Review comment (suggestion):
```suggestion
        formats = [{'url': url} for url in traverse_obj(json_data, ('mp4', ..., 'url')) or []]
        subtitles = {}

        for url in traverse_obj(json_data, ('hls', ..., 'url')) or []:

The headers from the main infodict will be automatically used for each format
