RV635 PRO chipset. PCIE x16 and AGP bus interfaces. How much video RAM? 256? 512? 1024? The man page for radeon doesn't explicitly mention your model number, but it does claim to support your chipset. Have you read the man page radeon(4)? It lists all the options. Perhaps playing with some of them will improve your performance. >> Let's concentrate on mplayer.

Have you tried a more recent video driver? I haven't asked yet, what version of fedora, and what version of xorg_x11_drv_ati? I'm running F14 w/ xorg-x11-drv-ati-6.13.1-0.3.20100705git37b348059.fc14.x86_64 > gl_nosw: pixelation, but no DRI failure message > dga: mess > fbdev: cannot open /dev/fb, no video > xvidix: pci errors, no video > x11: DRI failure, pixelation Without some sort of hardware support, 3D is going to require a really fast CPU. What is the processor in your system? 32 or 64 bit? Any idea what the system bus is running at? My laptop has an Intel Core2 T7200 @ 2.0GHz. With my video card, HD is iffy at best (playing a local small mpg4 file really drags and has trouble keeping up with the audio). I have no problems with Flash videos, though the quality can vary greatly between clips (the less the quality of the pics, the better the video plays, go figure. B^) Flash is supposed to realize when the processing starts to drag and start dropping video frames to try and keep up with the audio. At least that's my understanding. I usually play Flash with my browser, and mpegs and avis with mplayer. Also, I have the Adobe Flash Square driver installed for x86_64. It has its drawbacks (like the memcpy bug that needs working around in Firefox). You might also be able to play Flash directly with Google Chrome. I'm not up on what mplayer's flash video support uses. > dga: mess: > Movie-Aspect is undefined - no prescaling applied. > VO: [dga] 640x480 => 640x480 BGRA vo_dga: DGA 2.0 available :-) Can switch resolution AND depth! > vo_dga: Selected hardware mode 640 x 480 @ 59 Hz @ depth 24, bitspp 32. > vo_dga: Video parameters by codec: 640 x 480, depth 24, bitspp 32. > vo_dga: Framebuffer mapping failed!!! > FATAL: Cannot initialize video driver. > Too many buffered pts Hmmm. I googled DGA Video, and I found the following snippets on the first page that came up: > WHAT IS DGA. DGA is short for Direct Graphics Access and is a means for a program to bypass the X server and directly modifying the framebuffer memory. > However DGA has some drawbacks. It seems it is somewhat dependent on the graphics chip you use and on the implementation of the X server's video driver that controls this chip. So it does not work on every system... > You should also try if the -vo sdl:driver=dga option works for you! It's much faster! Looks like YMMV. I tried running my videos with DGA, and I found that I have no support for it installed. I was looking at my X11 packages, and I have the following installed related to xv: libXv, libXvMC, libxvidcore4, xorg-x11-server-Xvfb, xv, and xvidcore > I should have mentioned this before: > The degree of pixelation is not constant. > The longer I play the worse it gets. > Rebooting doesn't help. > Sometimes waiting a week does. > Pixelation comes in spurts. > I'm in the middle of a spurt that was > preceeded by a long period of good video. Usually a sign that you're CPU starved when playing video. You really want to find a way to leverage your video card with a better video output method. I've been happy with Xv for the most part, but I *really* like my new GeForce GT218 card in my desktop. Using VDPAU in MythTV, it plays HD TV like my real HD television. No more pixelation, no more stuttering. Of course, that doesn't help my laptop where I'm stuck with this ATI video. B^) -- Kevin J.
