It works with temporary buffers in RAM (-vo xv)
Anyway you can't implement something better there.
And such solution can be as generic thing.

You have very limited licence. Before I though that it caused by some
limitation in tempoary stuff like encoder odivx and so on.
But you forbit to have compiled collection of your sources!!!
GPL never forbit compile a program.
Every commercial program can be compiled with GPL'ed shared object.
Every commercial product communicates with GPL'ed kernel.
So it seems just as stupid limitation.

The licence doesn't affect products.
You can use GPL'ed gcc to compile commercial program.
The same as you can links with GPL objects if your program doesn't required.
its source.
What about header - they don't violate licence (at least I can rewrite them from scratch).

Licence of which part of COLLECTION forbits do that?

I guessed that mplayer is program but it seems that it was my mistake.
It's even not a program, wow!
Then what is it and why it does work after translating of this collection by gcc?
