Signals

request-pad 

GstPad *
request_pad_callback (GstElement * encodebin,
                      GstCaps * caps,
                      gpointer udata)
def request_pad_callback (encodebin, caps, udata):
    #python callback for the 'request-pad' signal
function request_pad_callback(encodebin: GstElement * encodebin, caps: GstCaps * caps, udata: gpointer udata): {
    // javascript callback for the 'request-pad' signal
}

Use this method to request an unused sink request GstPad that can take the provided caps as input. You must release the pad with gst_element_release_request_pad when you are done with it.

Parameters:

encodebin –

a encodebin instance

caps –

a GstCaps

udata –
No description available
Returns ( GstPad * ) –

A compatible GstPad, or NULL if no compatible GstPad could be created or is available.

request-profile-pad 

GstPad *
request_profile_pad_callback (GstElement * encodebin,
                              gchararray profilename,
                              gpointer udata)
def request_profile_pad_callback (encodebin, profilename, udata):
    #python callback for the 'request-profile-pad' signal
function request_profile_pad_callback(encodebin: GstElement * encodebin, profilename: gchararray profilename, udata: gpointer udata): {
    // javascript callback for the 'request-profile-pad' signal
}

Use this method to request an unused sink request GstPad from the profile profilename. You must release the pad with gst_element_release_request_pad when you are done with it.

Parameters:

encodebin –

a encodebin instance

profilename –

the name of a GstEncodingProfile

udata –
No description available
Returns ( GstPad * ) –

A compatible GstPad, or NULL if no compatible GstPad could be created or is available.
