This software includes functionality for developing RTSP clients (and includes two demo RTSP client applications: “openRTSP” and “testRTSPClient”). However, you have chosen (for “some reasons") not to use our software to develop your RTSP client application. Therefore, your question is off-topic for this mailing list.</div><div><br class=""></div><div>Your second question, however, is relevant:</div><div><br class=""><blockquote type="cite" class=""><div class="WordSection1" style="page: WordSection1; font-family: Helvetica; font-size: 14px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px;"><div style="margin: 0cm 0cm 0.0001pt; text-align: left; font-size: 10pt; font-family: 맑은고딕; background-color: white;" class=""><span style="color: rgb(34, 34, 34); font-family: Arial, sans-serif; font-size: 10.5pt;" class="">Question 2) </span></div><div style="margin: 0cm 0cm 0.0001pt; text-align: left; font-size: 10pt; font-family: 맑은고딕; background-color: white;" class=""><span lang="EN-US" style="font-size: 10.5pt; font-family: Arial, sans-serif; color: rgb(34, 34, 34);" class="">When I stream TS file with audio and video from VLC, its SDP shows audio and video media description separately.<o:p class=""></o:p></span></div><div style="margin: 0cm 0cm 0.0001pt; text-align: left; font-size: 10pt; font-family: 맑은고딕; background-color: white;" class=""><span lang="EN-US" style="font-size: 10.5pt; font-family: Arial, sans-serif; color: rgb(34, 34, 34);" class="">But when I stream the same file from live555 media server, SDP only shows video media,<o:p class=""></o:p></span></div><div style="margin: 0cm 0cm 0.0001pt; text-align: left; font-size: 10pt; font-family: 맑은고딕; background-color: white;" class=""><span lang="EN-US" style="font-size: 10.5pt; font-family: Arial, sans-serif; color: rgb(34, 34, 34);" class="">in this case I can hear audio, and when I save output with -v option(video only) in openRTSP, <o:p class=""></o:p></span></div><div style="margin: 0cm 0cm 0.0001pt; text-align: left; font-size: 10pt; font-family: 맑은고딕; background-color: white;" class=""><span lang="EN-US" style="font-size: 10.5pt; font-family: Arial, sans-serif; color: rgb(34, 34, 34);" class="">output file also has the audio track.<o:p class=""></o:p></span></div><div style="margin: 0cm 0cm 0.0001pt; text-align: left; font-size: 10pt; font-family: 맑은고딕; background-color: white;" class=""><span lang="EN-US" style="font-size: 10.5pt; font-family: Arial, sans-serif; color: rgb(34, 34, 34);" class="">Why does this happen? </span></div></div></blockquote><div><br class=""></div></div>Because when our RTSP server streams a Transport Stream file over RTP, it does so by streaming the entire Transport Stream (including video, audio, etc. tracks) over RTP. It does *not* break up the input Transport Stream into separate video and audio streams and stream each of those - which apparently is what VLC does.<br class=""><br class=""><div apple-content-edited="true" class="">
