Code before:

            status = traverse_obj(video_js_data, ('LiveRoomInfo', 'status'), expected_type=int) or 4
            is_live = status == 2  # Not currently live is 4, other numbers have not been encountered for the time being

            base_dict = {

            if is_live:

                if self.suitable(liveUrl):  # Prevent infinite loop in case redirect fails

Review comment (suggestion):
move all those info_dict values into return
```suggestion
                return {
                    'id': room_id,
                    'title': title,
                    'uploader': uploader,
                    'formats': formats,
                    'is_live': is_live,
                }
```
