[MPlayer-dev-eng] [PATCH] reset vf error before codec init

[Reimar Döffinger]

Hello,
when multiple codecs are tried (mpegpes and mpeg12 was the problematic
case here), init can incorrectly fail with "FATAL: Could not initialize
video filters (-vf) or video output (-vo).".
The reason is that the first codec did fail due to some filter problems,
while the second one did not yet config the vo e.g. because it must wait
for a keyframe before it can do that.
Is attached patch okay?

Greetings,
Reimar Döffinger
