docker: Add VAAPI to arm64

[stgraber]

This adds the needed bits for VAAPI to be available on arm64.

Worth noting that the current jellyfin build does not include vaapi support, so I'm currently running with an alternate build of it which is then mapped directly to /usr/lib/jellyfin-ffmpeg. This works fine for now until I can convince the jellyfin folks to build with --enable-vaapi too :)

This being just for arm64 arch right? vaapi works fine in amd64 arch with jellyfin

[stgraber]

That's right. They build ffmpeg with vaapi on amd64 but not on the other architectures.

I ended up rebuilding their package with it enabled and then side loading that into my Frigate container, worked fine. So this suggests there's no particular reason not to build ffmpeg with it enabled.

Can you describe the process you used to "side load" a different ffmpeg version?

Sounds like a simple volume mount, something like:

-v /home/stgraber/ffmpeg-build/bin/ffmpeg:/usr/lib/jellyfin-ffmpeg

[stgraber]

Yep, that's exactly what I'm doing :)

  -v /data/frigate/ffmpeg:/usr/lib/jellyfin-ffmpeg

[stgraber]

The switch to jellyfin-ffmpeg actually made this much easier as it's all nicely self-contained in one directory rather than spread across the filesystem :)

@stgraber This happens to affect me too. Would you be willing to share your process for building the custom jellyfin-ffmpeg in the meantime, possibly for inclusion into the docs?

[stgraber]

@zeroping I cloned https://github.com/jellyfin/jellyfin-ffmpeg, then altered debian/rules and debian/control to add a basic dependency on vaapi:

And then built the whole thing by running ./build bullseye arm64

You'll end up with a bin/jellyfin-ffmpeg5_5.0.1-8-bullseye_arm64.deb or similar file in the parent directory. Unpack this with dpkg and you'll get the directory you need to replace.
