Video Editing For Android

i want to build a app having video editing feature.

These are what I need:

• Mix a new sound track(mp3) into a mp4.
• Adjust sound volume proportion for original mp4 sound track and the new sound track.
• Generate mp4 from images.
• Remove some frames from mp4.

I've found FFMEPG but it's quite complicated. Is there a easier one?

1.Mix a new sound track into a mp4.

2.Adjust sound volume proportion for original mp4 sound track and the new sound track.

--> Use MP4Parser for adding and removing audio tracks.

3.Generate mp4 from images.

4.Remove some frames from mp4.

--> Use JCodec to get all frames from mp4 or create mp4 from frames,
