"Video format not supported" error (but only when mp4 is linked to via external URL)

I have an mp4 video that I want to use as an Interactive Video (H5P was just updated to the latest version afaik) in Moodle (3.5.3). When I upload the mp4, the video displays. When I link to the video via external URL, I get the "Video format not supported" error. NOTE: I'm using the SAME mp4 file; the only difference is uploading the mp4 vs linking to it (http/https seems to make no difference, either).

I get seemingly-identical PHP errors with both methods:

Hi jcm3,

The error message does not look like it points to the H5P content or plugin.

The issue you are experiencing is an after effect of adding C.O.R.S., accessibility is very important for H5P, and in order to allow subtitles for external videos we're currently requiring that the servers they are hosted on has an Access-Control-Allow-Origin header set that allow H5P.com / H5P.org or whatever site you're using access to the video in a cross origin resource sharing manner. We see that many servers used by community members unfortunately does not have this set, and that they are not controlled by the community member either, so we're considering a solution where you can decide to allow such servers, sacrificing accessibility.(i.e. sacrificing subtitles support to use these servers).


Thanks for the quick reply BV52! I'll share this with the IT team and see if they can make the necessary changes to our servers. We have a LOT of video content and want to keep it separate from our Moodle server so it doesn't get overwhelmed whenever we import/export courses to make iterations.

BV52 I wanted to let you know our support team was able to update CORS to fix the problem. I cleared my browser cache and the video (including captions) now work as expected. Thanks again! FYI: we pass our courses through multiple servers as they move through development, so I was warned that it might be necessary to clear the browser cache after transitioning from server A to B to C.

Hi jcm3,

I'm glad it is working now and thank you for getting back to us. If you have other questions feel free to  post in the forums.

Hi all,

I've submitted a pull request on GitHub that allows administrators to disable CORS (for certain servers or all, depending on the value of crossoriginRegex):


For this to work on moodle another pull requests for the h5p-moodle-plugin must be accepted because there is a bug in there. (H5PIntegration.crossoriginRegex) is never set.


It would be great if these pull requests were reviewed by the core team!
