Bug 362975 – media-sound/amarok with media-libs/phonon-vlc-0.4.0 backend fails to play some mp3 files

• Status: RESOLVED WORKSFORME
• Product: Gentoo Linux

[Description MarisN 2011-04-10 21:30:14 UTC]

Recenlty phonon default backend seems to be changed to VLC from xine. After this change some MP3 files are not player anymore by any phonon using application (amarok) without any error message. Xine backend and standalone xine, mplayer, mpg123 play that file just fine.

Will attach VLC -vvv output on one of unplayable files.

Reproducible: Always

How about other backends? xine/gstreamer, do they play the file?

Sorry for my bad language skills.
I don't have phonon-gstreamer backend only xine one. After changing phonon to xine backend, Amarok plays all files just fine.
So - there are two problems - VLC backend fails to play some MP3's and second - there are no meaningfull error messages for user - Amarok just skips files as unplayable. At first I was surprised that Amarok suddenly started to skip some files from my collection as some time a go it was playing them just fine. Not nicest way how to find out about a new phonon backend :(

Welcome to the brave new world full of features.

So our culprit indeed is the vlc package. Could you check if it has mp3 useflag enabled?

PS: your English is quite good :)

Apparently not good enough, as I wrote - "some MP3 files ... fail".

mp3 useflag on vlc just means use libmad instead of ffmpeg implementation for playing mp3 files. So my question was more to find out if you use libmad of ffmpeg :) (yes vlc can always play mp3 files technically)

Try to disable the mp3 useflag and see if the problem is still around :)

In any case, this is an upstream bug so all we can do is track this through an upstream bug.

After emerge vlc with -mp3, it still fails.

Still I managed to track down cause of error - those MP3 have different tags.

EasyTag, Amarok, mplayer, xine, mpg123, id3info all display one tag content and are able to play file (ofcourse EasyTag and id3info doesn't play anything at all ;)

mplayer doesn't display album_artist tag at all. mplayer plays just fine with -ac mad, ffmp3, ffmp3float, ffmp2

Amarok displays album_artist to be "Röyksopp"

ffplay is able to play file but it displays different content for album_artist tag - "刀礀欀猀漀瀀"

After stripping all ID3 tags from file with "id3convert -s", VLC starts to play it. Bad thing - stripping "Album artist" tag contents in Amarok do not affect contents displayed by ffplay and VLC still doesn't play such file.

Conclusion: bug lies somewhere in VLC ID3 tag processing part.

Can you please test phonon-vlc-0.4.0 that I just added to the tree?
Let us know if the issue persists or if it's fixed.

Still an issue with:
media-libs/phonon-vlc-0.4.0:0
media-video/vlc-1.1.10:0

[Comment 11 Andreas K. Hüttel 2011-11-08 19:53:00 UTC]

It's probably best if you file an upstream bug on bugs.kde.org and link to it here. That said, upstream is not always that responsive...

[Comment 12 MarisN 2011-11-12 14:00:21 UTC]

Tested with media-video/vlc-1.1.12 and could not reproduce anymore. Either I have fixed mp3's tags or it has been fixed upstream.
