Override WordPress Video Dimensions

WordPress comes with its own media player. It supports M4a, MP4, OGG, WebM, FLV, WMV, MP3, WAV and WMA formats. In addition, you can also embed videos from a dozen external sites such as YouTube, Vimeo, etc. WordPress will automatically embed the video when you add it to your post. You can change the dimensions of your videos by overriding the width and the height of the media player.

Edit the functions.php file, and add the following code.

function override_video_dimensions( $out, $pairs, $atts ) {
  $out['width'] = '640';
  $out['height'] = '360';
  return $out;
}
add_filter( 'shortcode_atts_video', 'override_video_dimensions', 10, 3 );

Here’s how to add YouTube videos in WordPress.

YouTube HTML5 Video Player

YouTube now defaults to HTML5 video player instead of Flash. The new player takes advantage of MediaSource extensions for its Adaptive Bitrate streaming allowing viewers to quickly and seamlessly switch resolutions. The new player also uses a new video codec called VP9 which gives you higher resolution with low bandwidth. YouTube will also start using WebRTC for recording videos and for live streaming capabilities. Read more.
