hello
I am trying to use HW encoder for streaming h264. I know i should push raw frames to encoder and it will do everything for me.
Besides that i am expecting that encoder should compare new coming frame with several previous frames for making P-frame difference calculation. And i expect that frame comparation is probably very heavy task.
What if i know exactly update region? I know list of affected regions which changed relative to previous frames. This info theoretically could help encoder to do frame comparation faster. Knowledge of frame update region could save some CPU/GPU power.
But question is: how to give update region to encoder? Is it ever possible?
