# VAAPI Plugin
|
|
|
|
## 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 `i965`, 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.
|
|
|
|
**GST_VAAPI_DRM_DEVICE.**
|
|
This environment variable can be set to a specified DRM device when DRM
|
|
display is used, it is ignored when other types of displays are used.
|
|
By default /dev/dri/renderD128 is used for DRM display.
