[MPlayer-users] My question of the hour, does anyone know source inside out?

Very good and informative.  I actually surmised the slave-idle.patch was
probably prior to RC2 and therefore not going to fit perfect, however,
even with my limited skill in building these, I managed to understand the
diagram in the patch text.  I've cut-and-pasted the slave-idle.patch
below.  Maybe you can help me understand how to merge where I am
failing.

So, I am indeed working with the latest RC2 build, and presume by
looking at this
 patch there are going to be two files to be 'patched'

cfg-mplayer.h
mplayer.c

It is my understanding the + and - in this patch text signify the addition
or removal of certain lines, ... and the bits demarcated between @@ @@
are like reference pointers to which lines where they need to go.

Maybe this is well beyond comprehension to install into RC2, and maybe
even I am using the wrong way to use IDLE.

I am 

> mplayer videofile.avi -idle

(result I am expecting is for the video file to play to the very end,
and the window in which the video was rendered will just stay put
and not close :-)


So, therefore, below this patch, I have demonstrated how I 'patched up'
cfg-mplayer.h (before and after).  The mplayer.c is a little convoluted,
but maybe you can see clearer than I can, and hopefully can show me
the way.  

This was my attempt to apply this patch, before and after:

http://www.myfilestash.com/userfiles/sara22glade/CFG-MPLAYER.H_unmodified.txt



http://www.myfilestash.com/userfiles/sara22glade/MPLAYER.C_checkit.txt


Anything to achieve the effect I am looking for would be graciously accepted. :-) Be well, Sara.
