How to stream the audio which will be recorded from microphone and will be encoded in AAC codec format and will be send using RTP packetization?
I have used this code for server: -------------------------------------- #!/bin/sh # # A simple RTP server # change this to send the RTP data and RTCP to another host DEST=127.0.0.1 AELEM=audiotestsrc #AAC encode from the source ASOURCE="$AELEM ! audioconvert" AENC="faac ! rtpmp4gpay " gst-launch -v gstrtpbin name=rtpbin \ $ASOURCE ! $AENC ! rtpbin.send_rtp_sink_0 \ rtpbin.send_rtp_src_0 ! udpsink port=5002 host=$DEST \ rtpbin.send_rtcp_src_0 ! udpsink port=5003 host=$DEST sync=false async=false \ udpsrc port=5007 ! rtpbin.recv_rtcp_sink_0 --------------------- Client code : #!/bin/sh # # A simple RTP receiver AUDIO_CAPS="application/x-rtp,media=(string)audio,clock-rate=(int)44100,encoding-name=(string)MPEG4-GENERIC,encoding-params=(string)1,streamtype=(string)5,profile-level-id=(string)2,mode=(string)AAC-hbr,config=(string)1208,sizelength=(string)13,indexlength=(string)3,indexdeltalength=(string)3,ssrc=(uint)853015980,payload=(int)96,clock-base=(uint)2040203639,seqnum-base=(uint)52067" #AUDIO_CAPS="application/x-rtp, media=(string)audio, clock-rate=(int)44100, encoding-name=(string)MPEG4-GENERIC, encoding-params=(string)1, streamtype=(string)5, profile-level-id=(string)2, mode=(string)AAC-hbr, config=(string)1208, sizelength=(string)13, indexlength=(string)3, indexdeltalength=(string)3, ssrc=(uint)853015980, payload=(int)96, clock-base=(uint)2040203639, seqnum-base=(uint)52067" AUDIO_DEC="rtpmp4gdepay ! faad" AUDIO_SINK="alsasink" # the destination machine to send RTCP to. This is the address of the sender and # is used to send back the RTCP reports of this receiver. If the data is sent # from another machine, change this address. DEST=127.0.0.1 gst-launch -v gstrtpbin name=rtpbin \ udpsrc caps=$AUDIO_CAPS port=5002 ! rtpbin.recv_rtp_sink_0 \ rtpbin. ! $AUDIO_DEC ! $AUDIO_SINK \ udpsrc port=5003 ! rtpbin.recv_rtcp_sink_0 \ rtpbin.send_rtcp_src_0 ! udpsink port=5007 host=$DEST sync=false async=false I am not getting any error, but what I am talking in my Microphone is not streaming.I can hear only beep sound. Please reply. Thanks in advance. _______________________________________________ gstreamer-devel mailing list [hidden email] http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |

Hi,
you hear a sound because you are using audiotestsrc, this elements generates a sin wave, and with the property freq you can vary the frequency of the signal. If you want to use the microphone substitute the AELEM with "autoaudiosrc" or "alsasrc" or "pulsesrc"... I hope it works. cheers Stefano Date: Fri, 15 Jul 2011 22:06:07 -0700 Subject: How to stream audio in network using RTP From: [hidden email] To: [hidden email] How to stream the audio which will be recorded from microphone and will be encoded in AAC codec format and will be send using RTP packetization?
