[MPlayer-dev-eng] [PATCH] mencoder crash on empty file

[Reimar Döffinger]

Hello,
when encoding an empty file (e.g. via -ss 99999999999999) mencoder
currently crashes at least with -ovc lavc.
The reason is that control with VFCTRL_FLUSH_FRAMES is called although
config has not been executed.
Attached patch would be one way to fix. Is it okay?
Another way would probably be to implement vo_config_count properly for
mencoder, too.

Greetings,
Reimar Döffinger
