Confusion: the last major release has only source code

[newemka]

Hello, usually your releases have 3 assets, one zip file of the add-on and two source files. Is this an oversight?

[maybites]

no, its intentional. With the recent renaming of the repo it is actually possible to download the addon just in the standard way. https://github.com/maybites/blender-texture-sharing/archive/refs/heads/master.zip

If this causes a problem, pease let me know.

[newemka]

No luck for me. I'm on Windows 10, Blender 4.1

When I press the button to install the SpoutGL, I get this message: Cannot install package : SpoutGL

For NDI, when I try to disable and enable the add-on, I get this error:

Traceback (most recent call last): File "C:\Program Files\Blender Foundation\Blender 4.1\4.1\scripts\modules\addon_utils.py", line 444, in enable mod.register() File "C:\Users\newem\AppData\Roaming\Blender Foundation\Blender\4.1\scripts\addons\blender-texture-sharing-master__init__.py", line 36, in register pip_importer.register() File "C:\Users\newem\AppData\Roaming\Blender Foundation\Blender\4.1\scripts\addons\blender-texture-sharing-master\pip_importer.py", line 346, in register register_class(cls) ValueError: register_class(...): already registered as a subclass 'Pip_Update_package'

After restarting Blender I can select Streaming Type NDI but once Share texture is activated I don't see it in my other applications. I've tested with NDI studio monitor and Tooll3

1. Can you provide the full log in the windows console for the SpoutGL error?
2. I have seen this error, too. I don't know yet what causes it. I will look at it comming monday. I assume you test with v6.0.3?

the whole thing is tricky, since I have the to make the addon running even if the core libraries aren't installed. it requires some architectural gymnastics that just got more complicated by implementing NDI.

Any steps and detailed errormessages you can reliably reproduce would be helpfull.

[newemka]

Sure, here are the messages I can gather in Blender Console windows 1. SpoutGL install

2. (when I try to disable and re-enable TextureSharing)

[maybites]

are you sure you have the latest version?

[maybites]

It should be fixed now with V6.0.4.

Please let me know if it works for you.

[newemka]

Hello, I've just downloaded it again.

Version still shows 6.0.0

SpoutGL install: success It's woking fine with Spout Receiver and Tooll3 (Flip outgoing texture needs to be activated)

Ndi: I get the image in Ndi Studio Monitor and Tooll3 (the image is flipped) Flip outgoing texture has no effect

Activating Show Preview breaks the texture sharing for spout and ndi

[newemka]

Update: About NDI color management

in order to get the righ colors I had to swap the Red and Blue channels

[maybites]

NDI colormanagement and preview is fixed. I don't know how to do the flipping, though

it has to happen somewhere here. probably a nifty numpy function that transforms the buffer array...

[newemka]

Despite my efforts to look at the code, I only managed to break it.

[newemka]

I noticed here that the version of NDIlib is 5.1.1.1 While on https://pypi.org/project/ndi-python/ the last version is 5.1.1.5

[maybites]

the reason I have to install this NDI wrapper manually is because 5.1.1.1 is the last working pip version but it only supports up to python 3.10. The developer doesn't respond anymore and doesen't seem to be interested to update the pip repo. So manual it is, resp. self compilation in case of linux. In a few days I will be able to compile the OSX version too.
