[email protected] changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] Version First|22.04.3 |26.08.0 Reported In| | --- Comment #10 from [email protected] --- I can reproduce this with Elisa 26.08.0 on Fedora 44, KDE Frameworks 6.29.0 and Qt 6.11.1. The affected files contain only an AAC-LC audio stream, but use the generic MP4 brand: major_brand=mp42 compatible_brands=isommp42 KFileMetaData::MimeUtils::strictMimeType() identifies them as video/mp4. Elisa's FileScanner::shouldScanFile() only accepts MIME types starting with "audio/", so the files are rejected with: AbstractFileListing::scanOneFile invalid mime type VLC and ffmpeg can play/decode the files normally. Losslessly remuxing them fixes the problem: ffmpeg -i input.m4a -map 0 -c copy -brand M4A output.m4a After remuxing, the MIME type is audio/x-m4a and Elisa imports and plays the files correctly. The sample attached to this bug appears to have the same cause: it contains AAC audio only, but has major_brand=isom and is detected as video/mp4. -- You are receiving this mail because: You are watching all bug changes.
