[cogniti]

Package: gstreamer0.10-ffmpeg
Version: 0.10.4-3
Severity: important

Original file: original.wav
$ ls -l original.wav
-rw-r--r-- 1 user user 671890796 2009-09-22 21:36 original.wav
$ sha1sum original.wav
a458caae67e14f34233db66fc03a6536a5c70baa  original.wav

$ mac original.wav CDImage.ape -c2000
$ mac CDImage.ape mac.wav -d
$ sha1sum *.wav
a458caae67e14f34233db66fc03a6536a5c70baa  mac.wav
a458caae67e14f34233db66fc03a6536a5c70baa  original.wav

BUT,
After converting CDImage.ape into CDImage.wav using SoundConverter 1.3.1
and gstreamer-ffmpeg  0.10.4-3
(CDImage.ape --> CDImage.wav)

$ sha1sum *.wav
264a891d8ee826be4060a7495a2a49724239346c  CDImage.wav
a458caae67e14f34233db66fc03a6536a5c70baa  mac.wav
a458caae67e14f34233db66fc03a6536a5c70baa  original.wav

$ ls -l
-rw-r--r-- 1 user user 241330948 2009-09-22 23:29 CDImage.ape
-rw-r--r-- 1 user user 655375724 2009-09-22 23:31 CDImage.wav
-rw-r--r-- 1 user user 671890796 2009-09-22 23:26 mac.wav
-rw-r--r-- 1 user user 671890796 2009-09-22 21:36 original.wav

original.wav and CDImage.wav are not same.
