We are working on an H.264 codec to pjsip/pjmedia.
The presented buffer to the encode function of the codec is too small
for the H.264 NAL.
Option 1, we would like to return entire NALs and let them be fragmented
at the RTP layer. Is this supported, and if so, how do we get
a bigger buffer to write into?
Option 2, we could do the RTP fragmentation ourself, but we have no way
to adjust the RTP header. We could save the other fragments for
a subsequent call, but we would then be sending NAL fragments
at the frame rate, rather than entire NALs at the frame rate.
We are using pjsip 1.0.3, if this is solved later on, please advise, and
we will re-prioritize our move to 1.6.
