I have wondered why Real Player never seemed, over a period of years (some years ago, at least), to need updates to cope with downloading from YouTube, and yet youtube-dl seemed to need regular updates every few months. * https://www.real.com/uk/features https://www.real.com/uk/features ("download web videos from popular sites like YouTube and Vimeo") It's an architectural difference, but it is unclear what it is. It cannot be because RealPlayer Downloader is a browser extension that provides a "download" button within the WWW page itself and youtube-dl works from URLs given on a command line, because other YouTube downloaders like iTube are also able to download a video given only a YouTube page URL. * https://itube.aimersoft.com/free-mac-youtube-downloader.html https://itube.aimersoft.com/free-mac-youtube-downloader.html ("free download YouTube videos to Mac in a Click.") Or maybe it isn't a difference nowadays. This was some years ago. But there does not seem to be much talk about having to update these downloaders frequently like youtube-dl.
