In QualityAnalyzingVideoEncoder all encoded images that belongs to
unrelated simulcast streams will be marked as to be discarded. So
to support simulcast streams QualityAnalyzingVideoDecoder have to return
black frames when all encoded images in received concatenated encoded
image are marked as to be discarded. Also QualityAnalyzingVideoDecoder
shouldn't pass such encoded image into VideoQualityAnalyzerInterface.
