Enabling cl_intel_va_api_media_sharing extension

  1. Download sources:

Example:

git clone https://anongit.freedesktop.org/git/mesa/drm.git libdrm
git clone https://github.com/intel/libva.git libva
  1. Compile and install libdrm

Example:

cd libdrm
./autogen.sh
make -j `nproc`
sudo make install
  1. Compile and install libva

Example:

cd libva
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
./autogen.sh
make -j `nproc`
sudo make install
  1. During Neo compilation verify libva was discovered
