Video Shows Black All Of A Sudden via Our Player Cards



In recent weeks our videos were playing via inline a Tweet. However, in the past 2 weeks we have noticed they are not playing and showing black screen.

This occurs on desktop but is correctly working on mobile devices.

If you view the following on desktop, you will find the issue in above tweet as an example. Any help would be great.

Thanks in advance.


Hi @teachertube. Back in August, we announced that Flash would no longer be available for Player Cards if created after Aug 11, 2015. This change was put into effect for user security and usability on mobile devices.

Your card for was approved on Aug 20, 2015, and therefore would be subject to this rule. Once your player is moved to HTML5, it should work once again.

We make sure that all announcements affecting developers are posted on the Announcements section and Tweeted from @TwitterDev. You may also be interested in more granular changes on our documentation by following API Changelog’s updates here:


Thanks for your feedback. We are on it. :slight_smile:
