[xine-devel] [patch] refresh rate based modeline selection

[Renaud <rg...@fr...>]

The following patch enables automatic selection of the best modeline for 
fullscreen playback based on its refresh rate, not only its resolution (see 
my previous post).

It's only a proof of concept and needs improvement, because I had to hardcode 
the video's refresh rate in it :( (I took 29.97fps, NTSC).

Eventually, it should be possible to create new modelines on the fly using 
XF86VidModeModModeLine(), thus removing the need for the user to define them 
by hand in XF86Config. And XF86VidModeValidateModeLine() is here to prevent 
us from blowing up his/her monitor :)

From what I gathered by reading xine's source, the best way to get the video 
stream's frame rate would be get_video_rate() in metronom.h, but I suppose 
this requires a stream to be currently playing.
This means we must either use a default refresh rate value when switching to 
fullscreen while no stream is playing, or to only allow fullscreen mode 
during playback.

I've only just started to dive into xine and I don't know the code enough to 
make that kind of changes, so sorry if this patch/this post are not the 
correct way of doing things :)

Renaud.
