Play or edit a movie Use the jit.movie for working with movie files - playback, editing, import, export, effect generation and direct-to-video-output-component streaming. This document refers to the qt engine version of jit.movie. Cycling '74 Jitter bang, messages in TEXT_HERE bang, messages in TEXT_HERE out TEXT_HERE dumpout TEXT_HERE char Adapt output matrix dimensions to movie size flag Enable automatic matrix output. Enable automatic matrix output when bound to jit.world. Autoplay on movie open flag Autoplay on movie open flag (default = 1) Output matrix's color encoding The output matrix's color encoding. 32 bit only. ARGB (alpha, red, green, blue) colormode UYVY (YUV 4:2:2 packed) colormode Render context name A render context name, used when output_texture is enabled. The portion of the output matrix written to by the input frame The portion of the output matrix used for decompressing media to the internal matrix (default = 0 0 (matrix width) (matrix height))
The bounds of the rectangle are expressed in the form left top right bottom. All values are relative to the top-left corner of the viewing area of the output matrix. Movie duration The duration of the movie. When setting the duration, the entire movie will be scaled to the new length, unless the additional argument noscale is used. In that case, the movie length is changed without scaling. For more precise control of scaling, use the scale message. Video engine backend. Video engine backend. This argument can only be set in the max box. If not specified, it is determined by the Video Engine Max preference. As of this writing, possible values include avf (Mac only) and qt. Internal FPS for the movie The approximate calculation of the movie's internal FPS rate Number of frames in the movie Frame reporting flag Frame reporting flag (default = 0). When enabled, the message framecalc will be sent from the rightmost outlet of the jit.movie object as each frame is processed, followed by the number of milliseconds spent doing so. Output interpolation flag Looping mode Looping mode (default = 1 (start to end)) 0 = no looping 1 = normal looping (start to end) 2 = palindrome looping (start to end to start to ....) 3 = no looping, but use looppoints to define playback limits Loop point end for movie The movie loop point end. Time is specified as time values. Movie loop points The movie loop points. Time is specified as time values. Loop notification flag Loop notification flag (default = 0). When enabled, the jit.movie object will send the message loopnotify when the playing movie passes the loop point. In palindrome looping mode, the message will be sent at both the beginning and the end of the movie. Movie loop point start The movie loop point start. Time is specified as time values. Native movie dimensions Native movie dimensions Load a movie file from disk Load a movie file from disk Movie file name Identifies the file name of a movie (Note: setting this attribute does not load a movie file). Fully specified path on disk for the movie The movie's fully-specified path on disk, if the movie has a disk-file (Note: setting this attribute does not load a movie file). Enable OpenGL texture output Enable OpenGL texture output (default = 0). When enabled an OpenGL texture is output instead of a Jitter matrix. The object's drawto attribute must be set to a valid gl context. An RGBA texture is output using the movie's native dimensions. When enabled, the following attributes have no effect:
adapt
colormode
dim
dstrect
srcrect
usedstrect
usesrcrect Movie rate The portion of the input matrix used when copying an input matrix to the internal matrix The portion of the movie to decompress into a matrix (default = 0 0 (movie width) (movie height)). The bounds of the rectangle are expressed in the form left top right bottom. All values are relative to the top-left corner of the viewing area of the movie. Output texture name Output texture name, when output_texture is enabled. Current time in the movie The current time in the movie. Time is specified as time values. Movie timescale The timescale for the movie (default = 600, but movie-dependent) Unique frame filter flag Unique frame filter flag (default = 0 (disabled)). When the flag is set, only new frames from the movie are output when the object receives a bang. If no new frame has been decompressed, the jit.movie object will not respond to the bang. Destination rect flag Destination rect flag (default = 0). When the flag is set, the dstrect attributes are used when copying an input matrix to the internal matrix. Source rect flag Source rect flag (default = 0). When the flag is set, the srcrect attributes are used when copying an input matrix to the internal matrix. Movie sound volume Time Seconds TEXT_HERE Time Milliseconds TEXT_HERE Seconds TEXT_HERE Position TEXT_HERE Milliseconds TEXT_HERE Looppoints Seconds TEXT_HERE Looppoints Milliseconds TEXT_HERE Read a movie from a disk file/URL/clipboard Reads a movie from a disk file, URL or the clipboard. If no argument is present, or if the symbol dialog is used for the src-name argument, a file selection dialog will be presented to choose a file. If the argument scrap is used for the src-name argument, the object will attempt to load a movie from the clipboard. If the argument is parsable as an http://, ftp:///, file://, or rtsp:// URL, the object will attempt to load a movie from that location. Otherwise, an argument is assumed to be a local file name.
If autostart is enabled, the movie will begin playing at once. Do a framedump Commences a framedump, in which the movie will start from a frame specified by start-frame (the default is 1) and automatically output frames in sequence (no bang or outputmatrix message is necessary) up to the frame specified by end-frame, skipping frame-skip frames between each frame. The default values are 1 for the start frame, and the total framecount of the movie for the end frame. The default frame-skip value is 1.
During operation, the message framedump current_frame is sent out the right outlet after each frame has been output. When finished, the message framedump done is output. Stop the frame dump process Stops the frame dump process. See framedump. Read a movie from a disk file asynchronously Asynchronously reads a movie from a disk file, if possible. If no argument is present, or if the symbol dialog is used for the src-name argument, a file selection dialog will be presented to choose a file. Any argument is assumed to be a local file name. At this time, asynchronous reading is not supported for URL- or clipboard-based movies; the normal read behavior will be used instead. Note: use of asyncread and preroll unloads any sections of the current movie loaded into RAM using the loadram method.
