then i find, when i close the full screen mode by click X , and they click play, the subtitles shows.
it seems the ios can not load the subtitle at the first time, so need to exit the full screen mode, and then click play , and by doing that, the subtitles shows up.

but it is very bad experience for visitors, hope video.js can fix this compatibaility problem.

somewhere on the video.js file, very difficult to find

problem solved

Thanks very much, buy this way, it only support one subtitle, am i right?
