Detailed Description

H.264 / RTP Code (RFC3984).

Author:

Ryan Martell <rdm4@martellventures.com>

Note:

Notes: Notes: This currently supports packetization mode: Single Nal Unit Mode (0), or Non-Interleaved Mode (1). It currently does not support Interleaved Mode (2). (This requires implementing STAP-B, MTAP16, MTAP24, FU-B packet types)

TODO: 1) RTCP sender reports for udp streams are required..
