Description Damir Perisa 2004-09-27 17:41:12 UTC

Version:           1.1 (using KDE 3.3.0, Arch Linux)
Compiler:          gcc version 3.4.2
OS:                Linux (i686) release 2.6.8.1-mm4

i want to be able to disable crossfading and fading-in with gst-engine

why? because:

- bug 90317 is probably related to x-fading

- while gst-engine is x-fading to next song or fading-in to a clicked one, (somehow this only happens with m4a (mpeg4audio)), it is skipped and next song is loaded, but this is also fading-in and also skipped (what is very annoying)

workaround to second reason: set fade-in of gst-engine to 0ms: then only one song is skipped (very funny, because you select one song in playlist and the next one is actually played)

Comment 1 Damir Perisa 2004-09-27 17:42:09 UTC

another workaround: press PLAY-PAUSE-PLAY (3 times press on PLAY), what makes the actual song playing (but this behaviour is very funny)

Comment 2 Damir Perisa 2004-09-27 17:44:28 UTC

here the output of such a situation of skipping and finally playing one of the songs in playlist:

Comment 3 Damir Perisa 2004-09-27 17:48:42 UTC

pressing NEXT causes this output and stop of playing:

amarok: [Gst-Engine] Destroying input pipeline.
amarok: BEGIN [InputPipeline::~InputPipeline()] 
amarok: Destroying input bin.
amarok: END [InputPipeline::~InputPipeline()]

then pressing PLAY, this happens:

amarok: [InputPipeline::InputPipeline()] 
amarok: [virtual bool GstEngine::play(uint)] 
amarok: [Gst-Engine] Fade-in finished.
amarok: [virtual void GstEngine::pause()]

but still no musik

again pressing PLAY, this comes:

amarok: [virtual void GstEngine::pause()]

and also the song "07 I ha di gärn gha" starts playing (finally)

Comment 4 Damir Perisa 2004-09-27 17:50:48 UTC

somehow play() and pause() are sometimes ignored, while fading-in or crossfading i think (not sure) so this causes negotiation problems with gstreamer core (only a guess)

Comment 5 Damir Perisa 2004-09-27 17:53:27 UTC

from time to time while this fast skipping of songs comes, this is outputed:

(process:4300): GStreamer-WARNING **: inconsistent state information, fix threading please

this is maybe the key to problems (not at all sure)

Comment 6 Damir Perisa 2004-09-27 18:00:09 UTC

FOUND A SOLUTION TO THIS WILD SKIPPING:

[configure amarok]-[playback]-[Transition Behaviour]:
set this to "Normal" and use an Insert gap of at least 1000ms

this solves the errors from gst-engine while playing/going to next song if it is m4a

nonthematter i want to be able to disable the fading-in and xfading for gst-engine

Comment 7 Damir Perisa 2004-09-28 15:29:13 UTC

comment 6 is not always working --- sometimes i need more than 3000ms to have it working (else, it plays another track instead of the one i clicked)

the behaviour was not like this in gst-engine in amarok 1.0.2 -> i think the fading causes the troubles

Comment 8 Damir Perisa 2004-09-28 15:32:24 UTC

using alsasink, it works a little better, but sometimes amarok simply crashes with this in console:

Comment 9 Mark Kretschmann 2004-09-29 19:32:57 UTC

*** Bug has been marked as fixed ***.

Comment 10 Damir Perisa 2004-10-12 14:52:21 UTC

it is solved: if i click on a song in m4a and using gst-engine, it plays immediately

thanx!

however, there is one small thing, that is still not OK: Bug 91181 : after playing the one song, the player do not advance to the next track
