I've loaded a large playlist (18,000+ tracks) and am getting occasional pauses during shuffle playback - pauses last for two or three minutes and always seem to start at three seconds into the track. Eventually replay continues at an advanced point in the track it paused on - maybe it restarts at the point in time the track playback is at? E.g. playback pauses at :03 seconds into the track and pauses for 1:30 - then resumes at 1:33 into the track? I'm not sure about this - I'll have to document the behaviour more carefully.

Anyway, the pausing is annoying. I don't know how to determine if it's on Phonon or what. I'm on Fedora 20 with MATE if that helps.

Thanks.

OK, it just did the pause. It paused for about 1:50 to 2:00 on a track that was 1:52 long and then Amarok crashed.

As already mentioned in the other post: you should not load such huge playlists, using a dynamic playlist would be much better...

Did you try changing the Phonon backend? Depending on the version you use you should check you really have the newest gstreamer backend with only the 1.x gstreamer plugins, because mixing plugins from different versions can cause quite some problems.

So what is the maximum size of playlist to load? I meant to ask that and forgot.

Phonon version is 4.7.2-1.fc20.1 and phonon-backend-gstreamer is ver. 4.7.2-1.fc20.1.

There is de facto no maximum playlist size, but each entry in the playlist has to be checked when the playlist is loaded, the more entries there are, the longer it takes. Ditto for dynamic sorting in a playlist: the more tracks, the longer it takes.

It would really be the best to add those tracks to the collection in Amarok and then use the Dynamic Playlist mode to load never played tracks. That playlist automatically updates and ends once all tracks are played. The big advantage is that it only loads a limited set of track at once and updates automatically.

As for the Phonon backend: your version supports the gstreamer library 0.10 only IIRC, so please make sure you have plugins for the gstreamer 0.10 version , if you use plugins from the 1.x series that will cause problems.

I would really encourage you to upgrade your installation to get a newer Phonon backend, starting with the version 4.8 beta (current release is 4.8.2 IIRC) the gstreamer plugins version 1.x are fully supported.

For Fedora 20 I'm already at the latest version. I don't understand Linux enough to compile and install v.4.8.3 - but there is an rpm available. However, the Photon page says, "Make sure that Qt-4.8.6 is compiled without the bundled Phonon library. This package provides a better implementation."

I already have qt 4.8.6-25.fc20. If I remove qt, will yum get the better implementation of it automatically when I install the rpm?


Thanks.

Don't remove Qt, please don't you would ruin everything

Upgrading your Fedora to Fedora 21 should suffice.

Upgrading was interesting.

Thanks very much for all your help.

I'm trying-out KDE-Fedora25 and note it isn't quite the same as Mageia (in terms of desktop response), and therefore I am running into choppy music too.
I tried looking for info and found this thread with similar problems.
I'm running an older computer (by today's standards), so it seems a bit sluggish.
This is a fairly fresh install, so the playlist is basically the Amarok intro music, and 1 CDrom, total of about less than 10 songs)

What I tried and is working okay now is to start a Konsole terminal, and use the nice command.

Code: Select all

nice -10 amarok

What it does is schedule Amarok to be more important in the list of programs to run.
This isn't an ideal solution, but it is a quick solution until a better fix is made.
Amarok is still running smoothly even though I have BOINC running 100% under a similar konsole as:

Code: Select all

nice boincmgr
