Thanks for your help! I suspect, you are right on not suitable for performance test. ... and for sure not for algorithmic tests. Unfortunately my initial question is still open: ... but I ask, because I want to understand the purpose of the shorter options "-loop number" and "-stream_loop number" (or how to apply them correctly in the command line to get the wanted effect). -Ulf _______________________________________________ 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".
