I suggest looking at how "openRTSP" outputs H.264 video data to a file. In
particular:
- See "testProgs/playCommon.cpp", line 830, and note the call to
"subsession->fmtp_spropparametersets()".
- See also the implementation of the "H264VideoFileSink" class
("liveMedia/H264VideoFileSink.cpp", line 66), and note how it parses the
'sprop-parameter-string' into SPS/PPS NAL-units, by calling
"parseSPropParameterSets()".
