I have tried this: Dynamically using the first frame as poster in HTML5 video?
to get a thumbnail of a video in HTML5 using popcorn.js on IOS, but it didn't work. the 'canplayall' event didn't fire untill I clicked play on the video.
and then, there was no poster attribute added to the video.
On google chrome (PC) it worked 100%.
Any advice?
