Is it possible that openSUSE currently has some problems with mp4-tags (tried out 12.2, Tumbleweed as well as newer taglib-1.8 versions from some build service repo)? I’m running KDE 4.9 from the OBS, both with gstreamer and vlc phonon backend.
In Dolphin, m4a files are not displayed with detailed tag info, while mp3 files are still correctly displayed with all included meta infos.
Amarok picks up and plays m4a files, however, the tags are mixed up. Trying to edit them works for one session, when the collection is read in again the tags are wrong again (some work, some mixed up, some empty).
VLC often displays the encoder info (handbrake-rev123) as file information. This is similar to to Amarok problem, where very often at first the encoder info is filling up many mp4-Tags.
In fact, it was VLC where I noticed this problem first, however I disregarded it as tags are not so important for my videos. However, in music files it is pretty annoying. As I did all my tagging with Amarok only a few months ago, and all these songs are correctly displayed on my media devices, the tagging must have worked some time ago. But as soon as I edit tags nowadays, everything is mixed up.
Can there be a guide perhaps made in the Wiki on how to work around this? I may not pay for my OS because I like linux, However I do purchase my music from Itunes, and not being able to see what the song title is… well obnoxious. I tried downloading the libtag1 file from some package site and using zypper install --force, however it didnt do anything. I guess worse case scenario I could downstep my OS to 12.1? however that seems rather drastic for something that should be quite easy to fix no?
Before that can happen, a workaround needs to be identified. When I googled the problem last year re Amarok, it wasn’t just affecting openSUSE, but others were trying to establish the source of the problem. IIRC taglib was discounted and focus was on backend systems such as gstreamer plugins, and even on Amarok itself (then). Some up to date googling is required, but feel free …

Yes, it is a PITA! Aren’t we talking about a restricted format in this case? If so then it’s hardly an issue for openSUSE devs, and the problem has to be solved upstream or elsewhere anyway. It can take time for these type of solutions to arrive downstream. It’s more likely to arrive via Packman.
