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. Selected Media-> Open Network Stream ... option.<br>2. entered the url rtp://224.0.1.0:5004 and pressed 'play' button.<br>3. In the ' Messages' window,got messages as
follows<br> .<br> .<br> .<br> .<br> main debug: `rtp://224.0.1.0:5004' successfully opened<br> qt4 debug: IM: Deleting the input<br> main debug: TIMER input launching for 'rtp://224.0.1.0:5004' : 1.862 ms - Total 1.862 ms / 1 intvls (Avg 1.862 ms)<br> qt4 debug: IM: Setting an input<br>4. 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 where and help me to solve the issue.<br><br>Regards,<br>Praveen<br></span></div><div> </div><br></div></body></html>
