General information about the PureVideo/CUDA hardware acceleration

You can enable the PureVideo/CUDA hardware acceleration when video signals from IP devices are decompressed. In this case, the GPU of the video card can perform decompression, which reduces the load on the server CPU.

Note

For more information about the PureVideo/CUDA hardware acceleration, see the official NVIDIA reference documentation.

Limitations of using the PureVideo/CUDA hardware acceleration

  1. Use Windows 10 and later, which operates with NVIDIA GPUs, as well as related libraries and drivers, such as the CUDA Toolkit and NVIDIA Video Codec SDK.
  2. Video card with NVDEC hardware decoding support is installed.

    Attention!

    • CUDA is compatible with generations of computers on architectures: Kepler (partially), Maxwell, Pascal, Volta, Turing, Ampere, and Ada Lovelace (partially) (see CUDA).
    • You can check the version of your GPU Compute Capability on the manufacturer's website.
    • When you use the NVIDIA GPU, we recommend installing the latest driver version from the official website.
  3. You can use it only for one video card.
  4. You can use it for decompression of live video on the client.
  5. You can use it for decompression of video signals with H.264 and H.265 compression formats.
  6. You can use it for decompression at any resolution of the camera.

You can enable the PureVideo/CUDA hardware acceleration on the settings panel of the Camera object or on the settings panel of the Monitor object on the List of cameras tab (see Selecting and configuring video cameras and Selecting and configuring video cameras in bulk).

Enabling PureVideo/CUDA in the settings of the Camera object

To enable the PureVideo/CUDA hardware acceleration in the settings of the Camera object, do the following:

  1. Shutdown Axxon PSIM if it is running on the computer.
  2. Set the 1 value for the EnableCodecSettings registry key (see Registry keys reference guide. For more information on working with the registry, see Working with Windows OS registry). The key opens the Decompressor and Compressor settings for editing.
  3. Go to the Advanced settings tab on the settings panel of the Camera object.

  4. From the Decompressor drop-down list, select the Nvidia decoder value.
  5. Click the Apply button.
  6. Restart Axxon PSIM.

Enabling The PureVideo/CUDA hardware acceleration is complete.
