// QualityAnalyzingVideoDecoder is used to wrap origin video decoder and inject
// VideoQualityAnalyzerInterface before and after decoder.
//
// QualityAnalyzingVideoDecoder propagates all calls to the origin decoder.
// It registers its own DecodedImageCallback in the origin decoder and will
// store user specified callback inside itself.
//
// When Decode(...) will be invoked, quality decoder first will extract frame id
// from passed EncodedImage with EncodedImageIdExtracor that was specified in
// constructor, then will call video quality analyzer, with correct
// EncodedImage and only then will pass image to origin decoder.
//
// When origin decoder decodes the image it will call quality decoder's special
// callback, where video analyzer will be called again and then decoded frame
// will be passed to origin callback, provided by user.
//
// Quality decoder registers its own callback in origin decoder, at the same
// time the user registers their callback in quality decoder.
