Microsoft Edge: Video Couldn't Be Decoded HELP

Just to add, (as there is no edit function) Microsoft has a decision to make,

1) Pay part of their profits to HEVC

2) Use VP9X which is itself a lot of work as it was only meant for Google's internal use, Netflix has done some work in adapting it to their video production chain.

3) Wait for AV1 for which it is big backer.

Edge (win 10 browser) does now have software VP9 support and there is some hardware decoding support for VP9 in the GPU used on the Xbox so it could do a mix of software and partial hardware decoding as MS owns all the software/hardware stack on the Xbox.

They probably should go with VP9 to be on the safe side as the time table for AV1 is too aggressive/optimistic in my opinion.

Man, I guess the Microsoft Edge don't support all the video players or the all video formats, sometimes I have these problems too. Maybe the problem is the website, or, like I said, the Edge.

What video file types are they? The Xbox360 has some limitations on what it can decode internally. That may be why they work streaming from Windows Media Player, as the decoding action is done by WMP.

There is specific info on what the 360 supports for video files here: https://support.xbox.com/en-US/xbox-360/console/audio-video-playback-faq

No one said you couldn't watch video's on the edge browser on xbox one. The problem is there are no thumbnails, no like or dislike button and everything takes 20 seconds to load. I'm sure there are a few more issues I just cant think of at the moment.
Or you are talking about edge on your computer and not the xbox one?

Same here. Everything was fine up until the latest update. Now, the video will start but shortly after stops with the "Error: Video cannot be decoded" message.
