Aditional information

I also tried a different rtsp stream directly: Still got:

Hi there, I am getting as well broken pipe errors, I tried several rtsp test streams, however all with the same result. Is there an approach that works with the latest Protect versions? thanks all for hints.

[msa0311]

Would be interesting for me to know as well!

[kloknibor]

did you guys try the dev container? this works somewhat

[cakysk]

yep... I'm running all my tests with DEV container.. is there an online RSTP stream that works and can be used for testing?

[msa0311]

yes, the dev container works fine for me! Thanks!

Would be great if you could make this work with latest protect version somehow. Its so sad that this isnt a native feature from unifi protect.

Is there a way to donate for this project?

I just want to chime in and say that the dev docker image (keshavdv/unifi-cam-proxy:dev) works like a charm. :tada:

• I downgraded to protect 2.6.3 to get the qr page going because I had no "Add" button in the UI: https://{PROTECT_IP}/proxy/protect/api/cameras/qr
• I created the docker-compose file with the specific details for my cameras (https://github.com/mouldybread/DCS-6100LH)
• I upgraded protect to latest version 2.8.28.

I followed the documentation for everything else: https://unifi-cam-proxy.com/

I can confirm that it is working also for me.. in the end the issue was that I had (on camera) h264 profile set to 'High Profile', once I set it to 'Main Profile', all started to work. Only issue I have right now, is time.. that is out of sync.

The dev is not working for me. I have reolink cams. Using docker-compose and specifying reolink I get the error that ' reolink' is not a valid option. Somewhere a space is being added.

When I try the options for reolink with the --fmpeg options I either get the broken pip error or a bad cseq error.

When using the dev image my protect app on my dream machine is randomly restarting every couple of minutes.

I experienced the same issue and running the dev image resolved the broken pipe error.

today i installed clean debian 12 and installed docker with unifi-proxy. I got a broken pipe error. Details attached I am using UnifiProtect 2.8.35 and Dahua Cameras. Using VLC rstp stream is working unifiproxy.txt Can u help me :)?

Actually after changing to dev the image is displayed but there is a problem with time synchronization, it is impossible to play the recorded video - playback does not work and the time on the preview jumps very strangely
