Review comment (bug):
as far i can see, we can set the `duration` and `description` from the `description` field in `json_data`. It looks like this:
```suggestion
        description_raw = self._html_search_meta(
            ['og:description', 'description', 'twitter:description'], webpage, 'description')
        duration, description = self._search_regex(
             r'(?P<duration>\d+)\s*-\s*(?P<description>[\w]+)', description_raw, 'description').group('duration', 'description')
```
However, i didn't test this. Please correct me if i'm wrong

Code after:
    strip_or_none,
    traverse_obj,
    try_call,
)
