[MPlayer-dev-eng] [PATCH] avoid null dereference crash when -edlout w/o vid

[Robert Henney]

it's seems unfortunate that the EDL Mark command cannot be used on audio
only material (it could be utilizied as a low-tech way to generate
timings to a wav file for subtitling purposes, for instance), but it's
more unfortunate I suppose that a crash results if one attempts to use
it on material with no video stream.

the attached patch adds a sanity check that prevents the crash.

I didn't attempt to go further, but am hoping someone else might. :)
