[FFmpeg-devel] [PATCH] tcp: properly return EOF

[wm4]

There is no POSIX error code for EOF - recv() signals EOF by simply
returning 0. But libavformat recently changed its conventionts and
requires an explicit AVERROR_EOF, or it might get into an endless retry
loop, consuming 100% CPU while doing nothing.
