1 - Wrong mailing list. This should probably be on ffmpeg-user. 2 - What configure options did you use for ffmpeg? Why did you remove them? 3 - What "modifications" have you made"? 4 - What CPU do you have? One without AVX is either old, or limited (like Celerons and Pentiums) 5 - Why are you using an x264 from 2016? Have you "modified" it too? Next time just press 'q' to end encoding so we can see some stats. _______________________________________________ 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".
