AIFF and FLAC break GStreamer pipeline

[Michael Schwendt]

SoundConverter recognizes AIFF files, but upon converting them fails with a "GStreamer Error". For brevity, I don't include the debug output, but just the attempt at running the pipeline manually:

  $ gst-launch-0.10 giosrc location="file:///home/ms19/Music/test/love_theme.aiff" name=src ! decodebin name=decoder ! audiorate ! audioresample ! audioconvert ! audio/x-raw-int,rate=44100 ! audioresample ! audioconvert ! vorbisenc quality=0.6 ! oggmux ! giosink location="file:///home/ms19/love_theme.ogg"
  Setting pipeline to PAUSED ...
  Pipeline is PREROLLING ...
  ERROR: from element /GstPipeline:pipeline0/GstDecodeBin:decoder/GstAiffParse:aiffparse0: Internal data flow error.
  Additional debug info:
  aiffparse.c(1320): gst_aiff_parse_loop (): /GstPipeline:pipeline0/GstDecodeBin:decoder/GstAiffParse:aiffparse0:
  streaming task paused, reason not-negotiated (-4)
  ERROR: pipeline doesn't want to preroll.
  Setting pipeline to NULL ...
  Freeing pipeline ...

That is with Resampling enabled, but without resampling it also fails due to the "audioresample" element. The chosen pipeline then is:

  launching: 'giosrc location="file:///home/ms19/Music/test/love_theme.aiff" name=src ! decodebin name=decoder ! audiorate ! audioresample ! audioconvert ! vorbisenc quality=0.6 ! oggmux ! giosink location="file:///home/ms19/love_theme.ogg"'

On the contrary, if one reorders the pipeline, it would work:

 $ gst-launch-0.10 giosrc location="file:///home/ms19/Music/test/love_theme.aiff" name=src ! decodebin name=decoder ! audiorate ! audioconvert ! audioresample ! audio/x-raw-int,rate=44100 ! audioconvert ! vorbisenc quality=0.6 ! oggmux ! giosink location="file:///home/ms19/love_theme.ogg"

I've visited the following page for that order: http://www.freedesktop.org/software/gstreamer-sdk/data/docs/latest/gst-plugins-base-plugins-0.10/gst-plugins-base-plugins-audioresample.html

Also converting from FLAC is not possible here (went back Fedora 18 to verify). Attached patch so far doesn't show any side-effects and makes it possible to convert from FLAC and AIFF.

Well, I don't have a file to test, but it sounds right.
