Hi,
I am trying to use dspmpeg4sink on maemo, but it never works. I used
the following pipeline.
gst-launch-0.8 udpsrc ! video/x-h263 ! dspmpeg4sink
and this happens
RUNNING pipeline . . .
ERROR: pipeline doesn't want to play.
I had sent mails and gotten very good responses, but I wonder if any
body has any clue on why it doesn't work, atleast as normal gstreamer
plugin.
Regards,

I'm facing similar problem, trying to build by myself a pipeline with
dsp sinks:
I type on the console:
Nokia770-13:/home/user/MyDocs/.videos# gst-launch-0.8 gnomevfssrc
location=IceAge2_trailer.avi ! avidemux name=demux demux.audio_00 !
dspmp3sink demux.video_00 ! dspmpeg4sink
RUNNING pipeline ...

The sound is well decoded and outputed, but I have no video at all.
The same of course if I launch the video only pipeline.

I guess there are some tricks to configure the dsp and fb, programming
the location and size of the output on screen for example..
Could you, nokia guys, provide more information to the community on how
to use dspmpeg4sink from command line?
for example, how to produce these lines:
osso-media-server[914]: GLIB WARNING ** default - failed to init[
6159.287567] [dsp] FBCTL_ENABLE received, but fb is already enabled.
ialize dsp MPEG4 node, error = 0x0A

ProcXSPDispatch: 3

register dsp area: 0, (176, 62), 600, 360

For those who are interrested, I ve compiled gstreamer in debug mode and
produced some gst-inspect documentation on the proprietary plugins of nokia.
