Detailed Description

Member Data Documentation

§ decoder_to_release

IDirectXVideoDecoder* AVDXVA2FramesContext::decoder_to_release

Certain drivers require the decoder to be destroyed before the surfaces.

To allow internally managed pools to work properly in such cases, this field is provided.

If it is non-NULL, libavutil will call IDirectXVideoDecoder_Release() on it just before the internal surface pool is freed.

This is for convenience only. Some code uses other methods to manage the decoder reference.

§ surface_type

DWORD AVDXVA2FramesContext::surface_type

The surface type (e.g.

DXVA2_VideoProcessorRenderTarget or DXVA2_VideoDecoderRenderTarget). Must be set by the caller.

§ surfaces

IDirect3DSurface9** AVDXVA2FramesContext::surfaces

The surface pool.

When an external pool is not provided by the caller, this will be managed (allocated and filled on init, freed on uninit) by libavutil.
