I want to scrape information from a YouTube playlist/channel (including Upload Date, Title, URL, Duration, View Count) using `youtube-dl` without downloading the videos. 

There's a very useful example [here](https://archive.zhimingwang.org/blog/2014-11-05-list-youtube-playlist-with-youtube-dl.html) on how to use the `dump-json` switch together with `jq`, but it only output the URLs.

Basically, in the command line, how do I use the [keys](https://github.com/ytdl-org/youtube-dl/blob/master/README.md#output-template) with `dump-json`?
