[yoyomax80400]

NRCHKB Plugin Version

1.5.0

Node JS Version

18.16.0

NPM Version

9.6.6

Node-RED Version

3.0.2

Operating System

Home assistant ingress docker

What happened?

I setup a camera control with all basic information see below :

---

If i launch the stream in the home.app, the stream never showing up.
In debug mode i can see only one error :

2023-06-15T09:36:17.093Z CameraSource-Error ERROR: FFmpeg exited with code 1
2023-06-15T09:36:19.823Z CameraSource-Error ERROR: FFmpeg exited with code 1

I tried in terminal the FFPMEG command :

# docker exec -t $(docker ps -f name=a0d7b954_nodered -q) ffmpeg -re -rtsp_transport tcp -i rtsp://admin:XXXXX@192.168.1.76:8554/Streaming/Channels/101 -loglevel debug

This is the ouput :

How to reproduce?

1 - Create a camera control
2 - Fill the all the input box
3 - Pair the accesory or bridge
4 - Watch the log

Expected behavior:

No response

Additional comments?

@marcus-j-davies do you want to do an ffmpeg help?

[marcus-j-davies]

@yoyomax80400

Ignore the output error! Your not setting a save file - so that is expected, and is not related to seeing a stream in iOS.

But your config does need sorting.

Video Encoder : set to libx264 or h264_v4l2m2m - the built in one is not optimised, and performs poorly.

Audio Encoder : set to libfdk_aac

Max Bitrate : Set to 300

Image source : set same as source (or an image url if you know it)

[yoyomax80400]

@marcus-j-davies,
Thanks for reply, yes i know i didn't provide a file to save the stream, if i provide one, the stream working in terminal and the mp4 file contain the stream

I made the change you tell me, but still getting the issue ... in IOS the stream won't load and in the log i get :
2023-06-15T12:07:50.184Z CameraSource-Error ERROR: FFmpeg exited with code 1

Edit :
I try to put the stream in Image source bellow the error :
[Camera] Snapshot request handler provided empty image buffer!

[marcus-j-davies]

What codec is your camera pushing?

Remember to use the codecs I suggested in the config, if they are not, iOS will not work

[yoyomax80400]

The camera codec is set to H264

[marcus-j-davies]

Ok, just to clear up any confusion.

Codec on the node config must be one that I said (and Audio as well). And is your camera natively sending h264 frames?

The node config FPS, ideally should be lower than native fps on the cam?

Have you changed anything else on the config? Like additional args, filter?

It's FFMPEG that's not happy with something.

[yoyomax80400]

From the camera:
Video codec : H264
Fps : 25
Resolution : 1920*1080

I didn't change anything else from the config ... i don't understand why i got a FFMPEG exit code, instead i try "Scryben" docker image, set to ffmpeg and it's work too, i try on home assistant and working too :(
But unfortaly, i would like this in node-red

@Shaquu @crxporter

Is there a debug flag or some kind one can add, to see the stderr of the ffmpeg process in NRCHKB?

[yoyomax80400]

I have no idea ..

i already add DEBUG=NRCHKB*,CameraSource* from init_command no change ..

let me ask on the dev github of the ingress add-on

[yoyomax80400]

https://nrchkb.github.io/wiki/service/camera-control/#how-to-debug-issues

Yes i already read the doc about how to debug ... but i think there are something to do with node-red as add-on in home assistant for see the debug
I opened a issue on the add-on github, i'm waiting for a answer

[yoyomax80400]

I'm no able to control the docker from home assistant OS.

Can anyone help me to start nodered container with param ?
I cannot use 'docker run' cause it will create a new container and could not be instantiated in home assistant OS

[Shaquu]

I am not using the home assistant. Can you ask on their channels?

[yoyomax80400]

Already did but no anwser from them ... still waiting to fix the trouble

[yoyomax80400]

Since nobody answer on the issue, may be i can give further information about FFMPEG.
See below the log when i start node-red :

Do you think FFMPEG is not the correct one ? or a library is missing ?

Any update?
