(It turned out that there are even some brain-damaged servers that include “GET_PARAMETER” in the list of commands that they *claim* to support (in response to an initial “OPTIONS” command) - but in reality don’t support “GET_PARAMETER” at all.)<div class=""><div class=""><br class=""></div><div class="">So, if VLC were changed to send “OPTIONS” rather than “GET_PARAMETER”, it might be an improvement (but, OTOH, some people would undoubtedly complain)...</div></div><div class=""><br class=""></div><div class="">As an aside, I should point out that servers should really not need to receive *any* of these ‘keep-alive’ commands; they should, instead, be using incoming RTCP “RR” packets - from the client - to let it know that the client is still alive. But unfortunately lots of RTSP servers (including VLC, I think :-) don’t listen to incoming RTCP packets at all.</div><br class=""><br class=""><div apple-content-edited="true" class="">
