42121590f4 == FFMPEG ==
Added central compatibility header file, which enables blender to compile
against very old ffmpeg versions as well as very new versions using the
*NEW* API. (Old API functions are simulated using macros and inline functions)

Added a whole lot of additional checks, tested against 6 different versions
down the timeline, hopefully, now finally all is well.

cb12337363 Code cleanup: remove source/kernel module, this wasn't really the kernel of
anything, only contained a hash map and functions to pass command line args
to the game engine. Moved those to container and BlenderRoutines modules.

37b9c9fe4d VideoTexture: improvements to image data access API.
- Use BGL buffer instead of string for image data.
- Add buffer interface to image source.
- Allow customization of pixel format.
- Add valid property to check if the image data is available.

The image property of all Image source objects will now
return a BGL 'buffer' object. Previously it was returning
a string, which was not working at all with Python 3.1.
The BGL buffer type allows sequence access to bytes and
is directly usable in BGL OpenGL wrapper functions.
The buffer is formated as a 1 dimensional array of bytes
with 4 bytes per pixel in RGBA order.

BGL buffers will also be accepted in the ImageBuff load()
and plot() functions.

It is possible to customize the pixel format by using
the VideoTexture.imageToArray(image, mode) function:
the first argument is a Image source object, the second
optional argument is a format string using the R, G, B,
A, 0 and 1 characters. For example "BGR" means that each
pixel will be 3 bytes, corresponding to the Blue, Green
and Red channel in that order. Use 0 for a fixed hex 00
value, 1 for hex FF. The default mode is "RGBA".

All Image source objects now support the buffer interface
which allows to create memoryview objects for direct access
to the image internal buffer without memory copy. The buffer
format is one dimensional array of bytes with 4 bytes per
pixel in RGBA order. The buffer is writable, which allows
custom modifications of the image data.

v = memoryview(source)

A bug in the Python 3.1 buffer API will cause a crash if
the memoryview object cannot be created. Therefore, you
must always check first that an image data is available
before creating a memoryview object. Use the new valid
attribute for that:

if source.valid:
    v = memoryview(source)
    ...	

Note: the BGL buffer object itself does not yet support
the buffer interface.

Note: the valid attribute makes sense only if you use
image source in conjunction with texture object like this:

# refresh texture but keep image data in memory
texture.refresh(False)
if texture.source.valid:
    v = memoryview(texture.source)
    # process image
    ...
    # invalidate image for next texture refresh
    texture.source.refresh()

Limitation: While memoryview objects exist, the image cannot be
resized. Resizing occurs with ImageViewport objects when the
viewport size is changed or with ImageFFmpeg when a new image
is reloaded for example. Any attempt to resize will cause a
runtime error. Delete the memoryview objects is you want to
resize an image source object.

fb649d5824 * cleaning up warnings (mostly windows). A collection of other warning fixes too (undefined function, assuming int, etc.)
This compiled fine with scons/msvc and scons/mingw (gcc 4.4.0). Please test and report any problems.

9216efcba2 == SCons ==
* bring back 'player' libtype, after investigation with ideasman.
  scons/mingw works nicely, for some reason msvc fails to link still, will look further into it.

20f39ec7d8 == SCons ==
* further cleaning of 'player' stuff. Now only 3 libs are remaining, of which ideally the stubs lib will be fixed at some point, fading away into the dark history of not-so-nice code. The current blenderplayer part is still a little bit hackish, I'll see if I can find a better alternative, for now it works good enough.

bade641408 == SCons ==
* first working changes to get blenderplayer linking
* blenderplayer/ moved into source/ (CMakeLists.txt changed for that too)
* added externs for bprogname to gp_ghost, so that it links properly

3f5115064a == SCons ==
* Add BGE_CXXFLAGS so we can get rid of hard-coded BGE compiler settings. This was only done for windows, but now linuxers and osxers should be able to set BGE-specific optimisation too. See the windows default configs for example.

d52400bfbd 2.50: svn merge https://svn.blender.org/svnroot/bf-blender/trunk/blender -r18677:19317
Notes:
* Sequence transform strip uses G.scene global, this is commented
  out now, should be fixed.
* Etch-a-ton code was most difficult to merge. The files already in
  2.5 got merged, but no new files were added. Calls to these files
  are commented out with "XXX etch-a-ton". editarmature.c and
  transform_snap.c were complex to merge. Martin, please check?
* Game engine compiles and links again here for scons/make/cmake
  (player still fails to link).

ab8e9ba3dd VideoTexture: reactivate VideoTexture for scons/cmake/makefile compilation systems, fix video streaming, fix camera support in Linux, add multi-thread cache service, fix crash when a VideoFFmpeg object could not be created.
The multi-thread cache service is activated only on multi-core processors.
It consists in loading, decoding and caching the video frames in a 
separate thread. The cache size is 5 decoded frames and 30 raw frames.
Note that the opening of video file/stream/camera is not multi-thread:
you will still experience a delay at the VideoFFmpeg object creation.
Processing of the video frame (resize, loading to texture) is still done
in the main thread.  Caching is automatically enabled for video file, 
video streaming and video camera. 

Video streaming now works correctly: the videos frames are loaded
at the correct rate. Network delays and frequency drifts are automatically
compensated. 
Note: an http video source is always treated as a streaming source,
even though the http protocol allows seeking. For the user it means that
he cannot define start/stop range and cannot restart the video except
by reopening the source. Pause/play is however possible.

Video camera is now correctly handled on Linux: it will not slow down the BGE.
A video camera is treated as a streaming source.

c3d74547be SCons:
* giving compileflags, cc_compileflags and cxx_compileflags to BlenderLib() now actually overrides any other setting (so there's no unclarity when ie. conflicting options are being specified in REL_CFLAGS et al). These are set after either release or debug flags, but before any *_WARN flags (so those stay maintained).
* add cxx_compileflags for GE parts on win32-vc to have better performance.
* NOTE: if platform maintainers (OSX and Linux) could check and do the same for their systems. Not vital, but probably very, very much welcomed by GE users.

bdfe7d89e2 Merge of trunk into blender 2.5:
svn merge https://svn.blender.org/svnroot/bf-blender/trunk/blender -r12987:17416

Issues:
* GHOST/X11 had conflicting changes. Some code was added in 2.5, which was
  later added in trunk also, but reverted partially, specifically revision
  16683. I have left out this reversion in the 2.5 branch since I think it is
  needed there.
  http://projects.blender.org/plugins/scmsvn/viewcvs.php?view=rev&root=bf-blender&revision=16683
* Scons had various conflicting changes, I decided to go with trunk version
  for everything except priorities and some library renaming.
* In creator.c, there were various fixes and fixes for fixes related to the -w
  -W and -p options. In 2.5 -w and -W is not coded yet, and -p is done
  differently. Since this is changed so much, and I don't think those fixes
  would be needed in 2.5, I've left them out.
* Also in creator.c: there was code for a python bugfix where the screen was not
  initialized when running with -P. The code that initializes the screen there
  I had to disable, that can't work in 2.5 anymore but left it commented as a
  reminder.

Further I had to disable some new function calls. using src/ and python/, as
was done already in this branch, disabled function calls:
* bpath.c: error reporting
* BME_conversions.c: editmesh conversion functions.
* SHD_dynamic: disabled almost completely, there is no python/.
* KX_PythonInit.cpp and Ketsji/ build files: Mathutils is not there, disabled.
* text.c: clipboard copy call.
* object.c: OB_SUPPORT_MATERIAL.
* DerivedMesh.c and subsurf_ccg, stipple_quarttone.

Still to be done:
* Go over files and functions that were moved to a different location but could
  still use changes that were done in trunk.

a8c4eef326 VideoTexture module.
The only compilation system that works for sure is the MSVC project files. I've tried my best to
update the other compilation system but I count on the community to check and fix them.
 
This is Zdeno Miklas video texture plugin ported to trunk. 
The original plugin API is maintained (can be found here http://home.scarlet.be/~tsi46445/blender/blendVideoTex.html)
EXCEPT for the following:

The module name is changed to VideoTexture (instead of blendVideoTex).

A new (and only) video source is now available: VideoFFmpeg()
You must pass 1 to 4 arguments when you create it (you can use named arguments):

VideoFFmpeg(file) : play a video file
VideoFFmpeg(file, capture, rate, width, height) : start a live video capture

file:
In the first form, file is a video file name, relative to startup directory.
It can also be a URL, FFmpeg will happily stream a video from a network source.
In the second form, file is empty or is a hint for the format of the video capture.
In Windows, file is ignored and should be empty or not specified.
In Linux, ffmpeg supports two types of device: VideoForLinux and DV1394. 
The user specifies the type of device with the file parameter:
   [<device_type>][:<standard>]
   <device_type> : 'v4l' for VideoForLinux, 'dv1394' for DV1394; default to 'v4l'
   <standard>    : 'pal', 'secam' or 'ntsc', default to 'ntsc'
The driver name is constructed automatically from the device types:
   v4l   : /dev/video<capture>
   dv1394: /dev/dv1394/<capture>
If you have different driver name, you can specify the driver name explicitely 
instead of device type. Examples of valid file parameter:
   /dev/v4l/video0:pal
   /dev/ieee1394/1:ntsc
   dv1394:ntsc
   v4l:pal
   :secam

capture: 
Defines the index number of the capture source, starting from 0. The first capture device is always 0.
The VideoTexutre modules knows that you want to start a live video capture when you set this parameter to a number >= 0. Setting this parameter < 0 indicates a video file playback. Default value is -1.

rate: 
the capture frame rate, by default 25 frames/sec

width: 
height: 
Width and height of the video capture in pixel, default value 0.
In Windows you must specify these values and they must fit with the capture device capability. 
For example, if you have a webcam that can capture at 160x120, 320x240 or 640x480, 
you must specify one of these couple of values or the opening of the video source will fail.
In Linux, default values are provided by the VideoForLinux driver if you don't specify width and height.

Simple example
**************
1. Texture definition script:

import VideoTexture

contr = GameLogic.getCurrentController()
obj = contr.getOwner()
if not hasattr(GameLogic, 'video'):
	matID = VideoTexture.materialID(obj, 'MAVideoMat')
	GameLogic.video = VideoTexture.Texture(obj, matID)
	GameLogic.vidSrc = VideoTexture.VideoFFmpeg('trailer_400p.ogg')
	# Streaming is also possible:
	#GameLogic.vidSrc = VideoTexture.VideoFFmpeg('http://10.32.1.10/trailer_400p.ogg')
	GameLogic.vidSrc.repeat = -1
	# If the video dimensions are not a power of 2, scaling must be done before
	# sending the texture to the GPU. This is done by default with gluScaleImage()
	# but you can also use a faster, but less precise, scaling by setting scale
	# to True. Best approach is to convert the video offline and set the dimensions right.
	GameLogic.vidSrc.scale = True
	# FFmpeg always delivers the video image upside down, so flipping is enabled automatically
	#GameLogic.vidSrc.flip = True

if contr.getSensors()[0].isPositive():
	GameLogic.video.source = GameLogic.vidSrc
	GameLogic.vidSrc.play()


2. Texture refresh script:

obj = GameLogic.getCurrentController().getOwner()
if hasattr(GameLogic, 'video') != 0:
  GameLogic.video.refresh(True)
