  GStreamer | gst-plugins-bad | Ver: 0.10.21
           Summary: faac cannot guess the correct rate if the stream if it
                    is 8000
           Product: GStreamer
           Version: 0.10.21
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-bad
        AssignedTo: gstreamer-bugs at lists.sourceforge.net
        ReportedBy: jordijp at gmail.com
         QAContact: gstreamer-bugs at lists.sourceforge.net
     GNOME version: Unspecified
   GNOME milestone: Unspecified


Try this two pipelines:

Sender:

gst-launch-0.10 -v audiotestsrc ! mulawenc ! rtppcmupay ! udpsink

Receiver:

gst-launch-0.10 -v udpsrc ! application/x-rtp, media=audio, clock-rate=8000,
payload=0 ! rtppcmudepay ! mulawdec ! audioresample ! audioconvert ! faac !
faad ! alsasink

Then this is what happens:

(...)

/GstPipeline:pipeline0/GstFaac:faac0.GstPad:sink: caps = audio/x-raw-int,
width=(int)16, depth=(int)16, endianness=(int)1234, signed=(boolean)true,
rate=(int)8000, channels=(int)1
ERROR: from element /GstPipeline:pipeline0/GstFaac:faac0: Internal GStreamer
error: negotiation problem.  Please file a bug at
http://bugzilla.gnome.org/enter_bug.cgi?product=GStreamer.
Additional debug info:
gstfaac.c(640): gst_faac_chain (): /GstPipeline:pipeline0/GstFaac:faac0:
failed to negotiate MPEG/AAC format with next element

Workaround:

gst-launch-0.10 -v udpsrc ! application/x-rtp, media=audio, clock-rate=8000,
payload=0 ! rtppcmudepay ! mulawdec ! audioresample ! audio/x-raw-int,
rate=44100 ! audioconvert ! faac ! faad ! alsasink

Using caps seems to solve the problem, although faac according to its
gst-inspect should be able to coupe with rates of 8000.
