You can have a QByteArray of the byte stream, provide a QBuffer from the QByteArray and pass the buffer as the stream for a QMediaPlayer :

databuf = QByteArray(reinterpret_cast<char*>(array), size);
QBuffer mediaStream(&databuf);

player = new QMediaPlayer;
player->setMedia(QMediaContent(), &buffer);

videoWidget = new QVideoWidget;
player->setVideoOutput(videoWidget);
videoWidget->show();

player->play();
