Black Record file

[lio00lio]

Hi all,

I just implemented Viseron on my system. I use casaOS for the hostOS (Debian 12).

I have 5 cameras configured but all records files are completely black.

Config:

ffmpeg:
  camera:
    camera_1:
        name: camera_1
        host: HostIP
        port: 554
        path: /Preview_01_main
        fps: 20
        username: username
        password: password
        substream:
            port: 554
            path: /Preview_01_sub
            fps: 10

    camera_2:
        name: camera_2
        host: HostIP
        port: 554
        path: /Preview_01_main
        fps: 20
        username: username
        password: password
        substream:
            port: 554
            path: /Preview_01_sub
            fps: 10

    camera_3:
        name: camera_3
        host: HostIP
        port: 554
        path: /Preview_01_main
        fps: 20
        username: username
        password: password
        substream:
            port: 554
            path: /Preview_01_sub
            fps: 10

    camera_4:
        name: camera_4
        host: HostIP
        port: 554
        path: /Preview_01_main
        fps: 20
        username: username
        password: password
        substream:
            port: 554
            path: /Preview_01_sub
            fps: 10

    camera_5:
        name: camera_5
        host: HostIP
        port: 554
        path: /Preview_01_main
        fps: 20
        username: username
        password: password
        substream:
            port: 554
            path: /Preview_01_sub
            fps: 10

        trigger_recorder: true
      camera_5:  # Attach detector to the configured camera_2 above
        fps: 10
        trigger_recorder: true

nvr:
  camera_1:  # Run NVR for camera_1
  camera_2:  # Run NVR for camera_2
  camera_3:  # Run NVR for camera_1
  camera_4:  # Run NVR for camera_2
  camera_5:  # Run NVR for camera_1

The live view is ok, I can see the correct camera immage

Do you get any errors in the browser console? If not, could you play the video in VLC for instance and check the Media Information/Codec Information?

[lio00lio]

Thanks a lot for the answer. If I download the file and check it with VLC, I can see the record section. From VLC I can see:

Sorry, i change the language on VLC in EN to re-share the codec information:

[roflcoopter]

Thanks!

And no errors in the browser console?

[lio00lio]

only this https://github.com/roflcoopter/viseron/issues/832#issuecomment-2467955028

I meant in the browser devtools console, in chrome you can open it with F12

[lio00lio]

No, no error for the networks tab and no mistake in the console, only this on the setTime method:

If it's possible to change your cameras encoding to h264 instead of hevc, please try if that works

[lio00lio]

unlike i cannot do it: https://community.reolink.com/topic/2961/codec-rlc-810a

Reolink cameras mainstream is only h265 and I cannot be changed

[roflcoopter]

Ahh i see, can you run a quick test with the substream instead then? If it still produces black video we can rule out the encoding.

[lio00lio]

with the substream, the file is visible from the web interface. but is in 640p

[lio00lio]

sorry, it is just an issue with the browser, with google chrome last version (compatible with V9 video stream) is working as expected
