What happened ?

The video isn't support, as it seems. I don't have the time to look into this right now. But just for you to know: Please do not use 'sudo' for youtube-dl. In general, you should always use command line tools without sudo (full system privileges), if not explicitly required, as anything else makes you more vulnerable to security issues.

@kayb94 not safe getters: talk_info['nativeDownloads']
