Trait containing all UriClipAsset methods.

Implementors

UriClipAsset

Required methods

fn duration(&self) -> Option<ClockTime>

Gets duration of the file represented by self

Returns

The duration of self

fn info(&self) -> Option<DiscovererInfo>

Gets gst_pbutils::DiscovererInfo about the file

Returns

gst_pbutils::DiscovererInfo of specified asset

fn max_duration(&self) -> Option<ClockTime>

This is supported on crate feature v1_18 only.

Gets maximum duration of the file represented by self, it is usually the same as GESUriClipAsset::duration, but in the case of nested timelines, for example, they are different as those can be extended ‘infinitely’.

Returns

The maximum duration of self

fn stream_assets(&self) -> Vec<UriSourceAsset>

Get the GESUriSourceAsset self containes

Returns

a GList of UriSourceAsset

fn is_image(&self) -> bool

This is supported on crate feature v1_18 only.

Gets Whether the file represented by self is an image or not

Returns

Whether the file represented by self is an image or not

fn set_duration(&self, duration: u64)

The duration (in nanoseconds) of the media file

fn is_nested_timeline(&self) -> bool

This is supported on crate feature v1_18 only.

The duration (in nanoseconds) of the media file

fn connect_duration_notify<F: Fn(&Self) + 'static>(
    &self,
    f: F
) -> SignalHandlerId

fn connect_is_nested_timeline_notify<F: Fn(&Self) + 'static>(
    &self,
    f: F
) -> SignalHandlerId

This is supported on crate feature v1_18 only.
