  • You can use the --download-sections parameter to specify a time range. --download-sections "*0-600" would download the first 600 seconds to the nearest keyframe. To make it exact, you would have to re-encode the video after downloading it.

    For making the thumbnail square, you will probably have to write a script to extract it, crop it, and re-insert it.













  • If the machine has 4GB of RAM, then MATE, XFCE, LXDE, and LXQT will work well. I’ve used all of them on older computers. The distro doesn’t really matter. If it has 8GB of RAM or more, it will run any DE you want to use.

    If the machine has less than 4GB of RAM and can’t be upgraded, it’s not going to be very useful. Sure, you can put a lightweight window manager on them, but they are not going to run a web browser well. They could still be used for teaching students how to install Linux though.


  • There are very lightweight media players available that will run on anything with enough CPU power to decode whatever codec you are playing. It’s modern web browsers that will be an issue with less than 4GB of RAM. There are lighter web browsers, but they usually don’t support javascript or have very limited support for it.
