For sending large amounts of media data—such as video—over the internet, TCP is more reliable than UDP because the receiving computer can check that it has received packets in the proper order, and it sends back an acknowledgement messages so that the sending computer knows whether the packet was successfully received. For large packets, it's best to put all the data into a Jitter matrix and send that via TCP.
This patch demonstrates a way to create a video delay effect using jit.matrixset. The jit.matrixset object is essentially an array of Jitter matrices. One of the things you can do with such an array is store a set of past frames of a video to recall later. Here we use the array as a circular buffer of the most recent 30 video frames to come out of jit.qt.movie.
This program assumes that you have a folder of image files (jpg, etc.) that you want to show as a slideshow. This program also assumes that those images all have the same dimensions.
The program assumes images that are 320x240 pixels. If you want to use another size, you should change the dimensions of the jit.qt.movie objects and the size of the jit.window. Images that do not have a 4:3 aspect ratio will get distorted when shown fullscreen, unless some adjustments are made.
This patch uses jit.lcd to draw white text on a black background, uses that monochrome image as the color and alpha channels, colorizes the text using jit.scalebias, and then does an alphablend of the text with a movie.
This patch shows the basics of displaying a movie with Jitter, and also shows the use of movie attributes to learn and use important information about the movie, how to jump around randomly within the movie, an easy way to fade the movie in or out, and how to fill the computer screen with the movie.
This example shows you a way to center an image file in jit.window (or jit.world), while retaining the original dimensions of the image.
This example shows a way to divide your list into three-item groups with zl.group, then put each of those values into one of the three planes of jit.matrix.
Here is a patch for choosing between multiple video effects.
