<DIV style="RIGHT: auto">I was trying to do rtp streaming of a wave file with trans-coding using VLC. But my client VLC is not decoding sap announcements.<BR>The following are the steps I performed.<BR><BR>At Server VLC<BR>=============<BR>1. In Media->Streaming menu, I gave my Wave file(16bit 44.1KHz Stereo).<BR>2. In the 'Destinations' tab, I selected 'RTP Audio/video Profile' and using 'Add' button, added the multicast IP '224.0.1.0'.<BR>3. In the trans-coding options, I created a new profile with<BR> Codec -> WAV<BR> Channels-> 2<BR> Sample Rate -> 22050<BR>4. In the 'Miscellaneous Options', Gave Tick mark to 'SAP announce', gave 'Test_SDP' in the edit box next to 'SAP announce' and 'Test Group' to 'Group name'.<BR>5. The corresponding output string is <BR><BR> :sout=#transcode{vcodec=none,acodec=s16l,ab=512,channels=2,samplerate=22050}:rtp{dst=224.0.1.0,port=5004}
:sout-rtp-sap :sout-rtp-name=Test_SDP :sout-standard-sap :sout-standard-name=Test_SDP :sout-standard-group=Test_Group :ttl=1 :sout-keep<BR><BR>6. Then pressed 'stream' button.<BR><BR>At Messages Window, I could see the following log(with Verbosity Level - 2)<BR><BR>stream_out_rtp debug: sdp=<BR>v=0<BR>o=- 15154488331352645916 15154488331352645916 IN IP4 localhost.localdomain<BR>s=3<BR>i=N/A<BR>c=IN IP4 224.0.1.0/255<BR>t=0 0<BR>a=tool:vlc 1.1.11<BR>a=recvonly<BR>a=type:broadcast<BR>a=charset:UTF-8<BR>m=audio 5004 RTP/AVP 96<BR>b=AS:705<BR>b=RR:0<BR>a=rtpmap:96 L16/22050/2<BR><BR><BR><BR><BR>At client VLC<BR>=============<BR>1.

In the ' Messages' window,got messages as follows<BR>

But I couldn't hear anything.<BR><BR>I doubt my VLC client is not decoding SAP announcements. But in the Wire-shark at the client terminal, I am able to see the SDP packets(sap announcement)[ I am using VLC 1.1.11 and installed the latest version of live555 plug-in].<BR>Please correct me if I am wrong some wher<VAR id=yui-ie-cursor></VAR>e and help me to solve the issue.<BR><BR>Regards,<BR>Praveen<BR></DIV></div></body></html>
