Could you please provide an example of DispatcherOneToMany? - webrtc

I want to connect multiple WebRtcEndPoints to one filter, so I want to use DispatcherOneToMany with multiple HubPorts.
I build the pipeline like this:
PlayerEndpoint -> Customized GStreamer Filter -> HubPort –> DispatcherOneToMany -> HubPort -> WebRtcEndpoint
But it doesn't work, I can only see the video in the first browser connected to the WebRtcEndPoint.
I will appreciate it if someone can provide a demo.
Thank you very much!

Questions related to splunk builtin macros in correlation search

I am not sure if this is the appropriate forum to ask this question, but really need help and I am stuck. So here goes : I am exploring splunk enterprise security and was specifically looking into analytic stories and correlation searches.
For example :
Analytic story : Trickbot
Correlation search : Attempt to stop security service
| tstats `security_content_summariesonly` values(Processes.process) as process min(_time) as firstTime max(_time) as lastTime from datamodel=Endpoint.Processes where (Processes.process_name = net.exe OR Processes.process_name = sc.exe) Processes.process="* stop *" by Processes.dest Processes.user Processes.parent_process Processes.process_name Processes.process Processes.process_id Processes.parent_process_id
| `drop_dm_object_name(Processes)`
| `security_content_ctime(firstTime)`
| `security_content_ctime(lastTime)`
|lookup security_services_lookup service as process OUTPUTNEW category, description
| search category=security
| `attempt_to_stop_security_service_filter`
I am trying to understand what exactly this code is doing, but stuck at these macros like security_content_summariesonly, drop_dm_object_name, security_content_ctime, attempt_to_stop_security_service_filter. I can't find definitions for these macros anywhere. I have tried to look into -> settings -> advance search -> macros, but these are not listed there.
Can somebody help ?
If you have access to the host(s) Splunk's running on, you can find the definitions in $SPLUNK_HOME$/etc/*/macros.conf
If you don't have that access, then it's possible you don't have permissions to see the definitions of those macros
However, you can always use the Job Inspector to see how Splunk translates what you type into what it runs
If you have the query in a search window then click on the query and type Shift-CTRL-E to have Splunk expand all of the macros for you.
I can tell you the drop_dm_object_name macro is just rename $1.* as *. The other macros are specific to their app.

Is using Javascript in odoo.fields.HTML possible?

I want to integrate Adobe Captivate Content (Export: index.html, along with src-folder) into ODOO Community Edition v13 e-Learning Module (website_slides).
The slide.slide model already offers slide_type 'webpage' alongside the field 'html_content'.
The field 'html_content' is of type odoo.fields.HTML. To get the requirement stated above to work, I need to embed Javascript in the given html_content. It seems like the JS-scripts are not working. I also tried with a simple Hello World script.
Can someone help?
Best regards,
Lars
I found the solution already.
Looking at odoo/fields.py -> class Html, you can see that by default the given value is being sanitized using odoo/tools/mail.py -> html_sanitize(), which removes the HTML-Elements in 'tags_to_kill'. 'tags_to_kill' also contains "script".
After overriding html_content in slide.slide with the following, the Javascript-code is being executed:
html_content = fields.Html(
sanitize=False,
sanitize_tags=False,
sanitize_attributes=False)

How to comment script in Datamapper Mule

I have a XML to XML mapping in DataMapper. Obviously soon after mapping done script will be present. How to I comment any line in script( Example here output.status line).
I have tried like this // but not seems to be commented.But could see by default Mule commented //MEL.
//MEL
//START -> DO NOT REMOVE
output.__id = input.__id;
//END -> DO NOT REMOVE
output.vendorReference = input.Ref;
output.status = input.overallStatus;
We know can remove the mapping or delete in script. But is there a any way we can comment it. Please suggest. Thanks in advance.
I could not understand why you want to comment the output status line.
Generally the scripting will allow // for commenting. In case of any filtering to be done then there are many features supported by MULE. Can you please elaborate your requirement so that we can help better.
