Since this is used only in RTCVideoDecoderBridgeTv::Decode, you can merge this
method into Decode.

Done.

   // We call the decode complete callback function to notify libjingle that
   // decoding is finished. In addition, this also reports back to libjingle that
   // the particular video frame with |timestamp| is correctly rendered to
   // libjingle, so that it can generate proper stats.
