Windows Process Description:

The module ir32_32.dll is commonly known as Indeo Codec operating in 32-bit platform that contains functions for Indeo Video coding and decoding applications.

Intel Corporation first introduced Indeo Video Codec in Silicon Community in 1992. Unfortunately though, Indeo was sold to Ligos Corporation in 2000. Its original version was connected with Intel's DVI video stream format, a hardware-only codec for the compression of television-quality video onto compact disks. Indeo was known to be one of the first codecs providing full-speed video playback sans using hardware support.

The ir32_32.dll file forms an important part in Indeo codec's architecture. During the development of what became the Pentium microprocessor, Intel's Design team introduced one of the first, and at the time highest-quality, software-only video codecs. At its public introduction, Indeo Video was the only video codec supported in both the Microsoft (Video for Windows) and Apple Computer's QuickTime software environments, as well as by IBM's software systems of the time.

The original Indeo codec took a bulk of computation to encode a video stream than to decode it that is why it is considered "asymmetrical". Intel's ProShare video conferencing system took advantage of this by the use of hardware acceleration to encode the stream and thus requiring an add-in card. The ir32_32.dll application allowed the stream to be displayed on any personal computer. Several errors are experienced by Windows users associated with the DLL ir32_32.dll is missing when running Indeo codec.

The ir32_32.dll file linked the Indeo Video Interactive feature, a wavelet-based codec that included novel features such as chroma-keyed transparency and hot spot support, aimed at video game developers. When the program was sold to Ligos, Intel produced several different versions of the codec between 1993 and 2000, based on very different underlying mathematics and having different features still incorporating the ir32_32.dll file notwithstanding.

Though Indeo in the mid-1990s saw significant usage, it stayed proprietary. Intel however, went slow in the development and stopped active marketing. Indeo codec was quickly overrun in popularity by the rise of MPEG codecs.
