+_This contains everything with deciphered formats along with `video_details`. It uses data returned by [`video_basic_info`](https://github.com/play-dl/play-dl/tree/main/docs/YouTube#video_basic_infourl--string-options--infooptions). This function is useful if you use [`video_basic_info`](https://github.com/play-dl/play-dl/tree/main/docs/YouTube#video_basic_infourl--string-options--infooptions) earlier in your code and want to convert the output for use with [`stream_from_info`](https://github.com/play-dl/play-dl/tree/main/docs#stream_from_infoinfo--infodata-options--streamoptions)_
