// This file contains the class RtpFormatVp8TestHelper. The class is
// responsible for setting up a fake VP8 bitstream according to the
// RTPVideoHeaderVP8 header, and partition information. After initialization,
// an RTPFragmentationHeader is provided so that the tester can create a
// packetizer. The packetizer can then be provided to this helper class, which
// will then extract all packets and compare to the expected outcome.
