Thanks for your hints. I'm trying to benchmark -vf fillborders (added the timer code in vf_fillborders.c), so Carl Eugen's suggestion to use /dev/zero as input would not make sense. I'll try with "-f null -". -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".
