No Sound for Cameras on aarch64

[YPyltiai]

Bug Report

Describe the Bug

Sounds in camera/doorbell feed doesn't work with aarch64 Raspbian 11 (Debian 11 Bullseye), while Homebridge is installed in Docker. I looked at Dockerfile and it should be installing FFMPEG fine, so something else looks to be going wrong.

To Reproduce

• Installed latest Raspbian 11 (Debian 11 Bullseye) on RPi
• Homebridge runs in Docker using https://github.com/oznu/docker-homebridge
• When trying to view camera/doorbell, getting error [Ring] Streaming video only - ffmpeg was not found. See https://github.com/dgreif/ring/wiki/FFmpeg for details. Sound is not working, though the camera itself does. Guide on that link mentioned supporting aarch64 but it doesn't work.
• https://github.com/oznu/docker-homebridge/blob/master/Dockerfile#L12-L20 seems to be installing FFMPEG into the image and I confirmed that uname -m will return aarch64, so I should be getting an image with FFMPEG but sounds still doesn't work

Expected behavior

Camera feed and sound work as expected.

Screenshots/Logs

[Ring] Streaming video only - ffmpeg was not found. See https://github.com/dgreif/ring/wiki/FFmpeg for details. Nothing else in logs that is out of normal.

Also just confirmed that FFMPEG is indeed in the container:

You should be able to manually set the ffmpegPath in your config to point to the ffmpeg binary. which ffmpeg should give you the path

@dgreif huge thanks - it worked. On the other note though - prior to Debian 11 64-bit it worked without requiring this config change. Not sure if the path changed but now you actually need to set it. I looked at recent image changes by @oznu , there are no changes around the way FFMPEG is pulled into the image, so not sure what caused this.

For reference - I had to add "ffmpegPath": "/usr/local/bin/ffmpeg" to fix the issue to homebridge-ring config. This also doesn't look to be available in UI, so has to be added to JSON directly.

@dgreif - got pinged on this so took a look to see what was going on.

It looks like there was a bug introduced in the ffmpeg-for-homebridge install script when the dependencies were updated a couple months ago that has meant ffmpeg is not getting downloaded.

If you bump the dependency to the latest version it should fix this issue.

Thanks @oznu! I've got the day off tomorrow so I'm hoping to get my beta branch into a releasable state, and will include that update in there.

@YPyltiai have you tried the latest version of the plugin (11+)?

[YPyltiai]

@dgreif I am on latest now but I haven’t changed the settings since last time since it didn’t hurt to just leave that variable there.
