[vlc-devel] Re: VoD Support for RTP over RTSP (RTP TCP) and RTSP/RTP in HTTP

[Brian Raymond]

One thing this work should allow, if it forces an overhaul of some of 
the RTSP code is the ability to more easily add RTSP ANNOUNCE support to 
VLC. This will allow VLC to dynamically push streams to DSS over RTSP 
and have it handle streaming. I looked at adding it in the past but it 
fell down in my priority list after looking at what was involved in 
reworking the code.
