AVIDemo

AVIDemo addresses a small group of developers and programmers interested in the capabilities offered by the AVIOutputStream class. This particular piece of software does that in a pretty nifty way, in the least possible period of time.First things first, the AVIOutputStream class delivers you with the necessary low-level support in order to quickly and easily write encoded audio / video samples within AVI 1.0 container files. Although, generally, an AVI 1.0 file length cannot be larger than one gigabyte, the AVIOutputStream class extends this limitation to four gigabytes despite the fact that generated AVI files are not 100% playable on all of the available devices.AVIDemo comes packed within a JAR file that, upon running it does nothing else but to create three different AVI sample files including three versions of the same movie clip: RAW, RLE8 and JPG. As expected, the RAW file is the largest of the three, “weighing” 14.60 megabytes, while the other two only 43.5 kilobytes, respectively 2.19 megabytes. The differences in quality can be investigated with the naked eye.In the AVI 1.0 format, AVIOutputStream can write images as frames and every single one of them must present the same format and even quality if choosing to go with the JPG compression. Moreover, the frames must be equal in duration, as well. In short, the AVIOutputStream class helps you rapidly create new video files just by specifying the format as well as the frame rate.To sum it all up, the AVIDemo application software serves just as a showcase to demonstrate the power of the aforementioned Java class. This is its only goal and what it does is fast and witty. In certain cases, the time it takes to generate the AVI files makes you feel that the program does not do anything.
