MP4 files not working on Chrome

Vinicius_Goncalves reported an issue with playing .mp4 files on Chrome, which works fine on Safari. pfaffman was able to download the file and play it in Chrome, suggesting it’s not a codec issue. pfaffman also encountered issues uploading the file to test on his own site.

simon tested the file on Firefox and Ubuntu, encountering the same issue as Vinicius_Goncalves on Chrome. However, simon mentioned that MP4 files uploaded to his Discourse site using Chrome work without issues on Chrome and Firefox.

pfaffman suggested that the issue might be related to files created on a Mac not working in other places. Vinicius_Goncalves plans to try uploading the files using a Windows laptop to resolve the issue.

Additionally, Vinicius_Goncalves asked if there’s a workflow to make a .mp4 video play automatically and in a loop on the forum page, similar to a GIF.

Hi there,

When I try to play any .mp4 file on forum it works fine just if I am using Safari, but it doesn’t work if I am using Google Chrome. Can someone take a look and do a test as well?

Here you have an example: Early Access to Electromagnetic Simulation - News & Announcements - SimScale CAE Forum

If you open it using Safari, it works. But if you open the video in the link with Chrome, it doesn’t work.

Any hints please?

I was able to download it and then play it in Chrome (so it’s not obviously a codec issue), but I was unable to upload it to test it on my own site. It just froze at uploading 100%.

It could be that something about that file is incompatible with the embedded player.

Hi @pfaffman,

Thanks for your help. I just uploaded that video using Safari. In this case, what should be a good approach to solve it? Delete the video and then upload it again, now using Chrome to upload that?

best,

Oddly, on Firefox on Ubuntu I’m seeing this:

On Chrome I get the same results as Jay.

MP4 files uploaded to my Discourse site using the Chrome browser work without issues on Chrome and Firefox.

Thanks for testing @simon !

What you think could be a solution to this? I ask because using Safari it is working well, so I have no idea on how to figure it out.

best,

I remember seeing a similar issue in some other context in which files created with the Mac didn’t work in other places. (And now that I see that, it sounds really sarcastic, but it’s not meant to be.)

@pfaffman ,

Thanks. I will try to upload all video files using a windows laptop and then cross my fingers. I will update here if this works.
BTW, is there any workflow to make a .mp4 video playing automatically and in a loop (e.g.: like a GIF was meant to be) on that forum page?

Appreciate your help,
