ID3D11Texture2D* AVD3D11VAFramesContext::texture

The canonical texture used for pool allocation. If this is set to NULL on init, the hwframes implementation will allocate and set an array texture if initial_pool_size > 0.

The only situation when the API user should set this is:

• the user wants to do manual pool allocation (setting AVHWFramesContext.pool), instead of letting AVHWFramesContext allocate the pool
• of an array texture
• and wants it to use it for decoding
• this has to be done before calling av_hwframe_ctx_init()

Deallocating the AVHWFramesContext will always release this interface, and it does not matter whether it was user-allocated.

This is in particular used by the libavcodec D3D11VA hwaccel, which requires a single array texture. It will create ID3D11VideoDecoderOutputView objects for each array texture element on decoder initialization.

BindFlags

UINT AVD3D11VAFramesContext::BindFlags

D3D11_TEXTURE2D_DESC.BindFlags used for texture creation. The user must at least set D3D11_BIND_DECODER if the frames context is to be used for video decoding. This field is ignored/invalid if a user-allocated texture is provided.

MiscFlags

UINT AVD3D11VAFramesContext::MiscFlags

D3D11_TEXTURE2D_DESC.MiscFlags used for texture creation. This field is ignored/invalid if a user-allocated texture is provided.
