    I disagree. If Mplayer can provide the basic functionality, then 
front end GUI's for editing can easily be put together in Python/TCL 
etc. I don't think anyone wants the functionality Adobe  Premier 
incorporated into mplayer but the simple ability to cut linear sections 
of video from a stream for encoding would be really useful. Personally I 
don't use X on my media playing/recording machine and really don't want 
to have to boot into X (in 640x480 on my TV) just to do a bit of 
encoding. Ideally I want to use mplayer as an embedded component of the 
Python based GUI I am using for playing/recording video to do quick 
edits of recorded media (commercials etc). All that's needed of mplayer 
is to output frame numbers to stdout that can be captured by the GUI, 
which can then passed to mencoder to encode between these frames.

    Mplayer is so close to being able to do this. The reason I want to 
do this with Mplayer and not another tool is because Mplayer is one of 
the few tools that read nuppelvideo, and is the only tool that reads 
nuppelvideo and can output good quality DivX video.

... and there is no reason that mencoder/mplayer can't be used as an 
emebedded component to do this. Certainly easier than someone 
implementing all the functions and codecs of mplayer in a standalone 
tool just so they can put a gui on it.
