If the size somehow gets lost between lavf and lavc then the problem is there, and should be solved by not fudging the decoder. Moreover, if neither the codec, nor container can change the resolution, then how does that make anything different? Please, stop it with those patches. It takes energy and some worry to have to open up the ML and scan it for bad patches from people who really should know better every time. _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
