Description Michael Schwendt 2011-06-21 12:57:56 UTC

The "Voice, lossless" GNOME Audio Profile specifies the following GStreamer Pipeline parameters: audio/x-raw-int,rate=22050,channels=1

However, the rate=22050 causes this:

$ gst-launch filesrc location=test.ogg ! decodebin ! audioconvert ! audio/x-raw-int,rate=22050,channels=1 ! wavenc ! filesink location=test.wav
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
ERROR: from element /GstPipeline:pipeline0/GstDecodeBin:decodebin0/GstOggDemux:oggdemux0: Internal data stream error.
Additional debug info:
gstoggdemux.c(3474): gst_ogg_demux_loop (): /GstPipeline:pipeline0/GstDecodeBin:decodebin0/GstOggDemux:oggdemux0:
stream stopped, reason not-negotiated
ERROR: pipeline doesn't want to preroll.
Setting pipeline to NULL ...

Whereas the default (or rate=44100) works:

$ gst-launch filesrc location=test.ogg ! decodebin ! audioconvert ! audio/x-raw-int,rate=44100,channels=1 ! wavenc ! filesink location=test.wav
Setting pipeline to PAUSED ...

The channels= and width= parameters work. The rate= parameter only takes 44100 Hz. Values like 22050, 11025, 8000, 48000 all fail.

Comment 1 Michael Schwendt 2011-06-21 15:51:03 UTC

Seems to be a limitation of how several GStreamer decoders can be used with these default profiles. "Voice, lossless" may be appropriate only for recording, but not for converting.
