Safe to call this right after loading a new movie without having to Method is called in this routine prior to creating new buffers, so it’s This is called every time a video file is loaded. Each frame, the pixel buffer memory is mapped andįrame data is copied over to the GPU from the decoder. Setup texture buffers which hold frame data. Use setAttribute() and val2array() instead. _set ( attrib, val, op = '', log = None ) ¶ _setCurrent() method which handles the switch. _pixelTransfer ( ) ¶Ĭopy pixel data from video frame to texture. Requires self.rgb, lorSpace and ntrast _getPolyAsRendered ( ) ¶ĭEPRECATED. _getDesiredRGB ( rgb, colorSpace, contrast ) ¶Ĭonvert color to RGB while adding contrast.

Call this when tearing down thisĬlass or if a movie is stopped. This is called by the draw() method to blit the video to the displayįree texture and pixel buffers. _calcSizeRendered ( ) ¶īy _updateVertices() and verticesPix _drawRectangle ( ) ¶ This functionality is now handledīy _updateVertices() and verticesPix.

Legacy property for setting the foreground color of a stimulus in RGB, instead use obj._foreColor.rgb TypeĭEPRECATED in 1.80.00. Loop ( bool) – Whether to start the movie over from the beginning if draw is called andĪutoStart ( bool) – Automatically begin playback of the video when flip() is called. If aįloat, values between 0 and 1 may be used. Volume ( int or float) – If specifying an int the nominal level is 100, and 0 is silence. If None, the nativeįlipVert ( bool) – If True then the movie will be top-bottom flipped.įlipHoriz ( bool) – If True then the movie will be right-left flipped. Size ( ArrayLike or None) – Size of the video frame on the window in units. Units ( str) – Units to use when sizing the video frame on the window, affects how Raised if you are not using the preferred player. By default, the ‘preferred’ libraryīy PsychoPy developers is used. MovieLib ( str or None) – Library to use for video decoding. If an empty string, no file willīe loaded on initialization but can be set later. Win ( Window) – Window the video is being drawn to.įilename ( str) – Name of the file or stream URL to play. MovieStim ( win, filename = '', movieLib = 'ffpyplayer', units = 'pix', size = None, pos = 0.0, 0.0, ori = 0.0, anchor = 'center', flipVert = False, flipHoriz = False, color = 1.0, 1.0, 1.0, colorSpace = 'rgb', opacity = 1.0, contrast = 1, volume = 1.0, name = '', loop = False, autoLog = True, depth = 0.0, noAudio = False, interpolate = True, autoStart = True ) ¶Ĭlass for presenting movie clips as stimuli.

Start or continue a paused movie from current position. Whether every change in this stimulus should be auto logged.ĭraw the current frame to a particular window.ĭetermines whether the stimulus should be automatically drawn on every frame flip. The name ( str) of the object to be using during logged messages about this stim.

The size (width, height) of the stimulus in the stimulus unitsĭetermines how visible the stimulus is relative to background. The orientation of the stimulus (in degrees).
