I was thinking the answer easy but maybe not. I tried all combinations in this page but didn't succeed http://superuser.com/questions/322216/how-can-i-pipe-output-of-ffmpeg-to-ffplay -f rawvideo - | ffplay -f rawvideo - pipe:1 | ffplay -i - -f matroska - | ffplay - pipe:play | ffplay -i pipe:play and more Is it so difficult to get it? _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user
