#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

#1582: Banding/discoloration in darker gradients when converting to rgb24 ----------------------------------+--------------------------------------- Reporter: y3kcjd5 | Type: defect Status: new | Priority: normal Component: avfilter | Version: unspecified Keywords: win64 | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | ----------------------------------+--------------------------------------- Summary: I've discovered that when I'm converting videos to the rgb24 format (in attempting to use the libx264rgb codec) I get banding and discoloration in darker areas with (color) gradients. To eliminate the possibility that it was the codec (as opposed to the format filter) causing the problem, I did some tests converting the video to .png images. Specifically, I found that: yuv420p10le(source video) -- looks nice yuv420p10le -> rgb24 -- banding/discoloration yuv420p10le -> rgb48be -- looks nice yuv420p10le -> rgb48be -> rgb24 -- banding/discoloration yuv420p10le -> yuv420p -> rgb24 -- banding but no discoloration I assume that the banding in the yuv420p example is simply a result of the reduced colorspace, but I don't see why any of the other conversions should result in any visible changes. I'm using one of Zeranoe's windows builds (win7 64bit) so I don't know if this happens on Linux. Log file output for the yuv420p10le->rgb24 example follows: {{{ ffmpeg started on 2012-07-28 at 10:56:16 Report written to "ffmpeg-20120728-105616.log" Command line: ffmpeg -i vtst0.mp4 -map 0:0 -vsync 0 -report -filter:v "format=rgb24" "tst%03d.png" ffmpeg version N-42704-g85761ef Copyright (c) 2000-2012 the FFmpeg developers built on Jul 20 2012 20:39:19 with gcc 4.7.1 (GCC) configuration: --enable-gpl --enable-version3 --disable-w32threads --enable-runtime-cpudetect --enable-avisynth --enable-bzlib --enable- frei0r --enable-libass --enable-libcelt --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libfreetype --enable-libgsm --enable- libmp3lame --enable-libnut --enable-libopenjpeg --enable-librtmp --enable- libschroedinger --enable-libspeex --enable-libtheora --enable-libutvideo --enable-libvo-aacenc --enable-libvo-amrwbenc --enable-libvorbis --enable- libvpx --enable-libx264 --enable-libxavs --enable-libxvid --enable-zlib libavutil 51. 65.100 / 51. 65.100 libavcodec 54. 42.100 / 54. 42.100 libavformat 54. 18.100 / 54. 18.100 libavdevice 54. 1.100 / 54. 1.100 libavfilter 3. 2.100 / 3. 2.100 libswscale 2. 1.100 / 2. 1.100 libswresample 0. 15.100 / 0. 15.100 libpostproc 52. 0.100 / 52. 0.100 [mov,mp4,m4a,3gp,3g2,mj2 @ 00000000002e2ec0] Format mov,mp4,m4a,3gp,3g2,mj2 probed with size=2048 and score=100 [mov,mp4,m4a,3gp,3g2,mj2 @ 00000000002e2ec0] ISO: File Type Major Brand: isom [mov,mp4,m4a,3gp,3g2,mj2 @ 00000000002e2ec0] File position before avformat_find_stream_info() is 7074306 [h264 @ 00000000002f40a0] no picture [mov,mp4,m4a,3gp,3g2,mj2 @ 00000000002e2ec0] All info found rfps: 23.750000 0.011875 rfps: 23.833333 0.004757 rfps: 23.916667 0.000859 rfps: 24.000000 0.000180 rfps: 24.083333 0.002721 rfps: 24.166667 0.008482 rfps: 24.250000 0.017461 rfps: 47.666667 0.019029 rfps: 47.750000 0.009623 rfps: 47.833333 0.003436 rfps: 47.916667 0.000469 rfps: 48.000000 0.000722 rfps: 48.083333 0.004194 rfps: 48.166667 0.010885 rfps: 23.976024 0.000046 rfps: 47.952048 0.000183 [mov,mp4,m4a,3gp,3g2,mj2 @ 00000000002e2ec0] File position after avformat_find_stream_info() is 1243950 Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'vtst0.mp4': Metadata: major_brand : isom minor_version : 512 compatible_brands: isomiso2avc1mp41 encoder : Lavf54.18.100 Duration: 00:00:10.09, start: 0.000000, bitrate: 5607 kb/s Stream #0:0(und), 41, 1/1000: Video: h264 (High 10) (avc1 / 0x31637661), yuv420p10le, 1920x1080, 5604 kb/s, 23.98 fps, 23.98 tbr, 1k tbn, 47.95 tbc Metadata: handler_name : VideoHandler [buffer @ 0000000004ba0f20] Setting entry with key 'video_size' to value '1920x1080' [buffer @ 0000000004ba0f20] Setting entry with key 'pix_fmt' to value '72' [buffer @ 0000000004ba0f20] Setting entry with key 'time_base' to value '1/1000' [buffer @ 0000000004ba0f20] Setting entry with key 'pixel_aspect' to value '0/1' [buffer @ 0000000004ba0f20] Setting entry with key 'sws_param' to value 'flags=2' [buffer @ 0000000004ba0f20] Setting entry with key 'frame_rate' to value '24000/1001' [graph 0 input from stream 0:0 @ 0000000004d73980] w:1920 h:1080 pixfmt:yuv420p10le tb:1/1000 fr:24000/1001 sar:0/1 sws_param:flags=2 [Parsed_format_0 @ 0000000004d738e0] auto-inserting filter 'auto-inserted scaler 0' between the filter 'graph 0 input from stream 0:0' and the filter 'Parsed_format_0' [auto-inserted scaler 0 @ 0000000004d73b20] w:1920 h:1080 fmt:yuv420p10le sar:0/1 -> w:1920 h:1080 fmt:rgb24 sar:0/1 flags:0x4 [h264 @ 00000000002f40a0] detected 2 logical cores Output #0, image2, to 'tst%03d.png': Metadata: major_brand : isom minor_version : 512 compatible_brands: isomiso2avc1mp41 encoder : Lavf54.18.100 Stream #0:0(und), 0, 1/90000: Video: png, rgb24, 1920x1080, q=2-31, 200 kb/s, 90k tbn, 23.98 tbc Metadata: handler_name : VideoHandler Stream mapping: Stream #0:0 -> #0:0 (h264 -> png) Press [q] to stop, [?] for help [h264 @ 00000000003aa100] no picture DTS -42, next:-62146 st:0 invalid dropping [h264 @ 0000000004cdbf00] no picture frame= 3 fps=0.0 q=0.0 size= 0kB time=00:00:00.12 bitrate= 0.0kbits/s frame= 5 fps=3.1 q=0.0 size= 0kB time=00:00:00.20 bitrate= 0.0kbits/s frame= 7 fps=3.0 q=0.0 size= 0kB time=00:00:00.29 bitrate= 0.0kbits/s ... frame= 237 fps=2.6 q=0.0 size= 0kB time=00:00:09.88 bitrate= 0.0kbits/s No more inputs to read from, finishing.
