Expand description
Required methods
See add_asset_full()
, which also gives an error.
asset
The asset to extract the new clip from
start
The property::TimelineElement::start
value to set on the new clip
If start ==
GST_CLOCK_TIME_NONE``, it will be added to the end
of self
, i.e. it will be set to self
’s duration
inpoint
The property::TimelineElement::in-point
value to set on the new
clip
duration
The property::TimelineElement::duration
value to set on the new
clip
track_types
The property::Clip::supported-formats
to set on the the new
clip, or TrackType::UNKNOWN
to use the default
Returns
The newly created clip.
