Review comment (suggestion):
```suggestion
        base_media_url = (video['.transformUrl'].replace('/thumbnail?', '/videomanifest?')
                          + '&cTag={video[".ctag"]}&action=Access&part=index'))
```
Normally, I dislike +, but this is a good exception since below looks ugly
```py
        base_media_url = (f'{video[".transformUrl"].replace("/thumbnail?", "/videomanifest?")}'
                          f'&cTag={video[".ctag"]}&action=Access&part=index'))
```
