And I try to embed it as follows :
<video src="helios.mp4" controls="controls">Get a better browser!</video>
However, Chrome doesn’t play the video, only offers to download it (same as it did before I converted the video). Firefox has the same problem.
I’ve tested and other mp4 files (from my phone) play just fine.
What’s the problem ? Did I convert it wrong ?
