![]() Here’s the file, with both video and audio. Note that the file is H.264-encoded video and AAC-encoded audio. The program downloads Jan Ozer – MPEG-DASH explained and HTML5 Video-hWbCSAcNOCU.mp4 with the file details shown in Figure 2, most notably that the program downloads both video and audio and muxes it into a file that’s ready for viewing. Here’s what things look like during operation. Here’s what it looks like in the Command window. Here, you’re calling the command and listing the URL of the YouTube video to download. ![]() To download the highest quality video iteration, use this string: Navigate to the YouTube video that you want to download. I’m just going to cover a very basic feature set that I found very useful in my research. There’s an extensive and useful discussion here on what comprises a youtube-dl command string and the program’s core functions. If you’ll be experimenting with multiple functions you’ll want to print this out. Here’s the program documentation which is very well organized and specific. So, I’m not sure if you need FFmpeg installed or not. ![]() However, when I changed the folder to ffmpegx and didn’t update the path youtube-dl worked as normal. I have FFmpeg installed at c:\ffmpeg\bin on my test computer and it’s in the file path, so presumably, youtube-dl could easily find it. Note that some articles on youtube-dl indicate that FFmpeg is needed, which makes sense during the file consolidation phase. If you need more detailed help on getting the program installed, check here. Installation for other platforms is covered on the linked page. I downloaded the Windows version mentioned so I didn’t need Python installed (though it was). You can download the specific file that you want to download so, if you want the 1080p AV1 version, you can.You can generate a file list of all encodes performed by YouTube for a particular file, which I find useful for research (see here).There are many tools that let you download videos from YouTube. Again, I tested only on YouTube and didn’t encounter any encrypted files. Note that youtube-dl does not “crack” files encrypted with PlayReady, Widevine, or presumably FairPlay, so if the video files are encrypted with these technologies, you may be able to download them but the result won’t be playable. Here’s a list of over 700 sites that youtube-dl supports, which includes Vimeo and Udemy, though I only tested on YouTube. More specifically, youtube-dl downloads the individual fragments that make up the audio and video and then consolidates them into a single file. It is released to the public domain, which means you can modify it, redistribute it or use it however you like. youtube-dl should work in your Unix box, in Windows, or in Mac OS X. We also provide a Windows executable that includes Python. It requires the Python interpreter (2.6, 2.7, or 3.2+), and it is not platform-specific. Youtube-dl is a command-line program to download videos from and a few more sites.
