If your configuration supports XVideo and you do not opt to use GL, then
Xtheater will automatically use XVideo for all playback. This
provides nice fast, nicely interpolated scaling, allowing one to avoid the
unpleasantness of a VidMode switch without horrible frame loss, redraw
XFree86 4.0.x, 4.0.3 recommended, included with RedHat 7.1, for one example.
Supported Video Card:
Intel i810 and i815 - These Supposedly support XVideo out of the box
with XFree 4.0.x.
Matrox Gx00 chipsets - From what I hear, generally support XVideo
with XFree86 4.0.x out of the box, but I have no way to verify this.
nVidia chipsets - Supposed to support XVideo with their provided
binary drivers, but this also I have no way
of verifying myself.
ATI Radeon, Rage128 and Mach64 - I have heard people to say have some
XVideo support, but again I cannot verify this. You may need to get drivers
from the GATOS project. Also,
the DRI project may have useful
files for some ATI chipsets, but I have no personal experience with this.
3Dfx Voodoo Banshee/3/4/5 - I have heard work with 4.0.3 and above,
but I know for a fact that 4.0.3 does *not* work out of the box. A newer
version of the DRI is needed from the
DRI project homepage. I use 0.7
myself. The Extras and tdfx downloads are of interest here.
Other Chipsets - I have no information on other chipsets, but
if they are supported and you know it, let me know.
If you can not get the XVideo extension to work with your card, but
can have support for hardware OpenGL or Mesa 3D support (i.e. Sun 3D chipsets
under Solaris 8), then the GL support for MPEG playback
may be of interest.
