Hi! (I recently posted this on -user, but as I fear this might be a bug, I decided to also post here (-devel).)
I have a problem where the resulting file from the following commands produce a transport stream file that does not display video. wget http://www.sample-videos.com/video/mp4/480/big_buck_bunny_480p_1mb.mp4 (Any mp4 file will probably be fine, but I used that one.) Reencode the h264 video into mpeg4: ffmpeg -i big_buck_bunny_480p_1mb.mp4 -acodec copy -vcodec mpeg4 big-mpeg4.mp4 Then convert the container from mp4 to transport stream: ffmpeg -i big-mpeg4.mp4 -codec copy big-mpeg4.ts The resulting file "big-mpeg4.ts" cannot be played by ffplay. It prints tons of logs, but this one seems most important. [mpeg4 @ 0x7f9af80008c0] [IMGUTILS @ 0x7f9afe8bb420] Picture size 0x0 is invalid Please note that if the operations are done in one single step, like this: ffmpeg -i ~/streams/big_buck_bunny_480p_1mb.mp4 -acodec copy -vcodec mpeg4 big-mpeg4-2.ts ... ffplay has no problem, video is shown. This behaviour is the same on these two ffmpeg versions: ffmpeg version 2.8.8-0ubuntu0.16.04.1 Copyright (c) 2000-2016 the FFmpeg developers (ubuntu 16.04 standard) ffmpeg version N-82217-gb642290 Copyright (c) 2000-2016 the FFmpeg developers (built myself) Any ideas what could be wrong here? /Fredrik Persson _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
