This extension works together with i local installation of "ffmpeg" and "YouTube-DL" (from github).
My extension passes information to YouTube-DL, that does the actual download.
Here is a list of supported sites (from youtube-dl)
1: Install the Opera Extension
2: Install the "MS Visual C++ 2010 SP1 Redist (x86)" (Link will display in the Opera Extension)
3: Install the "YT-Download local installation" (Link will display in the Opera Extension)
