GStreamer pipeline error


I'm not able to play anything using gstreamer. I've followed Felipe's
guides on DSP and gst-openmax but when I try to play a file I get the
following error:

Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...

****************LCML ERROR : DSP ************************
Error: DSP Manager Open : Err Num = 80008008
****************LCML ERROR : DSP ************************
ERROR: from element /pipeline0/omxmpeg4dec0: GStreamer encountered a
general stream error.
Additional debug info:
gstomx_base_filter.c(716): pad_chain (): /pipeline0/omxmpeg4dec0:
Error from OpenMAX component
ERROR: pipeline doesn't want to preroll.
Setting pipeline to NULL ...
328 :: Error From ComponentDeInit..
FREEING pipeline ...

I've loaded the bridgedriver module and registered all files in /lib/
dsp using dynreg.out.

Any suggestions?

Many thanks in advance
