Description
I will attach the first frames of a cctv recording that contains mjpeg in avi. The mjpeg frames have a resolution of 704x288 and are gray, the avi header reports 704x576. The result are ugly green frames.
$ ffmpeg -i MSC2.avi -qscale 2 -vframes 123 out.avi ffmpeg version N-71919-ge31cdb5 Copyright (c) 2000-2015 the FFmpeg developers built with gcc 4.7 (SUSE Linux) configuration: --enable-gpl libavutil 54. 23.101 / 54. 23.101 libavcodec 56. 37.100 / 56. 37.100 libavformat 56. 31.102 / 56. 31.102 libavdevice 56. 4.100 / 56. 4.100 libavfilter 5. 16.101 / 5. 16.101 libswscale 3. 1.101 / 3. 1.101 libswresample 1. 1.100 / 1. 1.100 libpostproc 53. 3.100 / 53. 3.100 Input #0, avi, from 'MSC2.avi': Duration: 00:00:35.00, start: 0.000000, bitrate: 585 kb/s Stream #0:0: Video: mjpeg (MSC2 / 0x3243534D), yuvj422p(pc, bt470bg/unknown/unknown), 704x576, 3 fps, 3 tbr, 3 tbn, 3 tbc Metadata: title : ????i Please use -q:a or -q:v, -qscale is ambiguous [swscaler @ 0x3200060] deprecated pixel format used, make sure you did set range correctly Output #0, avi, to 'out.avi': Metadata: ISFT : Lavf56.31.102 Stream #0:0: Video: mpeg4 (FMP4 / 0x34504D46), yuv420p, 704x576, q=2-31, 200 kb/s, 3 fps, 3 tbn, 3 tbc Metadata: title : ????i encoder : Lavc56.37.100 mpeg4 Stream mapping: Stream #0:0 -> #0:0 (mjpeg (native) -> mpeg4 (native)) Press [q] to stop, [?] for help frame= 123 fps=0.0 q=2.0 Lsize= 4466kB time=00:00:41.00 bitrate= 892.3kbits/s video:4457kB audio:0kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: 0.190914%
The following produces a nicer output:
$ ffmpeg -i MSC2.avi -vcodec copy out%4d.jpg $ ffmpeg -framerate 3 -i out%4d.jpg -vf setdar=4/3 -qscale 2 out.avi
