[gst-devel] state change problem on udpsink element

[Jyoti D]

Hi all,

I am writing an application for UDP multicast server. I use the below
pipelines for server & client.

SERVER:
gst-launch filesrc location=~/Desktop/h264-aac/alien.mp4 ! qtdemux name=d \
d. ! queue ! rtph264pay ! udpsink port=1234 host=224.0.0.1 \
d. ! queue ! rtpmp4apay ! udpsink port=1233 host=224.0.0.1

CLIENT:
gst-launch udpsrc uri=udp://224.0.0.1:1234 caps="application/x-rtp,
media=(string)video, encoding-name=(string)H264, payload=(int)96"  ! queue !
rtph264depay ! ffdec_h264 ! ffmpegcolorspace ! xvimagesink\
udpsrc uri=udp://224.0.0.1:1233 caps="application/x-rtp,
media=(string)audio, clock-rate=(int)44100, encoding-name=(string)MP4A-LATM,
payload=(int)96" ! queue ! rtpmp4adepay ! faad ! audioconvert ! alsasink

The pipeline works fine. But when I am writing an application for the above
pipeline
the pipeline doesn't change its state to "PLAYING". I state change on the
pipeline
is "GST_STATE_CHANGE_ASYNC".

The pipeline never changes its state to "PLAYING".

But when if I change my application to send either video or audio packets
alone the
application works fine with proper state changes.

I will be thankful for any help.
