BI Using near 100% cpu

[aviondubzz]

I have just purchased a dedicated pc just for blueiris and recording. I have only added 3 cameras so far and everything is lagging and it says 99% CPU usage. I believe my pc should be more than capable of handling the tasks.

Yes - you are right it should be able to handle it. Have you reviewed the wiki for all the performance tweaks you will need to do? Lots of good detail, you just need to dig a little.

Thanks for the quick reply, checking that now!

Can I select the hardware accelerated decode per camera individually instead of from the overall camera settings? Reason being is that my wyze cams had dropped when i changed the overall hardware accelerated decode.

I would guess you need to ENABLE Direct to Disc for each camera.

 

[aviondubzz]

Yes I have done that for each camera but there seems to be a separate option for hardware accelerated decode.

You can change the setting on the drop down in your screenshot to "No" for your wyze cams.

Something is very wrong with your set up because even without hardwood coding you would be nowhere near 100.

It seems once I started to change all cams to direct to disk, the cpu usage dropped drastically. Down to 25% now... EDIT 35% now

Great thanks. I also need some help with my wyze cams but I will create a new thread in the proper area for that.

Sounds better. If you follow the optimizing @mikeynags linked to you should be ok.

You can reduce it into the single digits if you
Use the sub stream function see wiki

 

[aviondubzz]

Yes I added substream to some of them since the others I need to be able to see higher quality during live viewing. Thanks!

When you open the window to full screen it will show The main stream
