My question is, can I perform a "Dynamic QP Change" at CQP Encoding Mode, as the similarity of "Dynamic Bitrate Change" in CBR and VBR mode? If I can, how to achieve that?
Hi Joyah,Using CQP mode you can have dynamic change at any frame using regular way of specifiying per-frame QPs: fill mfxEncodeCtrl structure and pass it to EncodeFrameAsync. Here is an excerpt from the Media SDK manual:
The mfxEncodeCtrl structure contains parameters for
per-frame based encoding control.
If nonzero, this value
overwrites the global QP value for the current frame in the constant QP mode.
