[Live-devel] transcoding a videostream

[Frank van Eijkelenburg]

I am sorry if Iitwasn't clear enough. Your suggestion is exactly what I 
want to do: implement my own LIVE555 transcoding filter (based on 
libAV). My confusion is about the registering of urls and where to put 
the libAV play command. Do I need to register two urls: the "normal 
camerastream" and the "transcoded camerastream", or should it be enough 
to just use the "transcoded camerastream"? What happens if a player 
tries to play the "transcoded camerastream"? This will result in sending 
a RTSP play command to the camera, but does the libAV play command do 
the same? I have not totally clear what will happen and therefore need 
some suggestions in the right direction.

best regards,

Frank van Eijkelenburg
