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.

Typedef Documentation

§ AVVAAPIDeviceContext

typedef struct AVVAAPIDeviceContext AVVAAPIDeviceContext

VAAPI connection details.

Allocated as AVHWDeviceContext.hwctx

§ AVVAAPIFramesContext

typedef struct AVVAAPIFramesContext AVVAAPIFramesContext

VAAPI-specific data associated with a frame pool.

Allocated as AVHWFramesContext.hwctx.

§ AVVAAPIHWConfig

typedef struct AVVAAPIHWConfig AVVAAPIHWConfig

VAAPI hardware pipeline configuration details.

Allocated with av_hwdevice_hwconfig_alloc().

§ anonymous enum

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.
AV_VAAPI_DRIVER_QUIRK_SURFACE_ATTRIBUTES	The driver does not support surface attributes at all. The surface allocation code will never pass them to surface allocation, and the results of the vaQuerySurfaceAttributes() call will be faked.
