I self-host MeTube, and have a shortcut set up for my share-screen. When I see a video I want downloaded, I hit the Share button, and press the custom script that sends the link to be downloaded onto my Emby server.

The fundamental problem is that there’s money to be made by consuming more and more “sustainable” resources. The real solution is to reduce consumption on a global scale.

What do you mean by “I do not download and upload at the same time”?
