[Live-devel] timestamps of B frame in mpeg-4 video elementary streaming

Hi Ross,

I just want to confirm that during mpeg-4 video
elementary streaming, if there is B frame in the video
stream, the timestamps for those packets with data of
B frame should be the same as previous packets of P or
I frame, Is that right? Since I look
into the source of MPEG4VideoStreamFramer.cpp, you 
don't do any processing about timestamps when the
frame is B. 
Then at the decoder side, the decoder receive those
packets with same timestamps, however, 
those packets maybe belong to different frame and does
it know present them at different time?

Thank you for clarification.

Paul
