<p class="MsoNormal">The frames are indent bigger – the camera is HD with a decent bitrate.<o:p></o:p></p>
<p class="MsoNormal">I changed the stack size to 8 MB byte and your software finishes without stack overflow.<o:p></o:p></p>
<p class="MsoNormal">You are working recursively though a larger buffer slicing a TS packet off one at a time resulting into 4k+ size call stack.<o:p></o:p></p>

<p class="MsoNormal">> DO NOT encode your H.264 NAL units to be more than a few 10s of kBytes in size.<o:p></o:p></p>
<p class="MsoNormal">Although this is good advice – I am not the one who is encoding – it’s the hardware in the camera.<o:p></o:p></p>
