UNable to create pipeline

Preamble ======= 1 - I have an ogg file with a single stream of a 4 channel vorbis encoded content captured with a format of: - rate=22050, - channels=4, - width=16,
- depth=16, - signed=true and - endianness=1234. 2 - Using following versions: On Ubuntu (server): GStreamer Core Library (as reported by gst-launch --gst-version) - 0.10.28
filesrc - 0.10.28 oggdemux - 0.10.28 vorbisdec - 0.10.28 queue - 0.10.28 deinterleave - 0.10.21 adder - 0.10.28 audioconvert - 0.10.28
audioresample - 0.10.28 celtenc - 0.10.18 udpsink - 0.10.21 rtpceltpay - 0.10.21 On Mac (client): GStreamer Core Library (as reported by gst-launch --gst-version) - 0.10.29
udpsrc - 0.10.23 celtdec - 0.10.19 audioconvert - 0.10.29 osxaudiosink - 0.10.23 rtpceltdepay - 0.10.23 Observation
========= When I do the following pipelines (as long as client is started first), pipelines are created and correct audio is heard on the client (thank goodness for having a simple network :) ):
Server (Ubuntu): gst-launch -v filesrc location='4chan.ogg' ! oggdemux ! vorbisdec ! queue ! deinterleave name=d0 \ adder name=a ! audioconvert ! audioresample ! audio/x-raw-int,width=16,depth=16,rate=32000,channels=2 ! celtenc ! udpsink host=<clientip> port=5555 \
d0. ! queue ! volume name=c1v ! audiopanorama panorama=0.0 ! a. \ d0. ! queue ! volume name=c2v ! audiopanorama panorama=0.0 ! a. \ d0. ! queue ! volume name=c3v ! audiopanorama panorama=0.0 ! a. \
d0. ! queue ! volume name=c4v ! audiopanorama panorama=0.0 ! a. Client (Mac): gst-launch -v udpsrc port=5555 caps="audio/x-celt,rate=32000" ! celtdec ! audioconvert ! osxaudiosink
When I add the rtpcelt(de)pay in the chain it fails to create the server pipeline with an error (actual error line follows pipeline description further down). As follows:
Server (Unsuccessful): gst-launch -v filesrc location='4chan.ogg' ! oggdemux ! vorbisdec ! queue ! deinterleave name=d0 \ adder name=a ! audioconvert ! audioresample ! audio/x-raw-int,width=16,depth=16,rate=32000,channels=2 ! celtenc ! rtpceltpay ! udpsink host=<clientip> port=5555 \
d0. ! queue ! volume name=v0 ! audiopanorama panorama=0.0 name=p0 ! a. \ d0. ! queue ! volume name=v1 ! audiopanorama panorama=0.0 name=p1 ! a. \ d0. ! queue ! volume name=v2 ! audiopanorama panorama=0.0 name=p2 ! a. \
d0. ! queue ! volume name=v3 ! audiopanorama panorama=0.0 name=p3 ! a. Error diplayed (eventhough -v is used): WARNING: erroneous pipeline: could not link p0 to a
Client (Mac): gst-launch -v udpsrc port=5555 caps="application/x-rtp,clock-rate=32000" ! rtpceltdepay ! celtdec ! audioconvert ! osxaudiosink The client pipeline is created successfully and does produce correct audio when a successful server pipeline is able to be generated. I was able to create a successful server pipeline by removing the audiopanorama elements, as follows (notice that the stream is now mono):
Server(Successful): gst-launch -v filesrc location='4chan.ogg' ! oggdemux ! vorbisdec ! queue ! deinterleave name=d0 \ adder name=a ! audioconvert ! audioresample ! audio/x-raw-int,width=16,depth=16,rate=32000,channels=1 ! celtenc ! rtpceltpay ! udpsink host=<clientip> port=5555 \
d0. ! queue ! volume name=v0 ! a. \ d0. ! queue ! volume name=v1 ! a. \ d0. ! queue ! volume name=v2 ! a. \ d0. ! queue ! volume name=v3 ! a.
Clien(Mac - as before): gst-launch -v udpsrc port=5555 caps="application/x-rtp,clock-rate=32000" ! rtpceltdepay ! celtdec ! audioconvert ! osxaudiosink
I have tried all sorts of combination of caps filters and audioconverters in the server pipeline but to no avail. I also tried to create the server pipeline on the Mac which appears to have later versions than the Ubuntu 10.04 distribution but again same error.
I also tried the following: gst-launch -v filesrc location='4chan.ogg' ! oggdemux ! vorbisdec ! queue ! deinterleave name=d0 ! queue ! volume name=v0 ! audiopanorama name=p0 ! \
adder name=a ! audioconvert ! audioresample ! audio/x-raw-int,width=16,depth=16,rate=32000,channels=2 ! celtenc ! rtpceltpay ! udpsink host=192.168.1.14 port=5555 \ d0. ! queue ! volume name=v1 ! audiopanorama name=p1 ! a. \
d0. ! queue ! volume name=v2 ! audiopanorama name=p2 ! a. \ d0. ! queue ! volume name=v3 ! audiopanorama name=p3 ! a. But still fails with:
WARNING: erroneous pipeline: could not link p1 to a notice p0 changed to p1 - might be a clue? Conclusion? ========= I was wondering if this is indeed a bug or is it the way I am constructing the pipeline or my usage of rtp(de)pay elements?
Thanks in Advance, Alfred PS I have included a bzip2 file of the text file (and decolorized) produced by using: GST_DEBUG=4 GST_DEBUG_NO_COLOR=1 gst-launch 2>err.txt -v ....
if you search for 'ERROR' it will take you to the area of the text file where gstreamer couldn't work it out. ------------------------------------------------------------------------------ Sell apps to millions through the Intel(R) Atom(Tm) Developer Program Be part of this innovative community and reach millions of netbook users worldwide.
