Hello,
I have placed a video showcase in my page. This displays well, also in the rendering when checking cross browsers. But loading it on the iPhone5s, the video doesn’t play (browser safari) and loads really slow. What is the problem with that?
The mb.YTPlayer doesn’t work on any mobile devices (iOs, Android, Windows Phone, etc.) due to restrictions applied by the vendors on media controls via javascript. Adding a background image to the body as mobile devices fallback is a good practice and it will also prevent unwanted white flickering on desktop browsers when the video is buffering. The theme does display a placeholder image in mobile devices.
There are some alternate solutions provided in these threads –
