@ashutosh-samosa have you found the solution ?

commando24 commented 6 years ago

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.
