FFmpegExporterClient

class FFmpegExporterClient implements Exporter

FFmpeg video exporter.

Most of the export logic is handled on the server. This class communicates with the FFmpegBridge through a WebSocket connection which lets it invoke methods on the FFmpegExporterServer class.

For example, calling the following method:

async this.invoke('process', 7);

Will invoke the process method on the FFmpegExporterServer class with 7 as the argument. The result of the method will be returned as a Promise.

Before any methods can be invoked, the FFmpegExporterServer class must be initialized by invoking start.
