As I said before: "[You should not be sending] such ridiculously large NAL units. You should reconfigure your encoder to encode each IDR picture (i.e., 'I-frame') into multiple 'slice' NAL units. This is a good idea, because if packets forming a 'slice' NAL unit get lost, then that will cause only that slice to be non-renderable. On the other hand, if the IDR picture is a complete NAL unit, then the loss of *any* packet will cause the whole picture to be non-renderable."<o:p></o:p></span></p></div><div><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p></div><div><p class=MsoNormal><span lang=EN-US>Ross Finlayson<o:p></o:p></span></p></div><div><p class=MsoNormal><span class=apple-style-span><span lang=EN-US style='font-size:13.5pt;font-family:"Helvetica","sans-serif";color:black'>Live Networks, Inc.</span></span><span lang=EN-US style='font-size:13.5pt;font-family:"Helvetica","sans-serif";color:black'><br><span class=apple-style-span><a href="http://www.live555.com/">http://www.live555.com/</a></span></span><span lang=EN-US> <o:p></o:p></span></p></div><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p></div></body></html>
