[Live-devel] SVC multi streaming transmission of separate layers

[jmdaa at iscte.pt]

Hi,

In trying to solve a SVC multi streaming transmission of
separate layers, using a standard MP4 container (i belive your server
dont support this container).
I manage to stream a mp4 container with
two movie track on it, but to two different IP (using only one streaming
server and two interface in the client).
When we stream our MP4
container we get this with
wireshark:

DO
YOU KNOW A WAY TO CHANGE THE SETUPRTSP IN YOUR CLIENT CODE (OPENRTSP)
TO INDICATE THAT THE TWO TRACK GO TO TWO DIFFERENT IP (INTERFACE) FOR
EXAMPLE:
