Not sure I follow. The snap can contain whatever you want, binaries,
libraries etc. At build time you can specify 'build-packages' required
by the compilation, and 'stage-packages' required to be inside the
snap at runtime. Here's [0] an example yaml (for ffmpeg) which might
illustrate this. I knocked this together via a bit of trial and error,
so it's not necessarily confirming to your build standards or
recommended enabled options, but it should give you an idea.

Snaps have a couple of interesting concepts. The snap itself is a
squashfs file so is compressed and read-only on-disk. So in some
circumstances ends up being a smaller on-disk footprint than a
traditional install of ffmpeg via a typical package manager. We also
support delta updates to minimise download (and upload) bandwidth. Our
build service (backed by launchpad) can do the builds for you too, if
needed.

That would be awesome. Thanks.

We have a forum [1] where the snapd and snapcraft developers hang out.
If you get stuck in terms of documentation or bugs, feel free to post
there or ping me personally.

Now, you have been heard :)

I'd never heard of Linuxbrew! Thanks.

Would this only grant access to the binaries, or also the
libraries/development files?

It'd be debatable which dependencies the built ffmpeg includes. A
minimal ffmpeg without most/any dependencies is already big enough, but
when bundling all external dependencies, it would result in a quite huge
download.

I'll have a look at this if nobody else is super eager to jump at it.

On number of Linux distributions you can use Linuxbrew:

  brew install ffmpeg --with-the-parameters-you-wish

It works pretty well! We use it on Ubuntu and on Slackware.
Most of the Homebrew packages are available also on Linuxbrew.

Best regards, Reto
