issue video streaming over wifi and web with iphone X , not with iphone 6 plus

Hello,

I have a problem to receive video stream from my PI camera works with RAPSBERRY 3. The IP camera address is http:// 192.168.1.27 :8080/ ?action=stream.

The Raspberry PI3 send one frame all 2seconds.

I use an iphone X ( ios 11.3) with SAFARI or FIREFOX and also a laptop with FIREFOX browser.

Important : With my laptop all is OK . I receive all frames from my IP camera (one frame all 2 seconds.)

But with my Iphone X, I don’t receive correctly all frames. I received only the 1st frame and that’s all. To update , I have to press each time on the circle arrow at the top right of the SAFARI browser.

With another Iphone x , i have the same issue.

I don’t understand why ? ( I have the same problem with FIREFOX browser).

I didn’t have this problem with my old IPHONE 6 plus ( IOS 11.2.6). I receive correctly all frames (one frame all 2 seconds).

it seems that there is a regression between iphone 6 plus and the new iphone X

I need your help to fix this problem on iphone X.

Thanks in advance.
