[FFmpeg-devel] [PATCH 1/5] avformat/udp: avoid warning about always false comparision

[Kacper Michajłow]

socklen_t underlying type can be signed or unsigned depending on
platform. This is fine, just cast it to size_t before comparision.

Fixes: warning: result of comparison of unsigned expression < 0 is
       always false [-Wtautological-unsigned-zero-compare]
