Patch for FFMPEG 7.0 compatibility: https://github.com/eclipseo/cantata/commit/0887cf117dd791192531dca47f4ec056a02b7c8a

FYI, I'm getting the same ffmpeg related error when trying to rebuild cantata-git:

I guess I'll just move to either cantata-qt6 or cantata-qt6-git

@FabioLolix thanks for maintaining these packages!

Likely I'll switch to the Qt6 fork at this point

I'm getting errors while compiling. Seems to be related to ffmpeg.

cantata - exit status 4

The latest plasma6 update is now throwing this error via journalctl: kde.dataengine.mpris: mpris:trackid from "Cantata" does not conform to the MPRIS2 standard. Please report the issue to the developer.

I don't know where to report the issue as there are several forks out there at this point, so there ya go.

Thank you for adding fenuks patch.

Thanks to fenuks

Please have md4c added to the makedepends clause. Build will fail otherwise.

md4c is a depends of qt5-base so is already in the dependency chain, if you have an error log please use a pastebin service or send it to me by email

@FabioLolix

Thank you for adding fenuks patch. The package compiles fine now indeed.

Please have

md4c

added to the makedepends clause. Build will fail otherwise.

Thanks!

fenuks's applied, the program build and works again
