Hello, I am running the latest CVS version of ffmpeg (2005-05-30) and I have some problems when I try to access a live feed from WMP or RealPlayer. ffserver and ffmpeg seem to work well until a client session is launched. In this point, ffserver starts logging several "error, non monotone timestamps ..." and buffer underflow messages. I had tried with older versions and the problem is the same. I tried ffmpeg capturing to a file and it worked well. I had also tried ffserver streaming a file and it worked well too. I attach ffserver's configuration and ffmpeg command line. Please, let me know if you need more information.
