I don't know if this is better to post here or on /g/, but does anyone know why I'm unable to post mp4's? Trying to upload any mp4 file that I have results in an error that says it's an unsupported file type, even for mp4 files that I saved from threads and attempt to post again. The files themselves are perfectly fine and aren't corrupted in any way. This has been giving me a headache

Audio on non-audio boards?

I checked. It doesn't work even if the mp4 has no audio whatsoever. Even on boards that do allow audio like /gif/, I still get the same unsupported file type error.

Have you got Mediainfo (from Windows app store or Linux package, or mediaarea.net)? ffprobe?
Using Firefox?
Try this testcard mp4.
If still problems, download the mp4 with yt-dlp (i.e. not a browser) and retry.

This site does not handle all valid webm and mp4 formats, so not surprising, for example 10 bit pixel formats are rejected.

I do have Mediainfo but I don't remember where I got it from, it's been years. I also have ffprobe as part of yt-dlp. I'm using Firefox and 4chan X. Neither of the testcard mp4s work, I still get the same error. I'm unsure how to download it through yt-dlp as putting either the video url or the thread url both result in the "You must provide at least one URL" error. I also tried to ignore the upload error when trying to post to a thread and trying to post it anyway to see if it was just a false error or bug, but it refused to send the post through. I also noticed that when I put in an mp4 file, the file extension goes away (in the pic), but attempting to manually add .mp4 back to it doesn't fix anything.

That's strange. You would think that I'd still be able to re-upload ones that were previously posted on here at the very least. Is it possible that some sort of conversion is happening when I save the files that makes them unable to be posted again?

Allowing .mp4 files is relatively new, are you sure you have the latest version of 4chanx?

>4chan X
That might be the problem as otheranon posted. I switched to 4chan-xt some time ago, on TuxedoTako's github.
I guesss to confirm, try a new Firefox profile (or container), install the usual uBlock Origin then try uploading an mp4 "naked" i.e. with no 4chan extensions at all. Time consuming, but if that works, then your 4chanX is likely the cause.
Alternatively, just do what otheranon says, uninstall the old 4chanX and use the XT fork.

>how to download it through yt-dlp
First, ensure you're up to date with "yt-dlp -U", then:
yt-dlp https://i.4cdn.org/wsr/1763365798029573.mp4
picrel is thetestsine webm downloaded thaty way (the checksum will be different because this site changes the metadata):
1763365798029573 [1763365798029573] mp4.mp4 MD5 is 95fdd42db79bb96eb7ec5ea673d49f7d

Yeah, I meant to quote my 1548989 and 154899, not your post, OP.
But, I now think it must be your 4chanX, prompted by >>1549024 - the changelog for it shows mp4 was added in v1.14.22.5:
>v1.14.22.5 (2024-11-20) - [Userscript] [Chrome extension]
> (4chenz) Support posting MP4 files on 4chan.
So, check your version is that or higher. If not, that's the cause.
But looking at the slow updates at 4chanX github (last was almost a whole year ago), I'd advise dumping it and using the XT fork, see https://github.com/TuxedoTako/4chan-xt/blob/project-XT/CHANGELOG.md
>>1549012
>Is it possible that some sort of conversion is happening when I save the files
That was my first suspicion, (who knows what some browsers get up to) but it pretty much looks like your (presumably out of date) userscript doesn't handle mp4.

All right, I made the switch to XT and it seems to work now. Thanks, anon. I guess the other one was really outdated as you said.
