Running GStreamer VAAPI ApplicationsRunning GStreamer VAAPI Applications — How to run GStreamer application with VAAPI elements. |
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.
