Hi Rodney Baker,

  Thanks for your help, I'm a fish.
  I have tried with your suggestion, but the problem also, I'm sure i
using newset code, i use git pull today.

The input is :
ffmpeg -y -i a/kaka.mkv -scodec copy -vcodec copy -acodec copy -t 10
-bsf h264_mp4toannexb -f mpegts output.ts

the console output is:
