| 00:30:33 | Blue_Dude | I'm looking at doing non-destructive realtime mixing in pcmbuf, but I'm going to need to take 64K of RAM for buffer space to do it. Are there any targets where this will be a real problem? |

| 00:39:06 | kugel | Blue_Dude: the clip has 176400 bytes of pcm buffer |
| 00:39:35 | Blue_Dude | One second of audio? Ouch. |
| 00:39:42 | kugel | but it's a flash target, we can possibly increase that if needed |
| 00:40:02 | Blue_Dude | I need a bit more than a third of that. |
| 00:40:19 | kugel | and it's a fast target, it doesn't even need to boost to keep it full in most sitations |
| 00:41:03 | kugel | all other targets should have some 500k, I don't think those will be a problem |
| 00:41:28 | Blue_Dude | Right now I'm trying to allocate space. I've still got to figure out how to keep mixing in real time without killing the CPU or other threads. |
| 00:42:32 | Blue_Dude | It's possible I'll have to steal time from the pcm interrupt callback. I don't know yet how that will affect performance. |
| 00:44:55 | Blue_Dude | I need a process that runs every 5 to 10 ticks to check up on whether a mix is necessary, then perform one if it is. Is there a mechanism to do that? Create a thread and just sleep it for a while if it's not needed? |
| 00:45:34 | bughunter2 | spawning processes is cheap on unix, you could simply use a cron job + shell script |

| 00:50:15 | Blue_Dude | Thinking out loud: I could have a mixing thread that stays frozen until an event comes along that requires mixing (voice playing at the same time as playback), then thaws and begins a non-destructive mix. As soon as the chunk is beginning to be built, it becomes the next chunk to be read by the pcm, and this continues as long as there are multiple inputs. When we're down to one input, the... |
| 00:50:17 | Blue_Dude | ...pcm is redirected to the actual buffered material and playback (or voice) resumes as normal, and the thread freezes. |

| 01:08:03 | Blue_Dude | Maybe it's time to think about building smaller chunks. That increases overhead since there's some housekeeping for every chunk change, but it would increase responsiveness. |

| 01:15:29 | Blue_Dude | We play whatever shows up in the pcmbuf by throwing it directly at the DMA. If there's voice coming in it's destructively mixed into the buffer. |
| 01:15:51 | saratoga | what do you mean by destructively mixed? |
| 01:16:18 | Blue_Dude | Meaning that the mixed material is forever changed. You can't "unmix" it after it's done. |

| 01:17:21 | Blue_Dude | Or even stop playback. That also stops voice and effects. |
| 01:17:37 | saratoga | so if rockbox is stopped you lose the voice ui? |
| 01:17:43 | *** | Saving seen data "./dancer.seen" |
| 01:18:32 | kugel | I don't think the "destructiveness" is a huge problem |
| 01:18:48 | Blue_Dude | No. If you're playing a voice clip while playback is stopped, the clip plays. But if you're playing a voice clip *while* playback is playing, then the voice clip also stops. |
| 01:18:54 | kugel | it doesn't really matter if we'd lose the current voice clip due to (un)pausing |
| 01:19:07 | kugel | the big problem is that there's no voice while being paused |
| 01:19:11 | Blue_Dude | kugel: it is if you try to continue a voice clip and also stop playback. |
| 01:19:32 | kugel | yes, but that's a very improbable situation |
| 01:19:42 | kugel | (I think) |
| 01:19:54 | | Quit lostlogic ("leaving") |
| 01:20:10 | Llorean | Also, just moving up or down an entry in the menu again gets the next voice clip playing in that situation, no? |
| 01:20:25 | Llorean | So while it's a problem, it's a quirk that can be worked around rather than something that drastically hinders usability, right? |
| 01:20:29 | Blue_Dude | Same problem. Pausing currently paused the DMA. I'd like to just stop the input to the mixer and let the voice playback continue. |
| 01:21:11 | kugel | I'd rather have the bigger issue fixed first. the destructiveness can be dealt later with |
| 01:21:56 | Blue_Dude | The bigger issue can't be solved without the destructiveness issue. If you stop playback, then the voice clip that has already been buffered is lost. |
| 01:23:00 | Blue_Dude | And when playback resumes, any voice or effects that were already mixed into the buffer will play. |
| 01:23:45 | Llorean | Blue_Dude: When resuming from *stop*? |
| 01:24:16 | Blue_Dude | No. Resuming from pause. Stop clears the buffer. |
| 01:24:27 | Llorean | Okay, I was going to say that seemed strange. |
| 01:24:37 | Llorean | I was confused because the line before you were talking about "stop" behaviour |
| 01:24:58 | Unhelpful | kugel: if eabi builds are possible with svn, we need to figure out the most acceptable way to tackle the enum issues in doom and mpegplayer |
| 01:25:31 | kugel | replace -1 with an actual enum member seems most sensible to me |
| 01:25:51 | Blue_Dude | Mostly it's a pause issue, but that also takes into account "pauses" such as seeks. |
| 01:26:41 | Llorean | What's the problem with seeks beyond "no voice during the seeking"? |
| 01:27:18 | Blue_Dude | I wonder how much audio is internally buffered in the hardware? Meaning that after it's read by the hardware, what's the latency until it's played? |
| 01:27:20 | kugel | " If you stop playback, then the voice clip that has already been buffered is lost." doesn't seem like a problem to me. How many clips are buffered at a time? More than 1? |
| 01:27:48 | kugel | "And when playback resumes, any voice or effects that were already mixed into the buffer will play." - can't that be fixed without dealing with the destrictiveness? |
| 01:27:55 | Blue_Dude | kugel: A stop cuts off voice playback mid-syllable. |
| 01:27:56 | kugel | destructiveness* |
| 01:28:23 | kugel | Blue_Dude: I understand that, and I don't think it's a big deal |
| 01:28:26 | Blue_Dude | Only if you resume by going back to the codec and having it decode again. |
| 01:28:41 | kugel | it could even be wanted actually |
| 01:28:43 | Blue_Dude | IOW, a resume from stop, not a resume from pause. |
| 01:29:56 | Blue_Dude | Llorean: none as far as I know. |
| 01:30:34 | Llorean | I think losing unplayed voice during stopping isn't too bad, but the issues relating to Pause are a real problem. |
| 01:30:44 | Blue_Dude | In the back of my mind though, I'm thinking about event driven sound effects. Why not play a short clip for button presses, ff/rew, etc? |
| 01:30:56 | Blue_Dude | Agreed. |
| 01:31:15 | Llorean | Isn't there keypress sounds as an option already? |
| 01:31:32 | Blue_Dude | If you decouple dma operation from codec playback, you can do a lot. |
| 01:32:02 | Blue_Dude | There's a keyclick. That's also handled by direct mixing or the hardware. |
| 01:32:35 | Blue_Dude | I'd like to make pcmbuf_beep mix non-destructively also. |
| 01:32:58 | Blue_Dude | That's less painful though, almost an afterthought. |
| 01:33:10 | kugel | I fear getting rid of the destructiveness is going to be a performance hit for very little gain |
| 01:33:15 | Unhelpful | kugel: a result of doing that is that switches on variables of the enum type will need to handle that member, either explicitly or with a default, to avoid a warning. even if the switch code can never execute with the -1 flag value set. :/ |
| 01:33:45 | Llorean | kugel: If it's the "best" way to enable voice while playback is paused, the gain is pretty significant. |
| 01:33:46 | Blue_Dude | kugel: I can't figure out another way around the pause problem though. |
| 01:33:49 | | Quit fyrestorm ("Ur skills' fireproof like a wooden panel -- U got feds talking leet on your IRC channel!") |
| 01:34:16 | Llorean | For iPod users especially, who aren't used to the idea that there's a "stop" function, many times they're left somewhat lost by the fact that voice seems to just stop working for them entirely. |
| 01:34:22 | kugel | the pause problem is that, while being paused already, there's no way to have voice right? |
| 01:34:29 | Blue_Dude | Right. |
| 01:34:33 | Llorean | Yes, if playback is paused, voice cannot play. |
| 01:34:37 | kugel | I don't see how you need non-destructiveness for that to fix |
| 01:35:00 | | Join lostlogic [50] (n=lostlogi@rockbox/developer/lostlogic) |
| 01:35:18 | kugel | as I understood, the non-destructiveness is needed to not lose voice in the moment of pausing/stopping |
| 01:36:03 | Blue_Dude | True. But if you unpause during a clip, you lose it again. |
| 01:36:16 | kugel | Unhelpful: is that a problem? |
| 01:36:41 | kugel | Blue_Dude: I still think that this is not a huge problem. |
| 01:37:31 | kugel | even less, since you (naturually) wait for the voice clip to finish before resuming (which could make the voice clip unhearable) |
| 01:37:47 | Blue_Dude | Is it possible to tell the dma to quit reading where it is and go play something else? Or is a chunk committed until its end? |
| 01:38:19 | | Quit Thundercloud (Remote closed the connection) |
| 01:38:36 | Blue_Dude | Codec playback is ducked during voice playback. You should be able to hear it anyway. |
| 01:38:57 | kugel | the big problem is getting voice while pased to work, not having it work in the very moment of pressing a button for pause/resume (which is rather unlikely to ever happen) |
| 01:39:05 | Unhelpful | kugel: testing for cases that can't happen doesn't sound good, to me, for code size *or* readability. |
| 01:39:53 | kugel | another switch case is surely negligible |
| 01:40:04 | kugel | code size isn't really an excuse to not do that |
| 01:40:50 | | Part toffe82 |
| 01:41:06 | Unhelpful | and readability? adding a default: or FLAG_VALUE: case to switches that *actually* already have everything covered? |
| 01:41:10 | Blue_Dude | kugel: that could be fixed by pausing the DMA, reading its current position in the chunk and saving that as a pause resume point. Then if a voice clip needs to play, the dma could actually stop, play the voice clip, and pause again. When unpausing, the dma is pointed to the resume point and voila... |
| 01:41:14 | Blue_Dude | Wow, that works. |
| 01:41:24 | Llorean | In most cases I don't see how someone would pause or resume while voice is playing. |
| 01:41:55 | Llorean | You can't pause outside of the WPS, and resuming playback also requires returning to the WPS generally, and there's no voicing of the WPS so any voice still playing there is probably unnecessary. |
| 01:42:03 | kugel | Unhelpful: they obviously don't have everything covered |
| 01:42:05 | Blue_Dude | It's still going to sound like crap if pausing during a voice clip though. |
| 01:42:33 | kugel | default: /* should never happen */ decreases readability? I disagree |
| 01:44:32 | Blue_Dude | Got to go in a few minutes, my battery is going. |
| 01:45:06 | kugel | Blue_Dude: having that work seems quite unimportant to me, even bad if it comes with a (performance) drawback |
| 01:45:06 | Blue_Dude | kugel: I'll take a look at a smarter pause feature. Thanks for thinking out loud. |
| 01:45:39 | Blue_Dude | Yeah, it's just going to be a little clunky. |

| 04:17:04 | Unhelpful | i filed a bug report for the section offset bug against binutils 2.19pre but was never able to produce a small test case, preferably one C file and one linker script, to demo the bug, so it's not *too* surprising that they've done nothing at all. :/ |

| 04:19:25 | Unhelpful | one of the "always false" warnings in doom was for a loop exit condition. that really should be promoted to an error if there's no break in the loop :/ |

| 04:23:51 | Unhelpful | i've not found the binutils bug yet, but here's the vorbis.map that i pastebinned a while ago: http://www.pastie.org/686145 |
| 04:24:51 | Unhelpful | compare the address at which iramcopy is set with the load address of .iram - these are *supposed* to be the same, and are if the end of the previous section happens to align the right way. |

| 04:26:07 | kkurbjun | oh interesting |
| 04:26:09 | cowgarden | wheee!!!!11ELEVEN |
| 04:26:13 | Unhelpful | here's my poor bug report: http://sourceware.org/bugzilla/show_bug.cgi?id=10409 |
| 04:26:34 | cowgarden | My Iaudio7 broke so I had to buy a D2, now I'm in the boat! |
| 04:26:37 | kkurbjun | it looks like it is using the unaligned end of the last section |
| 04:27:33 | kkurbjun | does .ncdata actually contain anything? what is that section used for? |
| 04:27:43 | Unhelpful | kkurbjun: yes, but sometimes it gets it right. the bizarre thing is that the .iram load address is assigned directly from iramcopy, not calculated separately. |
| 04:28:23 | Unhelpful | so it's a matter of val1 = expr (works), val2 = val1 (fails). wtf? ;) |
| 04:28:55 | kkurbjun | :) |
| 04:32:12 | Unhelpful | .ncdata is for non-cacheable data. it's used in core for the tick counter on multicore targets, and i don't recall what else. no codecs or plugins use it, but they certainly could... |
| 04:32:29 | cowgarden | where do I download plugins like rockboy? |
| 04:32:45 | kkurbjun | cowgarden: they are all included in the rockbox.zip |
| 04:32:50 | kkurbjun | the main download |
| 04:33:05 | cowgarden | all? ok I'll check , thx :) must have overseen rockboy |
| 04:33:09 | cowgarden | overlooked |
| 04:33:49 | kkurbjun | Unhelpful: does the bug just happen ot occur around ncdata.. I mean if you mode that to a different part of the linker script does it have a psitive effect? |
| 04:34:24 | kkurbjun | cowgarden: you won't see it in the games list, you just select the .gb file in the file browser you want to play and it will start up rockboy. |
| 04:34:34 | cowgarden | ah, I remeber :) |
| 04:34:47 | Unhelpful | kkurbjun: removing .ncdata works, as do a few other tricks i tried. some things you might *think* would work don't. |
| 04:38:10 | kkurbjun | hmm, it looks like it happened around .ncbss too in that pastebin link you had |
| 04:38:39 | kkurbjun | Would this be an issue with 0 size sections? |
| 04:39:43 | Unhelpful | kkurbjun: i suspect it has something to do with 0-sized sections, yes. i'm rather at a loss as to how to fix. |
| 04:39:58 | Unhelpful | other than work-arounds and hacks, anyway :) |
| 04:40:04 | cowgarden | how to show hidden folders? |
| 04:40:05 | kkurbjun | so the glue sections are 0 size also |
| 04:40:24 | kkurbjun | but they are not manipulating the memory pointer |
| 04:40:28 | Unhelpful | if you assign iramcopy, with the same expression, *inside* .ncdata, it works. |
| 04:41:01 | kkurbjun | it seems that both .ncdata and .ncbss are zero and change the . memory address... |

| 04:44:26 | Unhelpful | no plugin or codec uses them, but amiconn was strongly against removing them, and would rather see the bug fixed upstream or a different work-around used. |
| 04:45:37 | | Quit liar (Client Quit) |
| 04:54:37 | kkurbjun | Unhelpful: does the behavior change if you change the memory pointer before the .ncdata section? I'm not sure if you can do this, but I was thinking . = . + 0x1000000 right before the .ncdata section |
| 04:59:18 | kkurbjun | Unhelpful: we could add an elf loader :-D, then we wouldn't need to have quite such crazy linker scripts |
| 05:00 |

| 07:19:33 | JdGordon | right, this patch is "ready" for commit.... it does cause some minor glitches (which were sort of always there anyway) and they should be simple-ish to fix... but those fixes are heavily dependant on this patch, and I dont want to do both big changes in one commit |

| 08:04:19 | amiconn | Unhelpful: No codec or plugin uses them *atm*, that doesn't mean it will stay this way |

| 08:08:34 | pixelma | about BlueDude's statemen - it's not highlighted lines in general, only scrolling ones (and lines only scroll when they are highlighted and longer than would fit on the display). Besides that I don't understand this statement completely... is it how JdGordon should do? Because the issue has nothing to do with the statusbar but with errors when viewportifiying the USB screen |
| 08:09:17 | JdGordon | yeah, I'm not too happy about the usb screen code.. it has some issues which need fixing |
| 08:09:48 | amiconn | Unhelpful: That fix looks weird. Defining iramcopy twice? And !NOACHE_BASE? |

| 08:09:57 | | Join stoffel [0] (n=quassel@p57B4E8BB.dip.t-dialin.net) |
| 08:11:44 | Unhelpful | amiconn: it's ensured earlier on that NOCACHE_BASE is always defined. essentially the fix defines iramcopy exactly as before if NOCACHE_BASE is 0, but defines it inside .ncdata if NOCACHE_BASE is non-zero |
| 08:12:12 | Unhelpful | i suppose the NOCACHE_BASE-is-zero case could remove any reference to NOCACHE_BASE aside from the #if, and just read as iramcopy = . |
| 08:12:56 | Unhelpful | or maybe you were just suggesting that NOCACHE_BASE == 0 would be more readable? |
| 08:13:13 | pixelma | JdGordon: does the classic_statusbar work on greyscale then? Greyscale uses different viewport parameters too - 4 shades of grey instead of RGB colour... |

| 08:15:13 | amiconn | A comment explaining the trickery is probably a good idea as well |
| 08:15:39 | Unhelpful | indeed! #elif defined(IRAMSIZE) would do the trick, and yes, a comment is an excellent idea :) |
| 08:16:37 | amiconn | pixelma, JdGordon: Does that mean the 'classic' status bar isn't really looking like the real thing on anything but mono? |
| 08:16:40 | Unhelpful | also it looks like IRAMSIZE can be defined as 0... it's probably harmless but should there even be a .iram or iramcopy in that case? |
| 08:16:57 | JdGordon | amiconn: ? |

| 08:32:08 | JdGordon | the charging animation is a nice addition... but an icon showing its charging does the same |
| 08:32:25 | amiconn | If the skin stuff doesn't allow to have a charging animation, it looks to me like a step back instead of forward |
| 08:32:40 | amiconn | An extra icon needs extra space |
| 08:33:20 | amiconn | ...and is less intuitive. All mobile devices I've seen so far indicate charging by means of a charging animation |
| 08:34:19 | amiconn | (although they're often showing less useful information that the rockbox charging animation) |

| 08:46:11 | JdGordon | sure you can get current level and charing yes/no |
| 08:46:32 | JdGordon | you cant get it precise, but maybe we add a new tag for that |

| 08:51:27 | JdGordon | the icon goes there |
| 08:52:28 | pixelma | the gap is probably because your version is wrong (and not as fine grained as the classic) and why would it need a different icon? |
| 08:53:12 | Unhelpful | hrm, i assume that if adding an arm-eabi toolchain target to rockboxdev.sh requires a new gcc patch (and it does) that that can also be checked in via svn? |

| 09:03:04 | pixelma | charger icon is already possible, USB power not yet but should be added (JdGordon said earlier that it is probably quite easy, my question is if it should use a different tag or reuse the charging on (depends on if there are targets that have both not either or) |
| 09:03:42 | pixelma | and charging is already indicated |
| 09:04:22 | amiconn | JdGordon: No, I didn't try that patch yet. I fail to see why I should try a patch that isn't feature complete, adds nothing of value to me, but in turn removes features I'm relying on |
| 09:04:45 | JdGordon | because its being forced on you is a pretty good reason I tihnk |

| 09:06:08 | amiconn | No, that would be a good reason to either stop the force, or working around it |
| 09:07:57 | pixelma | as I said, I'll work on getting the sbs as close to the original as possible currently (and there won't be missing much) |

| 09:14:12 | amiconn | I'm not against the skin engine as such, as it seems there are people interested in it. But what I absolutely don't like is that you're obviously thinking that it is okay to take away features which *you* think are not important |
| 09:15:10 | JdGordon | meh, if it was important at all to the themer community then there would have been a request ages ago |
| 09:16:15 | JdGordon | the loss of the animation is tiny because the exact same info can be got with the charge % and "charign?" tags |
| 09:16:38 | JdGordon | but anyway.. there are so many more ACTUAL SBS BUGS that the fact you want to leave because of this one boggles my mind |
| 09:17:06 | JdGordon | and 90% of those bugs will disappear once this is in and the follow up patch is in |
| 09:17:45 | * | amiconn would throw out most of this skinning stuff in case of a fork, but would actually prefer to avoid going that route |

| 09:19:12 | pixelma | JdGordon: charge % ? I only know of current level % (and the conditional) |
| 09:19:37 | JdGordon | isnt charge level the percent? |
| 09:19:43 | pixelma | and charging yes/no - which probably can be combined in a way to make the animation work |

| 09:20:52 | JdGordon | (11:26:53 PM) JdGordon: it would probably have to be done with some conditional viewport magic and sublines |
| 09:21:52 | n1s | JdGordon: i don't care about themes that much but i understand amiconns point, |
| 09:21:59 | pixelma | why would I need conditional viewports there? |
| 09:22:38 | JdGordon | just saying I said it was possible an hour ago.. that was my initial answer how to do it |
| 09:23:13 | n1s | (sigh) ... i usually don't check patches i don't have any big interest in but then if they change aomething i do use i usually dont' find out untill they are in because the people interested in that patch didn't care about this other feature |
| 09:23:19 | | Join Thundercloud [0] (i=thunderc@persistence.flat.devzero.co.uk) |
| 09:24:57 | JdGordon | (sigh and yawn) the feature is a silly little animation, which can be duplicated, which isnt a core feature, and most people will have disabled anyway... its not like I've gone and removed voice or something |
| 09:26:28 | AlexP | JdGordon: I agree that for me it doesn't matter, but I don't think anyone should presume to know what is important for others |
| 09:27:04 | n1s | JdGordon: i don't mean this as criticism agianst you but it seems to be a common problem of larger patches that do a lot of changes, the people interested in the core of the patch see the other things the pach does (for whatever reason) as unimportant and the people who do care abotu these unimportant changes don't know about them untill patches go in |
| 09:27:36 | pixelma | I wonder where you take the knowledge from that most people will have disabled the classic statusbar, on small screen targets it's still quite nice and at the start it should be the same. As I said earlier (and even in the commit) I'll work on it |
| 09:28:41 | pixelma | during the weekend, got to work now actually... |
| 09:29:23 | JdGordon | my seemingly briliant reasoning is.. how many people are using the inbuilt wps?... and before anyone can refute that.. im going to bed.. for real this time |
| 09:29:43 | AlexP | That matters, but isn't the be all and end all |
| 09:29:50 | pixelma | WPS and statusbar are two different things |
| 09:30:14 | JdGordon | not any more |
| 09:30:19 | JdGordon | thats the whole point of this |
| 09:33:33 | pixelma | huh? |
| 09:33:59 | pixelma | I thought the point of this was to get rid of the built-in thing |
| 09:34:07 | JdGordon | the line between the wps and the sbs and the theme and the skin is alll getting very blurry |
| 09:34:35 | pixelma | I won't be able to chose statusbar and WPS independently from each other? |
| 09:34:55 | JdGordon | course ytou will |
| 09:36:05 | pixelma | so? Then there should be the classic_statusbar.sbs used as default as long as there is no cabbiev2 replacement for it yet (or other default theme if there ever will be one) |
| 09:36:26 | pixelma | and then it is still two different things |
| 09:36:34 | JdGordon | and if everyone was happy with cabbie there would be no need for themes.rb.org |
| 09:36:54 | JdGordon | if the problem is there is no skin tag to do this then file the bug... |
| 09:37:30 | JdGordon | if the problem is the quick reimplementation I did isnt good enough.. then you (being anyone...) know what to do |

| 13:43:40 | cowgarden | hi, as the D2s touchscreen seems to be working really good, how hard is it to write plugins like the exploding/expanding pixel thing? I'd really like ot have a piano |
| 13:47:56 | gevaerts | cowgarden: have you looked at the source? |
| 13:48:21 | cowgarden | gevaerts, no, I never programmed C or anything :) I just know a bit java and actionscript |
| 13:49:18 | cowgarden | but I guess it should be quite easy to extract and modify what I need. Is multiple sound output supported? |
| 13:49:54 | cowgarden | I'd just have to change the click to button areas and assign a soundevent somehow I guess |
| 13:50:36 | cowgarden | and since there is allready a collision system I could simply take that (that way drag might be supported to for those keyboard shwooshes :) |
| 13:50:41 | gevaerts | cowgarden: well, most (or all?) current plugins are written in C, but you can write them in lua these days |
| 13:51:08 | cowgarden | when all are C I'd stay with C to be able to C&P |
| 13:51:37 | gevaerts | you also need some in P then :) |
| 13:52:45 | cowgarden | :) |
| 13:52:59 | cowgarden | are multiple sounds at the same time possible? |
| 13:53:04 | gevaerts | There's no sound mixing though. Rockbox is still primarily an audio player. Someone (Blue_Dude) is working on this, but I don't know if that work will be general enough for this sort of thing. The primary purpose is to be able to mix in voice clips and key clicks with the normal audio stream |
| 13:53:48 | cowgarden | ah, ok, well I was pleased with some 6bit single tone sound :) I just need something responsive to check out some melodies |
| 13:54:06 | * | gevaerts adds a note to the effect that he isn't a sound specialist |
| 13:54:10 | cowgarden | and the original firmware allwas lags when you play sound in flash lite |
| 13:54:15 | cowgarden | :) |
| 13:54:18 | gevaerts | You could do your own mixing I uess |
| 13:54:49 | cowgarden | yeah, but that was way to much work, sadly I have a job and a portfolio for the university to finish :) |
| 13:55:41 | cowgarden | are the emulators all ported to rockbox or written specially for it? |
| 14:00 |
| 14:00:43 | Bagder | they are ports |

| 18:46:42 | gevaerts | pamaury: I'll have a go at trying it on my gigabeat S. That runs Windows CE as the OF, so I'd guess it should behave like the MTP specifiers intended |
| 18:47:09 | pamaury | yes |
| 18:50:07 | pamaury | Note that in the extended properties spec, it is written that Windows first send a request with enough size for the header and then by reading the answer sends a second request with the required size. We never know, perhaps the device will need this magic. |

| 22:30:56 | tornvig | holy moly, the dir looks completely f**cked |

| 22:32:41 | funman | perhaps try checking the disk with fdisk/chkdsk.exe first |

| 22:47:09 | Unhelpful | n1s: i think the lua function in question should be void noreturn anyway, shouldn't it? it calls the plugin exit macro... |
| 22:49:23 | p3tur | amiconn: yeah, I've gone back looking at that histogram code after a year or so |
| 22:51:39 | n1s | Unhelpful: didn't look at all |
| 22:53:04 | n1s | Unhelpful: did you see my results from the beast? basically all codecs were unchanged or faster except aac he (only tested the ones we have test files for though) |
| 22:54:31 | Unhelpful | n1s: yes... i have a branch with switchable -O levels for all codecs, and a spreadsheet with times. i'll need to get the beast run and entered now that i have a cable for it again :) |
| 22:55:27 | n1s | Unhelpful: reenabling fstrict-aliasing gave some small speedups too but some warnings in the zxbox plugin |
| 22:55:57 | Unhelpful | n1s: did anything slow down with it? and are the warnings possibly worth fixing? |
| 22:56:05 | Unhelpful | we could also enable it only for codecs :) |
| 22:56:28 | n1s | none of the codecs i tested slowed down |
| 22:57:22 | n1s | i think fixing the warnings is the way to go if anyone can be bothered, it's disabled since 4.0 gives a lot more warnings iirc |
| 22:59:34 | amiconn | Would be interesting to do the same tests on coldfire |

| 23:00:41 | Unhelpful | n1s: type-punning not done via a union would be the usual thing that triggers those warnings, right? |

| 23:15:01 | JdGordon| | I thought I added mono/stereo? :( |
| 23:15:15 | JdGordon| | is samplerate off by one? or way out? |

| 23:54:41 | LambdaCalculus37 | I was looking at the firmware updates for the Gigabeat MEG50JS and the MEG201. |
| 23:54:56 | LambdaCalculus37 | They're both Linux-based firmwares, like the Gigabeat F. |
| 23:55:14 | LambdaCalculus37 | So I was thinking... we might be able to get custom code loaded onto each of those. |
| 23:55:30 | toffe82 | you can try :) |
| 23:55:40 | LambdaCalculus37 | I certainly would like to. :) |
