VideoStreamPlayback #
is_refcounted, is_instantiable, resource, core, not_builtin_classes
Internal class used by VideoStream to manage playback state when played from a VideoStreamPlayer.
This class is intended to be overridden by video decoder extensions with custom implementations of VideoStream.
Members #
Methods #
virtual const func _get_channels() -> int#
Returns the number of audio channels.
virtual const func _get_length() -> float#
Returns the video duration in seconds, if known, or 0 if unknown.
virtual const func _get_mix_rate() -> int#
Returns the audio sample rate used for mixing.
virtual const func _get_playback_position() -> float#
Return the current playback timestamp. Called in response to the VideoStreamPlayer.stream_position getter.
virtual const func _get_texture() -> Texture2D#
Allocates a Texture2D in which decoded video frames will be drawn.
virtual const func _is_paused() -> bool#
Returns the paused status, as set by _set_paused.
virtual const func _is_playing() -> bool#
Returns the playback state, as determined by calls to _play and _stop.
virtual func _play() -> void#
Called in response to VideoStreamPlayer.autoplay or VideoStreamPlayer.play. Note that manual playback may also invoke _stop multiple times before this method is called. _is_playing should return true once playing.
virtual func _seek(time: float) -> void#
Seeks to time seconds. Called in response to the VideoStreamPlayer.stream_position setter.
virtual func _set_audio_track(idx: int) -> void#
Select the audio track idx. Called when playback starts, and in response to the VideoStreamPlayer.audio_track setter.
virtual func _set_paused(paused: bool) -> void#
Set the paused status of video playback. _is_paused must return paused. Called in response to the VideoStreamPlayer.paused setter.
virtual func _stop() -> void#
Stops playback. May be called multiple times before _play, or in response to VideoStreamPlayer.stop. _is_playing should return false once stopped.
virtual func _update(delta: float) -> void#
Ticks video playback for delta seconds. Called every frame as long as both _is_paused and _is_playing return true.
func mix_audio(offset: int = 0) -> int#
Render num_frames audio frames (of _get_channels floats each) from buffer, starting from index offset in the array. Returns the number of audio frames rendered, or -1 on error.
