Problem with video playback with copy codec

aleksandrdobrynin commented 4 years ago

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?

I would recommend trying again with the latest images. If you are looking for omx support, and you are using raspbian please use -raspbian images.
