Did anyone get TexturePlugin demo to work on Windows?

I guess the title says it all. We built a custom plugin on an OSX side but the thing failed to work on Windows when the project was built for Windows platform. Upon further investigation we found out that the original TexturePlugin demo available from the Unity3d.com does not work on Windows either (it has the Windows dll included and when the project is built for Windows, it fails to make any texture whatsoever leaving cube black).

Any ideas?

 

Thanks for the info. However, OpenGL seems quite inefficient on XP side. Hence, I was hoping to harness D3D for this purpose (now that I know I need to use it to get good performance). That being said, unlike GetInstanceID() which returns int value of the current texture within Unity and can be passed into a plugin, for D3D, I was unable to locate a method that would expose underlying D3D plugin to the referenced texture. Am I missing something or does the current version of Unity lack such method? Or, (since I am not very experienced with D3D) am I missing some kind of a D3D method that would allow me to use resulting GetInstanceID() int value to reference the texture?

For what it's worth, having a working D3D implementation of the Texture Plugin demo would be most helpful.

 

Hi,
I also found out that the texture or quicktime plugin is indeed not working under Windows / Directx Environment. I would write a directx implementation, but there is no documentation at all regarding directx/plugins. Is it actually possible to write a plugin which supports d3d ? can I use the textureID supplied from opengl? glBindTexture is supposed to replaced with g_d3d_device->SetTexture(0,g_texture);
Where do I get the d3ddevice? Can someone from Unity (Aras?) make up a small hint how to change the texture plugin to work with directx ?

Hi Aras,
thanks a lot for your help. I will try and get the quicktime plugin to work under windows. But is it possible to write a plugin which uses directx / d3d calls? Is the conversion from opengl to directx done in realtime or while compiling? Can you tell us more about the upcoming Unity 2.1 ?

One thing I wanted to achieve is render the current scene to a broadcast device like a decklink board or write an AVI File. With your method, could I get access to the renderbuffer as well ?

Hi Aras,
I made the quicktime plugin work both platforms and with alpha channel, but since I have to convert from bytes to floats its very slow (ARGB 1024x512 around 5 fps). Do you hav an idea how to speedup the whole process ? Can I access opengl textures while running under windows in directx ?
regards

Hi Aras,

it seems that it was a problem with the codec. We tried png, but it is decoding too slow, like jpeg2000. We tried the Animation codec, but its almost uncompressed and runs only smooth off a raid array. Can you suggest a quicktime codec which compresses and has alpha as well ?

We recently ran in to this cross-platform problem with the quicktime plugin. We don't want to force opengl mode on Windows for performance reasons.

Is it possible to get your code for this? Maybe the quicktime plugin page on the wiki http://www.unifycommunity.com/wiki/index.php?title=QTPlayback
would be a good place to put it.

 

I took a quick look at the API and it looks like GetNativeTextureID is still only valid for OpenGL. Is there still no way to access the underlying GPU data?

I have a client that needs a 1080P live video stream (1920×1080 pixels) displayed in Unity. I'm going to try the approach outlined above for working generically with textures, but this seems really inefficient.

Do you have any other suggestions that might work better?
