ah @woland, thanks for your reply, my mistake... i didn't realise Rosetta is only required for the install. Have enabled Rosetta 2, installed Isadora 3.2.6  and yes indeed it's showing as "universal".

Will report back performance findings shortly.

Rgds, Mr J

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.

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.

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

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,

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.

@autmist

I sent you a message on the forum messaging system asking a question. Depending on what your answer is, I may be able to get your students up and running again right away.

Damn - just changed all commas to points and it works.

 I'll file this as a potential bug.

Glad it's working for you now.

@elena

Lol, we just edit the title of the post to add “[SOLVED]” at the beginning.

I’ve done this for you. Have a lovely day :)

I've been having repeted issues with Isadora not being able to play a footage all the way to position 100. Do you have any idea why this might be?

 Unfortunately I don't know enough about the nuts and bolts under the hood of the playback engine to give you an answer about this.

I really appreciate the perspective for longer form media

It's not just for longer form media though. If I had your six-frame video and I wanted to loop it for 5 minutes, I'd make a 10-minute long movie file in editing software that's just those six frames over and over. If you never get to the end of the file because you make the file longer than the duration for which you need it to loop, you don't need to worry about anything to do with seamless looping nor what happens at the very end of the video file.

i just discovered that 'nan' generally means 'Not a Number'

@dusx I did now, 

thanks for your support in this 

@woland Ah thanks both - range makes sense! Constraining the output range on the Program Change Watcher fixes it, as does your suggestion of an Absolute Value actor in between.

Thank you! Bug in my head, in this case :)

@semmeth

Open a support ticket and one of us will get into this with you.

However, a great first step is to see if there is an updated video driver available for your GPU (often an update is needed after a windows update)

I have the same problem as @craigalfredson. If my MacBookPro M1 is between the two external screen, it works well. If I put the two external screen together on the right or on the left side of the MacBookPro I get in fullscreen mode the picture only on the first screen. 

The first screen is connected with an adaptor. The second screen direct with the HDMI output of the computer.

Mark… In that this seems to be a very regularly requested option for Izzy, is there anyway that for future updates, this could be a regular part of the media player to have time as one of the output selections?

I use this very regularly with my work, and this would be a great update inclusion.

@mrkrstoffa

How did things go?
