Virtual Methods

create_source 

GstElement *
create_source (GESSource * source)

Creates the GstElement to put in the source topbin. Other elements will be queued, like a volume. In the case of a AudioUriSource, for example, the subclass will return a decodebin, and we will append a volume.

Parameters:

source –

The GESAudioSource

Returns ( [transfer: floating]) –

The source element to use.

Since : 1.20

vfunc_create_source 

function vfunc_create_source(source: GES.Source): {
    // javascript implementation of the 'create_source' virtual method
}

Creates the GstElement to put in the source topbin. Other elements will be queued, like a volume. In the case of a AudioUriSource, for example, the subclass will return a decodebin, and we will append a volume.

Parameters:

source (GES.Source) –

The GES.AudioSource

Returns (Gst.Element) –

The source element to use.

Since : 1.20

do_create_source 

def do_create_source (source):
    #python implementation of the 'create_source' virtual method

Creates the GstElement to put in the source topbin. Other elements will be queued, like a volume. In the case of a AudioUriSource, for example, the subclass will return a decodebin, and we will append a volume.

Parameters:

source (GES.Source) –

The GES.AudioSource

Returns (Gst.Element) –

The source element to use.

Since : 1.20

select_pad 

gboolean
select_pad (GESSource * source,
            GstPad * pad)

Check whether pad should be exposed/used.

Parameters:

source –

The source for which to check if pad should be used or not

pad –

The pad to check

Returns –

TRUE if pad should be used FALSE otherwise.

Since : 1.20

vfunc_select_pad 

function vfunc_select_pad(source: GES.Source, pad: Gst.Pad): {
    // javascript implementation of the 'select_pad' virtual method
}

Check whether pad should be exposed/used.

Parameters:

source (GES.Source) –

The source for which to check if pad should be used or not

pad (Gst.Pad) –

The pad to check

Returns (Number) –

true if pad should be used false otherwise.

Since : 1.20

do_select_pad 

def do_select_pad (source, pad):
    #python implementation of the 'select_pad' virtual method

Check whether pad should be exposed/used.

Parameters:

source (GES.Source) –

The source for which to check if pad should be used or not

pad (Gst.Pad) –

The pad to check

Returns (bool) –

True if pad should be used False otherwise.

Since : 1.20
