Detailed Description

An API-specific header for AV_HWDEVICE_TYPE_D3D11VA.

The default pool implementation will be fixed-size if initial_pool_size is set (and allocate elements from an array texture). Otherwise it will allocate individual textures. Be aware that decoding requires a single array texture.

Using sw_format==AV_PIX_FMT_YUV420P has special semantics, and maps to DXGI_FORMAT_420_OPAQUE. av_hwframe_transfer_data() is not supported for this format. Refer to MSDN for details.

av_hwdevice_ctx_create() for this device type supports a key named "debug" for the AVDictionary entry. If this is set to any value, the device creation code will try to load various supported D3D debugging layers.
