MPlayer does NOT follow the QT API. Why should it anyways?

Yes, the documentation lacks at some point, but...

This is in the documentation

This is in the documentation

This is in the documentation

This is in the documentation, though trying would be probably faster.

This is in the documentation

Do i understand you right, that you want to play
an audio file and a playlist simultanously?
If so, than this is also in the documentation.

This is also in the documentation

This is ofcourse not in the documentation. Why should it anyways?

This is also in the documentation

This is of course not in the documentation.

This is in the documentation

This is of course not in the MPlayer documentation
as it does not belong ther.

What is very obvious from your questions, is that you have
missed the first sentence of the man page (i think it's in
the HTML docs too): "MPlayer is a movie player".
If this sentence doesn't answer the particular question,
then the manpage will. Please note that the slave
interface is not documented in the html docs or the
manpage but in DOCS/tech/slave.txt as we assume that
one needs some conciderable understanding in what's going
on, which an average user cannot be assumed to have.
