Unable to view WEBP comics in lastest YACReader

In YacReader 9.15.0.2501014 for the Mac, if I try to open a CBR or CBZ with WEBP files, I get a "Comic not found" error.

This is on an M1 Pro based MacBook Pro running Sequoia 15.1.1 (24B91).

Thanks,
Bill

Check the system info in the help dialog, is webp listed there under APP INFORMATION/Image formats supported, if so, there must be other problem.

Send me the file if you can.

I am having no issues opening comics with webp images on macos with the latest version. How did you install it? Is it the official dmg file?

I do not see WEBP listed in the supported formats.

Yes, I installed via the official dmg file.

Install the qt6 version please: github.com/YACReader/yacreader/releases/...014.MacOSX-U.Qt6.dmg

I was putting together an email with more info, and a link to an example cbz file, when I noticed something in the system info:

That is listing the CPU as x86_64. I am running an M1 Pro chip, and I remembered you went with a universal build some time ago.

I ran a mac system report to get app details, and sure enough, the app kind was Intel instead of Universal or Apple Silicon.

I regrabbed the dmg file from the site, and there, the app type was indeed showing it was universal, so I reinstalled.

Now YAC Reader shows it is universal, it is still showing the same version number (9.15.0.2501014), here is the current reported System Info:

It is arm64 now, QT is 6.3.1 instead of 5.15.16, and webp is listed. Most importantly, I can open WEBP files again.

Is it possible the dmg file was replaced on the app within the last two days? If not, I somehow grabbed the intel only, QT5 build. I'm not sure how, as I always download from www.yacreader.com/downloads as opposed to the github page.

Anyway, the issue has been corrected on my machine. I'm not sure what happened, but there is a possibility this was a PEBCAK problem on my end. (PEBCAK: Problem Exists Between Chair and Keyboard)

I just posted my long reply, and saw your "qt6 version" reply immediately after.

Thank you,
Bill

I have been doing changes in the web so it could be that I messed up the download links, anyway, the Qt5 version should include webp support, I need to see where the problem is in the build pipeline.

This isn’t your Mac , it’s very likely the current YACReader build. Version 9.15 has had some issues with WEBP files inside CBZ/CBR archives on Apple Silicon Macs. That “Comic not found” error usually means it fails to read the images inside the archive. Fully quit YACReader and reopen it to see if it was just a library hiccup. You can also try removing and re-adding the comic to your library. If that doesn’t work, extract one of the CBZ/CBR files and check if the WEBP images open normally in Preview. If they do, then the problem is definitely YACReader’s WEBP handling. Right now the most reliable fix is rolling back to version 9.14, which didn’t have this issue. Otherwise, converting the WEBP images to JPG/PNG and re-zipping the comic works as a temporary workaround. it’s not anything wrong on your end — just a compatibility bug in the latest version.
