[MPlayer-dev-eng] Re: Problem decoding a H.263+ stream

[Ross Finlayson]

FYI, the subject of this thread is now inaccurate, because mplayer (with 
recent ffmpeg codecs) can now play H.263+ RTP streams OK.  For example, the 
following now works OK:
     mplayer -fps 15 
rtsp://darwin.horizonlive.com:554/finlayson/sample-h263-ulaw-8000.mov

>it doesn't work if you're behind a masq-router.

NAT is usually not a problem for RTSP/RTP, as long as you're NATing UDP 
packets as well as TCP.  However, RTP won't work if you're behind a 
firewall that blocks UDP packets.

I've said this before, but it's worth repeating: If you are behind a 
firewall that blocks UDP, you are not able to fully participate in the 
Internet.  All voice-over-IP (IP telephony) uses RTP/UDP.  All Internet 
videoconferencing uses RTP/UDP.  All Internet television (and a lot of 
Internet radio) uses RTP/UDP.  So, you should *really* try to get your 
Internet connection fixed.

>there are even special rtsp proxies.

RTSP has an optional feature that allows the RTP data streams to be 
streamed within the TCP control connection.  Supporting this (as an option) 
is on my "to do" list.  Apple also has a (non-standard) option that allows 
RTSP commands to be sent over a HTTP connection as well.  I may end up 
supporting that as well.  (But, as always, features requested by paying 
customers take priority.)
