ntt.videos.display.display_video(video)#

ntt.videos.duration module#

ntt.videos.exif module#

Technical metadata extraction for videos.

Two backends with the same interface so they can be used interchangeably:

extract_metadata_opencv – uses cv2.VideoCapture (no subprocess).
extract_metadata_ffprobe – uses ffmpeg-python (already a project dependency).

Both functions: - Accept a video file path. - Return a dict with consistent keys:

width, height, fps, frame_count, duration_s, codec.

Raise FileNotFoundError if the file does not exist.

ntt.videos.exif.extract_metadata_ffprobe(video_path: str) → dict#

Extract technical metadata from a video using ffprobe (via ffmpeg-python).

Parameters:

video_path (str) – Path to the video file.

Returns:

Keys: width, height, fps, frame_count,: duration_s, codec.

Return type:

dict

Raises:

FileNotFoundError – If the file does not exist.

ntt.videos.exif.extract_metadata_opencv(video_path: str) → dict#

Extract technical metadata from a video using OpenCV.

Parameters:

video_path (str) – Path to the video file.

Returns:

Keys: width, height, fps, frame_count,: duration_s, codec.

Return type:

dict

Raises:

FileNotFoundError – If the file does not exist.
