A VAAPI backend driver for NVIDIA Tegra SoC's, based on multimedia units accessed through Host1x. This driver is experimental, don't expect it to work in every situation.

Currently supported features:

• NV12 to RGB colorspace conversion
• MPEG2 decoding
• H264 decoding (very experimental, known issues)
• X11/DRI2 surface presentation

Currently supported SoC's:

• Tegra210
• Tegra186
• Tegra194

• C++14-capable compiler
• libva headers
• libdrm headers
• Kernel with new TegraDRM UAPI support (v5.15 or newer) and NVDEC support (only in linux-next at time of writing)

Building:

mkdir build
cd build
cmake ..
make

Testing:

export LIBVA_DRIVERS_PATH=<build directory>
export LIBVA_DRIVER_NAME=tegra

mpv --hwdec=vaapi-copy --hwdec-codecs=all video.m2v
