<p class="MsoNormal">Hi Team ,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We are using Live555 library as a RTSP client in our CCTV product. Recently we started supporting high bitrate cameras.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">For some cameras(25 FPS/25 GOP, 8Mbps bit rate, 8MP resolution) we noticed that video is showing artifacts, on further analysis we identified that I Frame is missed for a some GOPs in between(In a 60 GOPs two to three GOPs I Frames are
missed).<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">When captured Wireshark between camera and system, able to all frames are available in wireshark dump.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We played the rtsp url in OpenRTSP command line tool and observed similar issue in the video dump file. But we did not see any error in the console.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">This is the command used, OpenRTSP.exe -v -b 600000 -P 60 <rtsp_url>.<o:p></o:p></p>
<p class="MsoNormal">Since this is high bitrate camera I Frame size is around 500KB, so given a client buffer size of 600000.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Please share your input.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks and Regards,<o:p></o:p></p>
