New computer and I enabled H265+ and Hardware accelerated decode

[Teeauu]

I had Hardware accelerated decode turned on in V4 and it did a respectable job. I now am on a new computer (I7-8700) and installed V5 at the time as I recall. I went through today and enabled the H265 profile on my cameras. All I can say is I am impressed, 23 cameras between 3 and 5 Mega pixels. The CPU usage dropeed from about 45% to 28% now. Outstanding.

I just picked up an I7-8700 myself. I run between 13-15 cams (some disabled in certain profiles) and I average about 15-20% CPU. Not sure the H265 is doing anything for BI5 at all. I recall seeing somewhere that it wasn't supported? I could be wrong though.

h.265 is supported, its just that hardware acceleration on h265 is not unless you use high power nvidia cards that are inefficient.
265+ is not supported as the variable iframe intervals will screw with motion detection and may also cause tearing in the video.

Cool - good to know. Thank you.

So then if you have the camera set for 265+ does it downgrade the stream to 265?

no, you will have the issues mentioned. It will turn off intel hardware acceleration as its not supported on any variant of h265

Thank you. That I didn't know about 265+.

A general rule. Blue Iris does not make changes to camera setting on the camera.

And I appreciate that
