Hi All,

         host2: 192.168.0.102

         host1 transcode test.mkv from 00:00:00.00 to 00:00:10.00
         host2 transcode test.mkv from 00:00:10.00 to 00:00:00.00

         I have try use command on host2  bellow:
           ffmpeg -v debug -y -i kaka.mkv -strict -2 -ss 00:00:10.00
-t 00:00:10.00 -vcodec copy -acodec aac  -v debug -vf setpts=PTS+10/TS
-af asetpts=PTS+10/TS -f mpegts  -bsf h264_mp4toannexb b.ts
