<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>The spec is <b>Amendment 3: Transport of AVC video data over
ITU-T Rec. H.222.0 | ISO/IEC 13818-1 stream</b>. As usual its full of semantic
changes of the original spec and not a streamlined spec ready to be implemented
but at least it’s a direction.<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>AFAIK it says to grab the NAL packets with the start code (so
called byte stream) and push it into TS PES along with service packets like SPS,
PPS, SEI, . The problem is time stamp conversion which looks like a project on
its own. <o:p></o:p></span></p>

<p class=MsoNormal>What you're missing is that you're trying to use code that
reads and streams a MPEG-2 Transport Stream file to instead read and stream a
H.264 Elementary Stream video file. There's no way this can possibly
work.<o:p></o:p></p>
