[xine-user] changing X resolution on the fly

[Florin A. <fl...@an...>]

I am grabbing as much info as i can to build a small dedicated computer
working as a PVR. The output will likely be an NVidia card with a DVI
connector hooked up to an HDTV set.

Nowadays, most HDTV sets accept a variety of different video formats on
their inputs (they do convert almost everything to their only native
format used to drive the display, but that's another story).
Also, recently, the NVidia cards and drivers started to support all
kinds of unusual modes, including interlaced, etc. There are ways to
setup the cards, even under Linux, to use such modes, via custom
modelines in xorg.conf

Now, suppose i put into the xorg.conf modelines for several basic modes
typically used by an HDTV set: 480i, 480p, 720p. Suppose the HDTV set
accepts all of them, and i am able to switch between those modes using
any X mode switching tool.

Question:
Is it possible for xine to actually switch the X mode depending on the
format of the file being played? Say, switch to:
- 480i or 480p for DVD (either i or p depending on whether the DVD is
progressive or interlaced)
- 480i for DVB or other interlaced MPEG2
- 480p for DivX or other "generic" video files which are presumably
deinterlaced already
- 720p when playing HDTV MPEG2 that's in the 720p format
- again 720p when playing 1080i HDTV MPEG2 (and let NVidia deinterlace)
And then, when it exits the full-screen mode, revert back to a "default"
mode.

Or, to refine the question:
- is it possible at all, theoretically, to do that? (i think yes)
- can xine do that currently? (i guess no)
- if it's possible theoretically but it's not done currently, how big of
a change would it be to enable this kind of functionality?
