Can you please also share the code/url you would use for embedding jwplayer video in iframe?
1. Here is the code that i added in wplms-customizer.php file in wplms customizer plugin:
add_action('wplms_before_every_unit','wplms_jwplayer_compatibility');
function wplms_jwplayer_compatibility(){
add_shortcode('jwplayer', array('JWP6_Plugin', 'shortcode'));
}
2. used this shortcode :
[jwplayer playlistid="5777"]
5777 is the playlist id that you will create .
All the media is uploaded in the wordpress media library .
