| 00:03:24 | CIA-5 | New commit by pixelma (r25692): Fix broken Iaudio M3 manual and missing buttons in the M:Robe 100 manual, caused by the same weirdness of tex: breaking a long opt list needs escaping ... |

| 00:33:01 | b0hoon | so it looks like after my last commits... |
| 00:34:03 | b0hoon | pixelma: but it builded for me locally for 5 different targets |
| 00:35:21 | pixelma | yeah for me too, just the M3 manual didn't build of the ones I tried. It's still weird, we'll see what happens tomorrow |
| 00:35:49 | b0hoon | pixelma: i wasn't aware of this, should i change the way of breaking the lines or wait? |

| 00:37:07 | | Quit phanboy4 (Ping timeout: 265 seconds) |
| 00:37:26 | pixelma | I think I caught all the problematic ones. It's most important if you break \opt{pad,pad,pad,pad} |
| 00:41:22 | b0hoon | ok, i'll pay more attension to this next time... |
| 00:41:28 | pixelma | you'll sometimes see the % (actually a comment that helps "commenting out" the linebrak) at the end of \opt{bla}{blub} too because tex *sometimes* adds a space for the targets where this is not true. Then you'll sometimes see more than one space in the resulting PDF for all targets that are not included. Sometimes it works correctly though and I didn't find a pattern yet |
| 00:43:10 | b0hoon | yes. i was wondering what for it is. |

| 02:21:48 | gusto | so i read that you have support for 2nd generation of ipod nano, i have the 3rd ipod nano and i am now using linux and have problems w/ synchronizing, the files are there but ipod doesnt know them any more |
| 02:22:27 | gusto | i think staying w/ this firmware that needs to be indexed in order to know whats on it isnt the way to go |
| 02:23:32 | gusto | what are the differences between 2nd and 3rd gen of ipod nano? so do you expect to take a long time till support of the 3rd gen ipod nano as well? |
| 02:25:35 | gusto | will i be able then to just copy some files over and be able to play it w/o any sync or special sw? |
| 02:26:07 | gusto | i mean just to mount the dev and copy some mp3s there and play it there |

| 03:47:40 | Unhelpful | it doesn't have to, if you get it to save some runtime ;) |
| 03:48:21 | Unhelpful | i believe auto voltage scaling can be enabled separately... so we could just enable auto voltage and tweak frequency manually. |
| 03:48:51 | Unhelpful | and somebody else must've told you some of it because it's news to me that we're nearly at minimum voltage at 264MHz |
| 03:49:43 | hobbs | Unhelpful: patch from jethead71 from a week or so ago, seeing it in the changelog was what got me thinking |
| 03:49:56 | | Quit adnyxo (Ping timeout: 245 seconds) |
| 03:50:00 | hobbs | dropped it down from whatever unreasonable thing it boots up with (1.6 or 1.65?) to 1.35 |
| 03:51:07 | hobbs | but I agree, auto-voltage and manual CPU would be a good trick |
| 03:54:13 | n1s | Unhelpful: i think it's near the minimum for that freq |
| 03:54:37 | n1s | lower freq could use even lower voltage IIUC |
| 03:56:29 | n1s | gusto: Ports are done by interested developers, and noone seems to be working on the nano3g at the moment, so sending someone your ipod might work if you get them interested in the port but the effort will likely take a long time |
| 03:58:06 | Llorean | I thought jhMikeS said that what we're setting it to is good for up to 399mhz still |
| 03:58:33 | n1s | hobbs: have you measured any runtime differences? |

| 04:00:26 | hobbs | n1s: I did a run last night, at 132MHz & 1.25V, runtime was 5h10m, but I didn't do a baseline run ;) |

| 04:06:44 | n1s | mine was used too |
| 04:06:50 | hobbs | I think a baseline run would be just as bad |

| 04:08:41 | | Join anewuser [0] (anewuser@unaffiliated/anewuser) |
| 04:09:13 | gusto | n1s, and does it sound promising? i mean, can i remove the apple firmware after completely and use like described on the site (drag and drop files and play on the move)? |
| 04:10:22 | n1s | if rockbox is ported, you can drag and drop like to any other usb mass storage device |
| 04:10:34 | gusto | ok |
| 04:10:41 | gusto | and what about the apple FW? |
| 04:10:45 | n1s | if you cna get rid of the original firmware completely is a detail of the port |
| 04:10:57 | gusto | that means? |
| 04:11:15 | RadicalR | Basically, the FW becomes optional. |
| 04:11:18 | n1s | so i can't tell you that now, it depends on how the bootloader etc is designed |
| 04:11:25 | RadicalR | That too. |
| 04:11:35 | RadicalR | However, given the pattern of the Nano2g |
| 04:11:53 | n1s | some of our ports have optional dualboot with the OF, some mandatory and some have only single boot |
| 04:11:53 | RadicalR | I think it's safe to say that it'll probably follow suit. |
| 04:12:08 | n1s | yes, probably |
| 04:12:48 | gusto | and on the nano2g you can get rid of the original fw completely? |
| 04:14:36 | RadicalR | Yes, I just keep it on just in case. |
| 04:14:49 | RadicalR | Well, hold on. Let me double check that. |
| 04:14:59 | RadicalR | It goes to the iLoader |
| 04:15:06 | RadicalR | which allows you to pick what you want to boot. |

| 04:15:36 | gusto | so you can delete the first partition where the fw is then, right? |
| 04:16:30 | gusto | and other thing that am interested in pretty much about this topic is what filesystems can you use then? only FAT32 or also ext2 and other? |
| 04:16:52 | n1s | only fat |
| 04:16:57 | RadicalR | Nix on the first one, and rockbox can only read fat |
| 04:16:59 | RadicalR | yeah |
| 04:17:23 | gusto | ok |
| 04:17:52 | gusto | is there a practical reason, or is it just because there is not enough ppl to write code for it? |
| 04:18:54 | scorche | rockbox supports FAT32 as well... |
| 04:19:05 | | Quit Rob2222 (Ping timeout: 265 seconds) |
| 04:19:17 | scorche | gusto: the reasoning is mentioned here: http://www.rockbox.org/wiki/NoDo |
| 04:19:26 | gusto | because i think on such big storages like nano3g has with 8 GB and newer ones have even more a better FS would show up |
| 04:19:52 | scorche | it isnt about "better"....it is about "compatibility" |
| 04:21:35 | gusto | ah on that site the reason is, because these devices are too weak, have less RAM and other ressourcen, maybe that isnt true for modern ones any more, or will not be |
| 04:21:50 | gusto | yes, compatibility as well |
| 04:22:12 | gusto | but not everybody cares about compatibility, the oroginal firmware cares the less |
| 04:23:00 | scorche | ram is always a major concern...the more RAM we have, the more audio buffer can fit into there...the more audio buffer, the less we have to spin up or access the disk/storage...the less we have to access, the more battery life... |
| 04:23:13 | gusto | forcin ppl to use itunes to synchronize their ipod isnt exactly copmatibility improving |
| 04:23:20 | scorche | so? |
| 04:23:31 | gusto | ok |
| 04:23:50 | gusto | i understand that |
| 04:24:38 | gusto | is on routers the same |
| 04:25:05 | gusto | the more free ram you have, the more nat connections you can route through |
| 04:30:16 | n1s | there also is not a big gain in a "better" fs for most people, as fat* works pretty well |
| 04:32:12 | Llorean | There's really not a very strong reason for moving them to more 'advanced' filesystems anyway. Most of the better features don't relate to the use of it as a portable music player, while FAT32 as a filesystem is pretty much understood by any modern host computer making Rockbox as a UMS device pretty much universally compatible (or as close as you really can be) |

The one manual commit yesterday fixed breakage that only affected the M3 manual, yesterday all manuals "before" the M3 one in the table existed (including the D2), the M3 and everything behind it showed the previous day's manual. This is very different to what usually happened, so while I'm glad it's fixed I'm also curious what exactly happened |
| 07:23:07 | saratogalab | RandomInsano: I think for now all that matters is that you get the basic arm instruction set right, so that should be fine |

| 08:04:36 | pixelma | I would also prefer it if it's not used anymore because you won't get semi-broken manuals but then the script would need to be a bit more clever |

| 12:33:21 | wodz | jhMikeS: I still observe the delay |
| 12:36:00 | n1s | kugel: hmm, yeah, that might be simpler and more elegant, just adding it as a separate kind of build for each target |

| 12:42:45 | hobbs | what a coincidence ;) |
| 12:42:47 | jhMikeS | hobbs: throught the DVFS system or straight register setting? |
| 12:42:57 | hobbs | the latter |
| 12:45:11 | jhMikeS | I've got voltage scaling, confirmed at the test points by a multimeter. The DPTC, there's latency issues with updating regulator settings. I may commit without that part enabled which would fix it at 1.6V for 528MHz and 1.35V for lower frequencies. |

| 12:46:10 | wodz | jhMikeS: Play button is plain GPIO in MPIO. I might change buttons mapping play->select and comment out whole ADC stuff. This way we can eliminate (or confirm) that problem origin is ADC interrupt |
| 12:46:29 | hobbs | jhMikeS: what range of speeds? |
| 12:47:50 | jhMikeS | hobbs: 528, 264, 132, divider only. There is a bug with PLL switching, fixed in r2.0 that forces DVFS to reset the PLL. Perhaps because audio uses the USBPLL, 399 may be workable since that requires using SRPLL. |
| 12:48:52 | hobbs | gotcha |
| 12:49:53 | hobbs | what about dropping the PLL once at boot and using 66-264? |
| 12:50:33 | hobbs | that's essentially where I've ended up with my manual switching |

| 12:54:38 | jhMikeS | 264 won't always cut it for everything. the automatic switch works pretty well and is basically delay-free. we could divide further for 66, but there's other warnings in the errata manual about that. Also, changing PLL changes the SDMA core frequency. |
| 12:55:46 | jhMikeS | of course, the issues are clocking-relative issues, not absolute frequency ones |
| 12:57:19 | hobbs | yeah, I didn't have luck with 528/8 = 66, but I did with 264/4 = 66. And... well, let's say I haven't run into the stuff that needs more than 264 yet. |
| 13:00 |
| 13:00:10 | wodz | jhMikeS: I commented out whole stuff related to ADC and this doesn't remove delay between selecting menu item and entering that menu item |
| 13:00:42 | jhMikeS | hobbs: 528/8=66 will set it to CPU=AHB, which is what the bug is about (iirc). amiconn uses it at 528 with APE. |
| 13:03:10 | hobbs | bleh ;) |
| 13:03:38 | hobbs | oh well, always possible that 66 is no big win I suppose |
| 13:03:43 | jhMikeS | at least with the DVFS you just set PMIC pins to select a different reg. setting. no SPI writes are needed. |
| 13:05:33 | jhMikeS | it benefits from voltage reduction more than frequency. I tested at 528 and 264 at 1.6V and got the same batt life. in both cases. simply changing F seems to just make it take longer/short roughtly in proportion before reaching an idle state and everything's been done to keep the ARM core as idle as possible. |
| 13:07:29 | * | jhMikeS , besides complaints about the S with OF, noticed people not being too impressed with Zune battery life either, with a 800mAh batt no less. |

| 13:16:40 | jhMikeS | n1s: I haven't seen anything saying it should operate less than 1.35V, ever, despite the datasheet saying the min is 1.22V (that low definitely doesn't work :). |
| 13:17:28 | jhMikeS | freescales BSP never sets it below 1.35V, unless it's rev2, but S seems to be rev 1.15 all around |
| 13:17:40 | | Quit shaggy-h (Ping timeout: 240 seconds) |
| 13:17:57 | n1s | ah, so there would be little to no gain in going lower then |
| 13:19:00 | hobbs | now you're making me think my voltage setting isn't |
| 13:19:07 | jhMikeS | n1s: Perhaps it could go a touch lower running so slowly. FS never does it though. |
| 13:20:00 | n1s | jhMikeS: do you know what the OF does? |
| 13:20:13 | jhMikeS | hobbs: only 528MHz (aka. "turbo" and "overdrive") needs DPTC to find the minimum. <= 400MHz only requires 1.35V. |
| 13:21:01 | hobbs | right, but I'm running lower. Unless I'm not because I did something wrong there |
| 13:23:01 | jhMikeS | n1s: It leaves SW1ADVS set at 1.4V. I haven't tracked that part down in the driver. It's sort of a mess to wade throught. I'll try to find out. |
| 13:23:19 | pixelma | jhMikeS: about your repeat question. To me it doesn't sound like it has to do with repeat, more like playlist settings. Did you check your "recursively insert directory" settings or maybe you had auto-change directory set before or something? |
| 13:23:53 | hobbs | I suppose I can try changing all the values to 0.9V and make sure I get a hang. That should be fairly harmless ;) |
| 13:24:04 | jhMikeS | pixelma: I have auto-change set for sure. I'll check that other setting but I never touched it myself. |

| 14:00:43 | wodz | I can navigate with buttons so I guess button events are passed to the queue |
| 14:01:22 | jhMikeS | wodz: but, the delay. I thought you couldn't navigate. |

| 14:01:45 | wodz | yes navigating is weird but possible |
| 14:02:22 | jhMikeS | but every single press should post a message, but maybe they're not and the reading is shoddy? |
| 14:02:33 | kugel | up and down works fine, only selecting menu items doesn't? |

| 14:04:46 | wodz | if I conduct the experiment like this: 1)select item 2) force break in gdb 3) call lcd_update() in gdb I see what should be displayed |
| 14:05:16 | wodz | so button is posted, action is taken but main thread is blocked and lcd_update() is postponed |
| 14:05:45 | jhMikeS | wodz: the menu got drawn in the framebuffer but lcd_update didn't get called? |
| 14:05:58 | wodz | yes |
| 14:06:35 | jhMikeS | doesn't sound like ints and threads then :\ |
| 14:08:10 | jhMikeS | did lcd_update not get called or did it just not update the display? I would think it's destined to call that and will reach it before blocking again. |

| 15:40:24 | Torne | i fixed the beast tone controls the other day :) |
| 15:40:24 | jhMikeS | Torne: software EQ |
| 15:40:30 | Torne | ah |
| 15:40:45 | jhMikeS | it sounds like wrapping noise, but not so severe |
| 15:40:56 | hobbs | jhMikeS: does letting the GPT count during WFI use more power or what? Because timing is so much more consistent with it on |
| 15:41:10 | jhMikeS | perhaps just one band or something, and precut has no effect on getting rid of it |
| 15:41:16 | Torne | jhMikeS: btw, my housemate is interested in working out how to get rockbox to use the beast's DAC's EQ directly |
| 15:41:33 | Torne | i suggested he should probably come on irc and chat to people |
| 15:41:48 | Torne | since it's mostly a UI issue, if i understand correctly |
| 15:42:04 | Torne | (hardware EQs being similar, but not identical, to each other or our software EQ) |
| 15:42:10 | jhMikeS | hobbs: I have no info on that. I just expect it's unneeded and if you're busy waiting, it's not in WFI mode. |
| 15:44:08 | jhMikeS | Torne: Personally, I'd say have a "hardware EQ". Llorean was objecting saying such a thing was confusing. The best compromise I could think up was having 5 "tone controls". Really, it was always an interface thing more than a problem to make it work. I don't care to use them half-assed as bass and treble. We should use that EQ. |
| 15:45:18 | jhMikeS | If we don't we're just jailing the HW a bit and I thought we were supposed to do the opposite of that :) |
| 15:45:24 | Torne | yah |
| 15:45:35 | Torne | if someone did the effort to use them as bass and treble, we might as well have it, though, no? |
| 15:45:45 | jhMikeS | even the gain limiter could be hardware |

| 17:42:18 | jhMikeS | amiconn: hmmm. it always did that and I only used it for a battery bench since there weren't many files on disk at the time. IIRC think the auto change is in the playback engine in playback.c. |
| 17:43:07 | amiconn | Auto-change makes a new playlist from the next directory if the old one ends. Repeat all causes it to never end... |
| 17:43:52 | amiconn | But then you don't need auto-change for battery bench. Just let it repeat one folder... |

| 19:36:45 | n1s | indeed |
| 19:36:57 | n1s | lots of esotgeric options we do have |
| 19:37:03 | n1s | s/g// |
| 19:38:30 | n1s | but i think that if we had an easy way to select multiple dirs for insertion into a playlist, and made playing a file equivalent to inserting that dir into a playlist we could drop ADC and the whole special handling of dir playlists |

| 19:43:21 | jhMikeS | I don't even think we have multiple-selection lists and I'd love that for managing files on the player when away from any other means. |
| 19:45:05 | n1s | no, we don't, it's a feature i would love too |
| 19:45:16 | Llorean | n1s: The thing is, if you click on a file, and expect playback to continue through the folder, some people can (quite reasonable) expect new additions to the folder later (for a podcast folder, for example) to be played. |
| 19:46:36 | n1s | Llorean: but doesn't inserting a dir into a dynamic playlist do that? |
| 19:46:49 | jhMikeS | hmmm...but what would dropping ACD do? I don't mind the option to stick with playing an album from the browser or just play everything I've got. No database init = more RAM too. |
| 19:47:29 | jhMikeS | Llorean: you mean if they move a file into a directory that is already playing through? |
| 19:47:40 | Llorean | n1s: If you "insert" the dir, the playlist is a list of filenames isn't it? It's an unsaved playlist, rather than an index in the folder? |
| 19:47:46 | n1s | jhMikeS: from the times i've looked at playback or playlist code, the dir handling seems to need quite a bit of special cases |
| 19:47:53 | Llorean | If I recall, if you insert a folder with subfolders, you can't bookmark until it's saved. |
| 19:48:41 | Llorean | jhMikeS: Say you click "select" on podcast 3 of 5 in your podcasts folder rather than using "insert" to add it in a playlist. |
| 19:48:52 | Llorean | You get through 3 and part of 4, then stop, then add a podcast six from your computer, then resume. |
| 19:49:05 | Llorean | I'm pretty sure as long as you don't manipulate the playlist playback will eventually reach #6 right? |
| 19:49:15 | jhMikeS | n1s: I can't fathom why it needs 3581 lines of code! of course, what's most of it dealing with? |
| 19:49:29 | Llorean | But if you "insert" the folder instead, you'll insert the 5 individual items, and when a sixth is added to the folder, unless you also insert it, it won't show up in your dynamic playlist |
| 19:50:48 | n1s | Llorean: i'm not sure but IIRC as long as the playlist is unsaved it is "dynamic" and then it just keeps info like inserted dir foo, inserted file bar so if a dir is inserted and later changed and the playlist is not saved, the new contents of the dir will be included too, i might be wrong of course |
| 19:51:41 | Llorean | n1s: I'm not necessarily saying the change would be bad, just unexpected for some. |
| 19:51:51 | n1s | i think this is the cause of the "deleting a file in the dynamic pl will cause resume to pick the wrong file bug" |
| 19:51:59 | Llorean | For example, if we got rid of the directory index based playback entirely, you'd never get the whole "it resumed in a different file I stopped" bug |
| 19:52:34 | n1s | well, apparently we have unexpected behaviour either way :) |
| 19:52:42 | Llorean | n1s: I'm pretty sure those are playlists created by simply pressing 'select' on a file, rather than using "insert" |
| 19:52:51 | n1s | might be |

| 19:53:08 | jhMikeS | Llorean: something tells me you shouldn't index where you don't wholly control the contents |
| 19:53:18 | Llorean | jhMikeS: Sadly, we already do. |
| 19:53:41 | Llorean | And it does allow the nice behaviour of being able to have a playlist that continues into a file that wasn't there before, but that's about the only positive I think. |
| 19:53:46 | n1s | Llorean: anyway, multi select is something i would really like |
| 19:54:08 | Llorean | Me too |
| 19:54:56 | Llorean | I'd also like to split "right" and "select" one day, so that one could actually be "invoke what is highlighted" and the other could be either "insert" or "select" or some other list action. |
| 19:56:41 | pixelma | the index way is also a lot faster I believe (I always thought this is the reason) |
| 19:56:59 | | Quit xiainx (Quit: Good Bye) |
| 19:57:44 | Llorean | Yes, an "insert" takes a bit for it to iterate through and insert all the files |
| 19:58:13 | Llorean | But couldn't playback start based on the index when you 'select' a file (since at that one point, we know it's constant) then the iteration to populate the playlist happen after? |
| 20:00 |
| 20:00:37 | pixelma | hmm... it could also be from the time resume info and other settings where stored in a hidden sector and space to store something was quite restricted? |
| 20:00:49 | pixelma | could be I'm confusing things though |
| 20:01:05 | n1s | Llorean: yeah, it could, this would also help the case where people select a file in the database from a view of all their files, which causes al those files to be inserted into the pl before playback starts |
| 20:01:45 | n1s | i think we would need a pl worker thread then though |

| 20:49:25 | jhMikeS | why they have DPTC tables for frequencies where DTPC isn't necessary is a bit perplexing. one driver version only has tables for overdrive, has checks for imx31 rev 1, sets voltages to 1.25V for dvs yet rev 1 can't use that, supposedly, according to the other drivers. there's even another version I found online. |
| 20:53:33 | jhMikeS | then there's that SDMA stuff, where it has checks in the BSP for rev 1.00, and code! but elsewhere it says it was never a production part. nonetheless, that was much easier to sort out and I can probably remove that overhead from the compiled binary. |
| 20:56:28 | n1s | i hope we can assume all the beasts use the same chip rev? |

| 21:22:27 | TexasRockbox | I did try changing the extention of the video file to .mp3 and that didn't work |
| 21:23:09 | pixelma | you mean that they show up if you set your file view to "Music" |
| 21:23:10 | pixelma | ? |
| 21:23:30 | pixelma | just for clarification, I had to parse the sentence a few times |
| 21:24:55 | TexasRockbox | If I change the extention of the video file the file shows but does not play. If I leave the extention to .mpg the file isn't visible unless I select show files "All" or "All Supported". |
| 21:25:19 | TexasRockbox | What I want to do is show just music and video files only |

| 21:33:04 | new_bee | i own a sandisk clip mp3 player, and wanted to install rockbox on it. but it seems that there is only a version of rockbox in the category "not usable". what does this mean exactly? |

| 21:34:35 | TexasRockbox | The Clip has several versions the original clip, clip V2 and clip+. Work is being done on the clip V2 and clip+ but isn't fully supported. |
| 21:34:51 | Strife89 | Hmm, can I interest someone in looking at this patch? http://www.rockbox.org/tracker/task/5111 |

| 21:40:46 | new_bee | i already looked at it but didnt found any information of what i can do with the nonusable version and what not. i think i have a sansadisk clip+ |
| 21:41:05 | amiconn | Llorean, jhMikeS: The index method is one reason why rockbox' playlist creation is so much faster than e.g. archos' |
| 21:41:44 | jhMikeS | amiconn: I'm not even clear on what that is (as a 'method' per se) |
| 21:42:35 | amiconn | The archos OF had a limit of 999 files per playlist for that reason, and its playlist generation was so slow that early versions even went into idle poweroff before staring to play if you actually tried to add that many files |
| 21:42:38 | TexasRockbox | @new_bee beneath the section Unusuable Ports" there is a link to "status summary of....." |
| 21:42:46 | | Quit pamaury (Quit: Page closed) |
| 21:43:12 | amiconn | Later versions fixed it (the idle poweroff, not the slow speed, by not considering playlist creation as idle) |
| 21:44:45 | amiconn | And the playlist cachectrl thread only exists on swcodec, and for a very different reason than playlist *building* (iirc) |
| 21:45:19 | archivator | Hmm, can we have the first voltage measurement (after boot) taken after the disk has been stopped? I find the low battery level reported kind of annoying. |
| 21:45:49 | jhMikeS | this method doesn't bother with filenames, but directory indexes? |
| 21:45:58 | amiconn | yes |
| 21:46:12 | jhMikeS | amiconn: that was @ me? |
| 21:46:24 | amiconn | yes |
| 21:48:25 | n1s | archivator: if you resume on startup, that could be a few seconds before reading it, and that would be annoying IMO |
| 21:49:33 | archivator | n1s: I *do* resume on startup and I also have the battery level announced (voiced). It's quite startling hearing that I the battery is at 9% and a few moments later when I look it's at 31% :-/ |

| 21:55:35 | pixelma | amiconn: the problem with it which also gets reported sometimes is resuming a different track if one or more tracks get deleted in the meantime |
| 21:55:54 | new_bee | TexasRockbox : thanks againg, i will. i will also read in how to contribute. maybe i can help. i know some c |
| 21:56:44 | amiconn | Well, if you can find a better method while keeping the speed - go ahead |
| 21:56:46 | TexasRockbox | @new_bee Great! Please feel free to contribute, work is ongoing and any help is appreciated |
| 21:57:38 | jhMikeS | n1s: that just it, how to rematch the index, if index method isn't abandoned (and I suspect it won't be so easily). |
| 21:57:44 | n1s | archivator: you could try increasing the delay before first battery reading in powermgmt.c:648 |
| 21:58:16 | amiconn | Imo being slightly off in rare cases (how often do you add/remove stuff from your dap *in the current folder*?) is much better than being slow *every time* |
| 21:58:51 | jhMikeS | we should probably have find voltage reading compensation while spinning, speced for each battery, just like the charging curve |
| 21:58:54 | archivator | n1s: thanks, I'll take a look. |
| 21:58:54 | amiconn | And just storing the filename won't help |
| 21:58:57 | TexasRockbox | Again, is there a way to configure Rockbox via the interface to show both music and video files? If not, where in the code would it be changed to permit the showing and playing of supported video types? |

| 22:00:53 | Llorphone | TexasRockbox: doesn't "supported" include video? |
| 22:01:00 | n1s | i can't remember when i deleted a file and replaced it with one with the same name |
| 22:01:22 | pixelma | I've heard of people storing all their tracks in the root folder and you wont know with e.g. iTunes stored music getting off topic a bit). I'm all for keeping the quickest method and never had a problem with deleted files, just stating why the discussion came up |
| 22:01:34 | n1s | anyway i meant to store the filename in addition to the index so we match index like we do now but then also check the filename |
| 22:01:51 | TexasRockbox | @llorphone yes it does but I use album art in the album subdir and I don't want to see the .jpg |
| 22:02:09 | | Quit Llorphone (Remote host closed the connection) |
| 22:02:15 | n1s | pixelma: people with itunes files are unlikely to use the filebrowser for playing |
| 22:02:18 | amiconn | Overwriting a file with the same name does e.g. happen when editing tags directly on the target's disk |
| 22:02:18 | pixelma | n1s: and what do you do if they filenames don't match? |
| 22:02:24 | n1s | give up |
| 22:02:58 | n1s | amiconn: ok, so it isn't perfect but better than what we have |
| 22:03:09 | pixelma | n1s: resume info will probably stored from the folder name still? |
| 22:03:09 | amiconn | If it's id3v2 and the tag editor has to change the tag's size, that essentially means a copy operation, which can only be done using a tempfile |
| 22:03:25 | TexasRockbox | The idea is just to have only music and video appear |
| 22:03:27 | n1s | the common case for this seems to be people who listen to podcasts and then deletes them |
| 22:03:50 | Strife89 | Is there any work on using the Broadcom chipset in the iPod Videos? |
| 22:04:02 | Strife89 | A patch, for instance? |
| 22:04:12 | amiconn | Well, if you delete old entries while the folder is still playing, things *should* keep working as expected |
| 22:04:24 | n1s | Strife89: not much, someone made the tv out work a bit |
| 22:04:26 | jhMikeS | how's this stuff sorted if it's up to the fat which order the files are found? it seems names have to be dealt with in some way. |
| 22:04:43 | Strife89 | n1s: Ah. |
| 22:05:18 | n1s | amiconn: i think more like listen, stop, connect to computer, add and delete a few podcasts, resume, bang |
| 22:06:27 | amiconn | Never happened to me but then I've never listened to a single podcast on any device other than my computer |
| 22:07:17 | * | amiconn isn't sure how the name -> index assigment actually works |
| 22:07:18 | n1s | sure, it's never happened to me either, but then i don't listen to podcasts |
| 22:07:40 | jhMikeS | me suggests invalidating the playlist after connect |
| 22:07:48 | amiconn | On my computer I've listened to one or two podcasts so far |
| 22:07:55 | amiconn | jhMikeS: eurgh... |

| 22:12:24 | jhMikeS | amiconn: stuff you added manually I take it? obvious rebuilding under the same rules should produce the same list. |
| 22:12:55 | jhMikeS | *assuming nothing changed of course |
| 22:13:02 | amiconn | Yes, but it won't reproduce my current position |
| 22:13:47 | * | amiconn always wonders why people want to change things which are proven to work reasonably well for a long time already |
| 22:14:30 | n1s | it doesn't work well for everyone |
| 22:14:54 | * | jhMikeS refrains from giving some of the many possible retorts to that :P (too political) |
| 22:15:01 | fml | amiconn: then the playlist creation would still be fast, but playlist manipulations were also better detectable |
| 22:15:10 | amiconn | Then change it in a way that doesn't make it worse for those cases where it works well |
| 22:15:51 | amiconn | Those cases are still the majority... and for the podcast case there is a workaround |
| 22:16:12 | n1s | i think storing the filename of the currently playing song is a good compromise, and give up if the name and index doesn't match |
| 22:16:12 | n1s | but no, i don't care enough to do anything about it |
| 22:16:20 | amiconn | Insert the podcasts individually instead of playing the first track in the folder |
| 22:17:10 | n1s | also if people think about the problem, maybe someone will come up with a way that is both fst and more reliable |
| 22:17:16 | amiconn | Te resulting list will load slower (probably not noticeably provided there aren't too many podcasts in the folder), but position will always be correct |
| 22:17:28 | jhMikeS | amiconn: what do you mean "your current position"? I wouldn't think it would change if a playlist were a perfect duplicate. |
| 22:17:29 | fml | n1s: the background thread could e.g. ensure that two files around the current position have the names stored so that small shifts are recoverable |
| 22:17:51 | amiconn | jhMikeS: My playing postion... |
| 22:18:07 | amiconn | If you invalidate the list and I have to re-create it, it would play from the beginning |
| 22:18:30 | amiconn | The background thread does not exist on hwcodec |
| 22:18:50 | n1s | fml, sure, it would need to be a compromise |
| 22:19:16 | archivator | domonoky, bluebroth3r: what's the status of the concurrency patch? i.e., should I do something more to get it comitted? |
| 22:19:17 | fml | amiconn: how is the DB created on hwcodec? |
| 22:19:21 | archivator | committed* |
| 22:19:31 | n1s | amiconn: that is one thing that would also be easier with a way to multiselect, right now, it's a bit tedious |
| 22:19:38 | jhMikeS | amiconn: why should file and current time index be discarded? I can't think _why_ the playlist couldn't be started from anywhere. ?? |
| 22:19:54 | amiconn | Multiselect would be nice. Somebody please find enough buttons for that... |
| 22:20:11 | pixelma | jhMikeS: from the middle of the track? |
| 22:20:17 | bluebroth3r | archivator: sorry, didn't have time looking at it the last days (was stuck due to volcano ashes for some days ...) |
| 22:20:26 | domonoky | archivator: i am not sure. i think we said last time, to just wait for after the release. So i think it could go in. |
| 22:20:38 | pixelma | jhMikeS: and do you always remember which track you were at last |
| 22:20:50 | amiconn | jhMikeS: Current playlist and resume position are related. If you invalidate the former, you also invalidate the latter |
| 22:20:52 | jhMikeS | pixelma: yeah, it's just a seek time stored through the playlist functions anyway |
| 22:21:09 | pixelma | but you said that would be discarded? |

| 22:21:43 | amiconn | fml: Umm, using the database thread? |
| 22:22:13 | * | amiconn only updates the db occasionally... mostly for showing pictureflow to someone |
| 22:22:15 | jhMikeS | it calls playlist_update_resume_info(id3); when the audio is stopped |
| 22:23:24 | fml | amiconn: so it's possible to have multiple threads on hwcodec? From you reply I thought it's impossible. But if it's possible we could have another thread (or use an existing one) for updating the playlists (adding file names to the current position and around it) |
| 22:23:27 | pixelma | don't bookmarks still work even when tracks in the folder get deleted? |
| 22:23:29 | jhMikeS | index and offest and tossed inti global_status |
| 22:23:57 | amiconn | fml: Of course it's possible. What I was saying is that the playlist_cachectrl thread doesn't exist on hwcodec |
| 22:24:03 | jhMikeS | s/offest/offset/, s/and/get/, s/inti/into/ |
| 22:24:33 | fml | amiconn: I didn't know it exists on swcodec :-) |
| 22:24:56 | n1s | pixelma: i think they are filename based |
| 22:25:11 | amiconn | Iirc it was introduced to solve a problem with trackchange on swcodec (and that doesn't affect hwcodec, obviously), so it would be a waste to have it on hwcodec |
| 22:25:27 | amiconn | Afaik it has nothing to do with playlist creation |
| 22:26:42 | amiconn | Threading itself dates back to the beginnings of rockbox (without priorities and stuff like that) |
| 22:27:20 | fml | Then I think we could hijack a thread for that. Not every thread is heavily busy all the time. |
| 22:28:13 | amiconn | Hwcodec still has thread priorities disabled, since there is no reason for this so far |
| 22:33:26 | jhMikeS | it's there mainly to ward-off audio breaks during user activity like scrolling which I can't see HWCODEC having an issue with since it just sends MP3 data with an ISR |

| 22:37:27 | n1s | i remember the ipod video being mentioned |
| 22:38:34 | jhMikeS | not sure how it would unless you jump the UI priority. the first scheduler just ran thought all contexts on each context switch. non-runnable threads actually used CPU time when switching tasks. |
| 22:39:34 | jhMikeS | go back in svn just before slasheri's initial change to a genuine blocking scheduler |
| 22:40:46 | jhMikeS | I think amiconn used to measure some 3400 task switches/sec during playback on archos, now it's about 12 per second |
| 22:41:41 | amiconn | Nah, certainly not that many if all threads were sleeping |
| 22:41:59 | domonoky | archivator: i am just trying you latest patch for rbutil, and got some problems: No progress info while voicing and the log contains a line like : "can not create children for parent in different thread". All on Windows and with sapi as voice. |
| 22:42:08 | amiconn | Iirc that was the possible maximum (with the old scheduler) in a yield() test |
| 22:42:11 | jhMikeS | amiconn: you did give me a number in the thousands, I'm sure it's logged somewhere |
| 22:42:21 | jhMikeS | ah |

| 22:43:04 | amiconn | ..per second |
| 22:44:22 | archivator | domonoky: interesting. I'll admit I haven't tested it on windows. |
| 22:44:49 | domonoky | archivator: strangly progress info works for encoding.. maybe its because sapi doesnt run in paralell ? |

| 22:45:39 | archivator | domonoky: yeah, but it's marked as such and thus there should be only one thread. Unless.. are you getting that error from SAPI or from Qt? |

| 23:52:48 | domonoky | archivator: for the log: if i replace the voicescript->waitForReadReady() call in TTSSapi::voice with a loop which waits till i can read a line, the progress info works again, also the error message is gone. But i noticed a new problem: if i abort while voicing rbutil completly hangs up. |
