Subject: [MPlayer-users] SVGA locking - workaround


[Automatic answer: RTFM (read DOCS, FAQ), also read DOCS/bugreports.html]
The SVGA-locking-the-console bug (see earlier thread with lots of posts from me)
was annoying me so much that I had a look at what was going on.  It seems that
the getch2 functions aren't necessary for -vo svga, and when they are used,
the calls to the vga_ functions (which change the console's text-handling
themselves) combined with the getch2_dis/enable functions mess up the console so
that is has to be reset.

I've come up with a way around this - I've disabled the call to getch2_enable
when -vo is svga - using this patch:

It's almost certainly not the right way of doing things, but it stops the
problem until a proper fix can be done.

It also prevents the console from becoming frozen when mplayer isn't running as
root, because normally it would exit with
  svgalib: Cannot get I/O permissions 
and never call uninit(), but with this change applied, failing to call uninit
doesn't cause any permanent damage.

Is this fix some use, or am I just wasting your time?

Can I buy a drink here, or are you just going to throw limes at me?
