I'll try again: If you don't use -map 0, there is no guarantee that FFmpeg uses the first video stream (it is perfectly ok to use any of several video - or audio - streams if you do not explicitly specify one) and from the perspective of the second stream (that is 720x480), it is perfectly ok not to accept crop=0:0:1920:1080. Since you somehow manage to remove the "Stream mapping:" part of the output (or it wasn't printed for some unknown reason), you have to specify -map 0 to make this a bug. (Note that a very similar bug exists for audio if you have streams with different channel count.) ________________________________________________ FFmpeg issue tracker <[email protected]> <https://roundup.ffmpeg.org/issue2156> ________________________________________________
