First, what's wrong with FFmpegFrameGrabber?

Looking at your ModifiedFrameGrabber.java file, it seems you would like to have 
the ability to seek within a stream. I have added this feature in the latest 
release, as the FFmpegFrameGrabber.setTimestamp() method. Let me know if it 
works well for you or not, thank you!
