Playback Control

This guide provides instructions on how to control the playback of a BlendVision One iframe player, allowing for interaction between the player and your website.

Step 1: Define a Unique ID in the iframe Code​

Include id=”IFRAME_ID” in your iframe code, replacing IFRAME_ID with a unique id of your choice.

<iframe id="IFRAME_ID" src="https://showroom.one.blendvision.com/embed?token={token}" width="640" height="360" allow="autoplay; encrypted-media; clipboard-write" frameborder="0" allowfullscreen></iframe>

<script>
  window.addEventListener('message', event => {
    if (event.data.command === 'ping') {
      Array.from(document.querySelectorAll('iframe')).forEach(iframe =>
        iframe?.contentWindow?.postMessage({ command: 'pong' }, '*')
      );
    }
  });
</script>

Step 2: Control Playback Using Post Message​

Utilize the following post message commands to control your iframe player.

Play​

const bvOnePage = docuement.querySelector('iframe#IFRAME_ID')

bvOnePage.contentWindow.postMessage(

 JSON.stringify({event: 'command', func: 'play', args: []}),

 '*'

)

Pause​

const bvOnePage = docuement.querySelector('iframe#IFRAME_ID')

bvOnePage.contentWindow.postMessage(

 JSON.stringify({event: 'command', func: 'pause', args: []}),

 '*'

)

Seek to a Target Time​

Pass the target time in seconds to the args:[]

const bvOnePage = docuement.querySelector('iframe#IFRAME_ID')

bvOnePage.contentWindow.postMessage(

 JSON.stringify({event: 'command', func: 'seek', args: [12]}), // seek to 12sec.

 '*'

)
