[gst-devel] G711 & G726 payload packetizer merging

[Kumar]

Hi Wim,

I am trying to stream G726 16,24,32,40kbps from gstreamer to VLC . 16 & 32
works fine but 24 & 40kbps is not proper(noisy).

The pipeline that I am using is:

Working:
gst-launch-0.10 gstrtpbin name=rtpbin filesrc
location=/home/ES_G726_32kbps.G726  ! audio/x-adpcm, rate=8000, channels=1,
bitrate=32000, layout=g726 !  rtpg726pay  ! rtpbin.send_rtp_sink_2
rtpbin.send_rtp_src_2 ! udpsink port=5002 host=10.60.3.96 name=vrtpsink
rtpbin.send_rtcp_src_2 ! udpsink port=5002 host=10.60.3.96 sync=false
name=vrtcpsink udpsrc port=5002 name=vrtpsrc ! rtpbin.recv_rtcp_sink_2


Noisy:
1) gst-launch-0.10 gstrtpbin name=rtpbin filesrc
location=/home/ES_G726_24kbps.G726  ! audio/x-adpcm, rate=8000, channels=1,
bitrate=24000, layout=g726 !  rtpg726pay  ! rtpbin.send_rtp_sink_2
rtpbin.send_rtp_src_2 ! udpsink port=5002 host=10.60.3.96 name=vrtpsink
rtpbin.send_rtcp_src_2 ! udpsink port=5002 host=10.60.3.96 sync=false
name=vrtcpsink udpsrc port=5002 name=vrtpsrc ! rtpbin.recv_rtcp_sink_2


2) gst-launch-0.10 gstrtpbin name=rtpbin filesrc
location=/home/ES_G726_40kbps.G726  ! audio/x-adpcm, rate=8000, channels=1,
bitrate=40000, layout=g726 !  rtpg726pay  ! rtpbin.send_rtp_sink_2
rtpbin.send_rtp_src_2 ! udpsink port=5002 host=10.60.3.96 name=vrtpsink
rtpbin.send_rtcp_src_2 ! udpsink port=5002 host=10.60.3.96 sync=false
name=vrtcpsink udpsrc port=5002 name=vrtpsrc ! rtpbin.recv_rtcp_sink_2

Whats is wrong in this pipeline?

Thanks,
Kumar KM

rtppcma(de)pay/rtppcmu(de)pay are the G.711 a-law and mu-law
(de)payloaders respectively.
