-/* In this interface, a `track' is a unit of recording or playback, pretty much
- * equivalent to what comes in or goes out through a GstPad. Each track can have
- * one or more `channels', which are logical parts of the track. A `stereo
- * track', then, would be one stream with two channels, while a `mono track'
- * would be a stream with a single channel. More complex examples are possible
- * as well ; for example, professional audio hardware might handle audio tracks
- * with 8 or 16 channels each.
- *
- * All these are audio terms. I don't know exactly what this would translate to
- * for video, but a track might be an entire video stream, and a channel might
- * be the information for one of the colors in the stream.
