[Libav-user] Receiving MPEGTS and fifo buffer overflows

Thank you for your quick responses.

I do see this problem happen usually when i start getting errors. How 
can I avoid getting errors? I dont think the errors are from the input 
stream but my inability to process the stream.

The machine is an 8 CPU AMD Opeteron running at 2.1Ghz. I think that 
should be fast enough.
How do I programmatically handle the errors? Is there a callback I can 
set to be called when I start getting errors?
