The HTTP tunneling *is* doing interleaved RTP. HTTP tunneling is the same as
interleaved RTP, except there's an additional layer where incoming traffic
is base64 encoded and pulled w/ a GET and outgoing traffic is base64 encoded
and push w/ POST.
If you decode the HTTP data you just get plain-ole RTSP/RTP in interleaved
transport mode, w/ a few QTSS-specific headers in the playback setup.
I think the Apple guys just surmised that if interleaving the payload
already cost in terms of higher latency and poorer flow control, why not
toss in HTTP tunneling and turn the mode into a failsafe that is actually
failsafe.
