Error: FFmpegDemuxer: open context failed

I am loading a video from a NodeJS server via a HTML template using a video tag. Each time the template is loaded these errors occur.
[0515/] MediaEvent: MEDIA_ERROR_LOG_ENTRY {“error”:“FFmpegDemuxer: open context failed”}
The template is then destroyed. All I could find on the topic was the issue is fixed in the next chrome version. I have no issues when loading the HTML file in Chrome version 63.

CEF isn’t built with support for proprietary codecs like mp4 you can use vp8 or vp9.

Thank you!
