[FFmpeg-devel] [PATCH] Make av_get_random_seed not block when waiting for more entropy

I recently ran into a situation where av_get_random_seed() blocks for long 
times if a machine is out of entropy. Since most (all?) uses of 
av_get_random_seed() within ffmpeg don't really need full cryptographic 
strength, using /dev/urandom instead of blocking while waiting for data 
from /dev/random - the attached patch does this.
