AVIF decoding fails on Windows app #1624
Comments
would need:
Komga does not need to decode images when reading with the webreader, the AVIF file is passed as-is if your browser supports it, that's why you can see it when reading. Komga decodes when generating the thumbnail, the fact that it fails to generate a thumbnail seem to indicate something does not work on your machine, but logs would be needed to confirm. |
/> would need:
where can found the startup log?
it;s looks show heif.HeifException: Unsupported feature: Unsupported codec. |
It's just the first lines of the log file, but sometimes when log file rolls, it's missing in the file. The library is loaded properly:
The issue is in the decoding, could be something wrong with the file or codec. I'll check it out. |
The library works with your test image, so there must be an issue with libheif dll not loading the AOM codec. I don't have a windows machine to troubleshoot though, so there's not much i can do. |
Q1. A1. It's only failed show preivew cover with windows store version. Q2, |
shouldn't be any difference |
i've managed to reproduce the issue in a Windows CI environment, the dlls shipped with the windows app can't handle AVIF. I am trying to build new ones that will work. |
