I downvoted you because every comment from you makes you more of an ass then the previous. You spouted your nonsense opinion and then refused to even elaborate it - either you are here to troll or you have no arguments. However in the end you are just a rude ass.
I use bubble upnp. If you share the yt link to it, you can cast the video to your Chromecast devices https://play.google.com/store/apps/details?id=com.bubblesoft.android.bubbleupnp
