  GStreamer | don't know | Ver: 0.10.22
           Summary: APE file metadata not retained during transcode
           Product: GStreamer
           Version: 0.10.22
          Platform: Other
        OS/Version: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: don't know
        AssignedTo: gstreamer-bugs at lists.sourceforge.net
        ReportedBy: rigel_23 at hotmail.com
         QAContact: gstreamer-bugs at lists.sourceforge.net
     GNOME version: 2.25/2.26
   GNOME milestone: Unspecified


Please describe the problem:
APE file metadata is not retained when converting to flac. (also to ogg, but i
have tested that conversion less extensively)

Steps to reproduce:
1. gst-launch-0.10 filesrc location="14 - When DId You Stop Loving Me, When Did
I Stop Loving You (Reprise).ape" ! decodebin ! fakesink -t

will display the metadata/tag information for the ape file

2. gst-launch-0.10 -v filesrc location="14 - When DId You Stop Loving Me, When
Did I Stop Loving You (Reprise).ape" ! decodebin ! audioconvert ! flacenc
quality=8 ! filesink location="./test.flac"

this will convert the file to flac but the metadata is not retained.
3. 


Actual results:
the file is converted to flac, but no metadata is added to the file. this
includes the flac bitrate, which the encoding should be tagged with anyway.

Expected results:
that the file would convert and convert the tags to vorbis comments.

Does this happen every time?
yes

Other information:
$ gst-launch-0.10 -v filesrc location="14 - When DId You Stop Loving Me, When
Did I Stop Loving You (Reprise).ape" ! decodebin ! audioconvert ! flacenc
quality=8 ! filesink location="./test.flac"

__tim (t. i. m @ zen co uk) from #gstreamer has been provided with a copy of
the ape file for testing purposes.

tags were set by EasyTAG. many do not show up in soundconverter (which uses the
GStreamer framework) for some reason.
