If we require that, I think we should ASSERT on it, instead of the if() below,
which could hide a potential issue in the encoder (producing multiple frames per
buffer), which this validator should catch?

         ASSERT_TRUE(seen_idr_);
         seen_sps_ = seen_pps_ = false;
-        if (!frame_cb_.Run(keyframe))
