[FFmpeg-devel] [PATCH] avformat/utils.c: allows av_read_frame to return after a timeout period.

[ggarra13 at gmail.com]

From: Gonzalo Garramuño <ggarra13 at gmail.com>

Moved the check inside if (pktl) as per Michael Niedermayer's suggestion.
This patch is based on one from bsenftner at earthlink.net.
