        I don't get more detail reply , I think&nbsp; my description is not 
enough clear,&nbsp; &nbsp;so after rearrange my word, I submit&nbsp; it again.
</p>
<p>
        [1]<br />
i have implemented a RTSP Server(like proxy server), packetizing the audio and 
video stream to TS from EasyDarwin
</p>
<p>
        <br />
</p>
<p>
        [2]<br />
if only have h264 or only have ADTS&nbsp; AAC stream VLC play is ok.
</p>
<p>
        <br />
</p>
<p>
        [3]<br />
but mixed h264 and ADTS AAC together, after a few seconds VLC only play 
video.<br />
audio packet will be lost, i see it from the VLC [current media information] 
dialog -&gt; [statistics] tab -&gt; Lost.

my audio stream code as ADTSAudioFileSource
</p>

        <br />

        [5]<br />
my h264 code snippet is&nbsp; in below<br />
&nbsp;void BlockSource::doGetNextFrame()<br />
&nbsp;{<br />
&nbsp;&nbsp;if (_bFirst)<br />
&nbsp;&nbsp;{<br />
&nbsp;&nbsp;&nbsp;fFrameSize = 
MyExchangeBuffer::Inst().readFirstFromVideoBlock(_strBlockName.c_str(), fTo, 
fMaxSize);<br />
&nbsp;&nbsp;&nbsp;_bFirst = false;<br />
&nbsp;&nbsp;}<br />
&nbsp;&nbsp;else<br />
&nbsp;&nbsp;{<br />
&nbsp;&nbsp;&nbsp;fFrameSize = 
MyExchangeBuffer::Inst().readFromVideoBlock(_strBlockName.c_str(), 
_pBlockChunkPointer, fTo, fMaxSize);<br />
&nbsp;&nbsp;}
</p>
<p>
        &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<br />
&nbsp;&nbsp;gettimeofday(&amp;fPresentationTime, NULL);//i dont know how to set 
it correctly...<br />
&nbsp;&nbsp;fDurationInMicroseconds = 1000000 / 22;//i dont know how to dynamic 
set it, so i set it to 22 fps.
</p>
<p>
        &nbsp;&nbsp;nextTask() = 
envir().taskScheduler().scheduleDelayedTask(fDurationInMicroseconds,<br />
&nbsp;&nbsp;&nbsp;(TaskFunc*)FramedSource::afterGetting, this);<br />
&nbsp;}
</p>
<p>
        <br />

<p>
        [7]<br />
&nbsp;//pBlockName is a string.<br />
&nbsp;sms-&gt;addSubsession(kagula::TSFromH264BlockServerMediaSubsession::createNew(env,
