## Running GStreamer VAAPI Applications

### Environment variables

GStreamer-VAAPI inspects a few of environment variables to define it usage.

`GST_VAAPI_ALL_DRIVERS`. This environment variable can be set, independently of its value, to disable the drivers white list. By default only intel and mesa va drivers are loaded if they are available. The rest are ignored. With this environment variable defined, all the available va drivers are loaded, even if they are deprecated.

`LIBVA_DRIVER_NAME`. This environment variable can be set with the drivers name to load. For example, intel's driver is `i915`, meanwhile mesa is `gallium`.

`LIBVA_DRIVERS_PATH`. This environment variable can be set to a colon-separated list of paths (or a semicolon-separated list on Windows). libva will scan these paths for va drivers.
