4.2.8 - January 7, 2016 - Hardware Acceleration

[bp2008]

Hmm. Maybe the re-encoding part is taking up such an overwhelming amount of CPU that the decoding efficiency gain isn't seen? Or more likely the hardware decoder isn't activating unless direct to disk is enabled...

 

[bp2008]

I overhauled my camera settings, and built a spreadsheet to help me keep track of how I have them all set.



CPU usage is now bouncing between 14 and 22%, usually around 16-20%. I guess I didn't aim high enough.

@bp2008, have you tried running gpu-z to check the load on the graphics?

 

[bp2008]

I feel like some of my motion masks have disappeared since updating... anyone else?

Nope. I didn't know you could even do that with Intel graphics.

Nope. I didn't know you could even do that with Intel graphics.

Did you change the res on any of your cams? That will remove the masks.

 

[bp2008]

Hmm. On one, temporarily. But all of my 1920x1080 cams are being seen as 1920x1088 when hardware decoding is enabled on them. THAT may have done it. I already reported the resolution mismatch to Ken by email.

sounds like you nailed it!

GPU-Z info in this screenshot. I stopped Blue Iris briefly there in the middle, to prove that it was Blue Iris causing the utilization.

 

[fenderman]

@bp2008, That is great. Shows that there lots of processing power still available in the gpu. Interesting to see that your processor is pulling about 10w less than before due to the lower consumption. GPU is only using 1, if its accurate..

Great to see these changes working! I'd love to be able to get the benefit as my CPU usage hovers around the low 80% region, but I have Nvidia graphics.

I did try changing from the video card to onboard (CPU is i7-4790), but usage sits at high 90% range with hardware accel on or off.

Fingers crossed for Nvidia support.

If you are using the onboard graphics you should see the change. Are you recording direct to disk? Did you restart blue iris after you made the changes? Try rebooting the pc.
Did you indicate integrated graphics in the bios and completely remove the nvidia card?
How many cams and what res are you running where you see 80 percent cpu? How much memory do you have?

Yes, I'm using DTD continuous recording, did restart BI, and try restarting the PC.

I didn't remove the Nvidia card, but I disabled it in BIOS, enabled onboard graphics, and plugged the HDMI cable into the motherboard socket rather than the graphics card.

16 cams: 11 @ 1080, 3 @ 720, 2 @ 2048x1536. These all run 20 or 25 FPS. (there are another 4 @ 160x128 7 fps used just for audio).

PC has 16GB RAM. Limit preview rate set to 15fps. Nothing else running on the machine.

did you enable hardware acceleration in blue iris options>cameras ?

 

[wcrowder]

Sweet!!!!

 

[Warsaws]

I may be having the strangest experience of all so far. My CPU has always hovered around 25%. When I enable hardware acceleration, the CPU goes to about 50% average, but is jumping all over the place between 48-70%

Yep, then restarted etc.

did you restart?

 

[fenderman]

Just tested another pc...dropped from 30-32 to 20-22...

 

[wcrowder]

So much for that idea.

I installed.

It works, CPU usage down from 35-41% to 11-15%! The trick is, after enabling hardware acceleration, you need to close Blue Iris (stop the service if necessary) and start it again.

It's working. @fenderman, I'm pretty happy I took your advice and stuck with the on board 4600. I've dropped below 20% on an E3-1225v3.

Most people should wait for a version before updating, it does have some flaws with the update and some compatibility issues.

Thanks everybody for the help.
Bill.

Absolutely I restarted. If only it were that simple.
