[gst-devel] replaygain: rgvolume issue

[Gabriel Bouvigne]

I am trying to adjust loudness of tracks using RG levels, from sources 
that do not feature any kind of RG tag.

I am using the fallback-gain property of rgvolume. However, whatever I 
try, it seems to me that this way rgvolume can only decrease loudness, 
but never increase it.

To check it, I am using rganalysis within the pipeline, after rgvolume:

gst-launch -t filesrc location="./ref_pink.wav" ! decodebin ! 
audioconvert ! rgvolume fallback-gain=TEST_VALUE ! rganalysis ! fakesink

With TEST_VALUE as a negative number, rgvolume is working correctly. 
However, with a positive value, rgvolume doesn't change the stream level.

I know that rgvolume is still within the "bad" plugins, but I'm 
wondering if my case is supposed to work or if I did a mistake somewhere.

Regards,
