Affected app version

1.1.1

Affected Android/Custom ROM version

android 10

Affected device model

Motorola moto g7 plus (nearly stock android)

How did you install the app?

None

Steps to reproduce the bug

Hi, I noticed some previews aren't rendering for all types of media (videos, gifs, movie). Clearing cache made no difference. These media can still be viewed properly by tapping and opening single view mode. I have attached one of the images for which the app fails to show a preview in folder view.

Hope this helps.

Expected behavior

Thumbnails render while scrolling the gallery

Actual behavior

Thumbnails never shows up

1. Fill the template properly, especially fields about the device.
2. 6.28.1 is not the latest version of the app.
3. File link doesn't work.

@Aga-C updated It was a copy paste text from the old repo where users got sold out. New file, yes the bug is still present in current public release

[Aga-C]

Please fill Affected device model because it is relevant. I've just tested on two different devices (image downloaded from ZIP) and have no problem, thumbnail is generated and displayed correctly.

[Meteor0id]

@Aga-C updated, moto g7. Can't see an obvious reason why my device is affected anything I could check?

[Aga-C]

@naveensingh Do you have any idea what more information we may need?

[Meteor0id]

Settings

Color sceme looks like old app but was imported

Only the preview wont load, if I tap on it the full screen inage does show

its jpg, not crazy big (10MB), resolution is little bit bigger, but still in the norm 2k/4k

@naveensingh Do you have any idea what more information we may need?

Maybe. @Meteor0id are you familiar with Android Studio or adb logcat? Can you get some logs for us? Glide often dumps useful info into the logs.

I have one Motorola phone with similar specs, I'll try to reproduce this. I think I might have seen this bug before on an emulator.

[Aga-C]

@Meteor0id Do thumbnails work correctly when you turn off Animate GIFs at thumbnails?

I was gonna create a separate issue but this one might suffice.

[Meteor0id]

@Aga-C yes turning that off kakes them appear. You are onto something

[Aga-C]

It seems to be only related to this setting, not to the device as I previously thought. Also, thumbnails for AVIF files doesn't work with this option turned on.

In code, I see that problem is with the line options.dontAnimate() in Context.loadImageBase. For some reason, it breaks both AVIF files and this JPEG.

[naveensingh]

I can also reproduce this now. Both with AVIF and the JPG provided above. I'll investigate this later today.

Thanks, Agni!

[Aga-C]

I've found out what's wrong with JPEG posted here. In fact, the file doesn't contain JPEG data but PNG data. For some reason, dontAnimate doesn't handle the case of wrong file extension.

[naveensingh]

Hmmm.

Should be fixed in https://github.com/FossifyOrg/Gallery/releases/tag/1.1.3
