>If the youtube parts of youtube-dl are non-free, wouldn"t that make this part of VLC non-free?

Portions of VLC are indeed non-free: looks like almost a mirror image of youtube-dl's parse_sig_js() function.

Also, it's worth noting that not all YouTube videos require JS to be executed. I've written about it before at I should have transferred the information here earlier, and am extremely sorry for not having done so- but basically, the requirement to use JS is a form of DRM on some videos. Many videos on the site can still be obtained without running the code at all. Indeed, a number of downloaders (the Unplug browser extension comes to mind, as well as JadedCtrl's ShellTube) don't, instead throwing an error/crashing/doing nothing when asked to source a 'DRMed' video.

By the way, if anybody's interested, I'm working on a no-JS/SWF/SDK version of YouTube-DL ( It's not perfect, but it removes close to a bear minimum of functionality.
