live view loading issus in IOS26 PWA or Safari

[gasment]

I'm not sure when the problem started.May be ios 26 or frigate 0.16.2.When go into the live view page，may trigger a infinite loading，unless you switch to other page and come back,live view will work nomaly.this issus both appear with ios PWA and safari，but ios edge
browser works all fine.and it appears only with h265 stream，if I transcode the stream to h264,all clients work fine but lead to loadling slowly.

Methods that have been tried but can not solve:

• add apple_compatibility config in ffmpeg
• change or remove proxy,connect directly
• clear safari data
• update to ios 26.1

any idea to help?

Based on the available documentation, your H.265 stream issue with iOS Safari/PWA is likely related to codec compatibility. The documentation specifically recommends using H.264 instead of H.265 for the best Live view experience(1).

For camera settings, Frigate recommends:

• Video codec: H.264 - provides the most compatible video codec with all Live view technologies and browsers(1)
• Avoid "smart codec" or "+" codec variations like H.264+ or H.265+, as these non-standard codecs remove keyframes(1)

The documentation notes that MSE (which Frigate uses for live view) requires iPhone iOS 17.1+ and has specific codec requirements(1). Firefox only supports H.264 with MSE(1).

Since you mentioned transcoding to H.264 works but loads slowly, you should also adjust your I-frame interval (keyframe interval) to match your camera's frame rate(1). For example, if your stream outputs 20fps, your i-frame interval should be 20(1). Values higher than the frame rate will cause the stream to take longer to begin playback(1).

The apple_compatibility option you tried is specifically for H.265 cameras and "adds compatibility with MacOS and iPhone"(2), but it appears this may not fully resolve the infinite loading issue you're experiencing.

Recommended solution:
Configure your camera to use H.264 codec with an i-frame interval matching your frame rate(1). This should resolve both the compatibility and loading speed issues.

The issue is with iOS 26. See this related discussion: #20406

yes,i have cheaked this discussion，but i never use http3，even I use local ip:5000，the loading issus still exist.
i believe it is the new version os or safari problem，i have meet another safari web video playing issus which will stack on the first frame and make the video never begin playing,untill you clear the safari data ,same problem happen in friagte playback,small probability
