You can also do this manually by adding the following parameters into your embed code:
If you have more than one video autoplaying on a particular page, you will also need to include this parameter:
So, for example, if you were embedding two autoplay, looping, videos on a page, the embed code for each would look like this:
Some browsers specifically block autoplay. In these cases, your video will revert back to the original thumbnail and controls, requiring viewers to select play to start playback.
Safari version 11+ (Desktop)
Policy: Autoplaying videos must be muted. Viewers can choose to block or allow unmuted autoplay for specific domains on their setup
Chrome version 66+ (Desktop/Mobile)
Policy: Autoplaying videos must be muted. Videos that are frequently visited by the viewer are permitted to autoplay with sound
Policy: Autoplaying videos must be muted.
Firefox 66+ (Desktop/Mobile)
Policy: Firefox now blocks videos with sound from playing automatically. This change is being gradually rolled out to users in Quantum version 66. Viewers can choose to block or allow unmuted autoplay for specific domains on their setup
There is no way to stop these autoplay restrictions; however, you can mute your video to ensure autoplay is always honored. Just add one of the following parameters to the end of the player URL in your embed code:
This parameter automatically disables all elements in the player (play bar, buttons, etc), autoplays, loops, and mutes your video on load.
This parameter will automatically mute your video on load. Once your video plays, viewers can manually unmute by clicking on the volume bar within the player.
Both of these parameters will force your video to load as muted in all browsers. Videos without audio tracks will not be considered muted by browsers. In order to bypass autoplay restrictions, you must use one of the embed parameters above.
If your webpage has permission to autoplay but your video is still not playing, you may need to add the:
parameter to the iframe, and any iframe in your webpage that the player is contained within.
Here is an example using the iframe:
