Turns out the Intel API for QSV is pretty buggy. There are lots of reports online of random failures and hangs.
I switched us to a different API offered by Windows. It uses the same QuickSync CPU features under the hood, but is better maintained by Microsoft and more stable.
Works really well now, 50% CPU stress reduction when hardware is selected. I’m assuming using the new API does not allow to stream Closed Captions? (CC logo lights up but no text is shown)
Yea same story as the rest of the hardware encoders.
Wow!!! Really happy about this! I knew you would find a fix! Now I can say that my 150$ mini PC from Amazon does make a great DVR server! Works well at home and away!
It even works great at 1080p.
I did a quick test this morning, I will be testing more extensively tonight.
Amazing work Aman. Thanks a lot.
