[Live-devel] m2v streaming packet loss

[Alexandre Pinot]

Hi all,

I am trying to use the Live.com code (from the common.cpp sample) to 
receive a m2v video stream from a live server.

I am using MPEG1or2VideoRTPSource as the packet source, but I do not 
receive all the data sent. I'm losing about 30% of the packets. However, 
MPlayer plays the same stream fine. As I'm streaming locally I'm not 
sure why I get such a high packet loss with my client code.
 
I also tried to activate the 'useTCP' option to fix this packet loss 
problem, but then I received too much data. About 30% more than 
expected. I think that there are some extra headers and checksums 
inserted in the stream before each slice. If I save that stream as raw 
from my client, VLC cannot read it (some artefacts appear on the movie) 
but MPlayer can.
 
Is there any explanation for the high UDP packet loss? How can I compensate?
What about the TCP stream? Should I implement some specific code to 
remove the extra data and rebuild the original stream? Is there a sample 
of such code?

Thank you for your help
