Hi Juergen:

Well I got a little bit further, but still no hardware acceleration.  I 
had to install libva-vdpau-driver, for some reason it was not installed. 
Shouldn't it have been installed by one of the other ports?  Maybe I am 
missing some other port that I need?  So now I have:

# vainfo
libva info: VA-API version 0.33.0
libva info: va_getDriverName() returns 0
libva info: Trying to open /usr/local/lib/va/nvidia_drv_video.so
libva info: Found init function __vaDriverInit_0_33
libva info: va_openDriver() returns 0
vainfo: VA-API version: 0.33 (libva 1.1.0)
vainfo: Driver version: Splitted-Desktop Systems VDPAU backend for VA-API 
- 0.7.4
vainfo: Supported profile and entrypoints
       VAProfileMPEG2Simple            :	VAEntrypointVLD
       VAProfileMPEG2Main              :	VAEntrypointVLD
       VAProfileMPEG4Simple            :	VAEntrypointVLD
       VAProfileMPEG4AdvancedSimple    :	VAEntrypointVLD
       VAProfileH264Main               :	VAEntrypointVLD
       VAProfileH264High               :	VAEntrypointVLD
       VAProfileVC1Simple              :	VAEntrypointVLD
       VAProfileVC1Main                :	VAEntrypointVLD
       VAProfileVC1Advanced            :	VAEntrypointVLD


But when I run vlc I do not see hardware acceleration.

I recompiled
ffmpeg1-1.0.1
libva
libva-vdpau-driver
with GCC, but it still doesn't work.  Giving up for now.  Has anyone got 
it working with world and ports compiled with clang?
