Type: Bug Report
When adding multiple media players, not all load the video(s)

Reproduce the problem:

  1. Create a page with 6 kendo UI MediaPlayers and stream 6 videos (YouTube or live HTTP stream). This should work fine.
  2. Create a page with more than 6 kendo UI MediaPlayers and stream that many videos (YouTube or live HTTP stream). This will not work properly

In kendo dojo (https://dojo.telerik.com/iLASIwUw and KendoError.jpg) 1 or more of the MediaPlayers give this error: "Your browser does not currently recognize any of the video formats available. "

Using my own application (see attached page zip and CustomError.jpg) I create multiple MediaPlayers. The first 6 work perfectly. Every video I add after the first 6 just shows a white screen. No errors are given.

I did note, when using my own example, that when one of the 6 working streams is closed, one of the 4 not working MediaPlayers starts playing, i.e. no more than 6 running MediaPlayers at any one time.


For the kendo dojo example, each MediaPlayer is attempting to stream from the same YouTube video.

For my example, each MediaPlayer is streaming from a different HTTP stream.


What can I do to play more than 6 MediaPlayers at once on one HTML page?

Kind regards,

Keyan Monadjem

Hello Amitesh,

Thanks for reporting this. I have logged an issue about the problem that you can track at:


The GitHub item can be found at:


We are not aware of a workaround at the moment as the issue seems to be caused by a call to the YouTube API, which requires further research.

I also updated your Telerik points due to your bug report.
