But wait - Amino had earlier decided not to use RTP/RTCP at all, but instead to transmit their streams via raw-UDP. So, they are now 'reaping what they have sown', because - without RTP/RTCP - their new, nonstandard "GET_PARAMETER position:" hack is the only way for them to get the stream's NPT from the server. (I also note that - without RTP/RTCP - they have no way to handle network packet reordering (whereas this comes for free with RTP).)</div><div><br></div><div>I would be thrilled if 'Amino' were to upgrade their products to be more standards-compliant (and I would be happy to help them do so, should they desire).</div><div><br></div><div>Failing this, however, I recommend that, instead of using 'Amino' set-top box clients, people use other, more standards-compliant products instead.</div><div><br></div><div>(Note that if anyone does choose to make these (or any other) modifications to the LIVE55 code, then they are bound by the terms of the LGPL; see <<a href="http://www.live555.com/liveMedia/faq.html#copyright-and-license">http://www.live555.com/liveMedia/faq.html#copyright-and-license</a>>.)</div><div><br></div><br><div apple-content-edited="true">
