This issue has already been fixed in the ffmpeg fork for LAV-Filter.

#1582(avfilter:new): Banding/discoloration in darker gradients when converting to rgb24

#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.

#314: OpenAL device does not work on OS X ----------------------+-------------------------- Reporter: nieder | Type: enhancement Status: new | Priority: normal Component: avdevice | Version: git-master Keywords: | Blocked By: Blocking: | Reproduced: 0 Analyzed: 0 | ----------------------+-------------------------- configure is not set to find openal on OS X. The fix for the linker check is easy: add "-Wl,-framework,OpenAL" to the list of flags to check {{{ -enabled openal && { { for al_libs in "${OPENAL_LIBS}" "-lopenal" "-lOpenAL32"; do +enabled openal && { { for al_libs in "${OPENAL_LIBS}" "-lopenal" "-lOpenAL32" "-Wl,-framework,OpenAL"; do }}} I don't know how to fix the header check to look for multiple possibilities, but on OS X the header in the OpenAL framework is found in OpenAL/al.h (not AL/al.h like in linux). If I change the header check in configure and the includes in libavdevice/openal-dec.c, the build and linkage works well. However, running 'ffmpeg -f openal' as suggested in the manual fails with an malloc error, so this might just not be doable on OS X. {{{ nieder $ /usr/local/ffmpeg-git/bin/ffmpeg -list_devices true -f openal -i dummy out.ogg ffmpeg version N-31036-g65eae2a, Copyright (c) 2000-2011 the FFmpeg developers built on Jun 27 2011 10:29:19 with gcc 4.0.1 (Apple Inc. build 5493) configuration: --prefix=/usr/local/ffmpeg-git --mandir=/usr/local /ffmpeg-git/share/man --disable-static --enable-shared --enable-gpl --enable-version3 --enable-postproc --enable-pthreads --enable-x11grab --enable-bzlib --enable-libcelt --enable-libopencore-amrnb --enable- libopencore-amrwb --enable-libdirac --enable-libfreetype --enable- libmp3lame --enable-libopenjpeg --enable-librtmp --enable-libschroedinger --enable-libspeex --enable-libtheora --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libxvid --enable-openal --enable-zlib --disable- debug --extra-cflags='-I/sw/lib/libspeex1/include -I/sw/include -I/usr/X11R6/include' --extra-ldflags='-L/sw/lib/libspeex1/lib -L/sw/lib -L/usr/X11R6/lib' libavutil 51. 10. 0 / 51. 10. 0 libavcodec 53. 7. 0 / 53. 7. 0 libavformat 53. 4. 0 / 53. 4. 0 libavdevice 53. 2. 0 / 53. 2. 0 libavfilter 2. 24. 0 / 2. 24. 0 libswscale 2. 0. 0 / 2. 0. 0 libpostproc 51. 2. 0 / 51. 2. 0 [openal @ 0x200a800] List of OpenAL capture devices on this system: [openal @ 0x200a800] Built-in Microphone dummy: Immediate exit requested nieder $ /usr/local/ffmpeg-git/bin/ffmpeg -f openal -i 'Built-in Microphone' out.ogg ffmpeg version N-31036-g65eae2a, Copyright (c) 2000-2011 the FFmpeg developers built on Jun 27 2011 10:29:19 with gcc 4.0.1 (Apple Inc. build 5493) configuration: --prefix=/usr/local/ffmpeg-git --mandir=/usr/local /ffmpeg-git/share/man --disable-static --enable-shared --enable-gpl --enable-version3 --enable-postproc --enable-pthreads --enable-x11grab --enable-bzlib --enable-libcelt --enable-libopencore-amrnb --enable- libopencore-amrwb --enable-libdirac --enable-libfreetype --enable- libmp3lame --enable-libopenjpeg --enable-librtmp --enable-libschroedinger --enable-libspeex --enable-libtheora --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libxvid --enable-openal --enable-zlib --disable- debug --extra-cflags='-I/sw/lib/libspeex1/include -I/sw/include -I/usr/X11R6/include' --extra-ldflags='-L/sw/lib/libspeex1/lib -L/sw/lib -L/usr/X11R6/lib' libavutil 51. 10. 0 / 51. 10. 0 libavcodec 53. 7. 0 / 53. 7. 0 libavformat 53. 4. 0 / 53. 4. 0 libavdevice 53. 2. 0 / 53. 2. 0 libavfilter 2. 24. 0 / 2. 24. 0 libswscale 2. 0. 0 / 2. 0. 0 libpostproc 51. 2. 0 / 51. 2. 0 mpeg(49840,0xa025b720) malloc: *** error for object 0x1e2c0e0: incorrect checksum for freed object - object was probably modified after being freed. *** set a breakpoint in malloc_error_break to debug mpeg(49840,0xa025b720) malloc: *** error for object 0x1e2c0e0: incorrect checksum for freed object - object was probably modified after being freed. *** set a breakpoint in malloc_error_break to debug [openal @ 0x200a800] Error: ALC Invalid Device Bus error }}} -- Ticket URL: <http://ffmpeg.org/trac/ffmpeg/ticket/314> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

#1578(undetermined:new): variable FPS incorrect frame length

#1578: variable FPS incorrect frame length -------------------------------------+------------------------------------- Reporter: kubabrecka | Type: defect Status: new | Priority: normal Component: | Version: undetermined | unspecified Keywords: | Blocked By: fps,framerate,vfr,qtrle | Reproduced by developer: 0 Blocking: | Analyzed by developer: 0 | -------------------------------------+------------------------------------- I have a sample video to reproduce this bug - see attachment. The video is in Apple Animation codec (qtrle) with variable frame rate and contains only 5 frames. Frames 1,2,4 and 5 are displayed for a very short time, but frame 3 is much longer. When I extract all the frames into PNGs with this command: ./ffmpeg -vsync 2 -i apple-animation-variable-fps-bug.mov -vf "[in]showinfo[out]" out/img%04d.png it's fine, I get 5 PNG files, and the timestamps shown on the output are correct: n:0 pts:0 pts_time:0 pos:48 n:1 pts:600 pts_time:0.2 pos:4335 n:2 pts:1300 pts_time:0.433333 pos:8286 n:3 pts:7300 pts_time:2.43333 pos:12518 n:4 pts:8100 pts_time:2.7 pos:16642 as you can see, frame n:2 (the third frame) is displayed for much longer than the others. However, when I run this command to dump the frames with a constant FPS: ./ffmpeg -i apple-animation-variable-fps-bug.mov -r 30 out/img%04d.png the frames are dumped with wrong timing. The "long" frame was 2 seconds long, so it should be in about 60 frames (with FPS 30), but instead it only gets 7 frames. But the next frame which should be very short is dumped into 60 frames. It seems that the conversion between variable FPS into constant FPS incorrectly assigns frame length into the next frame. -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/1578> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker
