Recordings playback not working

[itlists]

Hello, I have a simple deployment with 1 camera for testing. Live view is working, along with recording. The config file is just the template with cam login info and stream url added.

Between Main and Substream - which stream does Viseron record and which stream does it show in live view?

There are recordings for some motion events but when trying to view any recording, this error is shown: "Playback cannot continue. No available working or supported playlists."

Screenshots attached.

I now have this issue. I had reolink cameras and changed to hikvision and now I can see the capture, play the live video but there are no longer any workable recordings. I suspect it's a video format issue but the details seem to be shown.

The main stream is recorded and the substream is used for detections. If you don't setup go2rtc the substream is used for the live stream

Do you guys get any errors in the browser console?

What does it say in the Console window?

There is a lot in there, what should I look for to filter ?

All thumbnails for recording work fine as does the endpoint to http://localhost:5173/files/thumbnails/camera_3/196.jpg. But it seems like HLS can't play files that are actually stored on the storage. This is camera-specific; I've only experienced this with Uniview cameras.

Have you seen the logs?

I believe this is caused by codec, try forcing the codec for your recorder under camera identifier to use aac codec like this:

    camera_3:
      name: UNIVIEW Uho-S2E
      host: localhost
      port: 8554
      path: /camera_3
      recorder:
        audio_codec: aac # Force audio to be encoded as AAC instead of transcoding from pcm_mulaw

My problem was solved with this, because in the log there was a WARNING:

2025-12-20 17:39:03.914 [WARNING ] [viseron.components.ffmpeg.stream.camera_3] - Container mp4 does not support pcm_mulaw audio codec. Audio will be transcoded as aac., message repeated 2 times

[kaburagisec]

https://aws.amazon.com/what-is/video-transcoding/

[itlists]

Therefore, you need to transcode to h264 in the HLS player, your h265 is only valid in your own NVR. In this case..

Added codec: h264 but same issue for playback, same error in web console.

[itlists]

Any other suggestions to try? Feels like its almost there...

[kaburagisec]

I am 100% sure your camera is Uniview, same as mine. But my problem was solved with my previous aac settings.

Now try purging all data in the container (related to viseron), and rebuilding it. And try to look in the Log (in container) to see if there is a warning from FFMPEG if you use its components.

[itlists]

I have GeoVision cameras, seems to use the same webUI. Most of these cams are manufactured by a couple of companies anyway.
Ok, I'll re-install the container. Not sure how to purge and rebuild since this is running on an unRaid server.
There are plenty of warnings in the log though, I think these cameras don't conform fully to h264/h265 specs?

@kaburagisec Recording playback is working (tested with 1 clip)! Thank you very much for your persistent help :)
Now to do the hard part - setup detections and complete the setup.

Remember the Recordings page is only for event recording, continuous recording is on the Timeline page.
