add(filter, args=None, **kwargs)
add_abuffer(template=None, sample_rate=None, format=None, layout=None, channels=None, name=None, time_base=None)

Convenience method for adding abuffer.

add_buffer(template=None, width=None, height=None, format=None, name=None, time_base=None)
configure(bool auto_buffer: cython.bint = True, bool force: cython.bint = False)
configured

Links nodes together for simple filter graphs.

pull()
push(frame, int at: cython.int = -1)

Push a frame into the graph’s buffer source(s).

Parameters:
  • frame – An AudioFrame or VideoFrame to push into the matching buffer sources, or None to signal end of stream to every buffer source.

  • at (int) – Index of a single buffer source to push to, for graphs with multiple inputs (e.g. overlay). The default of -1 pushes to every buffer source matching the frame’s type.

set_audio_frame_size(frame_size)

Set the audio frame size for the graphs abuffersink. See av_buffersink_set_frame_size.

threads

Maximum number of threads used by filters in this graph.

Set to 0 for automatic thread count. Must be set before adding any filters to the graph.

Wraps AVFilterGraph.nb_threads.

vpull()

Like pull, but only for VideoFrames.

vpush(VideoFrame frame: VideoFrame | None, int at: cython.int = -1)

Like push(), but only for VideoFrame.
