Hi, 

   I have a question regarding the RTSP pipelining
and helix DNA TCK v2.0. 


 According to Helix TCK , what is RTSP pipeling ?



RTSP Pipelining is defined as "multiple RTSP methods being sent by
the client without needing to wait for responses from the
server".



By default with
helix Server SETUP, PLAY & SET_PARAMETER  messages are
pipelined.  But I noticed a feature flag
HELIX_FEATURE_PIPELINED_DESCRIBE which pipelines Describe and Options
message. ; 



To pass the compatibility test for RTSP pipelining, Should
the Describe-Option pipeline feature be enabled ?



No.





By the way is
Describe-Option pipeline a standard feature (Does other servers support
it )? 


No, this is a Helix Client-to-Helix Server feature only. Helix Clients
will not try this with other servers or if appropriate preferences are
set to disable it.


Thanks,

Rishi.





Thanks,


Rajesh.

    Hi Rishi,

   Thanks for your response. I have one more 
question.


 


The RTSP pipelining is enabled by default. But the code 
seems to disable the pipeline if the server is not Helix / Real Server. So what 
does it mean to TCK compliance ? Just the capability to RTSP pipeline with Helix 
/ Real server fine for TCK Compliance ?


 


Thanks,


Rajesh.


 


In rtsprtspclnt.cpp


==============


 if( pViaHeader )
    
{
     ;   MIMEHeaderValue* pViaValue = 
pViaHeader->getFirstHeaderValue();
        
while( pViaValue )
       ; 
{
     ;       
pViaValue->asString(it);
        ;    
if( -1 == it.Find("RealProxy") 
)
     ;       
{
     ;           
//This is a non-Real proxy. Only real proxies are known to 
work
          ;      
//with RTSP piplining. If you find another, add it 
here.
        ;        
m_bPipelineRTSP = 
FALSE;
      ;      
}
     ;       //Test 
for NetCache 
appliance.
         ;   
if( -1 != it.Find("NetCache NetApp") 
)
     ;       
{
     ;           
//Found at least one NetCache 
Proxy.
      ;          
m_bTrimTrailingSlashes = 
TRUE;
        ;        
break;
      ;      
}
     ;       
pViaValue = 
pViaHeader->getNextHeaderValue();
 ;       
}
    }
    //We also turn off RTSP 
pipelining if this is not a realserver(helix).
    if( 
!IsRealServer() )
    
{
     ;   m_bPipelineRTSP = 
FALSE;
    }
