Version: 1.62

Thumb Thumb

YouTube Links does two things. It tags every video link on a YouTube page so that they can be downloaded easily. On the watch page, it also shows all the available video formats at the top of the page.

The look-n-feel resembles YouTube HD Suite. I have been using it for a long time and like how it works. When it broke after YouTube changed its page format on 3rd August 2011, I decided to learn how it works and write my own from scratch.

Tested on Firefox 6.0 (with Greasemonkey), Chrome 13, Opera 11.50 and Safari 5.1.7 (with NinjaKit).

Not tested on IE. Won't work on IE 7.

Notable features

  • Shows the available file format, resolution (info from the page itself) and size
  • Scans the video links on the page in batches to avoid overloading the network
  • The video links have the correct filename, so they can be saved easily
  • Has an updater; checks for updates every 3 days
  • Uses localStorage instead of cookies

Limitations

  • There is currently no user options.
  • It does not auto-redirect to the highest/preferred video format.
  • Does not work on the mobile YouTube pages.
  • Most probably won't work on mobile browsers. Shows up on Tampermonkey (Android), but is unable to download the videos.
  • Obfuscated-sig videos do not work.

Adaptive Video Streaming

YouTube now uses adaptive video streaming for 480p and 1080p videos (Oct 2013). What this means is that the video and audio streams are now separate.

They are indicated as M4V and M4A. They have to be downloaded separately and mux'ed before playing. If using ffmpeg: ffmpeg -i vid.m4v -i vid.m4a -vcodec copy -acodec copy vid.mp4

The filename is always videoplayback. Before saving, select and copy the page title first. Then right-click on the video link, save-as and paste the title. Set the extension to either m4v or m4a to distinguish between video and audio.
