Vertical photos are rotated

[atasinti]

Describe the bug
When I upload a vertically long photo, it gets rotated.

Hello @atasinti I cannot reproduce it. Could you tell me from which client you are uploading it?

[atasinti]

I used a client called Nostter ( https://nostter.app/ ) to upload images.
I heard from Nostter developer @SnowCait that the issue was reproduced by uploading directly without using Nostter.
Does this occur when the photo data includes rotation?

FYI

I think exif orientation information is ignored when converting jpg to webp, but I'm not sure. (ffmpeg issue?)

Hi, I have been testing. Uploading the image from nostter and from coracle. It always comes out vertically.

Can you give me more information? I'm sorry but I can't replicate it. @atasinti @SnowCait

To test, edit the image a bit so that the hash is not the same. Otherwise the server will always return the same image.

My reproduction steps (Windows 10 + Chrome)

1. Go to https://zpl.fi/exif-orientation-in-different-formats/
2. Download right image of JPEG
3. Upload the image to nostrcheck.me through "Upload file" button in my page
4. See it and it is like this

Original image in step 2. is:

My browser doesn't support orientation of WebP.

I think it is already solved 🥳🥳🥳

It was the version of ffmpeg in debian in production. I have always been testing it on my development machine which had a higher version of ffmpeg 😅

Can you validate it? Thank you very much for notifying me of the error 🙏

Orientation is solved! 🎉🎉🎉

However, aspect ratio seems to be strange.
I tested it using: (original)

ffprobe is detecting the dimensions (only of this file) backwards!!!

I'm going to have a coffee and check it out, right now I don't know if it's me or if it's really happening 😂😂

[quentintaranpino]

I just uploaded it to this site, and it also detects the width and height in reverse.

Weird... I check it!

Original image is broken...? I'm sorry.

I test another image and it works well.

Maybe, but how strange! 🤔🤔 I'm going to check it out anyway. If it's ok with both of you, I'll close this issue!! @atasinti @SnowCait 🥳🥳🥳🥳
