VideoTranscriptionSegmenter
The provided code defines a class `SegmentVideoAction` within nested modules `Sublayer` and `Actions`. This class is designed to process video transcription output by segmenting it based on timestamp information. The key functionalities and details of the code are outlined below:
1. **Initialization**: The `initialize` method takes a single argument `transcription_output`, which is expected to be a string containing transcription data of a video.
2. **Segmentation of Transcription**: The `call` method processes the `transcription_output`. It aims to create segments from the transcription based on timestamps. A regular expression `\[(\d{2}:\d{2}:\d{2})\]` is utilized to detect timestamps within the format `[hh:mm:ss]`.
- As it iterates through each line, if a timestamp is found, it marks the end of the current segment, appends it to the `segments` array, and starts a new segment.
- Text lines without timestamps are added to the current segment's text.
3. **Processing Segments**: The `process_segments` method is called with the array of segments. For each segment, it prints out the segment's start time, end time, and text. This demonstrates a basic operation that one might perform on such segments, though in a practical scenario, this could involve more complex processing or manipulation.
4. **Private Method**: The `process_segments` method is a private method, used internally by the class to handle post-segmentation logic.
Overall, the class is a template for segmenting transcript data to apply specific operations to each segment, useful in contexts where video content needs to be divided and analyzed by time-based sections.
