# Changes in MixedReality sample

MixedReality sample has been modified and uses the new Video Stream (<span style="color: rgb(230, 126, 35);">[Video Stream](https://doc316en.candera.eu/link/646#bkmrk-video-stream)</span>) functionalities. Furthermore, the intro video is played in a infinite loop instead of once, which is realized with the new condition behavior (<span style="color: rgb(230, 126, 35);">[Check Video State](https://doc316en.candera.eu/link/597#bkmrk-check-video-state)</span>) and action behavior (<span style="color: rgb(230, 126, 35);">[Configure and Play Stream](https://doc316en.candera.eu/link/582#bkmrk-configure-and-play-s)</span>).
