Ferric <blondeel...@hotmail.com> added the comment: I've had the same issue converting yuvj422p(Canon camera) to yuv422p, but I don't think ffmpeg is the issue.
IMHO it's probably due to Mplayer (and ?other players) treating yuvj AS yuv. (Mplayer gives a message to this effect). This would cause the yuvj source be displayed with an erroneously high contrast (with cropping) because the range of values for yuv is lower than yuvj (see http://git.ffmpeg.org/?p=ffmpeg;a=blob;f=libavcodec/imgconvert.c#l49 and http://en.wikipedia.org/wiki/YCbCr). By comparison the ffmpeg output looks like it has low gamma... but it probably doesn't. In addition ffmpeg stills from the source and output look the same (no gamma change). So it doesn't 'see' any difference after conversion to the new format. ________________________________________________ FFmpeg issue tracker <iss...@roundup.ffmpeg.org> <https://roundup.ffmpeg.org/issue2049> ________________________________________________
