Hello,
I get this Linker Error while building for simulator or device.

Undefined symbols for architecture x86_64:

objc-class-ref in libFFmpegWrapper.a(FFmpegWrapper.o)
"OBJC_CLASS$_FFOutputFile", referenced from:

objc-class-ref in libFFmpegWrapper.a(FFmpegWrapper.o)
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
I have added the following frameworks & libraries
CoreMedia, VideoToolbox, libbz2, libbz, libiconv, libFFmpegWrapper.a

Please help.

@ashutosh-samosa have you found the solution ?

You need to set YES in build Active architecture setting. Everywhere in your project.

@ashutosh-samosa hi, let xcode compile code by including all the ffmpegWrapper/*.m and .h files.
extra libraries: AVFoundation, audioToolbox.
it works for me.

@chienfuchen32 is right. In addition, remove the .pch file in the project. If your FFmpeg libs are grabbed with the latest version, there may be several compile errors to fix.
