test the case of "reading video file in exported folder", it work.
You can try by these steps. 1. download test file (movie.ogg) from gonzdevour's link http://www.w3schools.com/html5/movie.ogg 2. in capx, assign src url to "movie.ogg", then export capx. 3. put movie.ogg downloaded (at step1) into export folder (at step2) 4. open the index.html in exported folder. It works in my testing.
You can also put it in a video folder by entering:
2b. in capx, assign src url to "video/movie.ogg", then export capx.
Then just make a folder named video and put that with all movies into your export folder.
I create intro with video file all display very nice but when i put space button to go to next layout didnt work. I try with conditions'on ended' and 'is ended' go to another layout and dont work last frame of movie are displaying and freezes
