.mp4 links do not embed

AI-generated summary

User danielabc reported that .mp4 links (e.g., from Imgur) do not embed on their Discourse forum, despite working elsewhere. Canapin tested the same link on a fresh Discourse install and confirmed it embeds correctly, suggesting the issue may be configuration-related. JammyDodger advised checking the authorized extensions setting to ensure .mp4 is still permitted — danielabc confirmed it is set to mp4 but the issue persists. Canapin expressed uncertainty about the cause. Later, Canapin retested on danielabc’s forum and found the embed now works, prompting a request for clarification on whether the issue is resolved and what (if anything) was changed. danielabc also briefly asked if Discourse can be installed from scratch without member accounts — unrelated to the embed issue. No definitive fix was identified, but the problem appears to have resolved itself or was corrected outside the thread.

I see that link embeds here, but not on my forum, what setting to embed .mp4 links?

Do you have a link to a post on your forum where the embed doesn’t work?

I tried on a fresh Discourse installation, with no modification, and it works straight out of the box:

You could check authorized extensions to make sure you’ve not removed it at some point?

Well, unfortunately I have no idea. :slightly_frowning_face:

is there an option to install speech from scratch without members account?

I tried again to paste an mp4 link from Imgur on your forum and it worked:

Is your issue resolved? If it is, can you share what you did to fix it?
