Fixed Problem with webm files

[Roninlewis]

I don't know if this is a bug or something I'm not doing right. When I attach webm files, the videos won't play. The URL of the attached file has the extension mp4 instead of the extension webm and gives a format error.

From the admin panel the videos work correctly. The urls look different, in the admin panel the link points to the id of the attached file and in the forum the link points directly to the file with mp4 extension.

I confirm that in version 2.1.10 it works. Videos and their links are displayed correctly. It may be a bug from version 2.2.

I attach an example video.

Is that supposed to be a working or non working video?

This site is running 2.2 and it plays fine.

It should be able to reproduce, but it can't. At least it doesn't work for me. The link is also not correct, it points directly to the file and treats it as if it were an mp4 file instead of a webm.

This is the link of the attachment that I see.

At least it doesn't work for me.

Are you saying the attachment on this thread doesn't work for you?

What OS, browser, and device?

 

[Roninlewis]

I use windows 10 and firefox 80.0.1

Version 2.1.10 works fine.

Version 2.2 is the one that doesn't work. Videos in webm format won't play in my browser. However, if it works if I open it from the admin panel.

 

[Paul B]

Sounds like a browser specific issue.

Windows 10/Chrome and Android works fine for me.

 

[Roninlewis]

I think it is not just the browser. Regardless of the browser, xenforo 2.2 does not display the link correctly.

The correct link should have this format

https://xenforo.com/community/attachments/{filename}.{id}/

With this format the video plays correctly.

Not working in iPhone

The link in 2.2 is correct. Direct video access is important for some browsers (most notably Safari/iOS) so we serve videos directly. This is part of a change/improvement in 2.2.

However, it looks like Firefox is more particular when it comes to the MIME type of these files. Moving to bugs.

Worth mentioning that WebM isn't entirely safe for web videos because Safari/iOS doesn't support them.

 

[Roninlewis]

I think the problem is simply that xenforo puts the mp4 extension to all video formats. This also happens in version 2.1.10 but is corrected when viewing.

About the use of direct links in 2.2. Doesn't that compromise the privacy of the forum? Anyone can access the content without being registered and also the views are not counted.

Yes the problem is that the file extension is being changed to .mp4. I also can't play the above attachment on Firefox "No video with supported format and MIME type found." error. If I download the video and change the extension to .webm it plays fine on Firefox.

 

[XF Bug Bot]

Thank you for reporting this issue, it has now been resolved. We are aiming to include any changes that have been made in a future XF release (2.2.0 RC1).

Change log:

Maintain the original video/audio extension when serving these file types as directly accessible attachments as not all browsers allow sniffing between their multiple supported video (or audio) types

There may be a delay before changes are rolled out to the XenForo Community.
