Hello again :) I've just noticed that by default, FFV1 chooses version "0". I thought it would be "1".
When adding "-level 1" it properly shows "ver:1". (and a proper value for "bps") == For example: Source video: https://media.xiph.org/video/derf/y4m/football_422_ntsc.y4m $ ffmpeg -i input.avi -c:v ffv1 -an output.avi $ ffprobe -debug 1 -i output.avi Shows: [ffv1 @ 0x2263b80] ver:0 keyframe:1 coder:0 ec:0 slices:1 bps:0 On the other hand: $ ffmpeg -i input.avi -c:v ffv1 -level 1 -an output.avi $ ffprobe -debug 1 -i output.avi Shows: [ffv1 @ 0x2c9eb80] ver:1 keyframe:1 coder:0 ec:0 slices:1 bps:8 Interestingly, the console output of both commands seems identical. Why is that so? Thanks in advance, Pb -- Complete uncut console output: // -------------------------- $ ffmpeg -i ../football_422_ntsc.y4m -c:v ffv1 -an output.avi // -------------------------- ffmpeg version N-75272-g5629143 Copyright (c) 2000-2015 the FFmpeg developers built with gcc 4.6 (Ubuntu/Linaro 4.6.3-1ubuntu5) configuration: --prefix=/usr/local --enable-gpl --enable-nonfree --enable-version3 --enable-postproc --enable-swscale --enable-avfilter --enable-pthreads --enable-bzlib --enable-zlib --enable-decoder=png --enable-encoder=png --samples=../fate-suite --enable-libfreetype --enable-libschroedinger --enable-libopenjpeg --disable-decoder=jpeg2000 --enable-libvpx --enable-libvorbis --enable-libx264 --enable-libfaac libavutil 55. 2.100 / 55. 2.100 libavcodec 57. 1.100 / 57. 1.100 libavformat 57. 0.100 / 57. 0.100 libavdevice 57. 0.100 / 57. 0.100 libavfilter 6. 2.100 / 6. 2.100 libswscale 4. 0.100 / 4. 0.100 libswresample 2. 0.100 / 2. 0.100 libpostproc 54. 0.100 / 54. 0.100 Input #0, yuv4mpegpipe, from '../football_422_ntsc.y4m': Duration: 00:00:12.00, start: 0.000000, bitrate: 167963 kb/s Stream #0:0: Video: rawvideo (Y42B / 0x42323459), yuv422p, 720x486, SAR 4320:4379 DAR 6400:4379, 30 fps, 30 tbr, 30 tbn, 30 tbc Output #0, avi, to 'output.avi': Metadata: ISFT : Lavf57.0.100 Stream #0:0: Video: ffv1 (FFV1 / 0x31564646), yuv422p, 720x486 [SAR 4320:4379 DAR 6400:4379], q=2-31, 200 kb/s, 30 fps, 30 tbn, 30 tbc Metadata: encoder : Lavc57.1.100 ffv1 Stream mapping: Stream #0:0 -> #0:0 (rawvideo (native) -> ffv1 (native)) Press [q] to stop, [?] for help frame= 360 fps= 45 q=-0.0 Lsize= 111033kB time=00:00:12.00 bitrate=75798.8kbits/s video:111019kB audio:0kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: 0.012829% // -------------------------- // -------------------------- $ ffmpeg_git -i ../football_422_ntsc.y4m -c:v ffv1 -level 1 -an output.avi // -------------------------- ffmpeg version N-75272-g5629143 Copyright (c) 2000-2015 the FFmpeg developers built with gcc 4.6 (Ubuntu/Linaro 4.6.3-1ubuntu5) configuration: --prefix=/usr/local --enable-gpl --enable-nonfree --enable-version3 --enable-postproc --enable-swscale --enable-avfilter --enable-pthreads --enable-bzlib --enable-zlib --enable-decoder=png --enable-encoder=png --samples=../fate-suite --enable-libfreetype --enable-libschroedinger --enable-libopenjpeg --disable-decoder=jpeg2000 --enable-libvpx --enable-libvorbis --enable-libx264 --enable-libfaac libavutil 55. 2.100 / 55. 2.100 libavcodec 57. 1.100 / 57. 1.100 libavformat 57. 0.100 / 57. 0.100 libavdevice 57. 0.100 / 57. 0.100 libavfilter 6. 2.100 / 6. 2.100 libswscale 4. 0.100 / 4. 0.100 libswresample 2. 0.100 / 2. 0.100 libpostproc 54. 0.100 / 54. 0.100 Input #0, yuv4mpegpipe, from '../football_422_ntsc.y4m': Duration: 00:00:12.00, start: 0.000000, bitrate: 167963 kb/s Stream #0:0: Video: rawvideo (Y42B / 0x42323459), yuv422p, 720x486, SAR 4320:4379 DAR 6400:4379, 30 fps, 30 tbr, 30 tbn, 30 tbc Output #0, avi, to 'output.avi': Metadata: ISFT : Lavf57.0.100 Stream #0:0: Video: ffv1 (FFV1 / 0x31564646), yuv422p, 720x486 [SAR 4320:4379 DAR 6400:4379], q=2-31, 200 kb/s, 30 fps, 30 tbn, 30 tbc Metadata: encoder : Lavc57.1.100 ffv1 Stream mapping: Stream #0:0 -> #0:0 (rawvideo (native) -> ffv1 (native)) Press [q] to stop, [?] for help frame= 360 fps= 54 q=-0.0 Lsize= 111033kB time=00:00:12.00 bitrate=75798.8kbits/s video:111019kB audio:0kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: 0.012829% // -------------------------- _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
