ffmpeg not found

[timwis]

Hi team 👋🏻 I've been setting up the devcontainer on an existing rails project, and noticed that ffmpeg was not available on the command line within the devcontainer. I just setup a fresh rails app to see if I could reproduce and isolate the issue (using rails _7.2.0.beta3_ new devcontainer_test --devcontainer), and it's not available in that devcontainer either.

The reason I believe it's not been installed is because I've tried the following commands:

$ ffmpeg
bash: ffmpeg: command not found

$ apt list --installed | grep ffmpeg

$ dpkg --get-selections | grep ffmpeg

grepping for vips or pop (the other two packages installed by activestorage/install.sh) does find a match; it's just ffmpeg that seems to be missing.

When I run sudo apt-get update && sudo apt-get install ffmpeg after the devcontainer is running, it installs fine.

I'm not familiar enough with devcontainers to know how to diagnose the issue properly, but I've looked through the "Show All Logs..." results in vscode and found this clue in one build:

I tried copying the activestorage feature to a local directory, and using that in my devcontainer.json, then modifying install.sh to add apt-cache policy ffmpeg after apt-get update, and it does look like it's available 🤔

Any suggestions on how to further diagnose?

Oh my goodness - it was the comments?! haha I don't think I'd have thought to try that! Thanks @andrewn617, I appreciate the fix.
