/*
* Naming:
*
* A track is a single input/output stream (e.g. line-in,
* microphone, etc.). Channels are then single streams
* within a track. A mono stream has one channel, a stereo
* stream has two, etc.
*
* Input tracks can have 'recording' enabled, which means
* that any input will be hearable into the speakers that
* are attached to the output. Mute is obvious. A track
* flagged as master is the master volume track on this
* mixer, which means that setting this track will change
* the hearable volume on any output.
*/
/**
* GstMixerTrackFlags:
* @GST_MIXER_TRACK_INPUT: mixer track is for input
* @GST_MIXER_TRACK_OUTPUT: mixer track is for output
* @GST_MIXER_TRACK_MUTE: input or output is muted
* @GST_MIXER_TRACK_RECORD: input is audible in speakers attached to output
* (for #GST_MIXER_TRACK_INPUT mixer tracks only)
* @GST_MIXER_TRACK_MASTER: this mixer track is likely to be the master control
* @GST_MIXER_TRACK_SOFTWARE: mixer track's' volume control is implemented
* in software (as opposed to a hardware control)
* @GST_MIXER_TRACK_NO_RECORD: input track lacks support for recordable.
* Since: 0.10.23
* @GST_MIXER_TRACK_NO_MUTE: play track doesn't support mute. Since: 0.10.23
* @GST_MIXER_TRACK_WHITELIST: track should be displayed "by default" in apps.
* Since: 0.10.23
* @GST_MIXER_TRACK_READONLY: track is read-only. Since: 0.10.25
* @GST_MIXER_TRACK_WRITEONLY: track is write-only. Since: 0.10.25
