[Live-devel] transcoding a videostream

[Frank van Eijkelenburg]

Hi all,

Currently I am using the proxy server functionality of live555. I have 
some camerastreams which are handled through the proxy server. A 
camerastream with url A can be viewed by playing url B from a VLC player 
for instance. For some cameras I have to pass  the camerastream through 
the VLC library (for transcoding for instance). I am able to do that 
from a command line:

cvlc -vvv rtsp://192.168.1.110:1234/axis-media/media.amp --sout 
'#rtp{sdp=rtsp://192.168.1.110:5678/transcoded.sdp}'

The user can use a VLC player to play either 
"rtsp://192.168.1.110:1234/axis-media/media.amp" (normal camerastream) 
or "rtsp://192.168.1.110:5678/transcoded.sdp" (transcoded camerastream).

My question is how to build this into my application? I figured out the 
necessary library calls of the VLC library, but where/how can I trigger 
the VLC library calls "libvlc_media_player_play" and 
"libvlc_media_player_stop". Do I need two ProxyServerMediaSession 
objects? One for normal and one for transcoded streams? Can you point me 
into the right direction?


Thanks in advance.
