Problem with video playback with copy codec

[aleksandrdobrynin]

Hey.

I add cameras with RTSP stream. I specify copy as the codec. Everything is great adding and showing video in Home app on phone. But when you start a broadcast on Apple TV, the broadcast doesn't start. Tell me what could be the problem?

Hello, I am 99% sure that problem is your configuration but don't worry. We will try to figure it out!

Let's follow these steps at first:

• stop node-red
• run node-red with debug DEBUG=NRCHKB* node-red
• configure Camera Control in Service Node in node-red and tick Debug in Camera section
• pair Camera Bridge in Home.app
• open stream for Camera in Home.app
• error will be printed in console (in place where you executed command to start node-red) but will also print ffmpeg command that was used to open stream
• run that command in terminal separately to get real problem

Also if you get any errors you can of course share them here.

This opens the picture as a snapshot, but the broadcast does not start.

@aleksandrdobrynin I feel like you cut something of the logs?
