[Live-devel] Implement RTSP skip forward in mediaServer

[Steve Malenfant]

Is there a possible bug that after you request something higher than 3570
seconds it is not working on transport stream files? It always brings me
back to the same scene.

Transport file length : 20177187044 (20GB)
Index file lenght : 1151033004 (1.1 GB)

Thanks.
