Does > anyone have a reference to the Xv support by driver? 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. -- \ |_ _|__ __|_ \ __| Jason Andresen jandrese@mitre.org |\/ | | | / _| Network and Distributed Systems Engineer _| _|___| _| _|_\___| Office: 703-883-7755 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
