Goals: Add links that are reasonable and good explanations of how stuff works. No hype and no vendor content if possible. Practical first-hand accounts of models in prod eagerly sought.

Create a YouTube Art Track using HTML, CSS and ffmpeg

This may be more of a recipe than a tutorial, but let me just share the steps I followed to generate YouTube Art Track for my band, using intermediate computer skills.

Motivation

As a musician, sharing your music on YouTube is a must. But YouTube is a video platform, and making a music video to go with a song can be costly and time consuming. Several web services propose to generate a nice looking video out of your MP3 file, and to upload the result directly to your YouTube account, but this would cost you $30 per song in HD quality.

Expected output

How to recover your SwayWM socket in an SSH session.

I've run into a strange problem where sometimes, my monitors are forced to DPMS off and moving the cursor or pressing keys does not free it. I suspect this is a bug in my SwayWM configuration or a bug in Swaylock, but it resolves itself if I wait until the device again locks, which causes a second Swaylock instance to appear.

In any case, if you get yourself stuck and need to recover, you might want to be able to run swaymsg remotely. If you do, you might run into strange issues. swaymsg calls sway --get-socketpath to get the IPC socket, which... just returns the value of the SWAYSOCK environment variable. In my case, this also has the funny side-effect of starting a dbus session and SSH agent each time its invoked, because it is calling the NixOS-wrapped SwayWM binary. Probably should patch the NixOS version to explicitly call the unwrapped binary!

In order to recover the SWAYSOCK, one approach that should be relatively easy and does not requ
