WordPress Speed Up Service | WordPress Website Maintenance Packages Reply To: A way to change video SRC priority and order? Want to list WebM first, then MP4, by Yes, I put it in the functions file. I added both pieces of media – the mp4 and the webm, via the media editor in the post. It seemed to be the only way I could “connect” them to each other so they’d be two sources for the same video instead of two separate videos. Here’s my code with the video shortlink: [video width="450" height="253" webm="https://www.heiseheise.com/blog/wp-content/uploads/2017/10/zach_on_water_elevator.webm" mp4="https://www.heiseheise.com/blog/wp-content/uploads/2017/10/zach_on_water_elevator.mp4"][/video] The output in the HTML looks like this, though: <video id="wp_mep_1" preload="none" src="https://www.heiseheise.com/blog/wp-content/uploads/2017/10/zach_on_water_elevator.mp4" height="253" width="450"> <source src="https://www.heiseheise.com/blog/wp-content/uploads/2017/10/zach_on_water_elevator.mp4" type="video/mp4"> <source src="https://www.heiseheise.com/blog/wp-content/uploads/2017/10/zach_on_water_elevator.webm" type="video/webm"> <object type="application/x-shockwave-flash" data="https://www.heiseheise.com/blog/wp-content/plugins/media-element-html5-video-and-audio-player/mediaelement/flashmediaelement.swf" height="253" width="450"> <param name="movie" value="https://www.heiseheise.com/blog/wp-content/plugins/media-element-html5-video-and-audio-player/mediaelement/flashmediaelement.swf"> <param name="flashvars" value="controls=true&file=https://www.heiseheise.com/blog/wp-content/uploads/2017/10/zach_on_water_elevator.mp4"> </object> </video> Reply To: A way to change video SRC priority and order?
