            Bug ID: 776962
           Summary: Conversion from m4a encapsuled alac to flac fail with:
                    Could not initialize supporting library.
    Classification: Platform
           Product: GStreamer
           Version: unspecified
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: don't know

After trying to debug soundconverter I discovered the problem comes from
gstreamer :

gst-launch-0.10 filesrc location="/home/francois/Bureau/test.m4a" ! queue !
decodebin name=decoder ! audioconvert ! flacenc ! filesink location=test.flac

fail with :

Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
ERROR: from element /GstPipeline:pipeline0/GstFlacEnc:flacenc0: Could not
initialize supporting library.
Additional debug info:
gstflacenc.c(829): gst_flac_enc_set_format ():
/GstPipeline:pipeline0/GstFlacEnc:flacenc0:
could not initialize encoder (wrong parameters?)
ERROR: pipeline doesn't want to preroll.
Setting pipeline to NULL ...
Freeing pipeline ...


But 
gst-launch-0.10 filesrc location="/home/francois/Bureau/test.m4a" ! queue !
decodebin name=decoder ! autoaudiosink 

works

as well as :

gst-launch-0.10 giosrc location="file:///home/francois/Bureau/test.m4a"
name=src ! decodebin name=decoder ! audioconvert ! vorbisenc quality=0.6 !
oggmux  ! giosink location="file:///home/francois/Bureau/test.ogg" 


Verbose output of gst-launch-0.10 -v filesrc
location="/home/francois/Bureau/test.m4a" ! queue ! decodebin name=decoder !
audioconvert ! flacenc ! filesink location=test.flac
