<p class="MsoNormal"><font color="black" face="Times New Roman"

looking to have real time
transcoding ? Can you tell us a bit more about your exact needs ?<br>
<br>
If you intend to use Asterisk for this, the best starting point is to
get the
app_transcode module from Sergio and customize it to transcode the way
you
want. Sergio also has a media mixer module capable of doing this
outside
asterisk You have to know that:<o:p></o:p></span></font></p>
<ol start="1" type="1">
<li class="MsoNormal" style=""><font color="black"
face="Times New Roman" size="3"><span style="font-size: 12pt;">Using
and transcoding from to MPEG4 part 2 / MPEG4 part 10 is submitted to
licencing so if you intend to put your solution in production, you have
to pay the fee to the MPEG Licencing Authority<o:p></o:p></span></font></li>
<li class="MsoNormal" style=""><font color="black"
face="Times New Roman" size="3"><span style="font-size: 12pt;">Doing
such operation in real time is very costly in term of CPU. Meaning that
the number simultaneous of transcoding will be limited.<o:p></o:p></span></font></li>
