[FFmpeg-devel] [PATCH] avio: Avoid endless loop in case no data arrives

This does not seem right: the continue is only triggered by EINTR, which is
is a rather exceptional situation, and should not prevent ff_check_interrupt
from doing its work in the very next round.

I believe there may be something more complex at work here. Can you post a
complete command that exhibits the problem?
