cutcutcodec.core.filter.video.delay.FilterVideoDelay¶

class cutcutcodec.core.filter.video.delay.FilterVideoDelay(in_streams: Iterable[Stream], delay: Real)[source]¶

Change the beginning time of a stream.

Attributes¶

delayFraction: The delay append to the original beginning time of the stream (readonly). a positive value indicates that the output flow is later than the input flow.

Examples¶

>>> from cutcutcodec.core.filter.video.delay import FilterVideoDelay
>>> from cutcutcodec.core.generation.video.noise import GeneratorVideoNoise
>>>
>>> (s_base_video,) = GeneratorVideoNoise(0).out_streams
>>> (s_trans_video,) = FilterVideoDelay([s_base_video], 10).out_streams
>>>
>>> (s_base_video.snapshot(0, (1, 1)) == s_trans_video.snapshot(10, (1, 1))).all()
tensor(True)
>>> (s_base_video.snapshot(10, (1, 1)) == s_trans_video.snapshot(10, (1, 1))).all()
tensor(False)
>>>

Initialise and create the class.

Parameters¶

in_streamstyping.Iterable[Stream]: Transmitted to cutcutcodec.core.classes.filter.Filter.
delaynumbers.Real: The temporal translation value to apply at the output video stream.

property delay: Fraction¶: Return the delay append to the original beginning time of the stream.
