11.1.4.1. Video Codec Options

Our application uses the GStreamer framework for video encoding, which supports hardware accelerators like Intel QuickSync and NVIDIA NVENC via dedicated plugins.

Each encoder plugin accepts its own set of parameters for tune.

You can specify these parameters in the "Video options" field using the key=value format.

Separate multiple parameters with a space.

Common parameters for popular encoders are listed below.

For a full list of available options, please refer to the official documentation links provided in each section.
