#2307(FFmpeg:new): Stream segmenter bug if total recorded length > 12 hours

#2307: Stream segmenter bug if total recorded length > 12 hours -------------------------------------+------------------------------------- Reporter: dgillier | Type: defect Status: new | Priority: normal Component: FFmpeg | Version: 1.1.3 Keywords: segment, | Blocked By: duration | Reproduced by developer: 0 Blocking: | Analyzed by developer: 0 | -------------------------------------+------------------------------------- I'm recording UDP streams with transcoding to disk. UDP source are MPEGTS stream with MPEG2 encoding (TV channels). I'm transcoding and recording in H264 using 30 minutes chunks. After the #24 segment is recorded (so after 12 hours of recording) the audio duration info is wrong in the file (look like a signed vs unsigned variable problem). Here is what I'm doing : ffmpeg -i udp://xx.xx.xx.xx:5000 -map 0:0 -map 0:1 -s 640x360 -vcodec libx264 -g 60 -vb 500000 -strict experimental -vf yadif -acodec aac -ab 96000 -ac 2 -y -f segment -segment_format mp4 -segment_time 1800 /mnt/%03dt.mp4 I tried to change the audio codec to libvo_aacenc with the same result. So it seems to be related to the segmenter. Here is a copy of the ffmpeg dump when I inspect the file: Correct files (segment 0 to 24): [root@srv1 ~]# ffmpeg -i /mnt/video/www/2013-01-25/tf1/tf1-024.mp4 ffmpeg version 1.1 Copyright (c) 2000-2013 the FFmpeg developers built on Jan 12 2013 16:56:27 with gcc 4.4.6 (GCC) 20120305 (Red Hat 4.4.6-4) configuration: --enable-gpl --enable-libmp3lame --enable-libtheora --enable-libvo-aacenc --enable-libvorbis --enable-libvpx --enable-libx264 --enable-version3 libavutil 52. 13.100 / 52. 13.100 libavcodec 54. 86.100 / 54. 86.100 libavformat 54. 59.106 / 54. 59.106 libavdevice 54. 3.102 / 54. 3.102 libavfilter 3. 32.100 / 3. 32.100 libswscale 2. 1.103 / 2. 1.103 libswresample 0. 17.102 / 0. 17.102 libpostproc 52. 2.100 / 52. 2.100 [mov,mp4,m4a,3gp,3g2,mj2 @ 0x3156500] Invalid SampleDelta in STTS -2073690672 Input #0, mov,mp4,m4a,3gp,3g2,mj2, from '/mnt/video/www/2013-01-25/tf1/tf1-024.mp4': Metadata: major_brand : isom minor_version : 512 compatible_brands: isomiso2avc1mp41 encoder : Lavf54.59.106 '''Duration: 00:30:00.32''', start: 0.000000, bitrate: 662 kb/s Stream #0:0(und): Video: h264 (High) (avc1 / 0x31637661), yuv420p, 640x360 [SAR 1:1 DAR 16:9], 560 kb/s, 25 fps, 25 tbr, 12800 tbn, 50 tbc Metadata: handler_name : VideoHandler Stream #0:1(und): Audio: aac (mp4a / 0x6134706D), 48000 Hz, stereo, fltp, 96 kb/s Metadata: handler_name : SoundHandler At least one output file must be specified -------------------------------------------------------------------------- Bad files (segment #25 and more) [root@srv1 ~]# ffmpeg -i /mnt/026.mp4 ffmpeg version 1.1 Copyright (c) 2000-2013 the FFmpeg developers built on Jan 12 2013 16:56:27 with gcc 4.4.6 (GCC) 20120305 (Red Hat 4.4.6-4) configuration: --enable-gpl --enable-libmp3lame --enable-libtheora --enable-libvo-aacenc --enable-libvorbis --enable-libvpx --enable-libx264 --enable-version3 libavutil 52. 13.100 / 52. 13.100 libavcodec 54. 86.100 / 54. 86.100 libavformat 54. 59.106 / 54. 59.106 libavdevice 54. 3.102 / 54. 3.102 libavfilter 3. 32.100 / 3. 32.100 libswscale 2. 1.103 / 2. 1.103 libswresample 0. 17.102 / 0. 17.102 libpostproc 52. 2.100 / 52. 2.100 Input #0, mov,mp4,m4a,3gp,3g2,mj2, from '/mnt/video/www/2013-01-25/tf1/tf1-026.mp4': Metadata: major_brand : isom minor_version : 512 compatible_brands: isomiso2avc1mp41 encoder : Lavf54.59.106 ''' Duration: 12:21:15.64,''' start: 0.000000, bitrate: 22 kb/s Stream #0:0(und): Video: h264 (High) (avc1 / 0x31637661), yuv420p, 640x360 [SAR 1:1 DAR 16:9], 455 kb/s, 25 fps, 25 tbr, 12800 tbn, 50 tbc Metadata: handler_name : VideoHandler Stream #0:1(und): Audio: aac (mp4a / 0x6134706D), 48000 Hz, stereo, fltp, 3 kb/s Metadata: handler_name : SoundHandler At least one output file must be specified Any clue on this ?

#2078: FFMPEG created WTV files cannot be fast forwarded or fast rewound in Windows Media Center -------------------------------------+------------------------------------- Reporter: ramitbhalla | Type: defect Status: new | Priority: normal Component: | Version: undetermined | unspecified Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Summary of the bug: Any WTV file created by FFMPEG, they can be seeked directly in MCE but when one tries toe fast forward or rewind (using the FF and RW buttons on the remote or the console) it does not go beyond at best 1 FF or 1 RW. i.e. WTV files recorded by MCE one can press the FF button upto 4 times to get 4x fast forward. Files created by FFMPEG sometimes get 1x FF and never go beyond 1x FF, it just returns to normal play. This happens with any WTV file, so you can take any file you have in your archive and remux it to wtv and see the results. something as simple as: ffmpeg -i test.ts -c copy test.wtv I'm not uploading a sample since it can be reproduced with any file remuxed to WTV. -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/2078> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

(See https://developer.apple.com/library/mac/#documentation/QuickTime/QTFF/QTFFC…) These atoms are necessary for detecting the correct dimensions for some videos, since they take precedence in Quicktime over the normal TKHD (track header) width/height and over the track PASP (pixel aspect ratio). The attached patch adds support for these atoms. I can provide a sample video if desired. -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/1485> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

#2522: Give ffmpeg (better) mp4 chapter editing support -------------------------------------+------------------------------------- Reporter: otters | Type: Status: new | enhancement Component: | Priority: normal undetermined | Version: 1.2 Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- It would be cool to either 1. merge chaptered mpeg-4 files (m4b, etc.) and have the chapters + chapter offsets automatically adjusted 2. be able to do #1 manually. If I merge two m4bs right now, the resultant file has the length and chapters of the first. {{{ $ ffmpeg -i 04\ Harry\ Potter\ and\ the\ Goblet\ of\ Fire,\ Part\ 1.m4b -i 05\ Harry\ Potter\ and\ the\ Goblet\ of\ Fire,\ Part\ 2.m4b -y output.m4a ffmpeg version 1.2 Copyright (c) 2000-2013 the FFmpeg developers built on Apr 30 2013 13:13:33 with Apple LLVM version 4.2 (clang-425.0.28) (based on LLVM 3.2svn) configuration: --prefix=/usr/local/Cellar/ffmpeg/1.2 --enable-shared --enable-pthreads --enable-gpl --enable-version3 --enable-nonfree --enable-hardcoded-tables --enable-avresample --enable-vda --cc=cc --host- cflags= --host-ldflags= --enable-libx264 --enable-libfaac --enable- libmp3lame --enable-libxvid libavutil 52. 18.100 / 52. 18.100 libavcodec 54. 92.100 / 54. 92.100 libavformat 54. 63.104 / 54. 63.104 libavdevice 54. 3.103 / 54. 3.103 libavfilter 3. 42.103 / 3. 42.103 libswscale 2. 2.100 / 2. 2.100 libswresample 0. 17.102 / 0. 17.102 libpostproc 52. 2.100 / 52. 2.100 [mov,mp4,m4a,3gp,3g2,mj2 @ 0x7fb7f4015a00] stream 0, timescale not set [mov,mp4,m4a,3gp,3g2,mj2 @ 0x7fb7f4015a00] max_analyze_duration 5000000 reached at 5015510 microseconds Input #0, mov,mp4,m4a,3gp,3g2,mj2, from '04 Harry Potter and the Goblet of Fire, Part 1.m4b': Metadata: major_brand : mp42 minor_version : 1 compatible_brands: mp42mp41 creation_time : 2013-04-30 17:05:28 title : Harry Potter and the Goblet of Fire, Part 1 track : 4/12 album : Harry Potter genre : Audiobooks artist : J.
