[FFmpeg-user] The newest ffmpeg split video very slowly with async 2 or 1

[Tony Song]

The newest ffmpeg splits video very slowly sometimes which seems abnormal.

And ffmpeg which git vesion is
1fbd905bbb4ca4c8e15030bb80b6188ef4b0e135 works well with the all videos.

So i think the splitting command combination *-ss -t -async 2* which *-ss
-t* is before input file is somemistake.
