VT: provide last cvo value if it's not present.



[Problem] video has been rotated wrongly for
  very short time then recovered quickly.
[Cause] CCodec requires rotation value for every frame.
  if not present, it is showing default rotation.
[Solution] Provides last cvo value if cvo can not
  be parsed due to packet loss.
