VideoProgressListener

All Known Implementing Classes:

EchoingProgressListener
```
public interface VideoProgressListener
```
A VideoProgressListener is meant to share progress from potentially any number of EncoderProgressListeners. Because it would be hard to determine the overall status by just tracking successive progress from ffmpeg, an onBbegin and onComplete have been added.
