Hi. First of all, thank you for your excellent project. I’m trying to use your project as part of my robot project. When I downloaded and ran the prebuilt RPiOS version you released, it worked very well without any major issues. Here’s the log from that run:

However, when I downloaded the source code and built it myself, a segmentation fault occurred even though I used the same command. Here’s the log from that case:

Could I ask for some help regarding this issue?

Ahh. For now, I’ve successfully run the self-built code by building the source code directly on a real Raspberry Pi Zero 2W, instead of using the cross-build environment described in [https://github.com/TzuHuanTai/RaspberryPi-WebRTC/blob/main/doc/SETUP_ARM64_ENV.md ]. I’m not sure what the problem was, but anyway, it seems like the urgent issue is resolved for now.
