Package: rhythmbox
Version: 0.8.8-13
Severity: minor

README.Debian contains a wrong gst-launch pipeline in the 'Before
reporting a bug' section:

 gst-launch-0.8 gnomevfssrc location=/path/to/my/musicfile.ogg ! \
   spider ! volume ! audioscale ! audioconvert ! $(gconftool-2 \
   -g /system/gstreamer/0.8/default/audiosink)

This will fail whenever the file in question is an ogg/vorbis audio
file, ie. almost always. The reason is that the vorbis decoder produces
audio buffers in audio/x-raw-float format [*], but audioscale can only
handle audio buffers in audio/x-raw-int format. This results in a
negotiation error (gst_pad_try_set_caps fails etc.).

This negotiation error is the result of an erroneous pipeline and not a
GStreamer bug.

The pipeline should be:

 gst-launch-0.8 gnomevfssrc location=/path/to/my/musifile.ogg ! \
  spider ! audioconvert ! audioscale ! $(gconftool-2 \
  -g /system/gstreamer/0.8/default/audiosink)

(ie. audioscale and audioconvert should be swapped in order, and 
 there should be no level element, to keep it simple).

 Cheers

[*] I think at the very beginning of the 0.7/0.8 series, the vorbis
decoder produced audio/int, but that was changed to float at some point,
so the pipeline did work for that at some point even though it is not
entirely correct :)
