"Now Playing" video feed

[DJay-X]

First of all thanks for your great work and sharing. @SphtKr

I use homebridge-itunes with a second homebridge (1st and main is on a Raspi).
Everything works great. macOS 10.12.5 iTunes 12.6.1.25 with an Apple TV 4 to AirPlay to, a Speaker in the Bedroom and one in the Bathroom.
Now I was curious about the "Now Playing" video feed.
I installed the homebridge-camera-ffmpeg plugin, added the lines in the config.json and after a restart the "camera" in the Eve App.
Then I find a switch "Now Playing" in the App but can't figure out how it works?! There is no picture what I would expect. What am I doing wrong?

Do I have to change the line into something other and into what?
"source": "-re -loop 1 -framerate 1 -r 1 -i /tmp/homebridge-itunes-nowplaying.jpg",

And when I have fixes this thanks to your support, I was wondering if there would be any chance to see Artwork of a track or album playing as still image in the future?

Thanks in advance for your help and reply.

Add

"enable_now_playing": "true",

to the iTunes now playing platforms!

Example:

{
"platform": "Camera-ffmpeg",
"enable_now_playing": "true",
"cameras": [{
"name": "iTunes Now Playing",
"videoConfig": {
"source": "-re -loop 1 -framerate 1 -r 1 -i /tmp/homebridge-itunes-nowplaying.jpg",
"maxStreams": 2,
"maxWidth": 480,
"maxHeight": 480,
"maxFPS": 2
}
}

@martinorob Thanks a lot for your reply. With your help I was able to add a Camera "Now Playing" to my Home App. But unfortunately not showing anything.
I use this instance of Homebridge on my iMac only with homebridge-itunes and now homebridge-camera-ffmpeg. So my config.json on the Mac is sort of clearly arranged. :)
Could the "source" be the mistake? I'm completely unaware of where the .jpg is.
Thanks again.

Your configuration is broken.

                  }
                  ]
}

then simply create a fake jpg file with

touch /tmp/homebridge-itunes-nowplaying.jpg

then kill Homebridge and restart Homebridge.
open your Now Playing webcam from the Home app (to view it on fullscreen and also to refresh the image).

[DJay-X]

Thanks again. But unfortunately I'm not sure what I am doing wrong. 😕🤷🏼‍♂️
When I check Finder, in the directory /tmp/ there is the homebridge-itunes-nowplaying.jpg I created. But always just with the time I created it. So it's not updating. Also there is a new file homebridge-itunes-nowplaying.txt which is updating steady with the playing state, titele etc. while playing a song in iTunes. But in the Home app the Camera "Now Playing" always shows no response with the crossed out camera symbol. 🤔
Thank in advance for any further support.

Hmm.. what should I look for? Anything specific?

Can you stop homebridge
delete ~/.homebridge/accessories/cachedAccessories
delete the Now Playing webcam accessori from your home application
restart homebridge
re add Now Playing webcam to home application?

[DJay-X]

@martinorob I hope not to bother. After some time of homebridge abstinence, I unfortunately have to come back with the missing video feed issue. :(

I noticed when I start homebridge manually live video works Home App ans shows the Album Artwork etc. In the folder /tmp the file homebridge-itunes-nowplaying.jpg is updated frequent. Together with homebridge-itunes-artwork.jpg, homebridge-itunes-nowplaying.txt and homebridge-itunes-artwork.tmp

But when I start homebridge with launchctl load ~/Library/LaunchAgents/com.homebridge.server.plist the file homebridge-itunes-nowplaying.jpg is not updated anymore. The other three files are still updating. In Home App the camera is not giving response.

Thanks again for your help and the time you are investing.

[martinorob]

Try to put the full path for the jpg..

like "/Volumes/SSD750GB/tmp/homebridge-itunes-nowplaying.jpg"

[DJay-X]

Thanks. But that doesn't solve it.
As mentioned the three other files are updating what I can see in Finder.

Only the homebridge-itunes-nowplaying.jpg stays the same when homebridge runs as
launchctl load ~/Library/LaunchAgents/com.homebridge.server.plist

Changing the file in the config.json to homebridge-itunes-artwork.jpg helped neither.
Camera still not responding.
Ending homebridge with launchctl unload ~/Library/LaunchAgents/com.homebridge.server.plist and just start it again with homebridge and put back the path to /tmp/homebridge-itunes-nowplaying.jpg and everything works great ant the live view is switched on immediately.

So I assume it's more something how homebridge starts then just the path to a file in the config.json.
🤔🤷🏼‍♂️
