4 years ago Hey,
1) First you need to get permissions for external storage.
if (ContextCompat.checkSelfPermission(getActivity(), Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) { ActivityCompat.requestPermissions(getActivity(), new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, PERMISSION_RQ);
}2) Pay attention to the oder - first wait for ffmpeg lib to finish loading - only then start any commands
