FFMpeg for Android doesn't work on Genymotion emulator

We can run and compress videos using ffmpeg on a real android device, but when we try to use it on Genymotion emulator it gives some errors and doesn't work.

We do chmod in the / system / bin folder and copy it / data / data / app.

This is what we see trying to do only the -version command on logcat after asking for errors on cmd:

[Ljava.lang.String; @ 52a20e6c / data / data / com.video.myapp / ffmpeg [1]: syntax error: '?? 4 'unexpected

[/data/data/com.video.myapp/ffmpeg, -version]

Do you know what could be?
