[lionick]

I saw that in console

Can we fix that? @vgoya

About firefox:

HTTP “Content-Type” of “video/3gpp” is not supported. Load of media resource https://eduoer.up2university.eu/trackfile/5c5ac546e11a28045d8b4aa3.mp4 failed.

To sum up, this format is not supported by firefox (video/3gpp). Also, the ARIADNE endpoint says the format is video/mp4.

Normally we hide unsupported formats (like .flv videos) but in this case we can't because we are trusting the ARIADNE info.

Could ARIADNE figure out the real mimetype? That way those videos would be hidden in the platform.

Also, they can't be played on the eduOER android app either.

Hello @Alfro, I removed PLYMOUTH_UNIVERSITY from ARIADNE as all videos have video/3gpp format. Thanks. So you can remove it from eduOER also.

[lionick]

When you remove PLYMOUTH_UNIVERSITY, please remove also NSF repository as its videos seem to be broken links.

[Alfro]

Hi @lionick both repositories should now be removed.

Thank you Alfonso!
