Hi Bernhard,
I tried to compile MythTV with VDPAU support and it gave me the following error:
util-vdpau.cpp: In member function 'void VDPAUContext::PrepareVideo(VideoFrame*, QRect, QRect, QSize, FrameScanType)': util-vdpau.cpp:1092: error: call of overloaded 'abs(long long int)' is ambiguous /usr/include/stdlib.h:83: note: candidates are: int abs(int) /usr/include/c++/4.2/cstdlib:143: note: long int std::abs(long int) gmake[2]: *** [util-vdpau.o] Error 1 gmake[2]: Leaving directory `/usr/ports/multimedia/mythtv/work/mythtv-0.22/libs/libmythtv' gmake[1]: *** [sub-libmythtv-all] Error 2 gmake[1]: Leaving directory `/usr/ports/multimedia/mythtv/work/mythtv-0.22/libs' gmake: *** [sub-libs-all-ordered] Error 2 *** Error code 1
I was able to fix the problem, just replace function 'abs' to 'llabs'. After that fix it compiles and work with my nVidia Silent GeForce 8400 GS 512MB. It used only 5-6% of my CPU when I played 1080p movie.
That sounds great but i do not have any nVidia hardware so i cannot test it myself. What configure options did you exactly add? From the VDPAU wiki page it looks like it would be a good idea to add both: --enable-xvmc-opengl --enable-vdpau
I hope to have some time in the upcoming days to prepare a test port for this and will reply when i'm ready.
As a side note i've seen that MythTV is already preparing a 0.23 release so I want to have a 0.23 port ready for a Call for Testers when they announce their first release candidate.
