<span style="white-space:nowrap;"><span style="white-space:nowrap;"><span 
style="white-space:nowrap;">i can not transfer the h264 and ADTS AAC together 
to STB From EasyDarwin</span><br />
<span style="white-space:nowrap;"><br />
</span><span style="white-space:nowrap;">Below is my procedure</span><br />
<span style="white-space:nowrap;"><br />
</span><br />
<span style="white-space:nowrap;">step1:</span><br />
<span style="white-space:nowrap;">ffmpeg -re -stream_loop -1 -i 
D:\h264_and_aac.mp4&nbsp; &nbsp;-rtsp_transport tcp -vcodec copy&nbsp; &nbsp; 
&nbsp; &nbsp; &nbsp; &nbsp; -acodec copy&nbsp; -f rtsp 
rtsp://127.0.0.1:554/test</span><br />
<span style="white-space:nowrap;"><br />
</span><br />
<span style="white-space:nowrap;">step2:</span><br />
<span style="white-space:nowrap;">use RTSPClient code get h264 and aac stream 
from rtsp://127.0.0.1:554/test</span><br />
<span style="white-space:nowrap;"><br />
</span><br />
<span style="white-space:nowrap;">step3:</span><br />
<span style="white-space:nowrap;">i add ADTS header for aac raw data,&nbsp; 
&nbsp;by my test(store it to disk as AAC file then using VLC play) is 
ok.</span><br />
<span style="white-space:nowrap;">and h264 is ok too, by above test.</span><br 
/>
<span style="white-space:nowrap;"><br />
</span><br />
<span style="white-space:nowrap;">step4:</span><br />
<span style="white-space:nowrap;">now i create my RTSPServer for pack these two 
streams to ts, so&nbsp; STB(Set Top Box) can play it because STB only support 
TS.</span><br />
<span style="white-space:nowrap;">i create a media subsession&nbsp; for mix 
these two stream&nbsp; &nbsp;and convert it to TS stream</span><br />
<span style="white-space:nowrap;">#define SUPPORT_AAC_ADTS</span><br />
<span style="white-space:pre;"> </span>FramedSource * 
TSFromH264BlockServerMediaSubsession::createNewStreamSource(unsigned 
/*clientSessionId*/, unsigned &amp; estBitrate)<br />
<span style="white-space:pre;"> </span>{<br />
<span style="white-space:pre;"> </span>estBitrate = 2500; // kbps, estimate<br 
/>
<span style="white-space:nowrap;"><br />
</span><br />
<span style="white-space:pre;"> </span>// Then create a filter that packs the 
H.264 video data and ADTS AAC audio data into a Transport Stream:<br />
<span style="white-space:pre;"> </span>MPEG2TransportStreamFromESSource* 
tsFrames = MPEG2TransportStreamFromESSource::createNew(envir());<br />
<span style="white-space:nowrap;"><br />
</span><br />
<span style="white-space:pre;"> </span>BlockSource* blockSource = 
BlockSource::createNew(envir(), _strBlockName.c_str());//H264 from 
RTSPClient<br />
<span style="white-space:pre;"> </span>if (blockSource == NULL)<br />
<span style="white-space:pre;"> </span>return NULL;<br />
<span style="white-space:pre;"> </span>H264VideoStreamFramer* framer = 
H264VideoStreamFramer::createNew(envir(), blockSource, 
True/*includeStartCodeInOutput*/);<br />
<span style="white-space:pre;"> </span>tsFrames-&gt;addNewVideoSource(framer, 
5/*mpegVersion: H.264*/);<br />
<span style="white-space:nowrap;">#ifdef SUPPORT_AAC_ADTS</span><br />
<span style="white-space:pre;"> </span>AACADTSSource* adtsSource = 
AACADTSSource::createNew(envir(), _strBlockName.c_str());//ADTS AAC from 
RTSPClient<br />
<span style="white-space:nowrap;"><br />
</span><br />
<span style="white-space:pre;"> </span>if (adtsSource != nullptr)<br />
<span style="white-space:pre;"> </span>{<br />
<span style="white-space:pre;"> 
</span>tsFrames-&gt;addNewAudioSource(adtsSource, 4/*mpegVersion: AAC*/);<br />
<span style="white-space:pre;"> </span>}<br />
<span style="white-space:nowrap;">#endif</span><br />
<span style="white-space:pre;"> </span>// Create a framer for the Video 
Elementary Stream:<br />
<span style="white-space:pre;"> </span>return 
MPEG2TransportStreamFramer::createNew(envir(), tsFrames);//blockSource<br />
<span style="white-space:pre;"> </span>}<br />
<span style="white-space:nowrap;"><br />
</span><br />
<span style="white-space:pre;"> </span>RTPSink * 
TSFromH264BlockServerMediaSubsession::createNewRTPSink(Groupsock * 
rtpGroupsock, unsigned char rtpPayloadTypeIfDynamic, FramedSource * 
inputSource)<br />
<span style="white-space:pre;"> </span>{<br />
<span style="white-space:pre;"> </span>return SimpleRTPSink::createNew(envir(), 
rtpGroupsock,<br />
<span style="white-space:pre;"> </span>33, 90000, "video", "MP2T",<br />
<span style="white-space:pre;"> </span>1, True, False /*no 'M' bit*/);<br />
<span style="white-space:pre;"> </span>}<br />
<span style="white-space:pre;"> </span><br />
<span style="white-space:nowrap;">Final step:</span><br />
<span style="white-space:nowrap;">&nbsp;finally i play from&nbsp; my RTSPServer 
in STB</span><br />
<span style="white-space:nowrap;">&nbsp;but only can play audio or only can 
play video,</span><br />
<span style="white-space:nowrap;">&nbsp;if i mix them two only can play audio 
in STB.</span><br />
<span style="white-space:nowrap;">&nbsp;</span><br />
<span style="white-space:nowrap;">&nbsp;</span><br />
<span style="white-space:nowrap;">&nbsp;</span><br />
<span style="white-space:nowrap;">There is going to be the Spring Festival 
after a few days, wish&nbsp; all things are right in the New Year.</span><br />
</span></span><span style="white-space:nowrap;"></span><br />
