Class Details

class GES.TestClip(**kwargs)

Bases:

GES.SourceClip

Abstract:

No

Structure:

GES.TestClipClass

Useful for testing purposes.

Asset

The default asset ID is GES.TestClip, but the framerate and video size can be overridden using an ID of the form:

`` framerate=60/1, width=1920, height=1080, max-duration=5.0 `` Note: max-duration can be provided in seconds as float, or as GstClockTime as guint64 or int.

classmethod new()

Returns:

The newly created GES.TestClip, or None if there was an error.

Return type:

GES.TestClip or None

Creates a new GES.TestClip.

classmethod new_for_nick(nick)

Parameters:

nick (str) – the nickname for which to create the GES.TestClip

Returns:

The newly created GES.TestClip, or None if there was an error.

Return type:

GES.TestClip or None

Creates a new GES.TestClip for the provided nick.

get_frequency()

Returns:

The frequency self generates. See audiotestsrc element.

Return type:

float

Get the frequency self generates.

get_volume()

Returns:

The volume of the test audio signal applied on self.

Return type:

float

Get the volume of the test audio signal applied on self.

get_vpattern()

Returns:

The GES.VideoTestPattern which is applied on self.

Return type:

GES.VideoTestPattern

Get the GES.VideoTestPattern which is applied on self.

is_muted()

Returns:

Whether the audio track of self is muted or not.

Return type:

bool

Let you know if the audio track of self is muted or not.

set_frequency(freq)

Parameters:

freq (float) – the frequency you want to use on self

Sets the frequency to generate. See audiotestsrc element.

set_mute(mute)

Parameters:

mute (bool) – True to mute the audio track, False to unmute it

Sets whether the audio track of this clip is muted or not.

set_volume(volume)

Parameters:

volume (float) – the volume of the audio signal you want to use on self
