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+?
I used:
./configure --enable-xvmc --enable-opengl-vsync --enable-directfb

MythTV is often compiled with no support for MMX or anything more than pentium pro optimization. If you didn't enable processor specific optimization and mmx, and opengl when doing a ./configure then this could have the bad effect. I haven't noticed much if any CPU change between .17 and .18 (Granted I run out of CVS) so I'd check that first.

(Caveat: this is rendering to 800x600 24-bit S-Video on an fx5200.) XV and OpenGL work, renderaccel is true, AGP functional, and by the way, xine can play HDTV with Xv no problem.
I'm using libmpeg2 and suid/realtime, and the system can just _barely_ handle it without deinterlacing. It's pegged at 95% CPU, and still drops occasional frames. If I turn on deinterlacing, then it's real bad, dropping frames every few seconds.
As before, toggling libmpeg, realtime, and opengl appear to have zero effect on performance, despite log output from the frontend suggesting they're working.
I keep finding references to people who are doing HDTV with 2100's and 2400's and so forth. I wonder what the difference is - rendering to a different screen resolution or color depth perhaps?
Saving grace is that in 0.18 XvMC finally works, almost. I still get ugly flicker and stutter from the OSD, and so far am averaging about 1 hard-lock (reboot required) per day... A major improvement.
