After that the Apple TV does not appear in HomeKit. Please help. Thank you!

I changed the config features from both true to both false:
"features": {
"no-volume-controls": false,
"input-controls": false
}
and now I get the error:

Yep, +1 on this, haven't figured out a way around it as of yet.

Same here

hello, I have that issue me too.
I run homebridge in a docker on my nas synology

[darsenval]

Hello, me too.
Also run in a Docker on Synology.
All the installation was clear.
Updating DacpConnection.js with "Remote/1021" did not help.

[CubGeek]

Seeing this error in the log files as well. However, I do _not_have an AppleTV. The Homebridge system is on an old netbook I have and is connecting to my desktop computer's iTunes installation (Windows 7).

Ubuntu 18.04 LTS
node v11.7.0
homebridge v0.4.45
homebridge-dacp v0.9.2

same here, controlling iTunes on mac from homebridge on RPi ZeroW

[machineglow]

found out about this plugin recently and tried to set it up and ran into this issue.

Is there a way to get the plugin working? Sounds like there's a bunch of new properties in the DACP protocol that isn't supported...

Are other people still able to control itunes with these errors?

[machineglow]

after finding the PR with the changes that fix the bytelength error, I implemented the changes (with an additional change to line 929). I can now control itunes play/pause using the alternate-playpause-switch. Not sure if there's a way to control skipping in itunes.

oh well, better than nothing =)
