Proxy server can use GET_PARAMETER command with empty parameter
name as session liveness command.
In function ProxyRTSPClient::sendLivenessCommand (file
ProxyServerMediaSession.cpp)
we see this code:
rtspClient->sendGetParameterCommand(*sess, ::continueAfterGET_PARAMETER, "",
rtspClient->auth());
Here "" means parameter name.
It results in RTSP request to backend server containing "Content-Length" field
without real content.
Some servers (I noted it with VLC 2.0.8, did not check newer version) treat this
as error and return error 451 ("Parameter Not Understood").
I propose to replace "" with NULL. In this case no "Content-Length" field
in RTSP request.
Or modify RTSPClient::sendGetParameterCommand (file RTSPClient.cpp)
to ignore zero length parameter names.
