HTML5 track doesn't work for me. I have tried for a couple of hours and tested in FF, Chrome and Opera. Here are the code and .vtt file.<!DOCTYPE html><html lang="en"><head> <title>Video HTML5</title><style> video { box-shadow: 6px 6px 3px #888888; border: 1px solid grey; padding: 8px; allowfullscreen: true; } </style> </head><body><div class="video"> <video id="video01" controls preload="auto" width="400" height="300" poster="/pics/dnskrapan1.jpg" data-setup='{"autoplay": false}'> <source src="/movies/testbild.mp4"
