- `realtime` (default: `false`): Prioritize encoding speed over compression ratio and quality. With realtime mode turned off the worker will send a single `ArrayBuffer` containing the entire webm video file once input stream has ended. With realtime mode turned on the worker will send an `ArrayBuffer` in regular intervals.
- `kLive` (default: `true`): Set the webm writer to `kLive` mode when true, or to `kFile` mode when false. I am still not sure what the difference is except that `kLive` files are slightly smaller and work with MSE 🤷‍♂️
