Hello, I just checked out the latest mplayer svn tree, and it fails to detect vdpau. I have nvidia drivers v185 installed: $ dpkg --get-selections|grep -i vdpau nvidia-180-libvdpau install nvidia-180-libvdpau-dev install nvidia-185-libvdpau install nvidia-185-libvdpau-dev install from configure.log: ########################################## ============ Checking for VDPAU ============ #include <vdpau/vdpau_x11.h> int main(void) { (void) vdp_device_create_x11(0, 0, 0, 0); return VDP_VIDEO_MIXER_FEATURE_HIGH_QUALITY_SCALING_L1; } cc -Wundef -Wdisabled-optimization -Wno-pointer-sign -Wdeclaration-after-statement -std=gnu99 -Wall -Wno-switch -Wpointer-arith -Wredundant-decls -O4 -march=i486 -mtune=generic -pipe -ffast-math -fomit-frame-pointer -I. -D_REENTRANT -I/usr/include/directfb -ffast-math -lncurses -lsmbclient -ldirectfb -lXext -lX11 -lpthread -lXv -o /tmp/mplayer-conf--17056 /tmp/mplayer-conf--17056.c -lvdpau /tmp/mplayer-conf--17056.c: In function 'main': /tmp/mplayer-conf--17056.c:4: error: 'VDP_VIDEO_MIXER_FEATURE_HIGH_QUALITY_SCALING_L1' undeclared (first use in this function) /tmp/mplayer-conf--17056.c:4: error: (Each undeclared identifier is reported only once /tmp/mplayer-conf--17056.c:4: error: for each function it appears in.) Result is: no ########################################## $ grep -i VDP_VIDEO_MIXER_FEATURE_HIGH_QUALITY_SCALING_L1 /usr/include/vdpau/* no matches found. So newer driver is a requirement nowadays?
