Detailed Description

API-specific header for AV_HWDEVICE_TYPE_VAAPI.

Dynamic frame pools are supported, but note that any pool used as a render target is required to be of fixed size in order to be be usable as an argument to vaCreateContext().

For user-allocated pools, AVHWFramesContext.pool must return AVBufferRefs with the data pointer set to a VASurfaceID.

Enumeration Type Documentation

anonymous enum

Enumerator
AV_VAAPI_DRIVER_QUIRK_USER_SET	The quirks field has been set by the user and should not be detected automatically by av_hwdevice_ctx_init().
AV_VAAPI_DRIVER_QUIRK_RENDER_PARAM_BUFFERS	The driver does not destroy parameter buffers when they are used by vaRenderPicture(). Additional code will be required to destroy them separately afterwards.
AV_VAAPI_DRIVER_QUIRK_ATTRIB_MEMTYPE	The driver does not support the VASurfaceAttribMemoryType attribute, so the surface allocation code will not try to use it.
