GStreamer | don't know | Ver: git
Summary: Rgvolume does not work when a tag other than the one
containing replaygain values exist.
Component: don't know
AssignedTo: gstreamer-bugs at lists.sourceforge.net
ReportedBy: balachandran_c at rediffmail.com
QAContact: gstreamer-bugs at lists.sourceforge.net
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 !
3. export GST_DEBUG=rgvolume:3
gst-launch -t filesrc location=secondpass.mp3 ! decodebin ! audioconvert !
rgvolume ! fakesink
rgvolume does not set the result gain to match target. it doesn't see the tag
containing replaygain values.
rgvolume should set the result gain to match target.
Does this happen every time?
