Lightest possible configuration for record-only use case

[Suxsem]

Hi all!

I'm searching for a lightweight nvr for 7x24 recording of my 5 cameras.
My main goal is to keep the CPU usage al lower as possible.

Is it possible to disable all motion/object detection features and only use Viseron for save the rtsp stream to the disk and review them using the web interface?
Is it possible to DISABLE decoding of the stream during normal operation?

Thank you!

[roflcoopter]

Hello!

Yes you can use Viseron without using motion or object detection.
You would have to use the latest v3 beta for that.

I am unsure if Viseron still does the decoding.
Would be great if you could test it out and we can work from there

[roflcoopter]

Ahh my bad, set the path and port to the same as for the mainstream.

[Suxsem]

thank you but unfortunately I get the same error :(

[roflcoopter]

Hmm, does the camera only allow one stream at a time then maybe?

[Suxsem]

no no I can connect from multiple clients without issue

[roflcoopter]

Can you show me your full config?

Just tested again and it is working fine for me (except for the stream restarting every now and then as i mentioned before)

[Suxsem]

sorry I tested again and now the error is gone, strange. nonetheless I'm still getting 100% CPU load:

I didn't change the config (#828 (reply in thread))

thank you!

[roflcoopter]

Sorry for the late reply.

Can you enable debug logs and restart Viseron?
Interested in seeing the generated commands.

logger:
  default_level: debug

I'd be interested in this functionality as well - but the key thing is that viseron is set up to do the decoding for the fps=1 for the thumbnails/image view. That's going to force full decoding.

I think the request here could be 'can that portion be shut off'? Basically disable the '-vf fps' portion of the ffmpeg commands - knowing that it will break the main camera view and the "snapshot" based live view. (HLS I'd expect would continue to work fine.)

(Functionally, that main camera view could just do an on-demand frame extraction from the most recent recording, but that's a whole separate discussion.)

[roflcoopter]

Just took a deeper look at this and it actually seems pretty simple.
Should have a something for you guys to test in a day or two.

@Suxsem are you still interested or have you found other solutions?

[Suxsem]

hi @roflcoopter , I'm absolutely still interested, not other solutions are good enough for this use case, thanks!

[roflcoopter]

@Suxsem @nneul
When dev is finished building you can test the new config option record_only

You set it for each camera that you want it enabled for:

ffmpeg:
  camera:
    camera_one:
      name: Camera 1
      host: camera1.lan
      ...etc
      record_only: true

If you want the still image in the frontend to still work even tho Viseron is not reading frames you can configure still_image and Viseron will pull snapshots from that URL instead of the stream

[nneul]

@roflcoopter

Still image working nicely! I set up a simple web script endpoint on my host system that ran single frame extract from latest m4s. The "live view" does not function though as it tries to do the mjpeg stream. Might want to consider a fallback of

if record_only and still_image:  
   .../still_image_reload       { page that displays full size still image with a refresh like the main page }
else
   .../mjpeg_stream

or just hide that button if record_only.

Additional idea for functionality:

  still_image:
      raw_command: ......

Essentially like you already have for the ffmpeg stream - but a command to be able to extract a single raw frame. In my case, all I did was equivalent of: rm -f frame.jpg; cat init.mp4 <latest>.m4s | ffmpeg -i - -frames:v 1 frame.jpg

[nneul]

ANother piece that would be useful would be option to ask viseron to copy the index.m3u8 to the destination segments tree when running in record_only mode, then I wouldn't need to map /tmp to host filesystem to access.

[nneul]

Working so far. Haven't tried the still function yet, but HLS is definitely still working, and overall cpu consumption way down.

I am getting these every so often though, but they may be unrelated:

Hi @roflcoopter sorry for the long delay before testing, I'm surely missing something here but I don't get any recording ("No recordings for camera-avanti-sx") and I get a red dot in the top right corner of the camera card.

Is anything needed for enabling recording? Thank you

edit: I'm seeing the /segments folder being populated, but the /recordings/camera_1 folder is still empty

where I have /data/segments mapped to /segments inside the container

[Suxsem]

many thanks! Just found the dev docs (https://dev--viseron.netlify.app/docs/documentation/configuration/recordings), quite helpfull! Last thing missing I think is the live view. Let me propose an idea, why not use a realtime streaming protocol like WebRTC or MSE? My current "live view" webpage is based on (https://github.com/AlexxIT/go2rtc). It basically allow to view a realtime rtsp stream in the browser. h264 and h265 are supported in virtually any browser so no transcoding is needed. Just my 2 cents!

[roflcoopter]

Yes that is my plan for v3.1

Cant give any exact estimates on when that can be released tho, not sure how complex that will be to implement.

[Suxsem]

Great, thanks
