The "H264VideoStreamFramer" (or "H264VideoStreamDiscreteFramer") object - which precedes the "H264VideoRTPSink" object in the data stream - will store copies of the SPS and PPS NAL units when it sees them. Those will get encoded and included in the stream's SDP description (in the response to each client's RTSP "DESCRIBE" command).</div><div><br></div><div><br><blockquote type="cite"><div lang="ZH-CN" link="blue" vlink="purple" style="font-family: Helvetica; font-size: medium; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: -webkit-auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; "><div class="WordSection1" style="page: WordSection1; "><div style="margin: 0cm 0cm 0.0001pt; text-align: justify; font-size: 10.5pt; font-family: Calibri, sans-serif; "><span lang="EN-US"><o:p></o:p></span></div><div style="margin: 0cm 0cm 0.0001pt; text-align: justify; font-size: 10.5pt; font-family: Calibri, sans-serif; "><span lang="EN-US"> Currently if I use VLC to access the rtsp server, in the first time, it would play correctly.
