In IDR frame 511 slice 2 (zero-indexed) you’ll notice the byte sequence “25 00 1f e2 22 00 00 03 02 00 00 80 ab ff ed 5f”.

If you image this data being produced by a live source, then live555 (with the current code) will slow the stream down every time it sees an IDR frame until the escape sequence disappears from the encoded data.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Please let me know if I misunderstood something about live555’s operation here.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Hope this helps,<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Philipp<o:p></o:p></span></p></div></body></html>
