Preloading mp4 files

I have a preloading scene called boot.js which runs first and loads all my assets. I’ve used it before just fine until now. The game I’m working on right now uses mp4 files, like so:

this.load.video('video', 'video/video.mp4', 'loadeddata', false, true);

The problem I’m having is that the preloader gets stuck and it does not advance to the next scene like it suppose to do, I’m not getting any errors in my console. Any pointers or tips on how to fix the issue. The mp4 files where converted using handbrake with “web optimized” and “align a/v” start checked. Also the files have no audio. I’m loading roughly 27 files but the biggest one is 355KB.

Thanks!!!
