record video to file

[mmatiaschek]

record the video from rgb camera to a file in external storage while logging pointCloudData.timestamp & .numPoints and (RecorderActivity line 354) and Pose (RecorderActivity Line 300-306)

i currently see two possibilities to record the pure video from tango api in Java:

1. grab video data from GLSurface or Texture and feed to TextureMovieEncoder similar to grafikas CameraCapture Example https://github.com/google/grafika/blob/master/app/src/main/java/com/android/grafika/CameraCaptureActivity.java
2. OR use the raw frame data from mTango.experimentalConnectOnFrameListener

please use one of this or document if there is a better possibility

Timestamp from Tango appears to always be 0 - maybe this is a solution? https://stackoverflow.com/questions/32986283/how-to-get-frame-timestamp-when-mediacodec-decoder-is-configured-with-surfacetex
