I have done this by lipo command such as lipo -create ./dylib_intel/libavcodec.58.dylib ./dylib_arm/libavcodec.58.dylib -output ./dylib_universal/libavcodec.58.dylib

I found the solution. I can just using xattr -c on my app. Then this issue gone.

Still got the same problem now -_-.....

At last I add additional import in my .mm file to fix this issue. But I don't know why I don't need to do this before Xcode update.

Thanks, got it.

For additional reference, I was building the ffmpeg library for Arm. The Intel part I got from my previous owner directly. I just using the same build config got from the original owner to build the Arm build and using lipo to combine these two library into one to be used in my app. I am wondering are there something I am missing when I build the Arm version. Are there any possible hint to find the solution?

I used otool -l to get some information on my lib. Does anybody know why the load path will be different within the same project?
