Rename to .ts and repeat... OBSERVED RESULTS $ xdg-mime query filetype x.ts text/vnd.qt.linguist EXPECTED RESULTS $ xdg-mime query filetype x.ts video/mp2t SOFTWARE/OS VERSIONS Neon Testing Plasma : 5.22.4 Frameworks : 5.85.0 Qt : 5.15.5 ADDITIONAL INFORMATION Seems to be an issue with the "magic" for the MPEG-2 TS entry, it has priority "50". The Linguist entry also has an implicit priority of 50 (the default priority) If the MPEG-2 TS priority is increased to 70 in an "override.xml" file (in /usr/share/mime/packages folder), this fixes this issue (Issue extracted from Bug 420939) 2051515 1 tagwerk19 2021-08-05 16:47:50 +0000 Also upstream: https://gitlab.freedesktop.org/xdg/shared-mime-info/-/issues/166 Impacts baloo as it depends on the mimetype to work out whether it extracts video specific metadata 2052617 2 140645 tagwerk19 2021-08-10 21:19:07 +0000 Created attachment 140645 Synthetic test for video/mp2t 2052631 3 tagwerk19 2021-08-10 21:51:24 +0000 Looks like a regression with KDE Frameworks 5.85.0 The attached test.4445.ts file is considered audio/vnd.dts.hd with Frameworks 5.84.0 and below (tested 5.84.0, 5.83.0, 5.80.0) With 5.85.0 the file is considered to be text/vnd.qt.linguist or text/vnd.trolltech.linguist (*) Carefully taking a step back though... The mimetype ought to be video/mp2t (as per Bug 440632), this is just a failure mode. 2052635 4 tagwerk19 2021-08-10 22:12:40 +0000 It seems that the shared-mime-info (freedesktop.org.xml) file included in Neon Testing is release 2.0, or at least it does not include the Make text/vnd.trolltech.linguist the canonical name for text/vnd.qt.linguist change in release 2.1 2052713 5 tagwerk19 2021-08-11 13:37:21 +0000 (In reply to tagwerk19 from comment #3) > Looks like a regression with KDE Frameworks 5.85.0 > > The attached test.4445.ts file is considered audio/vnd.dts.hd with > Frameworks 5.84.0 and below (tested 5.84.0, 5.83.0, 5.80.0) No. Scrub that :-/ Have an instance of a Frameworks 5.84.0 system giving text/vnd.qt.linguist (Neon User) and another 5.84.0 (SUSE Tumbleweed) giving audio/vnd.dts.hd I don't see a pattern, no correlation with version of Plasma, Frameworks or Qt. However an older Neon User Plasma: 5.22.0 Frameworks: 5.83.0 Qt: 5.15.3 returned audio/vnd.dts.hd. When it was updated to Plasma: 5.22.4 Frameworks: 5.84.0 Qt: 5.15.3 it returned text/vnd.qt.linguist. Sorry, cannot help more than that. 2121101 6 faure 2022-05-04 08:35:40 +0000 $ kmimetypefinder5 test.4445.ts video/mp2t $ kmimetypefinder5 -c test.4445.ts video/mp2t This is the expected result, right? What do you get? Do you have interference from bogus mimetype definitions? Find out with `grep -rwl '\*.ts' ~/.local/share/mime/packages /usr/share/mime/packages` which should only say /usr/share/mime/packages/freedesktop.org.xml 2121262 7 tagwerk19 2022-05-04 20:31:38 +0000 (In reply to David Faure from comment #6) > This is the expected result, right? I think so. > What do you get? I've just tried this with a couple of Fedora betas... With Fedora 36 beta (Gnome), I get: $ xdg-mime query filetype test.4445.m2ts video/mp2t $ xdg-mime query filetype test.4445.ts video/mp2t $ xdg-mime query filetype test.4445 video/mp2t Which looks as I think it should. However with Fedora 36 KDE beta I get the strange: $ kmimetypefinder test.4445.m2ts video/mp2t $ kmimetypefinder test.4445.ts text/vnd.qt.linguist $ kmimetypefinder test.4445 audio/vnd.dts.hd I get the same when querying with xdg-mime instead of kmimetypefinder and also when using Neon Testing. Getting different results from two spins of one distro is interesting. I'll rerun the tests when F36 is properly released In each case: $ grep -rwl '\*.ts' ~/.local/share/mime/packages /usr/share/mime/packages grep: /home/test/.local/share/mime/packages: No such file or directory /usr/share/mime/packages/freedesktop.org.xml The two spins of Fedora have the same freedesktop.org.xml (shared-mime-info-2.1-3.fc35.x86_64). I think "wierd" and it would be nice to debug messages from kmimetypefinder... 2121270 8 tagwerk19 2022-05-04 21:02:39 +0000 (In reply to David Faure from comment #6) > $ kmimetypefinder5 -c test.4445.ts Sorry I missed the '-c' option, I get "audio/vnd.dts.hd" for all three files (on Fedora 36 KDE beta) 2121343 9 tagwerk19 2022-05-05 09:17:35 +0000 (In reply to tagwerk19 from comment #7) > ... also when using Neon Testing. OK, not quite true With Fedora KDE, for test.4445.ts, I get: text/vnd.trolltech.linguist and for Neon Testing, I get: text/vnd.qt.linguist The Neon Testing still shows shared-mime-info being version 1.15.-1 2125061 10 tagwerk19 2022-05-20 17:47:48 +0000 (In reply to tagwerk19 from comment #7) > I'll rerun the tests when F36 is properly released Revisiting... F36 still seems to have the shared-mime-info-2.1.3.fc35.x86_64 package With Fedora Workstation 36 (Gnome), a new install of Fedora-Workstation-Live-x86_64-36-1.5.iso, I get: $ xdg-mime query filetype test.4445.m2ts video/mp2t $ xdg-mime query filetype test.4445.ts video/mp2t $ xdg-mime query filetype test.4445 video/mp2t Which I feel is as it should be. With Fedora 36 KDE, a new install of Fedora-KDE-Live-x86_64-36-1.5.iso, I get: $ kmimetypefinder test.4445.m2ts video/mp2t $ kmimetypefinder test.4445.ts text/vnd.trolltech.linguist $ kmimetypefinder test.4445 audio/vnd.dts.hd And with the "-c" argument: $ kmimetypefinder -c test.4445.m2ts audio/vnd.dts.hd $ kmimetypefinder -c test.4445.ts audio/vnd.dts.hd $ kmimetypefinder -c test.4445 audio/vnd.dts.hd The test file satisfies the "magic" for both video/mp2t and audio/vnd.dts.hd $ od -c test.4445.ts 0000000 \0 \0 \0 \0 G \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 0000020 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 * 0000300 \0 \0 \0 \0 G \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 0000320 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 * 0000600 \0 \0 \0 \0 G \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 0000620 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 * 0001100 \0 \0 \0 \0 G \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 0001120 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 * 0001400 \0 \0 \0 \0 G \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 0001420 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 * 0010520 \0 \0 \0 \0 \0 \0 \0 \0 \0 d X % 0010535 2239778 11 stefan.bruens 2023-07-05 17:53:45 +0000 Not a kfilemetadata bug, but SMI.
