* fixed a bug with multi-touch and touch-id-generation on iOS and OS X. (will fix a bug reported by Colin Cochran, without ditching the existing logic)
* removed unnecessary warning-flagss when generating xcode-projects via cmake, will enable the usage of OSG_AGGRESSIVE_WARNING_FLAGS
* added support for 10.9 (OS X)
* new cmake-variable: IPHONE_VERSION_MIN, this will set the deployment-target (previously hard-coded) If you set the IPHONE_VERSION_MIN to something like 7.0 osg gets compiled also for 64bit (amd64)
* cmake defaults now to the clang compiler if IPHONE_VERSION_MIN > 4.2
* cmake now sets some xcode-settings so the compiler uses the c++98-standard (clang defaults to c++11, w/o this I got a lot of linking errors)
* removed include-dir for avfoundation-plugin as not needed on OSX/IOS.
* enhanced the ios-example, will now show multitouch-information on a hud (similar to the osgmultitouch-example), and more importantly, will compile + link out of the box
* small enhancements for the osc-device-plugin (send only one msg for MOVE/DRAG, even if multiple msgs/event is enabled)
* better memory-handling for the zeroconf-plugin
* fixed a possible bug in the rest-http-plugin when receiving mouse-events.
* incorporated a fix from Colin Cochran "forwarded touch events are not transformed into the GL UIView“
"
In CMakeList.txt there is a case sensitivity issue which a fix was posted by Robert Osfield in the users forum.
I also had to rename the files OSXAvFoundationCoreVideoTexture.h and OSXAvFoundationCoreVideoTexture.cpp to OSXAVFoundationCoreVideoTexture.h and OSXAVFoundationCoreVideoTexture.cpp
Finally in OSXAvFoundationCoreVideoTexture.cpp the include OSXAVFoundationVideo.H was updated to OSXAVFoundationVideo.h"
* avfoundation: added support for IOS (CoreVideo-support is still in development, works only for SDK >= 6.0, set IPHONE_SDKVER in cMake accordingly)
* zeroconf: added ZeroConf-device-plugin (Mac/Win only, linux implementation missing) to advertise and discover services via ZeroConf/Bonjour, on windows you'll need the Bonjour SDK from Apple
* osgosc: modified the example to demonstrate the usage of the ZeroConf-plugin (start the example with the command-line-argument --zeroconf)
* SlideShowConstructor: enable/disable CoreVideo via a environment variable (P3D_ENABLE_CORE_VIDEO)
* RestHttp: mouse-motion-events get interpolated
* RestHttp: unhandled http-requests get sent as an user-event to the event-queue, all arguments get attached as user-values to the event
* modified some CMakeModules to work correctly when compiling for IOS
* fixed a compile-error for IOS in GraphicsWindowIOS
* some minor bugfixes"
I fixed some bugs and did some more tests with both of the video-plugins. I integrated CoreVideo with osgPresentation, ImageStream has a new virtual method called createSuitableTexture which returns NULL for default implementations. Specialized implementations like the QTKit-plugin return a CoreVideo-texture. I refactored the code in SlideShowConstructor::createTexturedQuad to use a texture returned from ImageStream::createSuitableTexture.
I did not use osgDB::readObjectFile to get the texture-object, as a lot of image-related code in SlideShowConstructor had to be refactored to use a texture. My changes are minimal and should not break existing code.
There's one minor issue with CoreVideo in general: As the implementation is asynchronous, there might be no texture available, when first showing the video the first frame. I am a bit unsure how to tackle this problem, any input on this is appreciated.
Back to the AVFoundation-plugin: the current implementation does not support CoreVideo as the QTKit-plugin supports it. There's no way to get decoded frames from AVFoundation stored on the GPU, which is kind of sad. I added some support for CoreVideo to transfer decoded frames back to the GPU, but in my testings the performance was worse than using the normal approach using glTexSubImage. This is why I disabled CoreVideo for AVFoundation. You can still request a CoreVideoTexture via readObjectFile, though.
