test environment – perhaps I wasn’t clear on how I stated my
question:<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>My stream chunks a H264 NAL Unit into multiple FU-A packets
(1<sup>st</sup> packet with the start bit set, many follow and finally last
with the end bit set)<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I want to safeguard my H264VideoRTPSource’d receiver
to ensure that when it first latches onto this stream, that it does not start
to process packets till it gets one with the start bit set<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;

will not get half-complete NAL frames.<o:p></o:p></span></font></p>

build of liveMedia just now and compiled it, had a simple test file that
instantiated a H264VideoRTPSource and a FileSink.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
