Re: [xine-devel] GTK visual type?

[Andres S. <dil...@vo...>]

That's too bad, I spoke to daniel (f1rmb) on IRC about it, and started work
on video_out_gtk.c.  I like the idea of having sinek rely on gtk instead of
X, so it can be run under whatever they port gdk to (win32, fb, x,
directfb) without me having to code explicit checks into sinek.  Does
anyone see problems with this type of implementation?  The issue of
hardware acceleration (or lack thereof) came up; I'm not sure that it's
an issue, as the gdk port should be handling it.  However, certain types
of hardware (yuv2rgb hardware support, and so on) will probably require 
knowledge from the application to use it, unless gtk either offers this
functionality, or provides a way to query the video hardware
capabilities,  and use some sort of ioctl-ish style interface to speak
to the hardware.  This would be something to take up w/ the gtk folks.

And, on the topic of yuv2rgb, video_out_gtk initializes the
yuv2rgv_factory with a hardcoded mode of 24 bit RGB.  GDK has code that
converts RGB pixels to the type used by the video device (gdk/x11/gdk*
has a lot of code similar to video_out_xshm.c).  I'm assuming that this
will be a performance hit (yuv -> 24 bit rgb -> X bit rgb, instead of yuv -> X bit rgb directly), but I won't know how much until I get this thing working
properly.  Anyone have comments/input?

To those celebrating it, happy new years :)

It's not denial.  I'm just selective about the reality I accept.
