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) You can download this demo here: http://home.scarlet.be/~tsi46445/blender/VideoTextureDemo.blend http://home.scarlet.be/~tsi46445/blender/trailer_400p.ogg

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.
