[FFmpeg-devel] [PATCH] remove loop in udp_read

[aviad rozenhek]

the file udp.c provides a very useful API for handling udp traffic,
specifically I use it for handling raw mpegts packets.
however the fact the udp_read blocks forever makes it less useful in case no
traffic comes in.

I modified udp_read to return AVERROR(EAGAIN) in case there is currently no
data available,
and compensated for that by looping in two places in aviobuf.c

patch attached
