Patch implementing STAP-A for the RTP H.264 payloader
RFC 6184 (https://tools.ietf.org/html/rfc6184#section-5.7) describes how to
aggregate (bundle) small RTP packets (typically SPS/PPS); this can improve
bandwidth in some cases.
The rtph264depay already supports depayloading such bundled packets, but so far
the payloader does not rtph264pay does not; attached patch attempts to change
that.
Some notes:
- By default, no aggregation is done, but there's a property "do-aggregate" now
to enable this
- I've attempted to change the existing payloader as little as possible
Patch is against git HEAD.
