Senhores

Tentei usar o gstreamer no Ubuntu 9.04.

Porém, quando dou o comando: gst-inspect, não aparece nenhum elemento, filtro ou plugin:

serkam@serkam-desktop:~$ gst-inspect
coreelements:  multiqueue: MultiQueue
coreelements:  typefind: TypeFind
coreelements:  tee: Tee pipe fitting
coreelements:  filesink: File Sink
coreelements:  queue: Queue
coreelements:  identity: Identity
coreelements:  filesrc: File Source
coreelements:  fdsink: Filedescriptor Sink
coreelements:  fdsrc: Filedescriptor Source
coreelements:  fakesink: Fake Sink
coreelements:  fakesrc: Fake Source
coreelements:  capsfilter: CapsFilter
coreindexers:  fileindex: A index that stores entries in file
coreindexers:  memindex: A index that stores entries in memory
staticelements:  bin: Generic bin
staticelements:  pipeline: Pipeline object

Total count: 3 plugins, 16 features

Os pacotes base, good e ugly estão instalados.

Preciso fazer alguma inicialização antes?
