Add support for arm64

[sspans]

This introduces support for arm64, changes have been tested on the new arm64 Raspberry Pi OS.
Those images are generated by the pi-gen arm64 branch: https://github.com/RPi-Distro/pi-gen/tree/arm64.

For ffmpeg I've selected the 'debian' binary, which seems to work.

Thanks, I won't merge this just yet, as the actual building of the x64 image still needs to happen - I will be waiting until RaspbianOS 64bit is officialy released before looking into this (stablity is the most important thing for this image - I don't want to make users "beta" testers for RaspbianOS).

Hi,

Actually using the Homebridge Raspbian image 1.0.9 running on a Raspberry Pi 4 4G with a USB SSD without SD Card with no problem at all.
Would loves to update it to a 64 Bit version of Raspbian with the USB SSD providing better reliability compare to SD Card, but actually you need to clone an updated Raspbian (64 Bit or not) before to copy it to SSD.

but actually you need to clone an updated Raspbian (64 Bit or not) before to copy it to SSD.

The latest Homebridge Raspberry Pi images can be burnt directly to a USB, and so long as you have previously updated the firmware on the Raspberry Pi 4 to be from June 15th 2020 or later, it will boot without an SD card 😄

Didn't know !
Great will be more easy compare to current Raspbian OS...

Found a minor gotcha with the compression flags, but it should be good now.

[nscheffer]

Does it mean we could already build a 64 bit version to try ?

[sspans]

I'm running homebridge on 64bit raspberry pi os - and it works for me.
This PR fixes some minor issues with installing nodejs/ffmpeg/etc - while retaining support for 32bits.

Test versions should just work, but @oznu wants to wait until there's a final release of arm64 raspberry pi os.
Which makes sense imo.

[sspans]

@oznu any chance this could get merged now?

Hi,
I was thinking to switch to an arm64 image. I'm wondering if homebridge-raspbian-image could support arm64 and came to this thread.
I noticed that Raspberry Pi has been regularly updating their official 64-bit image with updates for more than a year now.

It will be great if we can merge this.

Hi, does the main branch support 64bit by now? - cheers

@mariosc The main branch is still using the 32 bit image of Raspbian. One concern with updating is support for older RPI's as RPI 2's or older are not 64 bit capable.
