If the Intel graphics device shows usage on the Video Decode graph, then it is working, at least for some cameras.

Intel hardware acceleration provides substantial savings in both CPU time and power consumption, and is highly recommended if Quick Sync Video is supported by your hardware.Ĭheck Task Manager > Performance tab. Hardware decoding will remain disabled for that camera until you manually re-enable it in Camera Properties > Video tab. The user is not informed when this happens. Sometimes a temporary video decoding error causes Blue Iris to disable hardware accelerated decoding for a camera. Hardware acceleration may make Blue Iris less stable (more likely to crash) on some systems. On Windows 7, hardware acceleration does not work if you run Blue Iris in service mode. In Windows 10 Version 1803+, the Performance tab also provides graphs. Just look in Task Manager on the Processes tab, and you should see a GPU column with a non-zero % load, and the GPU Engine column should read 'GPU X - Video Decode'. On Windows 10 Version 1709+, you can easily verify that hardware acceleration is working. A full app restart is not required when you change individual cameras. You may also override the global hardware decoding option for individual cameras on the Video tab of Camera Properties. Note: If you use sub streams, your CPU usage will likely be low enough that you can ignore this section and run whatever frame rates you want. This max rate setting is supposed to auto-adjust itself upward as necessary, but higher values of this setting directly impact your server's memory usage in a huge way, so don't let it be much higher than the camera's true frame rate. rate' option in camera properties on the Video tab to your camera's actual streaming frame rate, or just barely above. For best efficiency, it is recommended to use frame rates of 15 FPS or lower, as beyond about 15 FPS there is little meaningful improvement in video smoothness compared to the additional processing costs.Īlso set Blue Iris's 'Max. This setting is configured individually for each camera in the camera's web interface. Each frame requires CPU time to process, so the lower the frame rates, the better. In most situations, this is a lot more than you need.

Most cameras have a default frame rate around 25 or 30 FPS.
