[yinhaojun]

  implementation 'com.github.wseemann:FFmpegMediaMetadataRetriever-core:1.0.15'
  implementation 'com.github.wseemann:FFmpegMediaMetadataRetriever-native:1.0.15'

and i add libavformat.so,libswscale.so, libavcodec.so and libavutil.so in jniLibs. But when i create FFmpegMediaMetadataRetriever, it crashed!

If i remove implementation 'com.github.wseemann:FFmpegMediaMetadataRetriever-native:1.0.15' and only add .so to jniLibs, it also crashed.
