Hi All,

       I want to transcode multimedia from mp4 to ts.

       I have one file named "a.mp4", it's video codec is "h264" audio
codec is "aac"

       duration time is "00:03:00.000"

       I have three computer, I want to transcode the a.mp4 to ts use
the three computer.
       three computer name:  serv1 , serv2 , serv3

       I want to transcode the a.mp4 on serv1, serv2,serv3.

       serv1 transcode a.mp4 00:00:00.000 - 00:01:00.000 to a-1.ts
       serv2 transcode a.mp4 00:01:00.000 - 00:02:00.000 to a-2.ts
       serv3 transcode a.mp4 00:02:00.000 - 00:03:00.000 to a-3.ts

       which auguments can do it like this?

       I have try it like this, but it have pts/pcr error when i play
the m3u8 on VLC

       The error message is bellow:
