I'm trying to send H264 video over RTP and planning to write a simple mediastreamer application (similar to linphone-3.3.2/mediastreamer2/tests/mediastream.c) for doing the same. Now my application has a few restriction/pre-requisites , which are as follows :
1. The H264 profile has to be baseline 2. It has to be a byte-stream 3. It should contain SPS, PPS in the header after a specified time interval.
Point 1. is already implemented since the msx264 plugin is be default configured as baseline profile.
For configuring Point 2. , I set the annexb variable in "params.b_annexb" to 1. Now, the only remaining issue is Point 3.
What would be the best way to achieve it ?
This is what I was thinking :
- In msx264.c , enc_process(), the function x264_nals_to_msgb() creates a queue of the NAL units and packs it using rfc3984_pack(). - I would check for the payload identifier type and when I get SPS and PPS, packets, save them
- Then insert this queue on every pre-determined time interval, and pack it normally using rfc3984_pack(). Does this design make sense ? Can someone suggest anything better ?
