Field Documentation

mfxFrameSurface1* AVQSVFramesContext::surfaces

A pointer to a mfxFrameSurface1 struct.

It is available when nb_surfaces is non-zero.

Definition at line 59 of file hwcontext_qsv.h.

int AVQSVFramesContext::nb_surfaces

Number of frames in the pool.

It is 0 for dynamic frame pools or AVHWFramesContext.initial_pool_size for fixed frame pools.

Note only oneVPL GPU runtime 2.9+ can support dynamic frame pools on d3d11va or vaapi

Definition at line 70 of file hwcontext_qsv.h.

int AVQSVFramesContext::frame_type

A combination of MFX_MEMTYPE_* describing the frame pool.

Definition at line 75 of file hwcontext_qsv.h.

mfxFrameInfo* AVQSVFramesContext::info

A pointer to a mfxFrameInfo struct.

It is available when nb_surfaces is 0, all buffers allocated from the pool have the same mfxFrameInfo.
