Use "mpp" from apt instead of building from source

Hmm, apparently this only works on Radxa images. Or maybe they have a separate repo, let me check

[seriyps]

turned out to be more difficult than I expected. Will make another attempt later

Does the Radxa repo include gst plugins for mppvideodec ?

You can see what is in their repo here https://radxa-repo.github.io/bullseye/files.list

But the problem with this PR is that Radxa repo is obviusly not included in standard Debian image and for some reason my attempts to add it fail.

Peeking into here https://radxa-repo.github.io/bullseye/pkgs.json I don't see librockchip-mpp-dev at all.

It's present and available in rsdk builds.

Finally success. The trick was to add 2 repositories, not one:

deb [signed-by=/usr/share/keyrings/radxa-archive-keyring.gpg] https://radxa-repo.github.io/bullseye/ bullseye main
deb [signed-by=/usr/share/keyrings/radxa-archive-keyring.gpg] https://radxa-repo.github.io/bullseye rockchip-bullseye main

Now build takes ~4 minutes instead of ~8!

This is for Radxa only, for the orange pi series one must add a separate repo. I've been using this:

@JohnDGodwin A-ha.. interesting. Well, we are using this library here just to test that pixelpilot can be successfully compiled on Debian Bullseye arm64 in GitHub CI. We can't run pixelpilot for real in CI because we don't have actual rockchip available in CI.

Do you think building pixelpilot with Raspberry version of the library will make any difference?

Or you saying we need to mention this PPA in the README?
