  • Rendering on X11 broken due to wrong dependency from libva-x11.so and libX11.so see intel/media-driver#150 for details. Following command line "sample_decode h264 -foo.264 -r" would fail with -1. Workaround is to symlink correct library Ubuntu: sudo ln -sf /opt/intel/mediasdk/lib64/libva-x11.so.2 /usr/lib/libva-x11.so
    CentOS: sudo ln -sf /opt/intel/mediasdk/lib64/libva-x11.so.2 /usr/lib64/libva-x11.so
