problems with vlc H.261 decode
Posted: 01 Dec 2012 21:23
I am having problems getting vlc to receive a RTP/H.261 video stream. I am using a separate SDP file:
All I get is a green screen and no video stream. Here is the message output:
Is there anything else I need to specify to fix the buffering problem??
Thanks,
-Andres
