GI.GES.Objects.AudioTrack

A AudioTrack is a default audio Track, with a GES_TRACK_TYPE_AUDIO Track:trackType and "audio/x-raw(ANY)" Track:caps.

By default, an audio track will have its Track:restrictionCaps set to "audio/x-raw" with the following properties:

• format: "S32LE"
• channels: 2
• rate: 44100
• layout: "interleaved"

These fields are needed for negotiation purposes, but you can change their values if you wish. It is advised that you do so using trackUpdateRestrictionCaps with new values for the fields you wish to change, and any additional fields you may want to add. Unlike using trackSetRestrictionCaps, this will ensure that these default fields will at least have some value set.

class (GObject o, IsDescendantOf AudioTrack o) => IsAudioTrack o

Type class for types which can be safely cast to AudioTrack, for instance with toAudioTrack.

new

audioTrackNew

Arguments

:: (HasCallStack, MonadIO m)

=> m AudioTrack

Returns: The newly created audio track.

Creates a new audio track, with a GES_TRACK_TYPE_AUDIO Track:trackType, "audio/x-raw(ANY)" Track:caps, and "audio/x-raw" Track:restrictionCaps with the properties:

• format: "S32LE"
• channels: 2
• rate: 44100
• layout: "interleaved"

You should use trackUpdateRestrictionCaps if you wish to modify these fields, or add additional ones.
