Describe the problem

I have multiple Unifi cameras configured (plus a non-unifi camera) all showing in HomeKit. When I view them on an Apple TV, I bring up the preview screen that shows a live feed of all the cameras. I can see in the Homebridge logs that a stream for each camera starts. If I select a camera, the live feed for that camera shows full screen. At that point, streams for other camera stops (as expected). The camera that I'm viewing full screen continues for a few seconds, but then also stops. The camera live feed shows 'No response' in tvOS, but then if I leave it, 30 seconds later a new stream is started automatically and works as expected.

If I disable other Unifi camera, leaving only 1 active, when I view the preview or cameras I see the stream start in Homebridge. When I select to view that remaining Unifi camera full screen, the stream never stops and restarts in this case. The issue only happens when I have multiple Unifi cameras enabled.

I'm running tvOS 17.4, but this has been happening for a while on previous tvOS versions. This issue doesn't happen when using iOS or macOS as only a snapshot image is used for the preview, not a live stream.

Thanks for the report. None of these are issues with HBUP, but rather bugs in tvOS. I experience similar things at times…there’s not much to be done here from an HBUP perspective. You can mitigate it, if you choose to transcode in all cases. For local streaming, you can select the feature option to transcode in all circumstances and that should do the trick and significantly alleviate the issue.

TL;DR: tvOS bugs. It can’t handle the quality level of a UniFi Protect camera and really wants a lower quality transcoded stream. Some versions of tvOS are more capable than others at handling it.
