MP4 captions not working in HTML5 player
I implemented the basic setup of JW player, and have found that embedded MP4 captions aren't working in Firefox or Chrome. They do work in IE8. After changing the "primary" parameter to be "flash", the captions work in FF and Chrome. The captions work in the HTML5 player if I supply them as an external file, but extracting the captions from all our videos isn't really an option for us.
I've implemented a crossdomain.xml and the CORS header on my local environment as well, although it still doesn't work when I download a copy of the video to my machine and load it into the HTML5 player.
Any thoughts? Thanks!
