Snapshot works, Stream does not → please help

[IT-Lueg]

Hello, can somebody please help me. I've been trying to create the stream correctly for days now.

The snapshot is taken and displayed in the app. But as soon as I click on the stream it just loads. And after a while I get the message "no Answer".

What am I doing wrong?

Config

        {
            "platform": "Video-doorbell",
            "cameras": [
                {
                    "name": "Haupteingang",
                    "port": 5005,
                    "button": true,
                    "videoConfig": {
                        "stillImageSource": "-i http://192.168.1.25/snap.jpeg",
                        "source": "-re -i rtsp://192.168.1.2:7447/5b8391c417cb480790fdda8b_0",
                        "maxWidth": 1280,
                        "maxHeight": 720,
                        "maxFPS": 15,
                        "debug": true
                    }
                }
            ]
        },

Output

FFMPEG works correctly. I know that because I use another plugin (homebridge-camera-ffmpeg-ufv) which also uses FFMPEG.

I looked a little further and after a long time I came across the following page. . . https://www.bountysource.com/issues/56801125-video-won-t-start-to-stream

After reading the comment of "johan-de-jong", I have edited my "ffmpeg. js" file and now it works

I am working with Ubiquiti Unifi Video Cameras so i changed my config from:

old Config

    let ffmpegCommand = this.ffmpegSource + ' -map 0:0' +
      ' -vcodec ' + vcodec +
      ' -pix_fmt yuv420p' +

new Config

        let ffmpegCommand = this.ffmpegSource + ' -threads 0' +
          ' -vcodec ' + vcodec + ' -an' +
          ' -pix_fmt yuv420p' +

Great that it is working now for your setup. Those parameters are often camera specific so it is a bit tricky to implement them in a general approach.

[Partizan7676]

Any suggestion - which camera has two way audio? I check two models from Hikvision - both not work. So does somebody get sound with ffmpeg camera plugin?

[Samfox2]

At this time there is no 2-way audio support with ffmpeg possible as ffmpeg cannot provide compatible stream.

@Partizan7676

yes I have

My current doorbell is made out of a cheap analog video doorbell and raspi, two-way audio!
