GPU and GLSL run basically the same way.

Don't use any vid-CPU anything. You may want to use the 'Chop Pixels' actor to cut up your 4K grid.

Thanks, DusX , Michel  for your comments!

As i understand, NVidia cards more preferable. 

Hi,

someone have solved this:

2015-10-31: Reports indicate EasyCapViewer doesn't work on OS X El Capitan?

I need to use my old GOpro camera live with Isadora but with my Mac (MacBook Pro Retina, 15", 2015 - 2,8 GHz Intel Core i7 - 16 GB DDR3 a 1600 MHz - AMD Radeon R9 M370X 2048 MB) EasyCAP do not work!

Thank you

I would likely use two Matrox Triple heads to go.

each can easily handle 3x 640x480 outputs. You could probably even use a Matrox Dual head to go, with 2 triple heads attached if you only have one Display port out. The total resolution you are after is pretty low, so this shouldn't be to much of a strain. You are looking at 3840 width (640x6), and assuming mini display port, can handle this if running version 1.2 " the Mini DisplayPort can drive display devices with resolutions up to 2560×1600 ([WQXGA](https://en.wikipedia.org/wiki/WQXGA#WQXGA_.281600p.29 "WQXGA")) in its DisplayPort 1.1a implementation, and 4096x2160 ([4K](https://en.wikipedia.org/wiki/4K_resolution "4K resolution")) in its DisplayPort 1.2 implementation. "

Maybe submit it as a bug report @jrhooker?

There is an online test stream: will PM you the details, and you'll get to peer into my living room...

May I ask how this is related to Isadora?

Not meaning to sound rude. We are all friendly here but this looks like spam. 

Thank you @artoo but which download you mean ?
I consider to buy 2 Logitech PTZ Pro camera. They have a great image quality and can pan&tilt with a 10x zoom. I will search a solution to control the 2 camera "in live"
Thank you

@mark_m

I'll let you know if I get anything ready to share as well... It won't be in the next couple of days either 😉

Thanks Dusx, I will try that nice idea!

@craigw,

I once had a similar issue with my USB license reverting to Demo Mode over and over. After running up to the booth to unplug and replug the USB for the third time or so, I noticed the computer was very warm and that Isadora USB was also becoming very warm. I then plugged an external USB hub into the computer and plugged my USB into the hub, rather than plugging it into the computer directly. After that, I did not have the issue again. I'm still convinced it was heat-related, and now I always plug in my USB into any computer I'm using via an external USB hub. Do you have a external USB hub kicking around? Couldn't hurt to try it, right? Best,

Woland

@Michel
That looks rather cool.. too late for me though.  🙂

Hey Mark, sorry, I didn't get back to you, been very busy with Vacation Bible School.. I seem to have it working, it required changing the audio to APPLE..

Thank you,
I'll start with that to capture live video.

@Armando,

Hello thanks for that. I used to do the same with 2 BM thunderbolt mini rec. My doubt was coming from resellers who said it doesn't work with Mac ! BM support just confirmed it was a mistake but too late because in-between I had to buy one. I chose the BM decklink duo 2 in a akitio thunderbolt 2 to pcie. have a good work.

Thanks to Mark and everyone for suggestions. I have now completed the project using a Mac Pro with 4 x 20K lumen video projectors (1920x1200 res) and a control monitor. The projectors and monitor were connected through five IOGear TB to HDMI adapters.

The video sources were two ProRes 4K movies (3920 x 2160), which were mixed together in real time with continuous color and luminance adjustments, and then split into 4 x 1920 x 1200 quarters, all running at 24 fps with edge blending and izzymapping. You can see video documentation and photos here:

Hi Fred,

Yes, we used the aktio and it worked fine. Best Mehdi

thanks for sharing!

yes: no thunderbolt, and Windows

@gapworks I had some "improvements" with the situation: If I use the incremental version of the position it works fine, even from Isadora, and the commandes appears to be in the good order as in:  "GET /service/galileo/position?pan=" **P1** "&tilt=" **P2** " HTTP/1.1\r\nHost: 192.168.0.28\r\n\r\n" But still no change for the absolute positioning (which is the feature I would like to use...) So to me I would really think there's something with the airbeam version or the Motrr SDK version they are using I have  Airbeam v 2.1.4 (build5) Since it seems to work properly for you @Marci , I'm curious to know which version you're using
