    Ehh, no. Whenever you are using setPixels and Apply, you are not using openGL calls, it is a generic way to upload data to the graphics card and works on directX and openGL; it is really slow. We use SetPixels and Apply on the Berkelium integration, and the older Awesomium integration and they both suffer from the Achilles heel that is SetPixels() and Apply().

    OpenGL calls would consist of something like:

    Code (csharp):
    1.  
    2. extern "C"
    3. {
    4.     void updateTexture( int nTexId )
    5.     {
    6.         glBindTexture(GL_TEXTURE_2D, nTexId);
    7.         char* bytes = (char*) calloc(50 * 50, 3);
    8.         for( int i = 0 ; i < 50*50*3; i++ )
    9.         {
    10.             bytes[ i ] = 0;
    11.         }
    12.        
    13.         glTexSubImage2D(GL_TEXTURE_2D, 0, GL_RGB, 50, 50, 0,
    14.             GL_RGB, GL_UNSIGNED_BYTE, (GLvoid *)bytes);
    15.        
    16.         free( bytes );
    17.        
    18.     }
    19. }
    20. And this is how I call the function in Unity
    21. Code:
    22. [DllImport ("TestPlugin")]
    23. private static extern void updateTexture( int nTexId );
    24.  
    ...
    Code (csharp):
    1.  
    2. void Update()
    3. {
    4. m_nID = texVideo.GetInstanceID();
    5. Debug.Log( "m_nID: " + m_nID );
    6. updateTexture( m_nID + 1 );
    7. }
    8.

    Actually UnityWebCore can do it in some callback way to create new UnityWebView texture into a new plane.

    It may be an advanced usage:)

    Reissgrant,

    Really appreciate for your sample code!

    I did some benchmark in my dev desktop:

    Using SetPixels and Apply:
    Displaying normal webpage like google.com, the frame rate is 680 fps.
    Playing flash movies, the frame rate is 13 fps.

    Using glTexSubImage2D to access the graphics card directly:
    Displaying normal webpage like google.com, the frame rate is 690 fps.
    Playing flash movies, the frame rate is 280 fps.

    The frame rate significantly improved when playing flash movie!!!!!!!!!
    The only defect of using OpenGL API is that we need to force unity to run in OpenGL mode by adding optioin "-force-opengl".
    In windows platform, D3D may have rendering advantage than OpenGL. That depends on the game developers choice.

    Anyway, we have an alternative way to significantly improve the dynamic image frame rate.

    Thanks Reissgrant a lot for your recommendation!!

    PS: I'd like to correct the usage of texture id:)

    Code (csharp):
    1.  
    2. void Update()
    3. {
    4. m_nID = texVideo.GetNativeTextureID();
    5. Debug.Log( "m_nID: " + m_nID );
    6. updateTexture( m_nID);
    7. }
    8.  
    I will upload the latest version of UnityWebCore in two or three days.
    UnityWebCore will leave the two solutions coexist and developers can choose anyone.

    After adding the support for rendering directly to Graphic memory in OpenGL Mode, the framerate improves significantly when playing flash videos in UnityWebCore.
    Now the framerates are ALMOST THE SAME when playing videos and showing static webpages.(1100 fps)

    See the screenshots of the comparison of framerate in the two situations.
    $flashvideo.JPG
    $googlehome.JPG

    Make sure to read the "Readme-force-opengl.txt" in both of the Demo and Project Package before playing with it.

    Demo package download.

    Project Source package download.

    Hi lubo3d, good work so far.

    I have encountered some problems getting this working, unfortunately.

    I modified the scripts in the package so that it would open a specific address automatically, and removed the control panel GUI. It worked perfectly fine and as expected, in the Unity Editor. However when I made a build, the plane didn't show anything but its white material.

    On a different PC, I downloaded your newest demo to test if that worked. It won't seem to load the HTML nor web pages now, and it simply shows a black plane. I downloaded the newest package and again, it worked in the Unity Editor. I tried making a build from the project and when I tried to play it, I got a BSoD. Upon restarting, I tried to run the build again and got a "Failed to initialize player" error:

    $Failed to initialize error.png

    Any idea what could be causing the problem?

    Thanks

    Actually it's the default behavior in free edition. If you want to customize the behavior, you might want to get a commercial license.

    Hi, SC3

    You might want to read the "Readme-force-opengl.txt" first. Because the newest version of UnityWebCoreDemo added the performance improvement when playing flash video, it could only be run in OpenGL mode. If "force-opengl" is not used, it will only show a black plane.

    So pls run the "UnityWebCoreDemo.bat" instead of the exe file in the Demo package.

    If you made a new build after eliminating the control panel GUI, you need to load one url address manually in the C# script after creating the webview. Or you will see a white plane because no html file is loaded.

    As to the Unity errors you encountered, you can try to delete the previous built files before you building and replacing the old ones. I'm not sure about it, but you can have a try:)

    I just found this thread...sounds really awesome!

    I have one quick question. Is it possible to communicate back and forth between unity and action script in the swf? In other words, if i have an inventory management user interface written in flash is it possible for the flash UI to communicate with unity using ExternalInterface or something to that effect?

    Yes, UnityWebCore support communication between unity and AS in the swf which embedded in the webpage.
    For example, the embeded id of flash is "MyFlash".
    You can call UnityWebCore.CallJS(webviewID, "document['MyFlash'].FuncInAS", arguments) to communicate with flash from Unity.
    Before that you need to export the FuncInAS using ExternalInterface.addCallBack(...).

    Also you can call ExternalInterface.call("UnityWebCore.FuncInUnity", arguments) to communicate with Unity from ActionScript.
    Before that you need to export the FuncInUnity using UnityWebCore.AddJSCallback(...) in C#.


    UnityWebCore also supports loading swf directly! You can type one swf link into the url address box and click Go for a try.
    In that case, the id of flash object is "FlashOject".
    So you can call the function in AS using UnityWebCore.CallJS(webviewID, "document['FlashOject'].FuncInAS", arguments).

    Let us know if you have any question.

    Really nice work.
    Not so much of use to me due to the force ogl which I consider inacceptable, but it is a start upon which there is a chance to see further progress and some pressure towards UT to finally allow access to the DX device and the surface so plugins can finally become meaningfull on the graphical end

    Yes, hope Unity can open the access to DX device directly just like OpenGL. That would significantly improve the performance of some graphic plugins.

    But at least if only normal webpage is used in UnityWebCore. OpenGL is not forced to use. The fps in DX mode is also acceptable.

    Yes, UnityWebCore needs PRO version because it's written in C++ plugin.
    If more developers pay $ for the win version, we can have budget for the OSX version:)

    just tried your system.. really nice!
    I have one question, maybe you can help.
    I have some flv/video files on my drive, which I would like to run from a local html.
    As far as I can see it is not possible to run flv's locally. True? :)
    I am really interested in avoiding playing from a server and wish a local solution.
    Do you have any pointers?

    If you want to play flv or other type of videos either from network or from local, you need a video player while the promising type is flash video player.

    There are many free flash video player or open source ones which are excellent. You can choose one and build to swf file. Put the video file(flv) beside the video player(swf), specify the video file name either in a config file or as the parameter to the swf file.

    Load the flash video player from local for example:
    html/myFlashVideoPlayer.swf?src=myVideo.flv

    You can have the video played in Unity. Just try it and let us know if you have any question.

    SOLUTION to playing local videos through your project:
    1:Installed a WAMPserver from http://www.wampserver.com/en/download.php
    2: made a script in Notepad and afterwards saved it as 'test.html':
    Code (csharp):
    1. <html>
    2. <head>
    3.     <title>Wow! this is a header</title>
    4.    
    5. </head>
    6. <body>
    7.  
    8. <object width="550" height="400">
    9. <param name="movie" value="test.swf">
    10. <embed src="test.swf" width="550" height="400">
    11. </embed>
    12. </object>
    13.  
    14. </body>
    15. </html>
    16.  
    3: Made a folder with the script(now a html file), the test.swf file and named it 'videotest'
    4:Make sure your server is running (You dont need to do anything setting it up, use default settings ).
    5: copy your 'videotest' folder into the 'www' folder under your WAMP directory (usually C:wamp/www)

    6: Play the WebCore scene in Unity and in adress fill in: C:\wamp\www\videotest\test.html
    alternatively 'http://localhost/videotest/test.html'
    This has solved my problems in NOT storing huge video files online and NOT pre-load huge movietextures when running a scene in Unity.
    Thnx for your tool, and hope this solution adds to its use.

    Questions for the developer: I want to load different preadressed instances of the plane when interaction with different buttons has been performed? Same as spawning a movie texture, but with your system :)

    @lubo3d: In order for me to use this, I need to return a value from Unity to Flash, as well as get a return from Flash to Unity, via the External Interface. Can this be done (or added) in UnityWebCore?

    Also, I have a SWF I use to test my existing External Interface API that is basically a textbox where you type a function name and button that executes the function. I can click in the textbox, highlight text in the textbox, delete text from the textbox using backspace, but I can't type into the textbox. Has anyone else seen this behavior?

    I noticed one bug and have a solution that I would like to share with others. My project has a bunch of render textures and cameras. In OpenGL mode the plugin would overwrite one of the other render textures (in addition to updating the correct render texture). You would see the webpage in two places rather than just the intended object. It seemed to be overwriting whatever was the active camera at the time, but only if the active camera is pointing to a render texture.

    This bug is not visible in the editor... only visible in the built versions of the game in OpenGL mode.

    The solution I have to an additional "GarbageRenderTexture" that is never shown on screen and activate it before you update the UnityWebCore object.

    Put this GarbageRenderTexture.cs in the plugins folder and call it before you render into OpenGL textures using a plugin/getnativeid

    This happens in the update function in the UnityWebView.cs

    Code (csharp):
    1.  
    2.         GarbageRenderTexture.absorbBug();   // bug fix code goes right before the texture is updated
    3.         UnityWebCore.Update();  // original code
    4.  

    P.S. This fixes similar bugs in other plugins for example the QuickTime plugin or procedural texture synthesis plugins.

    Here, I'd like to share the easiest way playing local flv video files , just like reading piece of file.
    Fill "html/videoplayer.swf" into "File" editbox and click "Load". If you want to play your own flv file, just change the config in vcastr.xml.

    The AS3 source of videoplayer.swf could be downloaded from http://vcastr.googlecode.com/svn/trunk/vcastr3/release/src.zip


    This sample is included in the latest demo package.

    Retronamic,

    UnityWebCore depends on external flash player plugin(npswf32.dll). Make sure that the flash player you are using is the latest release version.
    If you still encounter the crash problem, would you please post the screenshot or some steps that we can reproduce?

    Thanks.

    Yes, UnityWebCore introduces Webkit engine into Unity. WebKit is developed by native C++. So there may be less possiblity to port to Unity webplayer:(

    Webplayer can access html or flash easily via Unity interaction with web browser. Although it's not embedded into Unity directly, it's an alternative way.

    For the security reason, webplayer doesn't support access to dll written in native C++. So maybe there won't any chance for UnityWebCore supporting webplayer unless Unity webplayer integrates this part.

    iphone/ipad/android?

    How would those work.

    How does this project relate to Awesomium? and don't they want 999 dollars for their plug-in?
