[MPlayer-dev-eng] [PATCH] Avoid raising error when trying to load a vobsub.

[Clément Bœsch]

Hi,

A small patch to avoid the message "SUB: Could not determine file format"
each time a vobsub is loaded. The MPEG header is just checked a single
time (first line/packet) and after every other format detection failed.
