arm64 support: Docker Images

[nervous-inhuman]

Hi,

I'm migrating my setup away from x86_64 into a arm64 machine, and I've noticed that media-repo images don't have an image for this architecture.

Would you consider whether adding build support for this architecture is feasible?

Thanks!

I found an issue with the gomodule github.com/jdeng/goheif/libde265 on aarch64:

# github.com/jdeng/goheif/libde265
g++: error: unrecognized command-line option ‘-msse4.1’

Related to this issue: https://github.com/jdeng/goheif/issues/18 and they mention a drop-in replacement gomodule: https://github.com/adrium/goheif

Patch to make media-repo work on aarch64:

FYI, with the latest release, this cropped up instead: Error relocating /usr/local/bin/media_repo: _ZSt28__throw_bad_array_new_lengthv: symbol not found

[turt2live]

In testing the build locally on an arm64 VM, this is working again. The next release won't have pre-built arm64 images, but folks should be able to build their own.
