# 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](https://www.ffmpeg.org/download.html#build-windows).
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()
```
