<blockquote type="cite" cite><font face="Times New Roman">I use the
VLC of videolan.org as Encoder for Live streams. These

Live streams shall be sent to a helix server. Unfortunately, the VLC
cannot make any RTCP packages.</font></blockquote>
<div><br></div>
<div>That's because VLC - when used as a RTP *transmitter* - uses a
quick-and-dirty, custom implementation of RTP (*not* the "LIVE555
Streaming Media" code) that does not include RTCP. (VLC
uses the LIVE555 code only when it is used as a
receiver/player.)</div>

<blockquote type="cite" cite><font face="Times New Roman">These are
needed by the helix server.</font></blockquote>
<blockquote type="cite" cite><font face="Times New Roman">The
Helixcommuntity wrote me:<br>
"You could write a program that receives and relays VLC's RTP
packets to the server and generates appropriate RTCP packets and sends
those, too. "</font></blockquote>
<blockquote type="cite" cite><font face="Times New Roman">Is this
possible with live libraries?</font></blockquote>
<div><br></div>
<div>Perhaps. But it would be much better (and probably simpler)
to use our own RTSP/RTP server implementation, with FFMPEG (e.g.) used
as an encoder.</div>
