[MPlayer-users] Re: where is the extra information file created for

[Hans Meine]

Hi again!

Did you read the DOC's encoding-tips? There is no such thing as "THE best 
quality" because that depends on
- the source stream's format and properties
- whether you do scaling
- which compatibility you want to have (hint: storing aspect for best 
quality/size ration, giving up compat. for non-mplayer players)
- and others..

Look closer. If you really do 2-pass, there MUST be a file as already posted 
in our last answers. There is no other way.

Sorry, ain't got no clue. ;-)

How mplayer reacts to non-intended usage cases is subject to change between 
any versions. Probably someone put sane default values in it but did not 
update the docs. It _is_ a good idea to provide parameters, anyways.
