Re: [mythtv-users] HDTV performance in 0.18
Darn, I compiled without "-–enable-opengl-vsync". Can I gain a lot of cpu by recompiling? I have confirmed that GLX is loading (from xorg.0.log): (II) LoadModule: "glx" (II) Loading /usr/X11R6/lib/modules/extensions/libglx.so (II) Module glx: vendor="NVIDIA Corporation" (II) Loading extension GLX (II) Loading extension NV-GLX (II) Initializing extension GLX CPU is fine except when I record two DTV programs, and watch a third. I have disabled xvmc and enabled kernel deinterlacing to reduce combing. Video/audio is fine, but I'm concerned about intermittent frame drops during the recordings.

Re: [mythtv-users] HDTV performance in 0.18
I was always concerned about this, and I'm not sure I did it correctly right. I did let ./configure run without arch arguments, but it "seemed" to do the right thing (which it should be able to do?): CFLAGS = -pipe -march=pentiumpro -Wall -W -O3 -Wall -Wno-switch -fomit-frame-pointer -Wno-missing-prototypes -D_REENTRANT -DPIC -fPIC -DMMX -DUSING_IVTV -DUSING_XRANDR -DUSING_XVMC -DUSING_OPENGL_VSYNC -D_GNU_SOURCE -D_FILE_OFFSET_BITS=64 -DPREFIX=\"/usr/local\" I say this because of the manual line on the subject: -march=pentiumpro -mmmx for the AMD Athlon XP CPU with MMX, 3dNOW!, enhanced 3dNOW! and SSE. (pentium3 compatible) That makes it sound like the result is correct. But of course, -DMMX and -mmmx are different... should I be seeing both? What do you put in your ./configure arguments, if you're building for an Athlon XP 3000+?

Other things like making sure AGP 4x or 8x is enabled, and the having latest Nvidia drivers make a big diff. I was getting horrendous HD performance with 7167, and 7174 improved the situation quite a bit. Also, RenderAccel seems to cause problems in some situations, but that's hard to qualify. You can check some of this stuff by doing a 'cat /proc/drivers/nvidia/agp/status' to see what the system thinks of the agp status, and also 'glxinfo' which will detail dri and glx info. Sometimes you think one thing, but the system thinks another. I've got an amd64 3000 with 512 and a 5200 and I get passable (~85% cpu decoding 1920x1080i without deint) performance. I'm watching for the fixes to XvMC with breathless anticipation. ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

[mythtv-users] HDTV performance in 0.18
Does anyone find it strange to not have enough horsepower to render HDTV in 0.18 on an Athlon XP 3000+ with 1GB of RAM? (Caveat: this is rendering to 800x600 24-bit S-Video on an fx5200.)
