#3231: Muxing libvorbis audio fails; no sound in the output file ---------------------------------+--------------------------------------- Reporter: gyunaev | Type: defect Status: new | Priority: normal Component: avcodec | Version: unspecified Keywords: vorbis | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | ---------------------------------+--------------------------------------- There seem to be an issue related to muxing vorbis audio in ffmpeg, both 2.1.1 release and GIT head. The issue is fairly easy to reproduce with the muxing.c example in the FFmpeg doc/example directory by issuing the following command: {{{ ./muxing test.webm }}} The resulting test.webm will play video fine with ffplay, and will have the audio track, but will output no sound. It does not generate any errors either. This issue is related to vorbis and not libvpx/webm container, which could be further proved by adding the following two lines to force muxing test.ogg into theora/vorbis: {{{ --- muxing.c.orig 2013-12-18 01:25:24.126903125 -0800 +++ muxing.c 2013-12-18 01:29:12.643882209 -0800 @@ -487,6 +487,7 @@ video_st = NULL; audio_st = NULL; + fmt->audio_codec = AV_CODEC_ID_VORBIS; if (fmt->video_codec != AV_CODEC_ID_NONE) { video_st = add_stream(oc, &video_codec, fmt->video_codec); } }}} (this patch is necessary because by default it attempts to mux test.ogg into theora/flac - which by the way fails right away). And running make and executing as following: {{{ ./muxing test.ogg }}} The resulted test.ogg will work exactly as test.webm above - ffplay will play only video and no sound. Further investigating this issue it looks like vorbis audio requires setting the frame->pts. Applying the following patch to muxing.c fixes the audio output: {{{ --- muxing.c.orig 2013-12-18 01:25:24.126903125 -0800 +++ muxing.c 2013-12-18 01:36:03.566844598 -0800 @@ -258,6 +258,9 @@ dst_nb_samples = src_nb_samples; } + static int audio_pts = 0; + frame->pts = audio_pts; + audio_pts += dst_nb_samples; frame->nb_samples = dst_nb_samples; avcodec_fill_audio_frame(frame, c->channels, c->sample_fmt, dst_samples_data[0], dst_samples_size, 0); }}} With this patch theora/vorbis audio mixes fine, and ./muxing test.ogg plays the sound. However this patch breaks muxing every other format - for example, .patched /muxing test.avi uses mpeg4/vorbis and loses sound after 4 seconds. It is also seem to be exclusively vorbis-specific. libtheora+flac in ogg muxes without problem, while mpeg4+vorbis in AVI experiences the audio loss. More important, it doesn't fix webm libvpx/libvorbis, so it may be a different issue. -- Ticket URL: <https://trac.ffmpeg.org/ticket/3231> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

It could follow the same syntax like %d for formatting. It also might be used as an input parameter, but the list of matching input files would have to be sorted first, I guess, to have a correct sequence of input files. -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/1452> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

#3259(undetermined:new): MP4 chapter metadata issues: map_metadata failures and weird/superflous text streams

#3259: MP4 chapter metadata issues: map_metadata failures and weird/superflous text streams -------------------------------------+------------------------------------- Reporter: y3kcjd5 | Type: defect Status: new | Priority: normal Component: | Version: undetermined | unspecified Keywords: mp4 | Blocked By: chapters metadata | Reproduced by developer: 0 Blocking: | Analyzed by developer: 0 | -------------------------------------+------------------------------------- OK, I'm having two really annoying problems with chapter metadata in mp4 files. The first one I'm dearly hoping is just command syntax misuse on my part, but I cannot for the life of me find documentation on the subject. The second problem involves much more weird behavior. I can't tell if the two problems are actually different symptoms of the same cause or not, but they both deal with mp4 chapter metadata, so I'm lumping them together for now. ENVIRONMENT: win764bit using latest builds from Zeranoe PROBLEM 1: If I have an mp4 file (e.g. "metatst.mp4") with chapters in it I can set chapter metadata using something like '''-metadata:c:0 title=ch_title''' and something like '''-map_metadata:s:0 0:s:0''' or even '''-map_metadata:s 0:s''' works, but when I try anything like '''-map_metadata:c:0 0:c:0''' I get a fatal error: {{{ ffmpeg started on 2013-12-30 at 22:04:55 Report written to "ffmpeg-20131230-220455.log" Command line: ffmpeg -i metatst.mp4 -report -map_metadata:c:0 0:c:0 -c copy metatst2.mp4 ffmpeg version N-59275-g9b195dd Copyright (c) 2000-2013 the FFmpeg developers built on Dec 21 2013 22:06:20 with gcc 4.8.2 (GCC) configuration: --enable-gpl --enable-version3 --disable-w32threads --enable-avisynth --enable-bzlib --enable-fontconfig --enable-frei0r --enable-gnutls --enable-iconv --enable-libass --enable-libbluray --enable-libcaca --enable-libfreetype --enable-libgsm --enable-libilbc --enable-libmodplug --enable-libmp3lame --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libopenjpeg --enable-libopus --enable- librtmp --enable-libschroedinger --enable-libsoxr --enable-libspeex --enable-libtheora --enable-libtwolame --enable-libvidstab --enable-libvo- aacenc --enable-libvo-amrwbenc --enable-libvorbis --enable-libvpx --enable-libwavpack --enable-libx264 --enable-libxavs --enable-libxvid --enable-zlib libavutil 52. 58.101 / 52. 58.101 libavcodec 55. 45.103 / 55. 45.103 libavformat 55. 22.100 / 55. 22.100 libavdevice 55. 5.102 / 55. 5.102 libavfilter 4. 0.100 / 4. 0.100 libswscale 2. 5.101 / 2. 5.101 libswresample 0. 17.104 / 0. 17.104 libpostproc 52. 3.100 / 52. 3.100 Splitting the commandline.

I couldn't find any documentation to that effect. PROBLEM 2: If I try to create an mp4 file with chapters in it and I do not include '''-map_metadata:c -1''' in my command line, the resulting file will, for some bizarre reason, get a weird text stream tacked on to it invisibly. This stream doesn't show up anywhere in the creation log, and cannot be edited by ffmpeg in any way (trying to modify or add to its metadata has no effect). but a subsequent ffprobe will reveal its presence. My best guess is that this 'stream' contains the chapter metadata, but I am confounded as to why chapter metadata should show up in its own little fake stream while all other metadata is handled transparently.

This means that even if there is no actual chapter metadata, one such superfluostream is (aggravatingly) still generated by default (as demonstrated above). -- Ticket URL: <https://trac.ffmpeg.org/ticket/3259> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker
