in case you have a wonky mic where the left channel sounds much louder than the right; here's an ffmpeg command to keep only the left channel in a video file, converting it from stereo to mono:

ffmpeg -i in.mp4 -af "pan=mono| c0=FL" -c:v copy out.mp4

alternatively, EasyEffects makes it simple to set up the stereo→mono mix once, then have it applied on every boot: https://github.com/wwmm/easyeffects (has nifty effects, too)

Examples of working Flake urls to private AzOps repos:

nix run 'git+https://pacifichealthdynamics.visualstudio.com/PHDSys/_git/PHDSys-net?ref=integration&rev=43fb2415eac77af745ef481de769327d95c69fe5#hippoApiRT'

nix run 'git+ssh://[email protected]/v3/pacifichealthdynamics/PHDSys/PHDSys-net?ref=integration&rev=43fb2415eac77af745ef481de769327d95c69fe5#hippoApiRT'

take a thread dump from a docker container running a mono process

...when the container has no shell, so docker exec -it won't work.

steps

identify the Container ID of the problematic container

$ docker stats

Should help with avoiding errors like:
