Please do not hijack threads, but start a new subject if that is what is
needed. You are also expected to provide complete uncut console output
to show what has happened.

Since you are are asking a question about hardware integration, this may
not be possible and suggests that this may not be the most appropriate
forum to ask about such matters. Have you tried libav-user?
