The API has changed quite a bit, so lots of changes had to be made in the osg readerwriter. The preious version of the FBX SDK (2013.3) already deprecated a lot of the names and functions. The code I submit now still compiles against 2013.3 (possibly needs a #define FBX_NEW_API). Not sure if that's useful, but it might ease the transition."
Header update
FindFFmpeg.cmake has been changed in order to support the new header include format for FFmpeg. In the 1.0 release, a new file had been added with the name “time.h” in the avutil library. The previous method of adding includes caused conflicts with the ANSI C “time.h” file. Now the include directive will only use the main include folder. All files using the old include format have been updated to reflect the change.
Added __STDC_CONSTANT_MACROS define to CMakeLists.txt
Since there is no guarantee that FFmpegHeaders.hpp will be included before stdint.h is included, the define has been moved from FFmpegHeaders.hpp to be part of the CMakeLists.txt for the FFmpeg plugin. This will allow the define to work on all compilers regardless of include order.
Replaced AVFormatParameters with AVDictionary
AVFormatParameters is no longer supported in FFmpeg and has been replaced with a key/value map of strings for each setting. FFmpegParameters and FFmpegDecoder has been updated to reflect this.
Replaced av_open_input_file with avformat_open_input
FFmpeg now opens files using avformat_open_input. Since the av_open_input_file method is deprecated, the FFmpegDecoder class has been updated to reflect this change.
Added custom AVIOContext field to options
Since some formats and inputs may not be supported by FFmpeg, I have added a new parameter that allows a user to allocate their own AVIOContext. This class will allow for creating a read, seek, and write callback if they desire.
Checking for start_time validity
It is possible for some file formats to not provide a start_time to FFmpeg. This would cause stuttering in the video since the clocks class would be incorrect.
Removed findVideoStream and findAudioStream
The new FFmpeg release already has a function that will find the best audio and video stream. The code has been replaced with this function.
Updated error reporting
Some functions would not log an error when opening a file or modifying a file failed. New logs have been added as well as a function to convert error numbers to their string descriptions.
decode_video has been replaced
The old decode_video function would remove extra data that some decoders use in order to properly decode a packet. Now av_codec_decode_video2 has replaced that function.
Picture format changed from RGBA32 to RGB24
Since most video will not contain an alpha channel, using a 24 bit texture will use less memory."
* 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"

image data. Unlike other formats, GTA also allows very good compression
ratios for floating point data. The compression method can be selected
with the COMPRESSION option of the plugin.

VS2010 is not marked as MSVC100 but MSVC10. And CMake defines
MSVC_VERSION instead of MSVC_VER to indicate the version number. The

of atomic implementatition, making it possible to force the use of Mutex for OpenThreads::Atomic,
and as a consequence for use of Mutex for Referenced::ref/unref() counting.
"There is a redundant cmake code at the end of osgViewer cmake script. The install command is issued in SETUP_LIBRARY macro."
"I spotted this when i tried a make install on the android port :) I saw some weird copy commands of osgViewer headers.
I managed to get all osg headers copied to cmake_install_prefix/include upon make install, but i can't (yet) get the libraries to be copied to cmake_install_prefix/lib (see attached files)"
I also modified the CMake and pkgconfig files to append the _POSTFIX extenstion based on the CMAKE_BUILD_TYPE.
Additionally I fixed packaging/ld.so.conf.d/openscenegraph.conf.in to add a '/' betweeen the arguments since the CMAKE_INSTALL_PREFIX can't end with a '/'.

This feature has been introduced to cmake in 2.8.3, on older versions it should be ignored silently. I tested on Visual Studio 2008 with cmake 2.8.3 and 2.8.4.

This needs few changes:
activate on global cmakelist.txt:
[code]set_property(GLOBAL PROPERTY USE_FOLDERS On)[/code]
set appropriate folder names for project type in osgMacroUtils.cmake:

SETUP_EXE, in order to have a unique entry point to build the

I have attached a patch, against the trunk from 13:30 today, which consists of the following:
1. CMakeModules/FindOpenEXR.cmake: Look for libIlmThread and libIex as well. 2. src/osgPlugins/CMakeList.txt: Only include the exr subdirectory if both the OpenEXR and zip libraries were found. 3. src/osgPlugins/exr/CMakeLists.txt: Add ZIP_LIBRARY to TARGET_EXTERNAL_LIBRARIES."
I modified the OsgCPackConfig.cmake.in and OsgCPack.cmake files to expose access to select the package generator mechanism through cmake CPACK_GENERATOR option. The user can specify the type of package generator (i.e. rpms. deb, NSIS, tar, zip, etc) that they would like to use from the CPack supported packages/installation methods.
I also changed the CPACK_PACKAGE_FILE_NAME to use OSG_PACKAGE_FILE_NAME which contains the name of each component so all of the component packages can be generated without renaming the files.
This should make it even easier to create distribution packages for the various linux, windows and mac distribution methods supported by CPack."
changes from the DirectInput devices and add events to the event
queue. I've tested with the keyboard and joystick supports. Because of
only having a very old 6-button gamepad, I can't do more experiments.
Hope this will bring more ideas to those who face similar problems,
especially simulation game designers. :)
I didn't map all DirectInput key values to GUIEventAdapter key
symbols. Users may add more in the buildKeyMap() function freely. The
mouse handling operations are also ignored, but will be easily
improved in the same way of creating keyboard and joystick devices.
Please add a line:
FIND_PACKAGE(DirectInput)
in the CMakeLists of root directory. And in the examples/CMakeLists.txt:
IF(DIRECTINPUT_FOUND)
ADD_SUBDIRECTORY(osgdirectinput)
ENDIF(DIRECTINPUT_FOUND)
DirectX SDK 2009 is used here, but an older version like DX8 should
also work in my opinion.

But I also found rev. 11354 (from Wang Rui) added a change in OsgMacroUtils which adresses a similar issue: Wang told the "../../bin" prefix wasn't working. However I think the fix isn't correct because it checks the MSVC version instead of the CMake version. Here is my fix, against latest trunk (root CMakeLists.txt, and CMakeModules/OsgMacroUtils.cmake).
Tests I made:
| Unix Makefiles | MSVC 9 | MSVC 10 x64
---------------------------------------------------
CMake 2.4 | | OK | N/A
CMake 2.6.4 | | OK | N/A
CMake 2.8.0 | | OK | broken support?
CMake 2.8.2 | | OK | OK

changed extensions from .c to .cpp and got compiling as C files as part of the osg core library.
Updated and cleaned up the rest of the OSG to use the new internal GLU.
"changed the CmakeFiles for OpenThreads and the
osg-frameworks, so they are versioned by OPENSCENEGRAPH_SOVERSION. "
And from a later email:
"Attached you'll find a fixed version of ModulInstall.cmake. Hopefully it
works for old CMake-versions. I removed the offending line, and the
compile went fine on my end."
I added support to find libxml2 in the 3rdparty package if available.
Now this file can find all libraries from the 32/64bit VS2008sp1 dependency package except collada. I will add that later.
"
I don't understand the changes to ReaderWriterFBX.cpp - (i) strings.h isn't a standard header, (ii) the ISO-conformant form is _strnicmp (with the underscore). Does the existing code not compile for you? If not we'll have to do some #ifdef nastiness."
latest OSG source code with Visual Studio 2010 express, without
setting too many options and without facing unexpected errors. But at
present, the compilation process will fail because the INSTALL project
'cannot find' generated DLLs while copying files. I have looked into
the build directory and found that the places of generated file
folders were just different from previous VS versions. In this case,
the old hack in OsgMacroUtils.cmake may become invalid:
MACRO(HANDLE_MSVC_DLL)
#this is a hack... the build place is set to lib/<debug or
release> by LIBARARY_OUTPUT_PATH equal to OUTPUT_LIBDIR
#the .lib will be crated in ../ so going straight in lib by
the IMPORT_PREFIX property
#because we want dll placed in OUTPUT_BINDIR ie the bin folder
sibling of lib, we can use ../../bin to go there,
...
ELSE(NOT MSVC_IDE)
SET_TARGET_PROPERTIES(${LIB_NAME} PROPERTIES PREFIX
"../../bin/${LIB_PREFIX}${LIB_SOVERSION}-" IMPORT_PREFIX "../")
ENDIF(NOT MSVC_IDE)
ENDMACRO(HANDLE_MSVC_DLL)
Here the prefix "../../bin" may need to be fixed. I just modified it to:
IF(MSVC_VERSION LESS 1600)
SET_TARGET_PROPERTIES(${LIB_NAME} PROPERTIES PREFIX
"../../bin/${LIB_PREFIX}${LIB_SOVERSION}-" IMPORT_PREFIX "../")
ENDIF()
It should keep compatible with old MSVC versions. There are similar
fixes in the SETUP_PLUGIN and SETUP_EXE macros. I haven't tested them
on more platforms.

Mathieu Marache, he added the last missing piece to this puzzle.
I think it is safe to commit these changes to trunk, as the traditional
way via dylibs should work as before.
Here's some more info how to get frameworks:
With these modifications it is possible to compile frameworks on OS X,
when you set the Cmake-option OSG_COMPILE_FRAMEWORKS to true. If you
want to embed the frameworks in your app-bundle make sure to set
OSG_COMPILE_FRAMEWORKS_INSTALL_NAME_DIR accordingly.
You'll have to build the install-target of the generated xcode-projects
as this sets the install_name_dirs of the frameworks and plugins."
Windows. If the 3rdparty directory isn't available it will use the
directory names subversion uses such as 3rdParty_win32binaries_vs71
3rdParty_win32binaries_vs80sp1 3rdParty_win32binaries_vs90sp1. That
helps when as we are building both vs71 and vs80, and probably vs90 in
the future at the same time in addition to not having to rename the
directory once it is downloaded. It also adds the _i suffix to match
some of the libraries.
"
currently only Debug appends "d" so the Release and MinSizeWithDebInfo
(and MinSizeRel) all produce the same filenames. This set of changes
lets each build type have a cmake defined string appended, defaulting
to Release none, Debug d, RelWithDebInfo rd, MinSizeRel s. But a user
still can have Release, RelWithDebInfo, and MinSizeRel to produce the
same filenames. It does so by setting the preprocessor define
OSG_LIBRARY_POSTFIX in src/osgDB/CMakeLists.txt to one of the
previously defined cmake variables CMAKE_DEBUG_POSTFIX
CMAKE_RELEASE_POSTFIX CMAKE_RELWITHDEBINFO_POSTFIX
CMAKE_MINSIZEREL_POSTFIX. This method cuts down on the #ifdef _DEBUG
#else preprocessor directives in Registry.cpp as the extension is
always passed in OSG_LIBRARY_POSTFIX. That and __MINGW32__ didn't
have the _DEBUG check which looks like a bug."

synchronization, improve capture device support.
here how to use it to display a capture device:
osg::Options* options = new osg::Options;
options->setPluginStringData("captureWantedWidth", "800");
options->setPluginStringData("captureWantedHeight", "600");
options->setPluginStringData("captureWantedFps", "30");
options->setPluginStringData("captureVideoDevice", "USB Video Device" );
options->setPluginStringData("captureSoundDevice", "");
then
osgDB::readImageFile("capture.directshow", options)
you can use a graphedit application to list devices available in
directshow.
for classic avi file you just need to do a
osgDB::readImageFile("file.avi.directshow");
You will need of course to install the codec needed by directshow to
read the avi files.
I recommand this tool http://avicodec.duby.info/, that check which
video/sound codec is needed to play an avi file.
You can test it with the osgmovie example.

The collada dom Makefiles actually build a framework called Collada14Dom.framework (debug: Collada14Dom-d.framework). The current CMake rules, however, only look for collada14dom. Normally, the difference in case wouldn't matter but the rule fails on case sensitive HPFS partitions.
