Media error: Format(s) not supported or source(s) not found

[dstrivelli]

I'm getting very spotty loading of a variety of files. Users in Chrome for mac, Firefox, IE11, and Edge are reporting seeing this error and no functionality.

The native HTML5 video player works just fine, so I'm having a hard time debugging the problem and cannot replicate on my personal machine. What can I do to debug with my users?

[rafa8626]

A Fiddle is a good start point to debug this. Now maybe the way the player is being implemented could be an issue, or maybe (but it entirely sure) the media source itself

[dstrivelli]

The only thing about this is that it seems to work just fine for some users on some machines, and not others on other machines. In my head that would seem to be a codec problem, but if the video also plays on those machines through the native HTML5 player, then I'm sort of thrown.

I'll try to collect a fiddle that demonstrates this, but I'm not sure :-(

Maybe it's then internet bandwidth for what you are describing

[rafa8626]

Or OS versions

[dstrivelli]

I just don't see any clear line between any configuration and the problem. Some users have MacBook Pro running Chrome, some have IE 11 on Windows 10

[rafa8626]

You have to consider that if they have installed other plugins in the browsers that also affects the media being played

[dstrivelli]

Interesting, I'll see what info I can gather along those lines from various affected folks. Thank you for the perspective.

I also have this question。

In editor -> switch on text tab
Add ?_=1 end of video url
Ex: ... mp4="https://video.mp4" ... => ... "mp4="https://video.mp4?_=1" ...
It resolved my problem :)
