NVDEC chips on NVIDIA GPUs provide accelerated hardware-based video decoding. This helps to reduce the load on the CPU and/or increase the number of the video cameras displayed on the Client.

Attention!

In C-Werk, the NVDEC chips are used to decode:

  1. Video in the H.264, H.265 and MPEG-2 formats.
  2. Live mode, Archive mode (forward playback only) and TimeCompressor mode.

Attention!

Before you start, make sure to install the latest driver for your NVIDIA GPU.

Note

A list of the devices that support decoding with NVDEC chips, see on the NVIDIA official website.

Note

When decoding with NVIDIA NVDEC chips on portable computers due to the specifics of the devices interaction, the resources of the built-in graphics card will also be used.

When decoding with NVDEC chips, the following limitations apply:

  1. Maximum video resolution for the H.264 format is 4096x4096.
  2. Maximum video resolution for the H.265 format is 8192x8192.
  3. The maximum total frame rate per second for the H.264 format is 648 FPS.

To enable decoding with NVDEC chips, do the following:

  1. In C-Werk, go to Settings → Options (1) → User Interface (2). 

  2. Set the Enable hardware decoding checkbox (3).
  3. Click the Apply button.

Decoding with NVDEC chips is enabled.
