EDIT: seems to be mainly an instance issue instead of an app issue. Viewing the linked comment on another instance will play the gif properly

I've only noticed this in comments so far. Certain WEBP videos show me a play button, but will never play when I tap on them. I'm assuming this is probably an app issue, but could maybe still be an instance issue.

Here is one comment that has this issue:

I'm on the latest version of summit on an S23 Ultra.

That's interesting, for me it works with with Summit on GrapheneOS. I also see this huge play button like you, but when I tap it, a video player opens in full screen and plays the video.

Edit: but for me the play button is crisp and not pixelated:

Hmmm. Sadly, I have no idea if maybe it's caused by some sort of instance/proxy issue.

Well, they aren’t supported by Lemmy. I can’t upload WebP via browser; it’s not an allowed file type, apparently.

But just as a test, an embed:

The above image works for me. There’s no play button, it just auto plays.

iPhone, iOS, Orion Browser (which is basically Safari)

Doesn't even appear for me :/

I can't upload regular .gifs, either. It just shows the first frame as a static image. Have to upload them to something that actually supports them properly and then embed that link for the animations to work.

It could be supported, but the instance operators would need to add it to their setup. IIRC, Tesseract (the instance) has done that. At least I think that was one; this is a really old issue and I haven't seen it discussed in over a year (back when I was still on Yiffit).

If you visit Lemmy on your mobile browser, does it work?

Here's the URL for convenience: https://lemmy.world/post/49346609/24736019

It works through that link but does not work when viewing the comment through my own instance:

So I guess it is an instance issue after all...

Just tried the original comment I linked to in the body of my post. Viewing that post from the original instance, even while in the app, it works. As soon as I view the post on my instance, it just displays the pixelated play icon.

Ohhh, I see what's happening @Bubs@lemmy.zip

This is the URL I actually get for the image on Lemmy.zip:

https://images.lemmy.zip/api/v3/image_proxy?url=https%3A%2F%2Fconvertico.com%2Fsamples%2Fwebp%2Fanimated-webp-3.webp

It appears to be trying to automatically convert the image with convertico.com, which fails because it's an animated webP, I guess?

The error I get returned is:

code	"validate-width"
msg	"Too wide"

...This seems like a very janky default.

Why does Lemmy.zip try to convert webps with convertico?

Its not, the webp you embedded is from convertico.

Other instances may not use the image proxy and may be more permissive with the content they allow to be uploaded, for better or worse.

@Bubs@lemmy.zip ill take a look ASAP and see if I can figure out why the proxy is rejecting them

Yeah IDK what I was thinking.

Should work now, feel free to drop me a message if you notice anything else not working :)

Test comment:

Seems to be mostly working now. The watery room now shows up for me so that's good. The original WEBP with the play button still behaves the same though. Understandable if it's something that requires individually fixing each and every video.

EDIT: Found a recent comment with the same issue of the pixelated play button:
