Hi, VA_DRIVER_INIT_FUNC is generated from the configure script. So, if you have a current libva stack, with the associated pkg-config files, then it will work out of the box. the This machinery was useful in the past to maintain binary compatibility with older/newer libva versions than vdpau-video was built for. I will probably drop support for any VA-API < 0.32.0. VA_DRIVER_INIT_FUNC in my setup doesn't contain the version number. I suspect the problem is that I'm not installing libva into system locations, and vdpau-driver's configure script is getting confused. To repro: - ensure there's no /usr/include/va/va_version.h or similarly located installation - install libva into $HOME: git clone git://anongit.freedesktop.org/libva cd libva ./autogen.sh && ./configure --prefix=$HOME/apps/libva && make -j32 && make install - install vdpau-driver into $HOME: git clone git://anongit.freedesktop.org/vaapi/vdpau-driver cd vdpau-driver export LIBVA_DRIVERS_PATH=$HOME/apps/libva/lib/dri LIBVA_X11_DEPS_CFLAGS=-I$HOME/apps/libva/include LIBVA_X11_DEPS_LIBS=-L$HOME/apps/libva/lib LIBVA_DEPS_CFLAGS=-I$HOME/apps/libva/include LIBVA_DEPS_LIBS=-L$HOME/apps/libva/lib ; ./autogen.sh && ./configure --prefix=$HOME/apps/va --enable-debug && find . -name Makefile |xargs sed -i 'sI/usr/lib/xorg/modules/driversI$HOME/apps/libva/lib/driIg' && make -j32 && make install The resulting nvidia_drv_video.so file doesn't have the _0_33 function. |

vdpau_driver.c includes a __vaDriverInit_0_31(), but the current LIBVA_MINOR_VERSION is 33, not 31, causing libva to fail to load vdpau-driver. Adding the below trampoline seems to make everything work: VAStatus __vaDriverInit_0_33(void *ctx) { return vdpau_Initialize_Current(ctx); }
