Without a docstring, it's difficult to see the point of this method since it just calls another method right away, making it kinda useless. Is the idea to have different ways of getting the metadata? E.g.

```python
def get_metadata(video_filepath):
    if filetype is ogg
        return get_metadata_from_mutagen(video_filepath)
    if filetype is ...
        return get_metadata_from_foo(video_filepath)
```
