Asset Preview

You can preview your asset in the within the Uplynk platform. This allows you to test and verify your asset, including URL parameters, before you actually try it in a production environment.

In conjunction with the developer tools built into the web browser, you can view the actual HTTP requests for playback using your desired URL parameters and the returned manifests.

Test Video Playback in the Uplynk CMS

To playback an asset in the Uplynk CMS:

  1. Go to the asset details page.
  1. At the top-right, observe the image under Asset Preview and hover the cursor over the image.
  1. If there is no Play icon in the image, the poster image is being displayed. To switch to the video player, move your cursor over the image and a button with Show Player will appear (if it doesn't click on the image to force CMS window focus). Click the Show Player button and the Play icon will appear on the image.
  2. Enter any desired Uplynk URL parameters in the Params box and click the Reload Player w/ Params button to its right. Uplynk URL parameters are described in Customizing Playback (Playback Customization Parameters).
  1. Click the Play icon on the image.
