  GStreamer | don't know | Ver: git
           Summary: Rgvolume does not work when a tag other than the one
                    containing replaygain values exist.
           Product: GStreamer
           Version: git
          Platform: Other
        OS/Version: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: don't know
        AssignedTo: gstreamer-bugs at lists.sourceforge.net
        ReportedBy: balachandran_c at rediffmail.com

     GNOME version: Unspecified
   GNOME milestone: Unspecified


Please describe the problem:
In an mp3 file, with multiple metadata tags, the first being an apev2 tag
containing replaygain values (replaygain-track-gain, replaygain-track-peak),
and the second tag containing values like artist, title etc, rgvolume does not
work. It doesn't seem to receive the replaygain tag. This holds true if the
second tag (artist, title...) is either apev2 or id3.

Steps to reproduce:
1. Create a file with one apev2 tag containing title info.

gst-launch alsasrc ! taginject tags="title=test" ! audioconvert ! lame !
apev2mux ! filesink location=firstpass.mp3

2. Add a second tag with replaygain information.

gst-launch filesrc location=firstpass.mp3 ! taginject
tags="replaygain-track-gain=-0.46,replaygain-track-peak=0.856934" ! apev2mux !
filesink location=secondpass.mp3

3. export GST_DEBUG=rgvolume:3

gst-launch -t filesrc location=secondpass.mp3 ! decodebin ! audioconvert !
rgvolume ! fakesink




Actual results:
rgvolume does not set the result gain to match target. it doesn't see the tag
containing replaygain values.


Expected results:
rgvolume should set the result gain to match target.

Does this happen every time?
yes.
