Review comment (bug):
core code takes care of the default title. We can also partially inline this below. Also extended to properly parse the videojs object
```suggestion
        videojs_data = self._search_json(
            r'videojs\(["\'][^"\']+["\'],', player_config, 'videojs data',
            video_id, transform_source=js_to_json)
        formats = []
        subtitles = {}
        for src in traverse_obj(videojs_data, ('sources', lambda _, v: url_or_none(v['src']))):
            src_type = src.get('type')
            if src_type == 'application/x-mpegURL':
                fmts, subs = self._extract_m3u8_formats_and_subtitles(
                    src['src'], video_id, 'mp4', m3u8_id='hls', fatal=False)
                formats.extend(fmts)
                self._merge_subtitles(subs, target=subtitles)
            else:
                self.report_warning(
                    f'Unknown format type {src_type}{bug_reports_message()}')
```
