Comment (by lizhong1008):
Please comment why you need such an option. Not everything of MSDK should
be exposed in ffmpeg.
I guess the option "userawref" here you mean is to use original input yuv
frame as reference during encoding, instead of using reconstruct frame as
reference.
But what is the benefit? It will cause decoder behavior doesn't match
encoder, then produce bad decoded video quality.
