I think the MGA driver supports Xv. At least when I turned on the Xv
display it worked for a bit (although it crashed not too long
afterward).
This is on a G200 with the Matrox HAL driver under Xfree86 4.1.0.
Actually, all three modes worked (to varying degrees) on my system:
Ximages (I guess), Xv, and SDL. The SDL display had some weird issues
with looking really blocky on the bottom 3/4 of the image.
Subtitles don't work at all from what I can tell. I can turn them on
(and if I watch the debug output I see that it found the subtitle
track), but nothing is ever displayed.
The display is unfortunatly jerky. The worst part is, my CPU isn't even
pegged. From what I can tell, vlc reads off a block from the DVD,
de-csses
it, decodes it, sends it to the display plugin, THEN reads off the next
block.
My DVD doesn't seek (or transfer) fast enough for it to keep up[1]. If
vlc
kept some sort of buffer full of blocks, I bet it would be smooth on
even
fairly low end systems.
[1] And this is a 16x DVD using UDMA33 transfers.
