LoadRunner/VuGen supports both Web (HTTP/HTML) virtual users and Media Player (MMS) vusers, but it does not allow you to create a multiple protocol script using these two protocols.
Fortunately, with a little bit of hacking, you can create a multi-protocol vuser with these two protocols yourself.
The steps to follow are:
- Record your application using the Media Player (MMS) vuser. A typical application might be a webpage with a Windows streaming media component.
- Record your application using the Web (HTTP/HTML) vuser type. Put lots of comments in your script to help you when merging the scripts.
- Merge the scripts. Cut and paste the code from MMS script into the Web script in the appropriate places. In the globals.h file, add #include "mic_media.h"
If you try to run the script at this point, you will get the following error on replay:
Running Vuser...
Starting iteration 1.
Starting action Action.
Action.c(5): Registering web_reg_save_param was successful [MsgId: MMSG-26390]
Action.c(12): web_url("Games") was successful, 114051 body bytes, 229 header bytes, 117 chunking overhead bytes [MsgId: MMSG-26385]
Action.c(39): Notify: Transaction "test" started.
Action.c(41): Error: C interpreter run time error: Action.c (41): Error -- Unresolved symbol : mms_play.
Action.c(41): Notify: CCI trace: Compiled_code(0): Action()
.
Notify: Transaction "test" ended with "Stop" status (Duration: 0.0524).
Ending Vuser...
The Replay Engine cannot find the function named mms_play. This can be fixed by modifying the *.usr file to include the MMS protocol.
Change all occurrences of "QTWeb" to "MMS,QTWeb":
Change [General]
Type=Multi
AdditionalTypes=MMS,QTWeb
ActiveTypes=MMS,QTWeb
GenerateTypes=MMS,QTWeb
It really is that simple...
Note that to replay successfully in the LoadRunner Controller, you must still be licensed for both virtual user types.

Hi,
I tried to follow the steps and included #include mic_media.h into Globals.h
On replay, it fails throwing “Unable to resolve mms_play” error. I’m unable to follow the next step. Exactly which file should I modify to include MMS,QTWeb.
Pls suggest.
