Python class

SampledVideo

SampledVideo

class max.pipelines.context.SampledVideo(frames, indices, info)

source

Bases: object

The frames kept from a video, and the source they came from.

Frames are held as uint8 (H, W, C) RGB arrays – the form PyAV produces – and converted on request. frame.to_ndarray("rgb24") is pixel-identical to frame.to_image().convert("RGB"), so callers that want images pay only for the wrapper, not a second conversion.

Parameters:

• frames (list[ndarray[tuple[Any, ...], dtype[uint8]]]) – The sampled frames, in indices order.
• indices (list[int]) – Source frame index of each entry in frames.
• info (VideoStreamInfo) – Stream metadata, with num_frames corrected to the count the decode actually produced.

array

source
