Advanced Scene Switcher 1.28.1

[Warmuptill]

Dear Warmuptill,

Thanks for your promt reply. I will check this sollution.
During the livestream I am recording the entire stream as backup. The replay buffer is used as instand replay and to show highlights during the breaks. It will be nice if the highlight in the break are only from the previous period.
With the sollution you have. The backup stream will also be devided into four recordings.

It would be great if only the replay buffer path could be changed in the replay buffer file prefix.

I don't think the recording will be stopped when you change the output folder or stop the replay buffer.
(At least it does not appear to be the case in my testing setup)

If that should be the case I can't really think of a good solution as the output location for replay buffer videos is based on the recording output path.

Good evening everyone, sorry for the question guys, but I can't find a tutorial for changing webcams. I only find it for older versions, not for 1.26.2.
Could anyone direct me, even on YouTube there are only old videos.
Basically I have to make Obs change webcam every 10 seconds. Can anyone tell me the macros or direct me.
Thank you

It depends a bit on your setup, but I guess a macro like this might do the trick, assuming you have two sources named "Camera 1" and "Camera 2".

Let me know if you need further help! :)

Thank you very much indeed!! You have solved the problem, in my opinion we will have to highlight the post because I assure you that the resolution is not obvious and there is no information around about it for this version of OBS!
Thanks so much again, very kind!

Good morning everyone. Ran into a problem this morning while uploading settings from one computer to a new computer. This problem is preventing midi support. Used the advanced-scene-switcher-1.26.2-windows-x64-Installer.exe for installation. The old computer used advanced scene switcher version 1.23.0, the new computer version 1.26.2. After installation and running adv-ss get this obs error.

There'll be a more obvious one in the next version, with Timer condition. Then you can store camera source names in 2 vars and alternate them with newly added Variable swap action and show one var and hide the other (press the cog wheel to change type of scene item to Variable). 1 straightforward condition and 3 actions.

Something like

My macros got corrupted recently, rebuilding from an older backup. Am I doing something wrong or does adv-ss not work the same way as before? I have macros that get ignored if there is a and/or condition (it wont launch unless its JUST an if statement, which is too broad for my use case) , there is macros that will launch if you go to sceneC from sceneA but if you go to sceneC from sceneB it wont launch... This is all stuff that worked previously...

Sometimes I wonder if its like, when I restored the old macros... maybe the plugin doesn't see all the settings even though they are all filled out? For example, some filter commands got lost and went blank on me. For the most part everything else was fine, or is it? Would it require going through and deleting each condition/action and remaking it in the UI for it to work correctly again? Or did you change how things get watched for/activate? maybe need clean install?

That sounds very strange.
Can you provide concrete (and if possible simple) example of a condition that does not work? If possible can you export that macro?

I have mostly changed them already, creating or trying to create work-arounds...

Its seems much slower too to react, I think I am gonna do a clean obs/plugins install and see if anything changes, its either
that or maybe my 7th gen pc is dieing...

Very long thread. Amazing plugin. Can anyone point me to the info needed to have a midi controllers dial or pot be able to control the OBS 3 band EQ filter? I have an Akai MidiMix and it wasn't hard to set it up to have both the volume faders and mutes work on the OBS sources I want it to but for the life of me I can't get this plug in, or any other, to let me change the highs, mids or lows with the dials. I can enable it and disable it easy but nothing seems to want to let me change the values with the dials.

Any thoughts or links would be greatly appreciated.

 

[AaronD]

The "Get current settings" button on this action gives you the format to use:

Maybe you can put your desired settings into some Variables, and then use those Variables as part of the settings string?
(multiple actions to build up what you want, not a single one that "just does it")

It would indeed have to be set up like suggested by @AaronD.

You will need three variables.
One to control the "high", one to control the "mid", and a final one to control the "low" setting of the filter.
When those variables change values you want to change the corresponding filter setting.
This can be achieved by setting up three macros similar to the following example done for the "mid" value:

After those three macros are set up you need to create the macros which assign values to the variables when specified MIDI messages are received.
For this you will have to use the "Midi" condition.
You can use the "listen" button to check which control of your MIDI device maps to which values.
In the example below I am using the "Volume" slider of my virtual MIDI device.
This slider results in MIDI messages of type "Control Change" on channel 1 with "value(1)" being fixed to 7 and "value(2)" being the value we want to use to control the filter setting.

I also added a step to modify the the value received by subtracting -20 from it.
This was done as the 3 band EQ expects the input range of -20 to +20, but the MIDI device I am using in this example is sending values starting at 0.
The exact settings will very likely differ from my example.

Note that you should uncheck the "Perform actions only on condition change" option for the macros receiving the midi messages to ensure that all received messages result in a variable change.

I would also recommend to configure to a very low condition check interval value on the General tab as Midi messages might arrive quite quickly and you want the delay before those messages are processed to be as low as possible.

You can check that the value of the variable is updated properly on the variable tab.

The filter settings should be updated accordingly as well.
Note that OBS does not update the values shown in the filter settings dialog when the values are changed programmatically.
So, it is probably easiest to "listen" to the source by adding an audio monitor to it to verify that everything works.

Hope the example was somewhat understandable and helped! :)

Hello!

I am running a distributed setup and would be curious if it's possible to trigger exection of a Macro on a remote instance of OBS, e.g. after ReplayBufferSave

Hello!

Yes that should be possible using the Websocket condition / action type.
One OBS instance will listen for a given message and then perform an action.

While the other OBS instance will send a message when the replay buffer was saved.

Let me know if you have any questions! :)

 

[AaronD]

Hello!

@Warmuptill is accurate - that is the way to do it - but not quite complete. There's a server/client relationship here. Depending on which you've decided to be which, you can both Send and Receive both Requests and Events. The only difference that I see is which one needs to have the server set up in OBS itself (not Adv. SS), and which one needs to connect to that server in Adv. SS before anything works.

Server setup in OBS:

Client setup in Adv. SS:

For two instances of OBS on the same machine, like I use, keep the Address as "localhost". For different machines, you'll need the other machine's IP address there...which can be a source of headaches if it changes. To avoid it changing, you'll need some knowledge of networking, which can get hairy in a hurry, but essentially you want to assign a static IP address to anything that other things connect to like this.

You can tell that machine directly, to always use a specific IP address and not even ask, or you can tell your router to always assign the same one to that machine every time it asks. Either way works; the difference is where the setting is for you to find later, and which device it's in to get wiped out when that device is replaced. Just keep in mind that if two things on the same network end up with the same address, that doesn't work either. So try to avoid that, even by accident.

---

For multiple instances of OBS on the same machine, like I do, it gets interesting in a different way. No IP conflicts - as above, "localhost" works just fine - but there can only be one OBS Websocket server per machine, and only the first instance of OBS can "own" it.

So the choice of which is which becomes fixed by the order that you start all of those instances, and instances 2 and 3 or later can't communicate directly to each other. You can get around that by relaying everything through the first one that you open...as long as that one always *is* the first to open!

Scripting helps a lot with that, so that you only start the script, and the script starts everything in the correct order with the correct delays and settings, and whatever other setup needs to be done.

obs --verbose --unfiltered_log --disable-updater --disable-shutdown-check --multi --studio-mode --profile "$OBS_PROFILE" --collection "$OBS_PROFILE" --startvirtualcam > /dev/null &
PID_MASTER=$!
sleep 10

obs --verbose --unfiltered_log --disable-updater --disable-shutdown-check --multi --studio-mode --profile "Meeting_Slave" --collection "Meeting_Slave" > /dev/null &
PID_SLAVE=$!
sleep 10

This little snippet of a rather large setup script starts two instances of OBS, each with a 10 second delay to let them get sorted, and records the Process ID (PID) of each one so that they can be closed automatically as well. (Send a message from the script to each Process ID, that tells it to shut down gracefully.)

The $NAME's are variables that are set earlier in the script, to make it more flexible, so I can do different things in the meeting, without messing up the others. > /dev/null prevents a ton of clutter in the terminal window (all of that information is in the logfile too, so it's not lost), and the & at the end tells the script to move on immediately and not wait for that command to finish, which it won't until OBS closes.

[L&Mproducer]

I have a scene that contains a bunch of sources (dozens and dozens). Our stream deck has buttons to hide/show each of these. I'm being asked to make an "undo" button that hides the last source shown, then the second last, then the third last, etc. (just like an UNDO button in software does)
I know I could use a data structure to keep a list of scenes that have been SHOWN in the order they have been shown, and when the UNDO button is clicked, it pops the last source off the list and then re-hides it.
The problem is that I don't know how to do this within Advanced Scene Switcher.
I don't want to go making dozens and dozens of conditions for each source, and have to remember to update it each time I change my sources.
Also I see lots of references to indexes (like which index a source is within a scene) but no way to loop through these indexes to do anything super valueable. I feel like I'm missing something.
