Extract meta data from video file

Metadata is text inside the video file that references the video. The Meta information of a video shows that what is included in the video and what type of content is available in the video.

Before getting into extraction, first you need to install ffmpeg.

- Ubuntu

sudo apt-get install ffmpeg

- Windows

Download ffmpeg software from FFMPEG official website. Unzip the file and add the bin folder to environment path.

Using MediaInfo class

	media_obj = Mediainfo()
	or
	media_obj = Mediainfo(VIDEO_PATH) # VIDEO_PATH must be string

Set video path if not passed

	media_obj.video_path = 'video_path'

Get video path

	VIDEO_PATH = media_obj.video_path

Extract metadata

	metadata = media_obj.getVideoDetail()

	frame = Extractframes(VIDEO_PATH)
	frame.extract_frames() # frame_path='', index=0 as optional arguments.
