Mixer track flags.

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

Property Details

The "flags" property

  "flags"                    guint                 : Read

Flags indicating the type of mixer track.

Default value: 0

The "index" property

  "index"                    guint                 : Read / Write / Construct Only

Index of the mixer track, if available. Mixer track implementations must set this at construct time. This can be used to discern between multiple tracks with identical labels.

Default value: 0

Since 0.10.21

The "label" property

  "label"                    gchar*                : Read

The label assigned to the track (may be translated).

Default value: NULL

The "max-volume" property

  "max-volume"               gint                  : Read

The maximum possible volume level.

Default value: 0

The "min-volume" property

  "min-volume"               gint                  : Read

The minimum possible volume level.

Default value: 0

The "num-channels" property

  "num-channels"             gint                  : Read

The number of channels contained within the track.

Allowed values: >= 0

Default value: 0

The "untranslated-label" property

  "untranslated-label"       gchar*                : Read / Write / Construct Only

The untranslated label of the mixer track, if available. Mixer track implementations must set this at construct time. Applications may find this useful to determine icons for various kind of tracks. However, applications mustn't make any assumptions about the naming of tracks, the untranslated labels are purely informational and may change.

Default value: NULL

Since 0.10.13
