    When using NVIDIA NVENC hardware with older graphics drivers in your transcoding setup, you may notice that visual artifacts or reduced quality may appear every few seconds in the transcoded stream frames. This may be more noticeable on lower bitrate output renditions. This occurs because the default settings for the NVENC encoder constrain the keyframe bitrate so that the keyframe quality is reduced.

    Updating the graphics driver for your NVIDIA hardware to the latest version or raising the bitrate settings of the video encoding presets in your transcoder template often resolves the problem. If that doesn't work, you can use the following workaround to reduce the effect and improve the stream quality. ...

    Sometimes it's better to run multiple instances of Wowza Media Server™ on a single computer rather than running one large instance with multiple virtual hosts. For example:

    • Available resources are wasted because they can't be used by a single instance.

    • Your streaming workflow involves a custom design that won't work using a single instance.

    • You're testing a multiple-server deployment on a single computer.

    This article describes how to run multiple instances of Wowza Media Server on one computer. All Wowza Media Server instances must be properly licensed. ...
