Smacker Reverse Engineered

January 12th, 2006 by Multimedia Mike

One of my contacts notified me that he has reverse engineered the Smacker multimedia system. Hopefully we will get a description published soon and put a fresh open source implementation out in the wild.

This is great. This is one of the oldest and most enduring multimedia systems in the field, and one of the most widespread– The official website boasts of its use in over 2,600 software titles.

On Portable Programs

January 8th, 2006 by Multimedia Mike

Someone once asked on one of the xine mailing lists, “Is xine big endian or little endian?” Clearly, the person was confused but his heart was in the right place: He had heard about the endianness issue and that it affects machine portability somehow. Here is Multimedia Mike’s quick and easy guide to what you need to know about endianness and platform portability:


When the CPU interacts with the outside world, the CPU needs to worry about endianness.
