The site no longer accepts .mp4

[+thexfile Subscriber²]

I tried to upload a 247kb MP4, but there’s a problem with the site.

It probably doesn't help that its copyrighted material.

It's nothing copyrighted. It's just a screen grab.

I used a different screen grab software.

That actually IS copyrighted material, FYI

But remember - MP4 is just a container, the codec used will have an impact here

Define "doesn't accept", because I can play all the videos, including the mp4 in the OP, just fine...

Perhaps you're missing a codec?

I used ffmpeg to encode the first one.

Then I used FlashBack Pro to make the second one.

Those are not codecs, they're applications.  A codec is an enCOder/DECoder library; things such as DiVX, H.264 (AVC), H.265 (HEVC), H.266 (VVC), AV1 and so on and is the actual data format of the video within the video container (AVI, MKV, MP4 etc).

All of your videos play fine for me on the forum, on a variety of machines including phones and tablets.  I checked your first video and it appears to be H.265 HEVC encoded.  This is fully supported by this board software, browsers and OS's that I know of.  I suspect your issue is purely local.

On my iPhone running ios26 the only video that actually plays is the last one.  The rest are all just broken videos that don’t load.

That's a you issue, not a server issue.   I'm on Android and every one of those play fine.

So your phone doesn't support the CODECs the videos use.  There's nothing wrong with the videos.

It’s an iOS issue not a me issue.  It’s not my phone being specifically configured. It’s a me issue if no other iOS devices have the problem.  

I tried on my iPad and had the same issue. 

Should learn what a you issue is.

The question is, did they used to work.  If not then yea it was just never supported.   If the issue appeared after a forum change then something funky going on. 

All I can do as I am not OP and only tried for the first time is report what I saw.

Nope, nothing has changed there. It is 100% up to the client to have the proper codecs. The site doesn’t convert audio to different codecs; it is just hosting and giving access to the file(s).

I don’t know what the backend does compression wise or otherwise.  That’s why I wondered if something changed. 

Like having additional processing to compress or reduce framerate on upload isn’t outside the realm of possibility.

It is for a forum like this. 
 

Those are not quick tasks to be handled on the fly during upload.

Machines are powerful now.  It’s just a php site it could totally trigger ffmpeg or other to quickly post process after upload without too much overhead. 

If that’s not what happens then for sure it’s just a codec thing if how the content is served or managed wasn’t changed.

We would have to know the server specs to be certain there. Most web servers are not powerful unless they need to be.

But even with a powerful machine, you will not see no overhead from something like that converting on the fly while uploading.

We are just making assumptions.  Files can be uploaded fully and then processed.

A mod would have to be confirm to be sure, but I know of NO forum board software that does ANY kind of compression on uploaded files. They just store as uploaded and provide a link.  Your local machine and the browser you use handle all playback functions.

This is not YouTube.

It does not occur on this forum.

I’ll make a friendly wager it doesn’t.

And that would be the remit of a video delivery site, not a forum.

I uploaded a file here...some random small-sized .mp4 and the audio/video plays just fine.  Downloading the file from the forum yields the exact same properties (including encode date) as the original.  I'd wager the issue is on the OP side.

I can't play the first video on my desktop Edge or Firefox.
