lavu/pixfmt: Update the description for AV_PIX_FMT_QSV
Since D3D11 was introduced for QSV in FFmpeg 5.0, there is an implied API/ABI change for user-supplied frames [1], hence update the description for AV_PIX_FMT_QSV. [1] https://ffmpeg.org/pipermail/ffmpeg-devel/2021-December/290444.html Signed-off-by: Haihao Xiang <haihao.xiang@intel.com>

* 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.
