My understanding is that if you simply build MEncoder from unmodified sources
and put the resulting binary together with your application on a CD or in an
installation package, then all you need to do is provide some means to get
the exact sources used to build that MEncoder binary at no additional charge.

However, if you modify MEncoder, then you must release all your
modifications under GPL as well.

I would suggest going over GPL with your lawyer, because none of us here are
lawyers and we cannot provide legal advice.

R.

oppression to develop psychic muscles.
