- To enable loop on a video, only setting the 'loop' URL parameter to 1 will not work anymore. We also need to set the playlist parameter to the video ID. - Sound is no longer allowed in autoplay because of new autoplay policies of most browsers. To make autoplay work, the video must be explicitely muted. closes odoo/odoo#34323 Signed-off-by: Quentin Smetz (qsm) <qsm@odoo.com>
