This project is work for android and iOS, so I use a CAEAGLLayer to present live video which is 60fps. All code work well at iPhone11 and older devices. But at iPhone 12 and iPhone 13, it becomes strange.
The layer drops some frames. I profile with Instrument and find some drawable are waited more than 1/60 second. And after I turn on Screen Recorder, it work well. All drawables are waited less than 1/60 second. The layer present video with 60fps. After I turn off the screen recorder, it didn't work again.
Is there anyone can tell me what happened and how to workaround it?
