基类：Mapper

Mapper to cut videos into scene clips.

Initialization method.

参数:

  • detector -- Algorithm from scenedetect.detectors. Should be one of ['ContentDetector', 'ThresholdDetector', 'AdaptiveDetector`].

  • threshold -- Threshold passed to the detector.

  • min_scene_len -- Minimum length of any scene.

  • show_progress -- Whether to show progress from scenedetect.

  • args -- extra args

  • kwargs -- extra args

process_single(sample, context=False)[源代码]#

For sample level, sample --> sample

参数:

sample -- sample to process

返回:

processed sample
