I am using ffmpeg for android (using the gradle plugin 'com.writingminds:FFmpegAndroid:0.3.2') and I am trying to crop a video to a 16:9 (w:h) ratio. The original video is 1080:1920 (w:h).
When I execute the command I get an IOException No such file or directory.

The command I am using:

```
-i /storage/emulated/0/Movies/MyApp/result_joined.mp4 -vf crop=1080:607   -preset ultrafast /storage/emulated/0/Movies/MyApp/result_cropped.mp4

```

The exception:

```
java.io.IOException: Error running exec(). Command: 
[/data/user/0/my.package.name/files/ffmpeg, -i, /storage/emulated/0/Movies/MyApp/result_joined.mp4, -vf, crop=1080:607, -preset, ultrafast, /storage/emulated/0/Movies/MyApp/result_cropped.mp4] Working Directory: null Environment: null
Caused by: java.io.IOException: No such file or directory

```

After searching several stack overflow questions with no help.
I also tried to save files to internal storage instead of external storage. Same result

Any help?
