[Rhythmbox-devel] usage problems with artdisplay plugin and Crossfading Support

Hi there,

before i wanted to consider this a bug, i would like to be sure that it's
not a problem between my ears :-)

Well, i installed the latest (0.9.6) version of rhythmbox on my FreeBSD
6.1-RELEASE-p10 laptop, and all is running fine, except for some plugins.

I tried to activate the cover display plugin, but i'm getting this error
when running 'rhythmbox --debug':

(16:40:27) [0x8134c80] [rb_python_module_init] rb-python-module.c:322:
Init of python module
ImportError: No module named artdisplay

(rhythmbox:106): Rhythmbox-WARNING **: Could not load plugin artdisplay

(16:40:27) [0x8134c80] [rb_python_module_finalize]
rb-python-module.c:329: Finalizing python module

(rhythmbox:106): Rhythmbox-WARNING **: Error, impossible to activate
plugin 'Cover-Anzeige'
(16:40:27) [0x8134c80] [plugin_manager_set_active]
rb-plugin-manager.c:263: Could not activate

Does anyone have a hint on why this is not working? The installation seemed
to run correctly, and i find the subdirectory artdisplay within the
plugins directory, and it's world readable of course.

Besides that,  i found the following about crossfading support in
rhythmbox - is there any news about that?

I looked into this a bit a few weeks ago. Basically:

* We'd need to write a new crossfader element. It has two input pads, one
output pad. Rhythmbox sets up and maintains TWO pipelines at once, feeding
into the crossfader. IE the crossfader element would be compulsory, not
optional without major hackage inside RB - that doesn't mean you have to
have the effect enabled though.

* The crossfader element would pull N seconds of audio into itself and
then have two internal volume elements and an adder element. You could use
the sine function to splice between them, which is easy enough, the hard
bit is pulling the right amount of audio I think. GStreamer 0.7 supports
querying a buffer for its duration.

* We could also use this element to implement gapless playback as it'd
buffer a small amount on the alternate pipeline before doing the switch.
Once the switch between the pads has occurred, the element could emit a
signal that RB would attach to and rejig the pipelines.

* Maybe a weekend or twos work. Unfortunately I am already committed to
too much stuff elsewhere in linuxland, so I can't do this....

thanks -mike

Two of the most famous products of Berkeley are LSD and Unix.
I don't think that this is a coincidence.
