tsdemux: Delayed linking failed

This post was updated on .
Hi everyone,
Today I try to test fdkaac gstreamer plugin with
Encoder
gst-launch-1.0 audiotestsrc ! audioconvert ! 'audio/x-raw, format=(string)S16LE, rate=(int)48000, channels=(int)2' ! fdkaacenc ! mpegtsmux ! udpsink host=$CLIENT_IP port=5000

Decoder
gst-launch-1.0 udpsrc port=5000 ! tsdemux ! fdkaacdec ! audioconvert ! alsasink device=aux_plug -e


But I got the the error on decoder side
Setting pipeline to PAUSED ...
Pipeline is live and does not need PREROLL ...
Setting pipeline to PLAYING ...
New clock: GstSystemClock
WARNING: from element /GstPipeline:pipeline0/GstTSDemux:tsdemux0: Delayed linking failed.
Additional debug info:

Are there any body got the same problem? Or some one can give me some suggestion?
Thank in advance.
P.S.: I tested with faac and faad, it works normally but not fdkaac

Try adding an aacparse before the decoder.

Cheers

Hi Tim,
I try to add aacparse before the decoder, but I got the same error.
Do you have other suggestion?
Thank,
Quang
