  GStreamer | gst-plugins-bad | 0.10.25

           Summary: FAAC bitrate setting has no effect
    Classification: Desktop
           Product: GStreamer
           Version: 0.10.25
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-bad
        AssignedTo: gstreamer-bugs at lists.sourceforge.net
        ReportedBy: mike.dyer at provision-comm.com
         QAContact: gstreamer-bugs at lists.sourceforge.net
      GNOME target: ---
     GNOME version: ---


When setting the bitrate on the faac plugin, the resulting bit rate is always
~128kbps

Can reproduce using:

gst-launch -v audiotestsrc is-live=true wave=9 do-timestamp=true
num-buffers=450 ! audio/x-raw-int,channels=2,rate=44100,width=16 !
audioconvert ! faac outputformat=1 profile=2 bitrate=8000 !
ffmux_mpegts ! filesink location=8mbps.ts

gst-launch -v audiotestsrc is-live=true wave=9 do-timestamp=true
num-buffers=450 ! audio/x-raw-int,channels=2,rate=44100,width=16 !
audioconvert ! faac outputformat=1 profile=2 bitrate=128000 !
ffmux_mpegts ! filesink location=128mbps.ts

ls -l *.ts gives:

-rw-rw-r--. 1 mike mike  234436 2010-01-08 10:13 128mbps.ts
-rw-rw-r--. 1 mike mike  232556 2010-01-08 10:13 8mbps.ts

Two files of about the same size, for two very different bitrates.

System is: Fedora Core 12, gstreamer version 0.10.25, gst-plugins-bad version
0.10.17, faac version 1.28
