Download Youtube Videos
目前為
A simple userscript for downloading Youtube Videos.
This script doesn't require any external scripts or libraries, the code you see is the code you get, everything is done locally within your browser.
It's very lightweight and should have a minimal performance impact.
Simply install one of the following: greasemonkey, tampermonkey, violentmonkey.
Click this link: ytDownloader.user.js
Your chosen addon should then provide you with an install option, simply follow the instructions.
Once installed, head over to Youtube and you'll find a "Download Links" button underneath the video, click this and it will show you a list of all the video & audio files available to download.
Simply right-click on your desired file and click save-as.
Due to the nature of Youtube, many of the videos you watch with a quality of 480p or higher, will actually be a seperate Audio and Video file, so while this script will grant you the ability to download all of these seperately, it cannot merge them.
Video quality of 360p and lower are combined Audio and Video files as you would normally expect.
You may find downloads are incredibly slow, this is due to Youtube streaming the video files to you as if you where watching them, so Youtube will only provide just enough information required to stream the video file in realtime, as a result download speeds can suffer greatly and it can simply be a matter for making a cup of tea and waiting around.
I may look into trying to download "sections" of video to download files quicker, however this is complicated and can require a lot more processing power than simply watching a video, so please don't get your hopes up for this feature anytime soon...
