Is there a way to set the default HTML5-Video volume?

Question

HTML5 videos always start at 100% volume.

How can I make them start at 50% volume?

Answer 1

You can affect the volume property of the <video> element as follows:

document.getElementsByTagName('video')[0].volume = 0.5; 

If using jQuery then you can use their prop method to alter the volume in a jQuery collection object like so:

$("video").prop("volume", 0.5); 

This will alter all DOM elements in the collection.
