| - | ====== mglMovie ====== | ||
| - | **availability**: [[mgl:beta|mgl 2.0]] Mac OS X 64-bit Matlab only\\ | ||
| - | **usage**: movieStruct = mglMovie(filename,position) or mglMovie(movieStruct,command,<argument>);\\ | ||
| - | **purpose**: Used to display quicktime movies. (This *only* works on 64 bit Mac. There is some issue with the quicktime library QTKit and threads which does not seem to be a problem on 64 bit). You also need to be using a cocoa window, so make sure to set mglSetParam('movieMode',1) before running mglOpen. Check the sample experiment, taskTemplateMovie for a working example. | ||
| - | |||
| - | Also, note that the movies will play in front of the openGL buffer. Thus you can't draw on top of the movie and mglFrameGrab won't grab the movie frame -- you can grab movie frames with mglMovie(m,'getFrame'); | ||
| - | |||
| - | To init the movie, you open with a filename, and an optional position array [x y width height] and save the returned structure. | ||
| - | |||
| - | mglSetParam('movieMode',1); | ||
| - | mglOpen; | ||
| - | m = mglMovie('movie.mov'); | ||
| - | |||
| - | Then you can run commands on the movie: | ||
| - | |||
| - | mglMovie(m,'play'); | ||
| - | |||
| - | If no position is specified, the movie will be made to fill the display. Then pass in the structure with any of the following commands: | ||
| - | |||
| - | ^ command ^ purpose ^ | ||
| - | |0:'close" | Close the movie. After you run this, you will no longer be able to play the movieStruct again since the memory will have been released.| | ||
| - | |1:'play' | Play the movie | | ||
| - | |2:'pause' | Pause the movie| | ||
| - | |3:'gotoBeginning' | Goto the beginning of the movie| | ||
| - | |4:'gotoEnd' |Goto the end of the movie| | ||
| - | |5:'stepForward' |Step one frame forward in the movie| | ||
| - | |6:'stepBackward'| Step one frame backward in the movie| | ||
| - | |7:'hide' |Hide the movie. This does not close the movie, so you will be able to show the movieStruct again by using show.| | ||
| - | |8:'show'| Show the movie after it has been hidden| | ||
| - | |9:'getDuration' | Get a string that represents the length of the movie| | ||
| - | |10:'getCurrentTime' |Gets the current time of the movie| | ||
| - | |11:'setCurrentTime' |Sets the current time of the movie to the string\passed in. Make sure the string is one returned from getCurrentTime| | ||
| - | |12:'getFrame' |Returns a nxmx3 matrix containing RGB data for current frame| | ||
| - | Here is a sample quicktime movie that should work with mglMovie: {{:mgl:bosque.mov|}} | ||
