[Live-devel] H.264 and MPEG2 Transport Stream

[David Arnold]

Ross,

Thank you for your suggestions.  I have been working with
MPEG2TransportStreamFromESSource using my H.264 source.  I needed to modify
MPEG2TransportMultiplexor so that it generates the appropriate "streamType"
for H.264.  Also, the multiplexor is calling my sources "doGetNextFrame()"
without considering the fDurationInMicroseconds.  Looking at the end of
doGetNextFrame() in MPEG2TransportStreamMultiplexor.cpp I see the following
comment:

" // NEED TO SET fPresentationTime, durationInMicroseconds #####
  // Complete the delivery to the client:
"

I don't understand how I can determine what the correct presentation time
and duration should be.

Thanks again,

Dave Arnold

One more thing: You may find the code for the "wis-streamer"
application <http://www.live555.com/wis-streamer/> useful.   This
code makes use of the "MPEG2TransportStreamFromESSource" class, in a
way that may be similar to your intended application.
