[00:36] <ubitux> HEADERS-$(CONFIG_OPENCL) += opencl.h [00:36] <ubitux> erm [00:37] <ubitux> this is not supposed to be installed, right? [00:37] <ubitux> or do we? [00:37] <ubitux> we export some opencl api? [00:38] <cone-334> ffmpeg.git 03Clément BSsch 07master:d558e46469e0: lavfi: add two opencl headers to SKIPHEADERS. [01:21] <cone-334> ffmpeg.git 03Clément BSsch 07master:a466c2c470f7: fate: fix filtfmts-test dependency after 9a5924f. [02:16] <cone-334> ffmpeg.git 03Clément BSsch 07master:e881057c982e: fate: add a rule for pixfmts tests. [02:16] <cone-334> ffmpeg.git 03Clément BSsch 07master:1e0a0aafba62: fate: port our pixfmts change to fate-run.sh. [02:16] <cone-334> ffmpeg.git 03Clément BSsch 07master:93aede41ce05: fate: move kerndeint test to the new system. [02:16] <cone-334> ffmpeg.git 03Clément BSsch 07master:45734dea9e03: fate: port remaining filters to new system. [02:16] <cone-334> ffmpeg.git 03Clément BSsch 07master:2609434b45ab: fate: remove forgotten transpose filter results from old system. [02:16] <ubitux> ok now we are good [02:16] <ubitux> ...and i need to fix what i broke :p [02:17] <ubitux> i hope filter=${filter%_*} will work properly (sh/dash looks ok) [02:17] <ubitux> michaelni: was there anything else while i'm still in fate? [02:19] <michaelni> hmm dunno, tests for every decoder, encoder, muxer, demuxer and ffplay [02:20] <ubitux> michaelni: i meant from the fork merge PoV :p [02:20] <ubitux> sorry i'm not motivated to work for days on adding tests :p [02:20] <michaelni> i know and noone is [02:21] <ubitux> :) [02:21] <ubitux> socis! [02:21] <ubitux> :) [02:21] <michaelni> hmm, yes that sounds like a good idea [03:00] <burek> is there any work planned on intel's quick sync (in ffmpeg of course): http://en.wikipedia.org/wiki/Intel_Quick_Sync_Video [03:07] <Compn> do you sample ? [03:07] <Compn> oh nm [03:07] <Compn> newer than atom stuff then ? [03:07] <Compn> or is it the same api as the atom chips ? [08:54] <cone-480> ffmpeg.git 03Diego Biurrun 07master:97c56ad7961e: x86: dsputil: Remove a set of pointless #ifs around function declarations [08:54] <cone-480> ffmpeg.git 03Michael Niedermayer 07master:01a5a3a2e8ac: Merge remote-tracking branch 'qatar/master' [11:14] <durandal_1707> hmm 3 test are disabled or? [11:18] <durandal_1707> ubitux: gifenc is failing on big-endian? [11:18] <michaelni> gif fails due to designb flaw in sidedata, its endian dependant IIRC [11:19] <durandal_1707> ah [11:28] <cehoyos> michaelni: The bug ("blue") that you fixed in xyz is not in Matthias Buercher's original filter: http://www.belle-nuit.com/xyz2rgb-video-filter [11:40] <cone-480> ffmpeg.git 03Paul B Mahol 07master:2bdd434931e1: lavfi/stereo3d: add support for alternating frames input & output format [12:25] <cone-480> ffmpeg.git 03Paul B Mahol 07master:e85f02e3f5e2: fate: add test for telecine filter [12:25] <cone-480> ffmpeg.git 03Paul B Mahol 07master:468ec1714c18: fate: add test for swapuv filter [12:25] <cone-480> ffmpeg.git 03Paul B Mahol 07master:a0adeb1f9f9b: fate: add test for separatefields filter [12:54] <durandal_1707> beastd: could you make art contest to get something like this: [12:54] <beastd> hi durandal_1707 [12:54] <durandal_1707> https://lh6.googleusercontent.com/-UVCROnHgAVw/UWa7bDpj2lI/AAAAAAAAAMk/jtiD… [12:55] <durandal_1707> perhaps even new logo, (zigzag is boring) [12:56] <beastd> durandal_1707: ok. will do. but please give me a few days. you can nag me here daily on IRC though [12:57] <beastd> durandal_1707: You want new art for g+ ? [12:58] <durandal_1707> it does not g+ mentioned in contest [12:58] <durandal_1707> its just different size of logo [12:59] <durandal_1707> but not done wiht -vf scale= [12:59] <beastd> of course not [13:00] <beastd> durandal_1707: ok will make the contest description generic. [13:01] <beastd> see you [13:01] Action: beastd goes AFK [13:42] <cone-480> ffmpeg.git 03Michael Niedermayer 07master:147a45fca4d8: framecrcenc: workaround design flaw in sidedata palette [13:42] <cone-480> ffmpeg.git 03Michael Niedermayer 07master:53efb2fa09c0: gif: Fix little endian specific code [14:20] <durandal_1707> is it possible to set outlink format depending on inlink format? [14:21] <durandal_1707> say input format is 8bit, i want output format to be 8bit to and not 16bit [14:37] <durandal_1707> so the only place one can insert outpads is in filter .init ? [15:10] <durandal_1707> the limitation that its only possible to insert outpads in .init is really bad [15:38] <durandal_1707> is it even possible to fix this without writing another api? [15:44] <durandal_1707> michaelni: i hope you applied with "useless" removed [15:47] <michaelni> durandal_1707, why should i have remvoed it ? [15:48] <michaelni> after all you choose not to remove it when sending the patch :) [15:51] <durandal_1707> if that issue about dynamic pads is resolved it will certainly become more useful [15:57] <durandal_1707> omg, this is ridiculous, renaming filter contexts ... [16:01] <BuxiNess> Well, have a nice Worker day, and don't forget the lily of the valley [16:09] <durandal_1707> instead of doing one filter that extract planes, add several filter that extract single plane (alphaextract is already preset), that gives 6 extra filters, (or even more for > 8 bit) [16:28] <Bor0> what variable in ffplay is used to specify size of buffer for reading videos through http? [16:30] <durandal_1707> -inbuf? [16:31] <Bor0> can't find such variable in ffplay [16:31] <durandal_1707> infbuf [16:32] <Bor0> I'll look into that, thanks [16:51] <Bor0> what's the easiest way to check for "buffering" indicator? [16:52] <durandal_1707> i don't think there is such thing [16:52] <Bor0> could you tell me around which part of ffplay would I look at to implement it? [16:54] <durandal_1707> i can not tell you, because i do not know anything about ffplay [16:55] <durandal_1707> but anyway, why you want that in ffplay? [16:55] <Bor0> I see, okay. I'll look around av_read_frame perhaps. [16:55] <Bor0> I have converted it to libffplay, which then I am embedding it to my browser plugin [16:56] <durandal_1707> ther buffering thing is part of protocol, so its internal in libavformat, and afaik user can not control it [16:56] <Bor0> I only need indicator when the video is buffering, instead of getting frozen frame [16:57] <durandal_1707> i don't think there is such thing, if you want it open feature request on our trac [16:58] <ubitux> durandal_1707: i need to check something for gce, i think i missed something when testing with browsers [16:58] <ubitux> (like a cache issue or something, making me think it worked) [16:58] <durandal_1707> aha..., [17:42] <durandal_1707> ubitux: looks like anto is making changes to allow config_props stuff to be called multiple times between single init/uninit [17:42] <ubitux> possibly live reconfiguration or something [17:45] <durandal_1707> i wonder how i could resolve this dynamic output thing [17:59] <durandal_1707> is nullsrc supposed to return uninitialized data? [18:20] <durandal_1707> is it possible to save each filter output to separate file? [18:36] <michaelni> no but it sounds like such feature could be usefull [18:38] <durandal_1707> i mean filter that have several outputs [18:40] <durandal_1707> ffmpeg -f lavfi -i testsrc -filter_comples split=4 ... [18:40] <durandal_1707> i want that each 4 "streams" are saved in separate file and not "magically" interleaved in single one [18:49] <durandal_1707> got it: ffmpeg -f lavfi -i smptebars,format=yuva444p -filter_complex "extractplanes[y][u][v][a]" -frames 5 -map '[y]' /tmp/y%d.png -frames 5 -map '[u]' /tmp/u%d.png -frames 5 -map '[v]' /tmp/v%d.png -frames 5 -map '[a]' /tmp/a%d.png [22:32] <ubitux> couldn't we make use of openmp in most filters? [22:32] <ubitux> also, how could we that would work with our threading? [23:10] <seanDuncan> I'm trying to use x264's qpfile option through ffmpeg's 'x264opts' option but qpfile doesn't seem to be working from there. is it called something else in ffmpeg? [23:11] <durandal11707> seanDuncan: wrong channel [23:11] <seanDuncan> I oh sorry [23:11] <seanDuncan> #ffmpeg more appropriate? [00:00] --- Wed May 1 2013

[00:59] <Guest1296> When does player i.e youtube or dailymotion player get to know to start video playback ....Is it depending on buffer size or key frames? [01:01] <Guest1296> is that limited to number of frames or just the buffer/time [01:02] <Mavrik> usually it starts immediately as soon as it has minimal amount of data in buffer [01:02] <Mavrik> and enough information to start playing [01:02] <Mavrik> it depends on player really [01:03] <Guest1296> Ok [01:03] <Guest1296> it is different for different players right [01:04] <Guest1296> someone mentioned that when we at least get one key frame ...and player immidiatly start playback [01:05] <Guest1296> i just wanted to confirm from our group is that true [01:06] <Mavrik> Guest1296, also it depends on container and format [01:06] <Mavrik> e.g. if you have an MP4 with MOOV atom at the end it wont play until it downloads whole file :) [01:07] <Guest1296> correct... also inorder to extract/read moov atom even though its in beginning is little bit time consuming [01:09] <Guest1296> Great thanks [02:28] <voidah> hi guys [02:29] <voidah> I'm trying to modify a little thing in x11grab [02:30] <voidah> is there a standard way in other part of ffmpeg to change some config values at runtime? [02:31] <voidah> or a way to check for external event [02:31] <voidah> what I want to do is to disable mouse cursor capture/drawing depending of an external event [04:16] <voidah> hi, I have made a small (hackish..) patch [04:16] <voidah> I would like, if someone want, show it to a ffmpeg developer [11:38] <kornerr> hi [12:14] <zap0> lo [15:00] <ElMarikon> hi guys! I am trying to find out how to set channel names for each output channel... [15:01] <ElMarikon> if the movie allready has the tags as an input file, ffmpeg is able to just copy them, but how to initially set them? [15:01] <ElMarikon> a list of possibilities is shown on: ffmpeg -layouts. [15:02] <ElMarikon> I can set the layout, but not individual channel names... can s.o. help me, plz?! [15:20] <ElMarikon> noone? [15:22] <spaam> channel names ?:O [15:22] <spaam> like channel 1 is called microchip_ and the second is called sacarasc ? [15:23] <spaam> or what do you mean? [15:23] <sacarasc> sacarasc is a silly name. [15:24] <spaam> its hard to say... my friend an i say "that sac-ish dude you know" [15:26] <sacarasc> Hehe. [15:27] <spaam> sacarasc: i dont think we will get an answer from ElMarikon :( [15:37] <nchauvet> Hi, is it legal to redistribute a ffmpeg built (GPLv2) with fdk-aac ? [15:39] <durandal_1707> no [15:45] <ElMarikon> sorry, was gone for a moment... [15:46] <ElMarikon> i am talking about channel names, like L, R, C, LF... [15:47] <ElMarikon> with QT u can assign them for each hannel, ffmpeg can then read theam and give them on to a new target (mov)... [15:47] <ElMarikon> but I need to know, how to initially set them WITHOUT QT... [15:47] <ElMarikon> (because it's slow , closed and unhandy...) [15:48] <ElMarikon> spaam [16:21] <ElMarikon> ...and now they are all gone:-( [16:25] <Peace-> is there a way to speed up a video with ffplay ? [16:32] <watcher13> Hey! I'm trying to capture a video from a Logitech C905 webcam on Raspbian with ffmpeg, but get an error from [video4linux2 @ 0x1371840] Cannot find a proper format for codec_id 0, pix_fmt -1 [16:33] <Peace-> mm [16:33] <watcher13> I wonder, do I have to install libv4l2 or libv4l2-convert manually to get that codec? [16:33] <Fjorgynn> I love [16:36] <Peace-> watcher13: paste all the output with the commad [16:36] <watcher13> avconv version 0.8.6-6:0.8.6-1+rpi1, Copyright (c) 2000-2013 the Libav developers built on Mar 31 2013 13:58:10 with gcc 4.6.3 [video4linux2 @ 0x1371840] Cannot find a proper format for codec_id 0, pix_fmt -1. /dev/video0: Input/output error [16:37] <Peace-> the command ? [16:37] <watcher13> That's all [16:37] <watcher13> Oh, sorry [16:37] <watcher13> avconv -t 5 -f video4linux2 -s 320x240 -r 30 -i /dev/video0 -vcodec mpeg1video out.avi [16:37] <Peace-> :) #avconv [16:38] <Peace-> ups [16:38] <Peace-> there is the other channel for avstuff [16:38] <watcher13> Ok, but ffmpeg output is the same, except by deprecation warning [16:38] <durandal_1707> Peace-: ffplay is simple media player [16:39] <Peace-> durandal_1707: i knew [16:40] <watcher13> Peace: I just wonder, what info you guys can extract from that output: it's absolutely non-verbose. May be I can use some flags to have ffmpeg give more info? [16:41] <relaxed> why mpeg1 in avi? [16:42] <durandal_1707> watcher13: this is channel for ffmpeg from FFmpeg and not from Libav, either try latest ffmpeg or ask help on Libav channel [16:42] <relaxed> it's #libav [16:43] <Peace-> watcher13: well the command it's not write well btw [16:43] <Peace-> at least for what i know [16:46] <ElMarikon> since there is sth going on here, now... my question again: [16:47] <ElMarikon> how do i assign channel names to individual audio channels in eg. a mov file? [16:48] <ElMarikon> ffmpeg -layouts shows the available names, but no command to assign them to channels... [16:48] <ElMarikon> i found out, ffmpeg can pass them through from some other file, like mov to a new file, but how to initially set them [16:48] <ElMarikon> ? [16:49] <ElMarikon> anyone has a clue? [16:49] <ElMarikon> plz!! [16:50] <watcher13> Peace, durandal_1707: ok, but ffmpeg's output is the same, just s/avconv/ffmpeg/gc. What info can I get from ffmpeg and give to you, so that it helps? [16:53] <durandal_1707> watcher13: i told you: the only way you can help yourself is by trying latest version [16:53] <durandal_1707> ElMarikon: you want to remap channels? [17:52] <ElMarikon> durandal_1707: No, #I don't need to remnap. I just need to label them... [17:54] <durandal_1707> label what? [18:03] <spaam> durandal_1707: the channel. so right channel will have R and left channel will have L and so on. [18:05] <durandal_1707> so he have mov with each channel in separate stream? [18:14] <watcher13> Peace, durandal_1707: Thank you. [18:20] <ElMarikon> well--- maybe separate streams maybe in one stream... [18:20] <ElMarikon> my point is, i have to assign a label for every channel. [18:21] <durandal_1707> in what way? via metadata or? [18:22] <ElMarikon> well... how ever... just need to tell ffmpeg, that my 1st channel is named: FL, 2nd channel= FR and so on... [18:22] <ElMarikon> as I said, doing that with QuickTime is easy (via gui) and ffmpeg keeps the names, but how to initially assign them, not workling with an eyternal tool for that?! [18:22] <smj> hey... I'm not sure, but I might have fixed the desync problem by giving frame rate as the output option instead of an input option [18:23] <ElMarikon> smj: but then you drop/duplicate frames.. [18:23] <ElMarikon> do u want that? [18:23] <smj> yes. [18:23] <smj> while streaming. [18:33] <atog> I'm using ffmpeg to record audio from a public stream at predetermined times. The content that I'm trying to capture is preceeded by a prerecorded audio cue. Do any of you know how I might compare the input stream to a copy of the cue so that I can begin recording once the cue has been played? [18:36] <ElMarikon> atog: I don't get that... what do u wanna compare [18:36] <atog> ElMarikon: I want to compare a live audio stream to a prerecorded cue. Once the cue is heard on the live stream I want to begin recording [18:37] <durandal_1707> ElMarikon: there is -map_channel [18:39] <ElMarikon> durandal_1707: thanx, but as i wrote it is not about mapping the channels, but about labeling them... [18:39] <durandal_1707> where would be label put? [18:41] <ElMarikon> so... I have to change this: [18:41] <ElMarikon> Metadata: [18:41] <ElMarikon> creation_time : 2013-04-10 22:12:07 [18:41] <ElMarikon> handler_name : Apple Alias Data Handler [18:41] <ElMarikon> Stream #0:18(eng): Audio: pcm_s24le (in24 / 0x34326E69), 48000 Hz, mono, s32, 1152 kb/s [18:41] <ElMarikon> to that: [18:41] <ElMarikon> Metadata: [18:41] <ElMarikon> creation_time : 2013-04-10 22:12:07 [18:41] <ElMarikon> handler_name : Apple Alias Data Handler [18:41] <ElMarikon> Stream #0:18(eng): Audio: pcm_s24le (in24 / 0x34326E69), 48000 Hz, 1 channels (LFE), s32, 1152 kb/s [18:42] <ElMarikon> meaning: i have to tell ffmpeg: THIS is the LFE, that channel is the FL and so on... [18:42] <durandal_1707> open feature request on our trac [18:42] <ElMarikon> NO remap. I know how to do that... [18:43] <durandal_1707> thing is that currently 1 channel is always mono [18:43] <ElMarikon> ffmpeg can pass these labels through, but I don't know how to create them... [18:43] <durandal_1707> how ffmpeg pass such labels? [18:44] <durandal_1707> do you have file where it says anything different from "mono" ? [18:47] <ElMarikon> yes. [18:47] <ElMarikon> created by Quicktime... [18:48] <ElMarikon> if i just map the channels to a new.mov, ffmpeg just keeps the labels. [18:50] <durandal_1707> have link to short sample? [18:50] <durandal_1707> i'm certainly sure this is mov feature that is missing in muxer [18:51] <durandal_1707> because if you do -c copy it should be keept [18:51] <durandal_1707> if not, than its missing and so open bug report [18:55] <ElMarikon> i check that now... [18:56] <ElMarikon> so... it keeps the label even if i change the codec and /or mapping... [19:00] <ElMarikon> but just from mov to mov. It disappears, when i write an avi/mkv... [19:01] <durandal_1707> because avi/mkv does not have that feature [19:01] <durandal_1707> it seems user is not allowed to change those... [19:05] <ElMarikon> well... u can remove them, by saying map_metadata -1 [19:06] <ElMarikon> so u're saying, options are: keep or remove, nothing else!? [19:06] <durandal_1707> afaik they are set by "chan" tag [19:12] <cliente> can ffmpeg dump the audio of the wmv format? [19:15] <ElMarikon> of cause... [19:16] <cliente> cause? [19:16] <ElMarikon> durandal_1707: I can't find anything about that in this "chan" option... [19:17] <durandal_1707> ElMarikon: its metadata key, and afaik not settable from muxer/user [19:18] <durandal_1707> s/settable/ignored [19:18] <cliente> I have been trying with vlc and the audio seem to get distorted [19:18] <durandal_1707> ElMarikon: but try setting -channel_layout [19:36] <ElMarikon> i did try that of cause... in several ways... [19:36] <ElMarikon> durandal_1707: what codecs are in the file? [20:39] <sean-w> Is there any way to convert AIFFs to MP3s while retaining metadata? [20:40] <xlinkz0> where can i see what ffmpeg does when given a rtsp input stream? [20:42] <ElMarikon> sean-w: you could try to mess around with the -map_metadata option... [20:43] <ElMarikon> xlinkz0: what does it say? [20:43] <xlinkz0> no i mean how it sends rtsp commands etc [20:50] <ElMarikon> oh... sorry... not a single clue... [21:03] <xlinkz0> more particularly i need to know to which RTSP command the url is used on [21:03] <xlinkz0> or if the url is passed through the http api [21:11] <sean-w> xlinkz0: Maybe sniff some traffic with Wireshark? [21:24] <xlinkz0> thanks that's a good idea [22:09] <jbwiv> guys, I'm trying to convert an mp4 to wmv. I can do this with ffmpeg and it plays fine on linux, but when I try to play it on windows, it causes wmplayer to crash. Is this a known issue? [22:20] <otters> anyone on osx gotten sox to compile with ffmpeg support? [22:20] <otters> this is the tail of configure output on latest sox https://gist.github.com/joelteon/8a3c0bfe4555d95c3eb1 [22:21] <durandal11707> otters: you are asking for sox help on wrong channel [22:29] <otters> oh [22:29] <otters> well #sox is empty [22:30] <durandal11707> sox is even removing ffmpeg support [22:31] <otters> then what do I use to merge two m4bs together? [22:31] <durandal11707> what? [22:31] <otters> what do you mean, "what" [22:32] <durandal11707> what is m4bs? [22:33] <otters> it's an m4a with chapters [22:34] <durandal11707> i dont think sox supports m4a [22:34] <durandal11707> so whatever you do can be done with ffmpeg alone [22:35] <otters> it's an audiobook [22:39] <otters> okay it doesn't look like there exists any program capable of concatenating two m4bs [22:42] <tmatth> otters: http://ubuntuforums.org/showthread.php?t=1900761 [22:42] <otters> tmatth: you are the reincarnation of jesus christ [22:43] <ElMarikon> wrong, that's me..! [22:44] <durandal11707> same can be done with ffmpeg, there is documentation... [22:44] <ElMarikon> well... he found his way... [22:48] <ElMarikon> so... i still did not find a solution 4 my problem here... [22:48] <ElMarikon> I need to label the audio channels in a mov container the right way: [22:48] <ElMarikon> in: Audio: pcm_s16le (sowt / 0x74776F73), 48000 Hz, mono, s16, 768 kb/s [22:49] <ElMarikon> out: Audio: pcm_s16le (sowt / 0x74776F73), 48000 Hz, (FL), s16, 768 kb/s [22:49] <ElMarikon> i just don'tr get how to change the channel names... [22:49] <durandal11707> i told you that is not currently possible, open bug if you ever want it get fixed [22:50] <ElMarikon> where do u know that from? [22:50] <ElMarikon> i do see it is possible. [22:50] <ElMarikon> the only question is how... [22:51] <otters> heh, mp4box [22:51] <otters> it actually can't be done with ffmpeg [22:52] <otters> which can't output m4b [22:52] <otters> or doesn't understand how [22:52] <ElMarikon> but it can read and pass on these tags... [22:52] <ElMarikon> oh sorry... [22:53] <durandal11707> ElMarikon: yes, but you cannot really control them [22:54] <durandal11707> otters: m4b is just extension [22:55] <otters> durandal11707: ah...that might be it [22:56] <otters> because it can output to *.mp4 just fine >_> [22:56] <otters> thanks [22:59] <durandal11707> otters: its probably some extra few bytes change, i could add support for it, funny sox uses ffmpeg for m4b but ffmpeg does not even know m4b exist ... [22:59] <otters> durandal11707: okay so ffmpeg merges the files together properly, but when I open the resulting file it thinks it's the length of the first file [22:59] <otters> I think it might be because the chapter offsets in both tracks start at 0 [23:00] <durandal11707> what you used to merge? [23:00] <otters> ffmpeg [23:00] <otters> oh [23:00] <durandal11707> but command... [23:00] <otters> ffmpeg -i file1.m4b -i file2.m4b -y out.mp4 [23:01] <otters> hang on, tmux won't let me select all of it [23:01] <durandal11707> but if worked with sox? [23:01] <otters> no [23:02] <durandal11707> so why you asked for sox help then :))) [23:02] <otters> because i thought sox could do it [23:02] <otters> I just tried ffmpeg and it "worked" [23:03] <durandal11707> well there is concat demuxer [23:03] <durandal11707> !doc [23:14] <SeanDuncan_> I'm trying to use x264's qpfile option through ffmpeg's 'x264opts' option but qpfile doesn't seem to be working from there. is it called something else in ffmpeg? [23:14] <SeanDuncan_> I know there is the 'force keyframes' option but I'm looking to set frame types at a frame level [23:17] <SeanDuncan_> the big picture of what I'm trying to do is a pass=1 with x264, with mbtree enabled, while maintaining keyframe placement of past encodes (qp file generated from past .stats files) [23:19] <otters> https://gist.github.com/joelteon/038ea6b7317d7fef2cf2 [23:19] <otters> so all I really need to do is increment the chapter offsets and chapter numbers on the second input track [23:20] <otters> or...something. [23:21] <durandal11707> i dont think thats currently possible, open bug report if you want such feature [23:21] <otters> rats [23:24] <ElMarikon> durandal11707: if you are interested, I found the solution for my Problem: ffmpeg -i stereo.wav -map 0:0 -map 0:0 -map_channel 0.0.0:0.0 -channel_layout:0 FL -map_channel 0.0.1:0.1 -channel_layout:1 FR -c:a pcm_s16le tagged.mov [23:25] <ElMarikon> that tags channel0 as F(ront)L(eft) and channel1 as F()R() [23:25] <ElMarikon> so, no need for a bug report... thanx 2 u all! [23:26] <ElMarikon> otters: if it helps, you can just skip the chapters... [23:26] <ElMarikon> like: -map_chapters -1 [23:28] <durandal11707> ElMarikon: yes, i even mentioned to try with -channel_layout (but i did not pushed as i did not expect it to work) [23:29] <otters> ElMarikon: having chapters is the whole point of m4b [23:29] <durandal11707> ElMarikon: you could even add it to our wiki... [23:29] <ElMarikon> well... i do not know, but maybe there is a way to export them as text file and then offset them... [23:30] <durandal11707> for chapters i could swear you can't edit them, just remap/dump them [23:31] <ElMarikon> durandal11707: well, I also was not sure if it works, because i fritst tried to tag as FC, which for ffmpeg is the same as mono, so I had no tag then..:-| [23:31] <durandal11707> or even creating new ones from scratch [23:31] <durandal11707> is not currently possible [23:34] <ElMarikon> so, maybe it sounds funny, but handbrake has a good chapter handler and understands mp4 files... maybe it can be of help here... [23:34] <ElMarikon> ...a little off topc, i know... [23:34] <durandal11707> already mentioned mp4box too [23:34] <ElMarikon> :-) [23:35] <otters> mp4box gives me a mysterious error :) [23:35] <otters> "Error: Bad Parameter" [23:35] <ElMarikon> oh I just see, there is an export chapters option in handbrake, so maybe u can export, edit and then re-import... [23:35] <ElMarikon> otters: what parameters did u specify? [23:36] <otters> ElMarikon: [23:36] <otters> mp4box -cat file2.m4b file1.m4b [23:36] <otters> it says "Appeding file2.m4b" and gives me a progress bar [23:36] <otters> then, once it hits 100%, gives me that error and exits [23:37] <otters> Appending, actually [23:37] <ElMarikon> and the file does not work in the end? [23:40] <otters> it does, it has the length and chapters of the first input file but the filesize of both together [23:41] <ElMarikon> okay... i am not sure, but don't u have to say sth like mp4box -add file1.m4b -cat file2.m4b -new ...m4b [23:41] <ElMarikon> ? [23:42] <ElMarikon> and mybe -all [23:43] <ElMarikon> sorry, -keep-all [23:48] <ElMarikon> okay guys... i'T kindof midnight here, i am leaving... happy 1st of May, if that means sth to anyone:-) [23:48] <SeanDuncan_> OK, I'm back. sorry it took awhile. here is the pastebin of what I'm trying to do http://pastebin.com/u0FYfZnT [23:50] <ElMarikon> well... [23:50] <ElMarikon> seems, it does not like your qpfile [23:50] <ElMarikon> it does not even know the option... [23:54] <SeanDuncan_> yes, I see the same. it's just that x264 does have a option called 'qpfile' http://mewiki.project357.com/wiki/X264_Settings#qpfile [23:54] <ElMarikon> rite, but ffmpeg seems not to pass this on to the lib... [23:54] <SeanDuncan_> and I know the qp file is formated like the wiki says it should be [23:54] <SeanDuncan_> oh [23:54] <SeanDuncan_> dang [23:55] <SeanDuncan_> that's a shame [23:55] <ElMarikon> so, what u can do is: [23:55] <SeanDuncan_> pipe from ffmpeg to x264? [23:56] <ElMarikon> ffmpeg -i %vid% -vf scale=1280:720 -an -pix_fmt yuv420p -f yuv4mpegpipe -vsync 0 -v 4 - | x264 %youropts% out.mp4 [23:56] <ElMarikon> sorry, no vscale!! [23:56] <SeanDuncan_> right [23:56] <SeanDuncan_> I was hoping to avoid that method [23:56] <SeanDuncan_> totally doable, I understand [23:57] <ElMarikon> why? [23:57] <ElMarikon> it does not really change a thing... [23:57] <SeanDuncan_> any idea if ffmpeg plans to allow for qpfile via x264opts? [23:57] <ElMarikon> not a single clue, i am just assuming... [23:58] <durandal11707> SeanDuncan_: did you make sure it actually works with x264 alone? [00:00] --- Wed May 1 2013
