Tags lost when transcoding

Tue May 21, 2013 6:52 pm
I'm using Amarok 2.6.0 on Debian Jessie. When I try to copy and transcode files (from ogg to mp3) from my local collection to my "universal mass storage collection" (ie. my phone) I lost all the tags that were in those files. All the files are showing up as "Unknown artist / Unkown track" on my phone. (Or on any other player). The transcoding was working just fine with Clementine or Amarok 1.4.

Am I doing something horribly wrong or is this a known "feature"?

You should upgrade to Amarok 2.7, there were some transcoding issues fixed in that version. Ideally 2.7.1, as there was a bugfix release for the QtWebkit <-> Gstreamer issue.


Running Kubuntu 22.10 with Plasma 5.26.3, Frameworks 5.100.0, Qt 5.15.6, kernel 5.19.0-23 on Ryzen 5 4600H, AMD Renoir, X11
FWIW: it's always useful to state the exact Plasma version (+ distribution) when asking questions, makes it easier to help ...

Ah, ok. Unfortunately upgrading is not possible for me at the moment since the 2.7 version is in the Debian experimental repository and building from the source is not really an option. So no transcoding for me then I guess.

But thanks for the info!

why not 2.7 from the experimental repo, 2.7 is not "experimental" nor beta but current (ok .1 < current)


OpenSuse Leap 42.1 x64, Plasma 5.x

Well, I haven't checked, but I would assume that Amarok in Debian Experimental has myriad of dependencies that I should also install from experimental.

Our latest stable release is 2.7.1, it is a bugfix release and highly recommended. If you wait till Debian gets something in stable you will have to live with outdated software, sorry. Rock stable no, as our 2.7.x is much more stable than the 2.6 version, just tested over much longer time. Longer testing periods doesn't make software more stable, though...

yes, you will need newer KDE package, but again, just because those are newer doesn't mean there are less stable.

Ok, I finally updated my Amarok to version 2.8.0 (I'm still using Debian Jessie).

This same bug still exists >:(

Not a single ID3 tag is being written in those transcoded files. The directory structure (<memory card root>/%artist/%album/) is created correctly though - so at least the ogg tags are correctly recognized while trancoding.

Hmm. Amarok currently depends on ffmpeg (or libav through wrapper) preserving the tags when transcoding, and it mostly works for us. Please post relevant output of `amarok --debug` (just the lines that are printed after you trigger the transfer up the the point it finishes) of a run when you transcode just one song. The ffmpeg output is included, so that should shed some light.

I'd like to change that behaviour so that Amarok would explicitly re-write the tags to transcoded tracks, hopefully I'll manage to do it on time for Amarok 2.9.
