 Thanks a lot for everyone's help.I could capture m2ts data from a DV now.
Now I want to send them out through RTP, but some new error happens, i tried many times, but still failed.
please give me some help.

Re: About m2ts RTP

Edward Hervey

Hi,

  The problem is that the rtpmp2tpay element will not ensure that
outputted packets are smaller than 'mtu' bytes, and the udpsink borks
on that.
  There's one way to solve that by using mpegtsparse before the
payloader. mpegtsparse will output 188 bytes packets, which will be
properly payloaded.

     Edward
