[FFmpeg-devel] [PATCH 3/6] lavfi/qsvvpp: check the parameters before initializing vpp session

[Xiang, Haihao]

From: Haihao Xiang <haihao.xiang@intel.com>

According to the description about MFXVideoVPP_Query [1], we may call
MFXVideoVPP_Query to check the validity of the parameters for vpp
session, use the corrected values to initialize the session.

[FFmpeg-devel] [PATCH 4/6] lavfi/qsvvpp: store a copy of the sequence parameters

[Xiang, Haihao]

From: Haihao Xiang <haihao.xiang@intel.com>

We will postpone the vpp session initialization to when input and output
frames are ready, this copy of the sequence parameters will be used to
initialize vpp session.
