@juriaan Done as requested.

Hi all,

Currently working on a video player - with very simple actions to edite live the video - I'm encountering a problem with the movie player on computer on Monterey (12.6 & 12.5.1).

Sending a new position (for the movie, and start and length), movie player did'nt react proprely, The video doesn't go to the right position on the video (mov/HAP). Movie player on optimize in interaction - and isadora tell me that the pb engine is on AV. Do you know if it is a way to fix that?

On Mojave (10.14.4) - the same patch, with pb engine on QT - is working perfectly.

Thanks! Flo

This looks to me like Isadora had a problem reading the Font and has subbed in a default font. Maybe try uninstalling the font and re-installing it.
I don't have this font so I can't test it specifically, but I have hundreds of fonts and haven't had problems.

@dusx @beyondpicture 

apologies for the misinformation 

@emullis

It's tricky to remember because this feature allowing the use of external .js files is very new so most of us (including me) are not used to having to think about moving a .js file along with an Isadora file. At least, that's the reason as I see it (and it happens to me quite a bit) 😅

@jacob1970

Just curious: Why don't you use the „Timed Trigger" actor:

Thanks @Woland for that explanation of how to get the output to mutate (?!) to the right sort of data. That's really useful, and thanks also for the javascript explanation. Also invaluable in the current circumstances with the ol' clock ticking.
Thanks @jfg for the user actor! Very useful!

When I've got this show up and running I'll make the captions file available to all properly commented.
Once set up it's a really fast way to create a load of captions very quickly which auto-selects fonts and colours for a number of different 'speakers'.

@knowtheatre

When you transition scenes, you possibly have audio playing to the same channels from multiple players. My guess is that you have some audio configuration on your system that doesn't like this change of audio source/routing/mixing.
Can you please take screen captures of your Audio setup in macOS? It doesn't sound like a feedback loop but seems like it must be similar.

@noam

As @Juriaan asked, we would need more details before we can offer too much help.

I would start by saying that this may be an issue with the device not being detected correctly by the computer. I would recommend unplugging the device, and rebooting your system. Once fully running again, reattach the device and let the system configure itself. Then open Isadora and see if the device/driver will connect as expected.

@dusx

I'd like to add, this is a system setting, done in the monitor settings (color managment) of the OS. Every device does offer a specific color range, it can show. So it may be able to show more or les colors or have the same amount of possible colors (eg. 16+ milions), but differences in the color shift. You need to match the color profile to the displays/projectors profile (some standards are sRGB, Rec. 709, DCI P3 e.g., or even device specific). This applies to print as well. This is easier on MacOS then on Windows, as MacOS already offers some profiles. Just switch between them and you'll immediately see the difference.
find some details here.

One other setup is a quiet unknown: Full vs. limited RGB. RGB values on full are 0 - 255 for each color (Red, Green, Blue). Limited only use 16 - 235. Full is used by PC and grafic setup, while limited is most time for Video. 
Here is an complete article for it.
This setting has to be consistent for the whole chain of devices, from Input (if some camera capturing is done) over the GPU output to the display device or needs to be converted properly.
If not, results are crushed shadows and flat highlights or gray blacks and whites.

Thanks DusX

So here are some spec:

Seems quite Ok on:
Mac Book Pro - 13 inch 2017 Intel Core I7 Mojave 10.14 - Isadora 3.2.6

Many cracks on:

Mac Book Pro - 13 inch 2020 Intel Core I5 Monterey 12.5.1 - Isadora 3.2.6

Mac Mini M2 - Ventura 13.2.1 - Isadora 3.2.6

We only use the integrated speakers

@woland Thanks so much! Yes this all makes total sense. I may look into these solutions or just put up with it as you say. As my PhD is around temporality it may even be good that there is a kind of delay or gap between the hand and the onset of the line ☺

I just sorted this out with @grimvisions

For anyone who reads this because they're experiencing a similar problem, the solution was to go to Isadora > Isadora Preferences > General tab > Framerate / Tasks > Display Refresh and change it from "Scaled" to either "Off" or "Full". 

Off" gave us 30fps with a target framerate of 30fps in Isadora Preferences."Full" went significantly above 30fps (fluctuated between ~40 and 75fps) with a target framerate of 30fps in Isadora Preferences.

@houssem

I have tested on my Mac and I suspect it could come from the connection with the projectors, because if I delete the user actor "shutter" right at the beginning, the patch doesn't hang anymore. Maybe the "Send PJLink" actor reacts badly when it has no connection with projectors, in the case you tested without projectors, which is my case because I have no such projectors.

I have made a patch with the 3 first scene and a global value actor to switch a gate for the shutter actor and if you set it to off the patch doesn't crash/hang. Perhaps you have to change something in the shutter actor but I cannot say what since I haven't any experience with this actor.

@dusx
Thank you so much for your answer, I've been trying and testing some things and your suggestion of testing Isadora to Isadora was very useful. there seems to be an ndi compatibility issue between touchdesigner and Isadora or something. right now I'm using syphon on the Touch macbook to get the visuals into Isadora and using ndi to send it to the other computer.

So syphon Touch > Isadora gives smoother results than using NDI it seems.

Hope this helps others as well who run into this problem

@steinster said:

some potential work-arounds would be nice

You can edit GLSL code on ShaderToy and then copy it into Isadora or a txt file: https://www.shadertoy.com/view/4llSDSYou can save text files in the folder that's opened by going to Help > Open Plugin Folder > TroikaTronix GLSL Shaders and they'll show up as GLSL Shaders in the GLSL shader actor bin the next time you launch Isadora. (So if you add text files to this location, quit Isadora, then re-launch it, then the GLSL Shaders will appear in Isadora.)

Hi Woland!

Thank you so much for your help. Now this is even weirder. At first, when it didn't work proparly, my settings looked the same like your screen captures. 

I than changed the Nvidia settings like in one of your links and now it looks like this..but it works.. the video is now displayed at the right screen..haha

so it's weird...but it works!!

Thanks a lot!!

best wishes,

Maartje

Hello@dusx!

The original driver version of the RX560 card on the AMD website It's 23.3.1, didn't work! It worked with another version of the recent board RX580 23.3.2.

I just had a similar problem last week while trying to send NDI and OSC to and from a powerful Windows show computer that belongs to a university that has very strict network and computer security protocols. I never did figure out what setting on their computer was preventing it, but when I hooked up two non-university computers to a network switch I was able to send NDI and OSC back and forth without issue. I suspect it was a firewall problem, but nobody around had sufficient security credentials to do anything to the firewall's policies regarding Isadora on the university computer. So maybe check your firewall settings on both computers? Also, as a test, I'd hook up a third computer to your network switch and see if it can send and receive NDI to and from your original two computers. This test might help you identify which one of them is the problem.
