Might be releated to this

From the log, you are using 5K resolution, but it seems that the crashed thread is related to Camera, the crash comes from 1 Dispatch queue: org.webrtc.RTCDispatcherCaptureSession, and it is related to setting the minimum frame rate.

This is a tricky issue, I can't reproduce this error on my computer, there is an idea, if you try to use https://github.com/webrtc-sdk/webrtc@m104_release to compile the debug framework of m1 mac in Native, you should be able to locate the code and line number in libwebrtc at the time of the crash

@cloudwebrtc Thanks for the prompt reply.

it is related to setting the minimum frame rate.

I was using OBS, finecam virtual cams on the machine and I also had continuity camera from my iphone hooked in to this M1 machine. I will further inspect to see I can further debug.

to compile the debug framework of m1 mac in Native

I might be also Compiling framework at some point when have more time.

As discussed in Slack, this issue may be related to virtual cameras

[JasCodes]

Guys, I test on my mac studio with physical camera. Its still cause the crash. Here I am making sure before connnecting I use physical camera.

Please find below logs.

AVCaptureDALDevice seems to missing a frameRate setting method, the fps of the virtual camera may depend on the OBS output, so I created this PR to skip the setting and it works fine

@cloudwebrtc Awesome mate!! I will tryp and report back.

[cloudwebrtc]

I'm recompiling .xframework and publishing new one to cocoapods, and in about an hour I can create a PR in lk-flutter-sdk to fix this issue.
