[HEADS UP/CFT] Xserver 1.6: testing XvMC HOWTO

[Marcin Cieslak]

A short how-to:

1) Compile and configure Xserver 1.6 with xf86-video-intel driver 2.6.1

2) Add

         Option          "XvMC"                  "on"

to your /etc/X11/xorg.conf in the Section "Device" for the "intel" driver:

Section "Device"
         Identifier  "Intel945"
         Driver      "intel"
         VendorName  "Intel Corporation"
         BoardName   "Mobile 945GM/GMS, 943/940GML Express Integrated 
Graphics Controller"
         (...)
         Option          "XvMC"                  "on"
EndSection

3) Add two flags to your ports/multimedia/mplayer/Makefile, so it looks 
more or less like this:

CONFIGURE_ARGS+=        --disable-ssse3 \
                         --disable-directfb \
                         --disable-faac \
                         --disable-twolame \
                         --disable-mencoder \
                         --enable-xvmc \
                         --with-xvmclib=XvMCW

4) Verify that /usr/local/lib/libXvMCW.so is installed (should be 
required by the intel driver).

5) Recompile mplayer and reinstall

6) Get a pure MPEG-2 video stream (MPEG-2 TS for example)

7) Play it with:

OSD does not work, and I probably don't have IDCT but other than that it 
seems to work, from -msglevel vo=9 output:
