GI.GES.Objects.VideoTrack

A VideoTrack is a default video Track, with a GES_TRACK_TYPE_VIDEO Track:trackType and "video/x-raw(ANY)" Track:caps.

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

• width: 1280
• height: 720
• framerate: 30/1

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.

new

videoTrackNew

Arguments

:: (HasCallStack, MonadIO m)

=> m VideoTrack

Returns: The newly created video track.

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

• width: 1280
• height: 720
• framerate: 30/1

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