Depending upon the web browser and platform used when viewing streaming audio and video, you may at times receive some unexpected results! It often surprises people that there are actually many more problems encountered when dealing with audio than with video!

So what action should be taken if you receive a message like the following when attempting to stream from CourseMedia or any other streaming system?

Normally, we suggest making sure that you are using a modern web browser which supports streaming protocols via the chosen playback technology through the Media Source Extensions API (MSE) and if you still encounter problems – to ensure you have Adobe Flash Player installed and enabled for your browser. Visiting http://supportdetails.com/ is a good way to get an overview of what is enabled based upon the web browser used and you can send this information to your support team.

At OTL, we use JWPlayer 7 (JS MSE or Flash Player) and Adobe Media Server 5 (HLS protocol) for all of our web-based CourseMedia streams in order to cover most technology possibilities – but there are many problems which still exist regardless of platform. Why HLS? Because that is the protocol which works best across most active platforms today. Additionally, our streaming server technology is getting on in age so does not support every single format out there when performing HLS streams. Hopefully we will be able to adopt new streaming technology soon which will remedy much of our current issues.

We strongly suggest using either Google Chrome or Mozilla Firefox when encountering streaming issues in CourseMedia or any web-based application.

Additionally, Microsoft is no longer updating Internet Explorer and instead is focusing on their new browser named Edge. Microsoft Edge has its own issues as well – it’s quite buggy and has a lot of catching up to do. We will continue to test against this web browser as Microsoft aligns it more closely to accepted standards.
