MultiFunPlayer v1.33.5 - Multi-axis funscript player with SLR ＆ FapTap support

Yoooi · June 6, 2025, 3:01pm

Oh, yea that one was my fault, it was fixed in v1.33.0. Basically MFP tried to grab a handle to the potplayer window before it was shown. So it was reading data from invalid window.
Btw you don’t need start a video before connecting, just make sure the window is open.

Hello! I have a question: I would like to make the playback behavior of scripts in MFP work like that of ScriptPlayer. Sorry if this is unclear. When I play a script in MFP, if it’s a continuous script running from 0 to 99, it moves like 0, 10, 20… so I’m not very used to the smoothing function. I’d like to turn off this smoothing function—could you tell me how to do that?

Also, is there anything I need to configure in MFP to make the script playback behave like it does in ScriptPlayer?

MFP v.1.33.0

Yoooi · June 7, 2025, 7:55pm

Do you mean smoothing like when you play/pause the video the device smoothly ramps up the motion? Or do you mean smoothing as in how MFP sends multiple small steps instead of one long step from 0 to 99?

To make MFP behave like ScriptPlayer the most you would have to change from FixedUpdate to PooledUpdate via the clock button in the bottom right. You can only do that while your serial/udp output is disconnected.

But note that PooledUpdate is meant for devices that can’t handle the amount of updates and it basically one supports script playback, most of MFP features will be ignored. So if you have OSR/SSR1 I would advice against it unless you have some specific issue with FixedUpdate.

qopqopqopp1 · June 7, 2025, 8:07pm

Both types of smoothing! One that makes the device start moving smoothly when the video is played/paused, and one that sends multiple small steps instead of a long step from 0 to 99!

qopqopqopp1 · June 7, 2025, 8:14pm

I’m sorry to ask again, but is it okay to leave these settings as they are without changing anything?

Yoooi · June 7, 2025, 8:33pm

Then switch to PooledUpdate.

If you switch to PooledUpdate only invert script and speed limit work from those settings, others are ignored.

Running 1.31.3:
The MFP UI states it connects to Plex HTPC, then immediately disconnects. Behavior (and log) repeats with Auto-connect on.

This feels slightly different than most of the plex errors I’ve seen in the thread; MFP is definitely able to at least say it’s connected to the Plex HTPC client. I haven’t been able to track down a ‘listen on this port’ option in plex, but totally possible I’ve missed it.

Not sure if any of that’s relevant, but that url is neato.

MFP log (note: handy is disconnected during this log dump, but same issue occurred when handy was connected)
(In the event that it matters, hitting the same issue with the self-contained 1.31.3 as well)

qopqopqopp1 · June 7, 2025, 9:10pm

One last question:
When the script is stopped, is there a setting that makes the hole return to the base position during pause?

In ScriptPlayer, this would be the “Enable Auto Homing” option.

Yoooi · June 7, 2025, 9:37pm

@superheadon
For plex you need a server. MFP connects to the server not the clients.
Also X-Plex-Token is a parameter so it needs to be at the end of the url, so either ?X-Plex-Token=... or &X-Plex-Token=...

Yes there is auto-home, its enabled by default so you must have disabled it.

superheadon · June 7, 2025, 10:13pm

Plex Server’s running without issues; I can connect on http://127.0.0.1:32400 , the plex app, and the Plex HTPC app.

Plex HTPC is the only version that I can get to show up for Plex in MFP:

Will the Plex server logs from around the same time as the error in the MFP logs help anything?

Yoooi · June 7, 2025, 10:37pm

Yea trace logs from start to exception from plex source could help.
What plex server version do you use?

Is there a way to fill the start gaps of a video? when the funscript has no action from the start of the video the software skips directly to the start of the funscript

lucky · June 8, 2025, 1:55pm

Hi, I updated the plugin according to your recommendations, I hope I didn’t make any mistakes. I added some functions too. However, I would like to put the same slider system that you put in the output range to the random threshold for the merged ones but I can’t do it

Yoooi · June 8, 2025, 2:25pm

I updated just in case and for me Plex with MFP works fine with iOS plexamp and Plex HTPC. For some reason it seems like they removed the ability to control the iOS app and Plex for Windows (Supported Plex Companion Apps | Plex Support).
So it seems like an issue on your end.

Yes, disable skip to script start and setup motion provider on L0:

You can of course use other motion provider if you want.

You need to put common properties like UpdateInterval, RandomThresholdMin, RandomThresholdMax, Selected etc. to a AxisSettings class, then expose Dictionary<DeviceAxis, AxisSettings> from your plugin class and bind it in view with for example ItemsControl.
Here is view part in MFP: MultiFunPlayer/Source/MultiFunPlayer/OutputTarget/Views/SerialOutputTarget.xaml at f485e7a4eb996869c056bf56f365575c934a08ae · Yoooi0/MultiFunPlayer · GitHub
In plugin you can simply do AxisSettings = DeviceAxis.All.ToDictionary(a => a, _ => new AxisSettings())); to initialize the dictionary.
This way your plugin will handle all axes and you won’t have to use DeviceAxis.Parse, and you wont have so many properties.

For the SetAxisValue you are still using 0.1 duration, I think you should use the interval instead.
You could try adding invokeDirectly: true as the last parameter to the InvokeAction for "Axis::Value::Set" to gain some performance.
Also I don’t know if having tasks per axis is necessary, seems a little bit over complicated.

GoNikky · June 13, 2025, 10:24pm

Hi Yoooi,
I recently discovered MFP and gotta say it’s truly a great piece of software! I wanted to ask though, does MFP also support MQTT? If not, would it be possible to add this? I would love to be able to hook it up to my Shelly S smart plugs, to control mains powered toys.

Yoooi · June 13, 2025, 10:46pm

Its possible via a custom plugin. I can’t add direct support for everything to MFP, so everything thats outside of “standard” setup has to be done via plugins.
