Description lazx888 2011-04-03 15:13:36 UTC

Version:           2.4-GIT (using KDE 4.6.1) 
OS:                Linux

When playing an MP3 with CUE file, the CUE is parsed properly, but playback/transition to next track is broken.  Amarok plays the first track okay, but does not play next track.

Reproducible: Always

Steps to Reproduce:
1) Use VLC-phonon or GStreamer-phonon backend.
2) Load mp3 that has a cue file.
3) Play track and wait for transition to next track

Actual Results:  
1) Playback stops (no transition).
2) Unable to restart playback of mp3 with cue file.  Loading a different mp3 and then retrying playback of mp3 with cue file allows ONE track of mp3 with cue file to be played again, but upon transition to next track playback is broken again.

Expected Results:  
Gapless transition to next track of mp3 with cue file.

Comment 2 domponforums 2011-04-03 15:43:21 UTC

yeah, this isn't working and is a show stopper for any cd that has a .cue file in the same directory. Please offer an option to disable .cue file support in amarok or fix the bug.

thanks!

Comment 3 lazx888 2011-05-23 19:10:59 UTC

Update:

I have tried git amarok (20110523), git phonon-mplayer (20110523), and git phonon-xine (20110523) - still no luck.

Is this an amarok and backend issue?

Is there any other info I can provide to help out with this bug/lack of feature?

the mplayer and xine backends are deprecated, please use the gstreamer or vlc ones instead.

Most likely an Amarok one, as the CUE support still is not fully implemented.

Not really, we need more developer time and availability.

Comment 5 Sven Krohlas 2011-06-19 15:49:31 UTC

Confirmed in git master. Is this a regression?

Comment 6 Myriam Schweingruber 2011-06-19 18:02:03 UTC

No, not a regression, just never implemented.

Comment 7 Basti 2011-07-10 07:40:28 UTC

I can confirm this bug. I played a mp3 file using an .cue file. After the first song was played Amarok plays the first song again. No matter which song I want to start, Amarok always plays the first! So there’s no way to listen to the hole mp3. Using Amarok 2.4.1, phonon-gstreamer-4.5.0.

Comment 8 Andreas Kirsch 2011-10-20 14:24:45 UTC

I have the same problem with Amarok 2.4.3 under KDE 4.7.2 and phonon-gstreamer-4.5.1. The only workaround is to move the cue-file to another directory.

Comment 9 Myriam Schweingruber 2013-04-11 08:58:05 UTC

What is the status of this with Amarok 2.7?

Comment 10 Myriam Schweingruber 2013-07-12 15:07:44 UTC

Bump version.
