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)

3bb82a27fc == SCons ==
* This commit is all of the rewrite work done on the SCons system. For
  documentation see doc/blender-scons.txt and doc/blender-scons-dev.txt.
  Also http://mediawiki.blender.org/index.php/BlenderDev/SconsRefactoring
  contains valuable information, along with what still needs to be done.

    - linux, os x and windows compile now.
    - files are compiled to BF_INSTALLDIR (see config/(platform)-config.py)
        - NOTE: Jean-Luc P will commit sometime during the weekend proper
          appit() for OS X. For now, copy the resulting binary to an
          existing .app bundle.
    - features:
        - cleaner structure for better maintenance
        - cleaner output during compile
        - better handling of build options
        - general overall speed increase
        - see the wiki for more info

  Cygwin, FreeBSD and Solaris systems still need work. For these systems:
    1) copy a config/(platform)-config.py to ie. config/cygwin-config.py
    2) set the proper defaults for your platform
    3) mail me at jesterking at letwory dot net with you configuration. if
       you need any modifications to the system, do send a patch, too.

  I'll be giving first-aid today and tomorrow, after that it'll be all
  regular development work :)

745fc2f9d0 updated SConstruct and Makefile so that if you compile the gameengine, is always enables bullet, independent of sumo/ode.
So for the 2.4 release, both bullet AND sumo will be enabled. You can choose in the world buttons which physics engine is active for a scene.

sorry if this breaks your builds!

208da2a5d0 Added support for compiling BULLET with scons on windows
using bandoler's patch as a basis (thanks!).

A couple of notes:

-  This is for windows only, I did not have a chance to try linux yet.

-  SConscript for PHY_Bullet may need tweaking (plus support
 for other platforms), but at least it's in there :)

Any problems, shout :)

d5fde6c48b Added #!/usr/bin/python standard script identifier to the start of SConscript files.
Makes text editors identify SConscripts as Python, and syntax highlight properly.

fc080d30d6 Added preliminary support for GamePlayer building with SCons. GPG_ghost and GPC_common are now being built. These will be built by setting BUILD_BLENDER_PLAYER to true in config.opts. BUILD_GAMEENGINE must be set to true, too. 2004-04-08 10:40:12 +00:00

e1ab3cf480 SCons updates
* Game engine can now be build on Linux. By default this feature is disabled.
  The reason is that you need to have a precompiled version of the ode library
  for your gcc version.
  To enable ode support you need to do the following:
  - compile ode.
  - set BUILD_GAMEENGINE = 'true' in the config.opts file.
  - set USE_PHYSICS='ode' in the config.opts file.
  - set the ODE_INCLUDE and ODE_LIBPATH to valid locations.

* Linking order has changed for the game engine
  There are cyclic dependencies between libraries. On linux we have to do some
  duplicate linking. I looked at the order of linking in source/Makefile, and
  did some clean up.

9330e553e8 SCons updates
* libraries are now generated in [BUILD_DIR]/lib
* passed the user_options to all libraries now.
  This means I could remove a couple of Export/Import lines.
* Changed the order in source/blender/src/SConscript and
  source/gameengine/SConscript.
  All libraries are now sorted alphabetically. This has no impact on the build
  process.

2883110a54 SCons updates: (All done by jesterKing)
* Windows .exe file now includes the blender icon.
* Builds with game engine on Windows only.
  I tried building the game engine on Linux, but I get weird errors when
  building with ode. There's a dirty #include path in
  Physics/BlOde/OdePhysicsEnvironment.cpp (../ode/src/joint.h). gcc doesn't
  like this somehow.
* Other platforms need to add a couple of flags to the SConstruct:
  use_sumo, use_ode, solid_include and ode_include
