int flex_rtmp_tunneled_send( const char *stepname, "SessionID=<session identifier>", ["Snapshot=<snapshot_file>",] ["ContinueToNextStepAfter=<msec>",] [ContinueMode=<AbsoluteTimestamp|DeltaFromNow>,] MESSAGE, "DataType=<data_type>",["EventType=<type>,"] "ChunkStreamID=<id>", "MessageStreamID=<stream>","Argument=<argument>", MESSAGE, ... ... ...

This function returns LR_PASS (0) on success or LR_FAIL (1) on failure. Note that LR_PASS and LR_FAIL generally indicate whether the function call completed without an exception, and not that the test step succeeded.
All input string arguments (char type) except the step name can be parameterized using standard parameterization.
|stepname||A descriptive, unique name for this step. Use any text. Mandatory.|
|SessionID||The unique name of the session on which this function operates. Mandatory.|
|Snapshot||The name of the snapshot file (for example,
|ContinueToNextStepAfter||Used only with streaming media. The minimum play duration of the stream to download before continuing to the next step (milliseconds). How the duration is interpreted depends on the ContinueMode argument. See below, Continue Mode.|
|MESSAGE||The delimiter marking the beginning of the arguments that contain message information. At least one message must be specified.|
|DataType||The data type for control messages is one of:
|EventType||The event type applies to User Control Message data type.
|ChunkStreamID||The position of the chunk within the transmission. Mandatory.Mandatory for all general mesage data types.Cannot be used with control message data types.See DataType in this table.|
|MessageStreamID||The RTMP stream ID. Mandatory for all general mesage data types.Cannot be used with control message data types.See DataType in this table.|
|Argument||The RTMP data containing the body of the message (meaning, the contents that are being sent in the packet). The type of information specified in Argument is dependent on the DataType of the individual server response.Cannot be used with control message data types.See DataType in this table.|
|LAST||The delimiter marking the end of the argument list.|
The flex_rtmp_tunneled_send function sends a message to a server once a connection has been established.
Make sure the flex_rtmp_tunneled_connect function is called before the first call to the script using the flex_rtmp_tunneled_send function.
The data returned from the server is stored in the snapshot.
Each chunk of the streaming feed has a time stamp indicating play duration from the beginning of the stream. When downloading a clip, the initial time stamp is generally 0. When downloading a live feed, the initial time stamp received depends on how long the feed has been working at the time this Vuser begins receiving the stream. When resuming a paused stream, the initial time stamp depends on when the Pause was sent.
ContinueMode=AbsoluteTimestamp or if no mode is specified, then after a time stamp having the ContinueToNextStepAfter value or greater is received, the script run proceeds to the next step.
For example, if a movie is downloading and
ContinueToNextStepAfter=60000, flex_rtmp_tunneled_send returns and the script continues to the next step after enough of the stream has downloaded for the movie to run for at least one minute.The stream may continue in the background on the same socket, but this will not be reflected in the logs.
ContinueMode=DeltaFromNow, then LoadRunner Professional saves the first time stamp received. This function returns when a time stamp of at least the initial time stamp plus the ContinueToNextStepAfter value is received.
ContinueToNextStepAfter=60000. The first time stamp received from a live stream is 100,000. flex_rtmp_tunneled_send returns and the script continues to the next step after a time stamp of 160,000 or greater is received.
