Intel Quick Sync Video (QSV) is a technology available on some Intel processors, that provides hardware acceleration for video encoding and decoding. QSV provides faster and more energy efficient processing of video content.

Axxon One applies Intel QSV for decoding:

  1. Video formats: H.264, H.265 and H.265+.

  2. Live mode, Archive mode (forward playback only) and TimeCompressor mode.


If the Client shares the same PC with the Server, which applies a detection tool to а video stream, Intel Quick Sync Video will not be used for displaying this stream.


Maximum pixel resolution depends on your particular version of the Intel Quick Sync core. For details, refer to https://www.intel.com/content/www/us/en/homepage.html.

To use Intel Quick Sync Video, make sure your system meets the following requirements:

  1. The CPU should have an integrated graphics core with Intel Quick Sync Video support.

    You can check if the CPU supports QSV here. 


    For H.265 and H.265+ video formats, Intel Quick Sync Video technology is supported only on Intel processors with microarchitecture: Braswell (only decoding), Cherry Trail (only decoding), Skylake, Apollo Lake, Kaby Lake, Gemini, Coffee Lake and newer microarchitecture.


  2. The mainboard supports the GPU core (includes Flexible Display Interface). 

  3. The graphics driver supports QSV. We recommend using the latest version of the Intel HD Graphics Driver.

    You can also update the driver automatically using the Intel Driver Update Utility.


To activate the Intel QSV in Axxon One you need to:

  1. Enable using the integrated graphics core in the BIOS settings. 

    Depending on the BIOS version, it may be named differently (iGPU, Internal Graphics, Integrated Graphics Adapter − PEG).


  2. It is not allowed to use an integrated graphics core and an external graphics card at the same time. In this case, to use Intel QSV, do as follows:
    1. enable Multi-Monitor in the BIOS settings;

    2. In Windows OS connect a virtual monitor to the integrated graphics core and extend the desktop to it.

  3. Go to Settings → Options → User Interface (1-2) in Axxon One. 
  4. Select the Enable hardware decoding checkbox (3).
  5. Click the Apply button.
