Why tutorial-video-textures can't run correctly on iPhone and Android?

I tried to run the example on my iPhone and my Android,
but the TV screens were black and did not show the video correctly.
Can anybody help me?


Works fine on my Samsung S7 with the latest Brave browser. What model of phones and browser versions are you using?

iPhone X Safari (iOS 12.0),and default browser on Meizu ( a chinese cellphone brand, using android)

probably the browaer safari doesnt work well with iframes actually i dont think it works at all on moble but i could be wrong

I don’t have an iPhone I can test with. I would try to connect to the phon browsers to a web devtool and check the console log:
