           Summary: Gstreamer: no sound on some "pps" files
    Classification: Platform
           Product: GStreamer
           Version: 1.x
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gstreamer (core)

     GNOME version: ---


SYSTEM
(B)LFS system, i686-pc-linux-gnu, kernel-3.13.3
libreoffice-4.2.0.4.  Compiled (configured) with
   --disable-gstreamer-0.10 --enable-gstreamer
   (i.e., enable gstreamer 1.2.3 instead of gstreamer 0.x)
 gstreamer-1.2.3 compiled from sources
  (with its complement of plugins, base-, good- bad- and ugly-1.2.3)

 lame-3.99.5
 twolame-0.3.13
 gst-ffmpeg-0.10.13
 ffmpeg-2.0.2

PROBLEM
 Two "pps" slide files (from a third party) with video/audio:
  'watermelons.pps' and 'plague.pps'
 Run in LibreOffice:
  'plague.pps':  sound OK
  'watermelons.pps':  NO sound  (the PROBLEM)

MY INVESTIGATION
I decomposed the two files;  sound in a "WAV" file

In playing each with MPlayer 1.1-4.7.0 (both sound OK):

1.  plague.wav (of the "good" pps):
libavformat version 54.6.100 (internal)
Audio only file format detected.

2.  watermelons.wav (of the "bad" pps):
libavformat version 54.6.100 (internal)
Audio only file format detected.
Load subtitles in watermel/
==========================================================================
Opening audio decoder: [ffmpeg] FFmpeg/libavcodec audio decoders
libavcodec version 54.23.100 (internal)
AUDIO: 8000 Hz, 2 ch, s16le, 64.9 kbit/25.34% (ratio: 8110->32000)
