Steps to reproduce

Hi,

I am using WebGL (Blend4Web) in conjunction with ogvjs for software decoding WebM. I am experiencing severe performance issues on a reasonably powerful Desktop. I know that this works on my WIndows 10 PC at home, but at work there are performance issues.

However, on Chrome it works perfectly…

A working example which I have pushed to GitHub if anyone is interested;

https://github.com/YateleySchool/YSMap3d

I find that when I use the npm software package http-server running on port 8080 and connect and then visit the video-test.html file I have the following issues;

The video overlay on the right hand side, the iframe of the official ogv.js demo, runs perfectly on Chrome. However, on Edge/IE11 browser at my workplace computer it runs really very slowly. So slow that you cannot use it.

The video overlay on the left hand side appears to start playing on Edge/IE11 at my workplace, but seems to stop very soon after the start of the video.

Please note that this works fine in Chrome browser and Firefox on the same computer.

I may be pushing Edge/IE11 too far by running 3d WebGL and video decoding at the same time.

Thanks,

Andrew
