Everything requires you to be online nowadays, from time to time that can be pretty frustrating if you are traveling place where you know you won’t have internet. Youtube contains a lot of great content, but because they make money by showing advertisements (and a lot of them) the they have no builtin way that allows you to download the content for offline viewing.
Luckily there’s a nice community project, youtube-dl that allows you to download content from youtube, and a quite long list of other sources.
The tool is written in python and is a commandline too, the main problem is that it requires regular updating as youtube does many things to prevent people from downloading their videos. Personally I don’t do any python on my Windows machine, and it is quite rare that I need to download videos from youtube, but when I do I just need a quick and easy solution.
That is why it for me works perfectly to have the tool installed in a docker container. I found https://hub.docker.com/r/vimagick/youtube-dl/ this image receives regular updates and contains youtube-dl and ffmpeg (required to convert the videos).
To use the container all you have to do is run
docker run --rm -v c:/temp:/data vimagick/youtube-dl [Youtube-Video-Id]
The [Youtube-Video-Id] should be replaced with the video id of the video you want to download, they look like:
IC-bSbXZBcU note that they are case sensitive.
The video is downloaded to c:/temp which must have been shared with docker (if you use docker for windows, like me).
