Hi Steve,
While implementing a streamer out and streamer in for H.264, you need to ensure
the following:
On Server:
- SPS and PPS are used to generate sprop_parameter_sets. The 2 parameter sets
i.e. SPS and PPS should be encoded in base-64 format with a comma separating
the two. Do note that SPS and PPS information should not have the NALU start
code. This is passed along with SDP information
- While transmitting using livemedia library, you should strip off the NALU
start code i.e. 0x00 00 00 01.
On the receiver end:
- You need to gather SPS and PPS from SDP once your media sub-session is
created, which involved base64 decoding and adding a NALU start code (dependent
on the decoder connected at the output of receiver
- You should be receiving data NALU by NALU, but probably need to attach the
NALU start code at the starting of each packet received.
In general, you may require an interface to interact with
H264VideoRTPSource/H264VideoRTPSink classes.
Hope this helps.
Ganesh

Subject: [Live-devel] Receiver for H.264
Hi,
I am trying to write a receiver for H.264, but my efforts are vain.
I already have a successful streamer which start an rstp server, and was trying
to
write a sender/receiver as for mpeg1or2.
Actually my sender/receiver looks like the
testMPEG1or2Streamer/testMPEG1or2Receiver
without RSTP, and I took care to use the right SOurce/Sink class. FFmpeg
recognise the format, with "Duration: N/A, bitrate: N/A", and vlc is not able
to play it.
Con someone tell me what's missing??
Regards, Steve Jiekak
