 The container requires host NVIDIA GPU driver versions of at least **450.80.02**, with the corresponding container toolkit runtime to be also configured on the host for allocating GPUs. All Maxwell or later generation GPUs in the consumer, professional, or datacenter lineups will not have significant issues running this container, although the selkies-gstreamer high performance NVENC backend may not be available (see the next paragraph). Kepler GPUs are untested and likely does not support the NVENC backend, but can be mostly functional using the software acceleration fallback.
 
-The high performance NVENC backend for the selkies-gstreamer WebRTC interface is only supported in GPUs that is listed as supporting `H.264 (AVCHD)` under the `NVENC - Encoding` section of NVIDIA's [Video Encode and Decode GPU Support Matrix](https://developer.nvidia.com/video-encode-and-decode-gpu-support-matrix-new). If your GPU is not listed as supporting `H.264 (AVCHD)`, add the environment variable `WEBRTC_ENCODER` with the value `x264enc` in your container configuration for falling back to software acceleration, which also has a very good performance depending on your CPU.

 The username is `user` in both the container user account and the web authentication prompt. The environment variable `PASSWD` is the password of the container user account, and `BASIC_AUTH_PASSWORD` is the password for the HTML5 interface authentication prompt. If `ENABLE_BASIC_AUTH` is set to `true` for selkies-gstreamer (not required for noVNC) but `BASIC_AUTH_PASSWORD` is unspecified, the HTML5 interface password will default to `PASSWD`.
 > NOTES: Only one web browser can be connected at a time with the selkies-gstreamer WebRTC interface. If the signaling connection works, but the WebRTC connection fails, read the [Using a TURN Server](#using-a-turn-server) section.
