FfmpegStream class
A single video/audio stream pair within an FFMPEG filter graph.
A stream might include a video ID, or an audio ID, or both.
Every filter chain in an FFMPEG filter graph requires one or more input streams, and produces one or more output streams. From a CLI perspective, these streams are just string names within the filter graph configuration. However, these string names need to match, as outputs from one filter chain are used as inputs in another filter chain. To that end, these streams are represented by this class.
