This one is worked around by the removal of the aout keep feature. But it still affects the vout. And probably --sout-keep too.

The video output is utterly broken. As it stands, we have to choose between #1533 and #1637.

I give up.

I meant #1593 (this one), of course.

Now, you should sometime get "main interface warning: wants non-existing object" instead of a crash.
