This project does not produce a libplugins_multimedia_ffmpegmediaplugin_arm64-v8a.so file that produces this error.

Hi @tanersener I resolved this issue by using ffmpeg 7.0 version of library. Qt has inbuilt libraries of ffmpeg in there latest version of multimedia and Qt Documentation says that only ffmpeg 7.1 version is supported in the latest version of qt.
Note :- use only static library in mac or ios (this works fine with me).
