[00:03] <burek> does anyone have any idea what happened here: http://pastie.org/3770857   the ffmpeg used is a static build from 1 machine, that is being run on another machine :/
[00:14] <CIA-17> ffmpeg: 03Reimar Döffinger 07master * r277f20c3c8 10ffmpeg/ (3 files in 2 dirs): (log message trimmed)
[00:14] <CIA-17> ffmpeg: lavf: always call avio_flush in av_write_trailer.
[00:14] <CIA-17> ffmpeg: Otherwise for muxers like e.g. latmenc that never call
[00:14] <CIA-17> ffmpeg: avio_flush (and do not have a write_trailer function)
[00:14] <CIA-17> ffmpeg: a part of the data will always be missing.
[00:14] <CIA-17> ffmpeg: Also update references for the voc muxer, which was also
[00:14] <CIA-17> ffmpeg: buggy before and did not write out all data.

[02:54] <burek> does AVI file keep index at the end of file?
[02:54] <burek> the guy has got a file
[02:54] <burek> that makes ffmpeg hang
[02:54] <burek> but it's 2.5gb
[02:54] <burek> would it be enough if only first 10mb are uploaded?
[02:55] <burek> http://pastebin.com/n1FpfX0x
[03:17] <burek> also, would you like me (or anyone else) to create a simple web form for submitting reports with attachments, instead of instructing people to use ftp and ML?
[03:17] <burek> I guess it would be more convenient that way..
[03:18] <burek> bug reports*
[03:27] <iive> burek: yes it usually keeps an index at the end. however if the file is bigger than 1gb (or 2), it would create a tree of indexes. (ODML2.0)
[03:27] <burek> :S
[03:27] <burek> I instructed the guy to  upload the first and last 10mb of the file
[03:27] <burek> he is still in the #ffmpeg

[10:07] <CIA-17> ffmpeg: 03Nicolas George 07master * r81a9d32f0d 10ffmpeg/ffmpeg.c: ffmpeg: move getutime to the start of the file.

[11:41] <CIA-17> ffmpeg: lavf: compute_pkt_fields, limit the pts upcorrection to mpeg
[11:41] <CIA-17> ffmpeg: The pts correction conflicts with the ogg vorbis demuxer.

[11:58] <hjt> hello
[11:58] <hjt> i
[11:59] <hjt> i compile ffmpeg in mingw,but ffmepg.exe didn't print any message.
[11:59] <hjt> can anybody help me?
[12:08] <michaelni> hjt, check http://ffmpeg.zeranoe.com/forum/
[12:09] <michaelni> but mingw compile worked fine a day or 2 ago 
[12:09] <michaelni> so its probably a issue on your side
[12:11] <hjt> should i set loglevel while compileing ffmpeg?
[12:16] <hjt> i add printf at the begin of ffmepg.c ,it didn't anything neither
[13:11] <CIA-17> ffmpeg: 03Jakub Stachowski 07master * r3b00fd5985 10ffmpeg/libavcodec/wmalosslessdec.c: (log message trimmed)

[13:11] <CIA-17> ffmpeg: If channel residues are have not been decoded from bitstream, they should be
[13:11] <CIA-17> ffmpeg: initialized to 0 instead of using values from previous subframe.
[13:11] <CIA-17> ffmpeg: This causes bursts of noise in silent parts of some files.

[13:48] <hjt> ;;)
[14:06] <michaelni> hjt, you still havnt solved it ?
[14:07] <michaelni> if so try maybe to compile a hello_world.c
[14:08] <michaelni> if that fails its not ffmpegs fault ...
[15:21] <Compn> michaelni : ask him for make output when he comes back :)
[15:24] <michaelni> Compn, can you take a quick look at the 0.8.11 news entry (spelling & such) ? maybe a little later as i just pushed but better late than never
[15:24] <Compn> sure
[15:24] <michaelni> thx
[15:25] <michaelni> s/later/late/
[15:26] <Compn> looks ok
[15:26] <michaelni> :)
[17:12] <ubitux> michaelni: you said yesterday ffmpeg shouldn't stop when unable to decode a frame; could you then check if it's a normal behaviour with this sample: http://lucy.pkh.me/samples/decode-error-stop.mkv
[17:12] <ubitux> if so, i'll open an issue
[17:13] <ubitux> but i'd like a previous check if possible :)
[17:14] <ubitux> it stops decoding around frame 1090 while it shouldn't stop
[17:14] <ubitux> (mplayer doesn't for instance, with the lavf/mkv and lavc/h264)
[17:52] <michaelni> ubitux, looks like a bug
[17:52] <ubitux> okay, will report
[17:53] <michaelni> but could easily be a duplicate of 11??
[17:53] <ubitux> ticket11 ?
[17:53] <michaelni> 1167
[17:53] <ubitux> :D
[17:53] <michaelni> patch on ML about that one
[17:54] <michaelni> didnt try with itt hough 
[17:54] <ubitux> why would it be related?
[17:54] <burek> hi, how can I check what audio codec is this: [flv @ 0x1e83a00] Could not find codec parameters (Audio: none ([8][0][0][0] / 0x0008), 5512 Hz, 1 channels)
[17:54] <ubitux> Compn: would you mind to copy this file to ffmpeg samples? (as "Matroska/decodec-error-stop-45sec.mkv" or sth like this maybe)
[17:54] <burek> just to make sure if the person didn't compile needed audio encoding library
[17:55] <michaelni> ubitux, how many frame is it supposed to transcode ?
[17:55] <michaelni> approximately
[17:55] <michaelni> with -an i get 1097
[17:57] <ubitux> mplayer goes up to ~55sec
[17:57] <ubitux> so something like 10sec after the bug at 45sec
[17:57] <ubitux> not sure how many frames it means
[17:57] <michaelni> not a duplicate of 1167 then i suspect
[17:59] <michaelni> not a regression, even ffmpeg-0.5 fails (1051 frames 45.71 sec)
[18:00] <ubitux> mplayer and mencoder seems to be able to deal with it
[18:00] <ubitux> but i'm not sure how :)
[18:01] <michaelni> with lavf demuxer ?
[18:01] <ubitux> yes afaict
[19:11] <Compn> burek : in flv source/spec is 0x0008
[19:11] <Compn> burek :  i think its intel audio
[19:11] Action: Compn should check
[19:12] <Compn> ubitux : what file ... to where ?
[19:15] <Compn> arg its not in libavformat/flv.h
[19:16] <silverrocker> I'm trying to load a file (that I craeted with ffmpeg -vcodec libx264 encodedfile.h264) using the example decodeing_encoding.c from doc/examples. I have changed the find codec line to  avcodec_find_decoder(CODEC_ID_H264). 
[19:17] <silverrocker> but the example doesn't seem to work properly (giving me only a part of the frame)
[19:17] <silverrocker> also giving some errors to stderr form the h264 codec itself
[19:17] <silverrocker> If I open the file with ffplay, it seems to work
[19:17] <silverrocker> what am I missing?
[19:18] <Compn> possibly the example code isnt up-to-date 
[19:18] <Compn> wrt new api :\
[19:18] <silverrocker> wrt?
[19:18] <Compn> with reguards to
[19:18] <silverrocker> ah, so how do I go form here?
[19:18] <Compn> i think the decoding api changed and no one fixed example stuff
[19:18] <Compn> well uh
[19:18] <Compn> have to get someone to reproduce the bug :)
[19:19] <silverrocker> Compn: if I poste my code and the file that I'm trying to use, can you help me?
[19:19] <Compn> silverrocker : no, i'm not good with code
[19:20] <silverrocker> ah ok :s
[19:29] <ubitux> Compn: this one: http://lucy.pkh.me/samples/decode-error-stop.mkv to let's say samples.ffmpeg.org; or maybe another place more appropriate?
[19:29] <Compn> sounds fine
[19:30] <Compn> done
[19:30] <ubitux> thanks :)
[19:30] <Compn> i just forgot your host addy
[19:30] <Compn> full urls are nice :)
[20:18] <silverrocker> ok, it seems that I can use the example decode_encode.c just for mpeg1 video. How can I extend this to be used for mpeg4 and others? 
[20:20] <silverrocker> I can find the video stream for any file and automatically find the codec needed but I need to do more stuff to get it working for any format (beside mpg1) it seems
