Description Zaheer Abbas Merali 2005-02-13 15:43:13 UTC 
Compare:

gst-launch-0.8 -v alsasrc ! audio/x-raw-int,rate=44100,channels=2 ! audioconvert
! audio/x-raw-int,channels=1 ! lame bitrate=16 ! filesink location=blah.mp3

and

gst-launch-0.8 -v alsasrc ! audio/x-raw-int,rate=44100,channels=1 ! lame
bitrate=16 ! filesink location=blah2.mp3

first one sounds like eerie silence even when talking into your mic, second one
is fine.

        * gst/audioconvert/gstchannelmix.h:
          include missing header file
        * gst/audioconvert/gstchannelmix.c:
        (gst_audio_convert_fill_compatible):
          use same sign for both channels when converting to/from compatible
          channel. Previously used different signs made the signals cancel
          each other out and appear like silence. (fixes #167269)
