pub const AV_PIX_FMT_QSV: i32 = 114;Expand description
HW acceleration through QSV, data[3] contains a pointer to the mfxFrameSurface1 structure.
Before FFmpeg 5.0: mfxFrameSurface1.Data.MemId contains a pointer when importing the following frames as QSV frames:
VAAPI: mfxFrameSurface1.Data.MemId contains a pointer to VASurfaceID
DXVA2: mfxFrameSurface1.Data.MemId contains a pointer to IDirect3DSurface9
FFmpeg 5.0 and above: mfxFrameSurface1.Data.MemId contains a pointer to the mfxHDLPair structure when importing the following frames as QSV frames:
VAAPI: mfxHDLPair.first contains a VASurfaceID pointer. mfxHDLPair.second is always MFX_INFINITE.
DXVA2: mfxHDLPair.first contains IDirect3DSurface9 pointer. mfxHDLPair.second is always MFX_INFINITE.
D3D11: mfxHDLPair.first contains a ID3D11Texture2D pointer. mfxHDLPair.second contains the texture array index of the frame if the ID3D11Texture2D is an array texture, or always MFX_INFINITE if it is a normal texture.
