[Live-devel] Question About PAT/PMT in MPEG2

[Pme]

Thanks for the quick response. One other question:

I implemented the DummySink, but I think I need to modified the data I'm getting before passing it to FFMPEG (header file and other stuff. I've read that's necessary for H.264, but not sure for MPEG-TS). Is that right? If is the case, would you mind pointing me to an example, MPEG1or2VideoRTPSink maybe?

Thanks a lot and regards.

My question is: Is it possible to obtain the PAT and PMT information  before I  pass the frames to FFMPEG with help of the live555 library, or does the live555 library has nothing to do with this task and it should be handle by FFMPEG?
