaps to mono. |

| 18:23:33 | JdGordon | it broke just before 3.5 branch |
| 18:24:02 | amiconn | The standard way (without rockbox in flash): (1) CPU boots from its internal rom (it's a mask rom, not changeable). (2) The boot rom starts the archos firmware in flash. The loader that's part of it copies the rest of the firmware to RAM, then jumps there. (3) The firmware looks for an on-disk update (archos.mod for Players, ajbrec.ajz for the others). If it exists, it loads and starts that one |

| 18:27:46 | amiconn | Boot sequence changes as follows: (1) CPU boots from its internal rom (it's a mask rom, not changeable). (2) The boot rom starts our flash loader. (3) The flash loader checks buttons, and does one of three actions depending on that. (a) start the second firmware image. This is the default, full rockbox, which is updated by rockbox_flash.rock |
| 18:29:35 | amiconn | (b) start the first firmware image. This is the backup - bootbox, a cut-down rockbox that just handles charging and usb. It is there in case the default image is broken. (c) start minimon, a mini serial monitor for debugging/testing |

| 20:49:17 | linuxstb | amiconn: gevaerts was asking the other day about using asm-optimisations in the sim (for his n900). So I guess using MMX optimisations are the same issue.... |
| 20:49:27 | amiconn | Do we want to enable mmx permanently (for x86, that is)? |
| 20:50:00 | amiconn | On x86_64, mmx is standard, so we can do that, but not all 32 bit x86's support it |
| 20:50:14 | amiconn | That said, all non-stoneage x86's do |
| 20:50:32 | rasher | I'd say we can safely require mmx for the sim |
| 20:51:14 | amiconn | Intel supports it since Pentium MMX, AMD since the K6. Cyrix 6x86 does as well (it even implements a slightly extended variant) |
| 20:51:38 | linuxstb | Although maybe with the ability to disable it? |
| 20:52:01 | amiconn | The way libdemac is built doesn't allow runtime detection (currently) |
| 20:52:13 | rasher | Unless it's fairly simple - I wouldn't spend much time on letting it be disabled |

| 20:54:34 | | Join mc2739 [0] (~mc2739@rockbox/developer/mc2739) |
| 20:54:41 | linuxstb | amiconn: Yes. |
| 20:54:45 | gevaerts-phone | linuxstb: those ARM defines do the trick, together with enabling one or two more files in SOURCES |
| 20:55:04 | gevaerts-phone | That makes everything build, axcept ape |
| 20:55:18 | amiconn | What happens with ape? |
| 20:55:46 | sudoman | Buschel: right now it's at the smallest setting. (it says there's about 126h on a full charge, but that's a known problem) i think that setting doesn't affect the charge percent calculation anyways. |
| 20:55:46 | linuxstb | Did it give you a decent speed-up? |
| 20:55:50 | gevaerts-phone | I'll tell you later, when I'm home |
| 20:56:26 | gevaerts-phone | It didn't fix the audio dropouts, I didn't do test_codec tests |
| 20:57:31 | Buschel | sudoman: what iPod do you use? |
| 20:57:42 | sudoman | Buschel: ipod 3G |
| 20:58:53 | sudoman | Buschel: it might be relevant that i installed a replacement battery a couple of years ago. i only get about 2.5 hours out of it at this point. (but that might not be from a completely full charge) |
| 20:59:11 | AlexP | % is from voltage IIRC |
| 20:59:22 | AlexP | So if the battery is buggered that is probably it |
| 20:59:36 | AlexP | It can't supply the current required so shuts down early |
| 20:59:44 | sudoman | Buschel: there's no way of telling with the rockbox firmware as it doesn't say when the battery is charging or not, but the apple firmware does |
| 21:00 |
| 21:00:02 | sudoman | AlexP: is there a way to fix that? |
| 21:00:08 | Buschel | sudoman: ah ok. The iPod 3G has no correct estimation implemented as there were no reliable battery runtime measurements availabe. |

| 21:00:23 | AlexP | If it is a dead battery |

| 21:00:54 | Buschel | sudoman: We could easily implement the needed changes if you could do a battery bench with a good working (new?) battery. |
| 21:00:58 | domonoky | the % comes from the voltage AND the battery curve in the powermgmt-xxx.c files. so a different battery could also cause "low battery" shutdowns. |
| 21:01:15 | AlexP | ah, OK |
| 21:01:29 | AlexP | If the discharge curve is different |
| 21:01:48 | domonoky | or maybe the battery curve and min values were never calibrated for ipod 3g ? |
| 21:01:54 | sudoman | would it not be useful to submit a curve with my current battery? |
| 21:01:57 | AlexP | could be |

| 21:03:42 | AlexP | hmmm :) |
| 21:04:16 | AlexP | sudoman: I'm not sure to be honest |
| 21:04:24 | Buschel | sudoman: it could also be a replacement battery. but we need to know the capacity in mAh |
| 21:05:41 | domonoky | current values for ipod3g: 3,37V = 0%. 3,38V is considered dangerious and 3,02V is shutdown. |
| 21:05:45 | sudoman | ok. is this issue related?: when charging from a "dead" battery, the percent quickly goes up to 100%. does that mean the charging is terminated early, or that charging is continuing and that the calibration needs fixing? |
| 21:06:23 | domonoky | there is also a curve for charging, which is probably wrong too. |
| 21:06:28 | Buschel | sudoman: and of course you should perform the test following the standards (e.g. clean restart after full charge, looping a folder that is larger than the iPods RAM) |
| 21:06:38 | sudoman | huh, my player shut down at 3.82V |
| 21:07:14 | AlexP | domonoky: It'll also shutdown if it fails to spin up the disk right? |
| 21:07:16 | sudoman | ^ (from my last test which didn't follow all of the standard rules) |
| 21:07:24 | domonoky | 3.82V should show ~50% with the current battery curve. |

| 21:08:04 | sudoman | AlexP: it managed to write the value to disk one second after the previous entry, so it must not have been a disk issue |
| 21:08:28 | AlexP | I don't quite follow that sentence :) |
| 21:09:37 | domonoky | sudoman: did it show the "low battery" warning before shutdown ? |
| 21:09:56 | sudoman | the battery benchmark writes a new set of data points every minute. when the disk is accessed, it writes them to disk. my final value is listed as being one second later than the previous, which implies that it detected the low power and wrote to disk |
| 21:10:04 | sudoman | domonoky: no it did not |
| 21:10:15 | AlexP | sudoman: Does it? |
| 21:10:22 | AlexP | Does battery nench work like that? |
| 21:11:07 | pixelma | as far as I know battery_bench caches values in RAM until the next spinup (e.g. for rebuffering) |
| 21:11:09 | sudoman | i was accessing a context menu or something. i guess it could have been a bug because i've experienced shutdowns while using the menus before. thought it was just a coincidence |
| 21:11:18 | domonoky | sudoman: then it probably wasnt a shutdown based on the values from the battery curve. |

| 21:13:27 | domonoky | sudoman: either that, or a bug :-) |
| 21:13:48 | amiconn | gevaerts: Could you paste the output of gcc -E -dM - < /dev/null | cut -c 9- | sort on your n900 somewhere? |
| 21:14:04 | sudoman | could be a bug. i do remember having a bug/power-failure(?) at 40% once... |
| 21:14:17 | Buschel | sudoman: it could also have been a simple crash. |
| 21:14:27 | domonoky | if you expirienced shutdowns while using context menus before, it looks more like a bug. |
| 21:14:45 | sudoman | how is a crash different than a bug? |
| 21:15:40 | Buschel | sudoman: could you please be so kind and perform a battery bench without touching your ipod? ;o) as soon as there is a full reasonable battery bench we can change the code to allow (more or less) proper estimation of runtime. |

| 21:27:51 | sudoman | pixelma: why is charging faster on the apple firmware? |
| 21:27:58 | Unhelpful | amiconn: how hard would it be for the flashloader to handle a firmware with a compressed and uncompressed section? presumably the compressed portion would need a list of offsets and lengths, or it could be decompressed contiguously with start/end addresses for each section used to move things to their proper places. |

| 21:33:26 | amiconn | I think it would better to make this part of crt0.S (which does the copying anyway, so it could uncompress instead of copying) |
| 21:37:17 | amiconn | The question is whether it's worth it. We're talking about ~8KB of data (probably compressible to half of that) |

| 23:35:20 | Buschel | mt: is mdctexp faster for atrac on coldfire as well? |
| 23:36:14 | JdGordon | pixelma: no, i'll try that now |
| 23:36:40 | mt | Buschel: I'm not sure, the measurements were all done on arm targets. |
| 23:37:09 | domonoky | JdGordon: and when you commit the fms patch, remember that the themesite needs updates for that. (since my newest addition it wont a accept a fms without changes, because thats a unknown theme cfg value ) |
| 23:37:17 | Buschel | mt: somebody should support you with some measurements... |
| 23:37:32 | JdGordon | domonoky: arg, is that a recent change? |
| 23:37:39 | JdGordon | I thought it didnt go through the .cfg? |
| 23:38:23 | domonoky | JdGordon: yes, today. But you can add new allowed settings via the admin interface. (still needs changes to actually check a fms with checkwps) |
| 23:38:24 | JdGordon | ok, the hardcoded fms passes checkwps |

| 23:38:50 | JdGordon | I'm not an admin on the theme site |
| 23:39:06 | pixelma | the one with %pm in the conditional? |
| 23:39:11 | Buschel | mt: atrac's iqmf synthesis filter is nearly fully optimized on arm now. without dropping precision and/or dropping coefficients there is not much left to do. |
| 23:39:11 | JdGordon | yeah |
| 23:39:31 | domonoky | JdGordon: ask rasher to give you admin access :-) |
| 23:40:14 | rasher | domonoky: surely you have access to that as well - or are you just bothering me because I'm responsible for the current lack of admin interface for this? :) |
| 23:40:17 | JdGordon | its more fun to annoy others to fix ti |
| 23:40:23 | mt | Buschel: Wouldn't say no to cf measurements of course :) |
| 23:41:20 | domonoky | rasher: no i cant do that. my login doesnt have write access to the db, i think |
| 23:41:32 | mt | Buschel: Do you think there's something else that could be optimized ? |
| 23:41:55 | JdGordon | arg, I reckon there is enough duplicated code for the skin init/display stuff that we could get the ondio rombox going again, but that will only give us another few weeks... so what's the point? |
| 23:41:59 | rasher | domonoky: ah yes, the sqlite db had the wrong permissions at one point - it should be fixed now |
| 23:42:12 | domonoky | ah, then i can do it too :-) |
| 23:42:13 | rasher | domonoky: this also meant that checkwps wasn't able to update the db from cron |
| 23:42:37 | pixelma | JdGordon: the point is that it's always nice to save bin size/ RAM usage |
| 23:42:53 | JdGordon | pixelma: the previous tests, you were just getting a blank fm area? the statusbar kept updating? |
| 23:43:01 | Buschel | mt: i had some questions in the area of joint stereo coding. especially the INTERPOLATE macros could be optimized and the div16 calls can be avoided via lookup tables... |
| 23:43:03 | mt | Buschel: I tried the the reversal of spectral coefficients of odd bands outside the imlt, but the gain was embarrassing; 0.16% on arm :-) |
| 23:43:47 | pixelma | JdGordon: statusbar was displayed, yes. I didn't pay much attention if it was updated or not though |
| 23:44:23 | JdGordon | yeah, ok, if you could try the splash change and let me know if it ever shows up that would be great |
| 23:45:25 | Buschel | mt: afterwards i saw that i have no file with joint stereo at all :/ |
| 23:45:53 | Buschel | mt: nothing to optimize or verify... |
| 23:46:04 | mt | Buschel: Yes, was just going to point that out |
| 23:46:45 | Buschel | mt: nevertheless: is the calcualtion in fastSqrt(...) correct? |
| 23:47:03 | Buschel | mt: or better: the way it is used? |

| 23:48:46 | Buschel | mt: e.g. when ind==7 -> ch[0]=ONE_16 ch[1]=ONE_16. but when using ch[0]=ONE_16 withni the fastSqrt(...) formula the result is ch[1]=sqrt(ONE-16). |
| 23:48:48 | mt | Buschel: I did some tests against the floating point decoder back when I was still converting the codec to fixed point, and it was correct. |
| 23:49:10 | Buschel | mt: could you test with joint stereo files? |
| 23:49:29 | pixelma | JdGordon: and if it really is duplicated code, a cleanup will help maintaining the code a lot |
| 23:49:44 | mt | Buschel: Guess I have to now ! .. I'll look for some. |
| 23:49:45 | pixelma | if you remove it, I mean |
| 23:50:24 | Buschel | mt: we should make a lookup table for ch[0] and ch[1] to avoid the calculations. |
| 23:50:27 | JdGordon | no, well the case can be made that it makes the code harder to read |
| 23:50:35 | Buschel | mt: if you find some, give me a message ;o) |
| 23:50:52 | mt | Sure. :) |
| 23:52:50 | pamaury | mt: I don't unerstand why the build_dev tables show 15Kb. On my computer I had a 30Kb augmentation irrc. But perhaps I made a mistake |
| 23:54:18 | pixelma | the delta table takes bin size and RAM usage into account (and takes the average) |
| 23:54:22 | | Quit asjsafjoa (Quit: Page closed) |
| 23:54:48 | mt | pamaury: I don't know about that - I was just asking because saratoga said 30KB, while your message said 30Kb i.e < 4 KB. I was just confused whether you actually meant bits or bytes. :) |
| 23:55:08 | | Join fml [0] (~5dd2e02e@giant.haxx.se) |
| 23:55:43 | pamaury | mt: I meant bytes |
| 23:55:48 | pixelma | pamaury: if you hove over a value in the table you can see both in the tooltip |
| 23:56:08 | fml | JdGordon: isn't there a signedness mismatch in buffer in skin_font and buffer_start in font |
| 23:56:33 | pamaury | mt: why the table show: bin: -420, ram: -30xxx and a global -15000 ? |
| 23:56:42 | B4gder | pamaury: average |
| 23:56:50 | B4gder | as pixelma explained |
| 23:57:23 | * | gevaerts thinks that average is a bit meaningless there |
| 23:57:27 | pamaury | Ah, I didn't see pixelma comment :) I've been afk for the last hours |
| 23:57:35 | rasher | Maybe it should just be the sum? |
| 23:57:39 | * | pamaury agrees with gevaerts |
| 23:57:50 | B4gder | sum might be better, yes |
| 23:57:51 | pixelma | pamaury: it was just below your statement |
| 23:57:52 | rasher | Or else it should be a score, rather than a delta |
| 23:58:11 | gevaerts | sum is also wrong. ram includes bin |
| 23:58:48 | pamaury | take max ? |
