Listen to video buffer data

[fernando140alto]

I'm currently using a listener to check if there's enough buffer like so:

      if (targetRef.readyState > targetRef.HAVE_FUTURE_DATA) {
        keepPlaying();
      } else { stopPlaying(); }

However this property willl only listen to audio data and not video data.

Audio is being buffered before video causing audio to keep playing without video.

Is it a way to listen the current video buffer data?

Thanks for the great work with the package!
