MediaCoder is a freeware audio and video batch transcoder for Windows and WINE. It is developed by Stanley Huang, an individual developer, since 2005. In 2009, MediaCoder started to be branded under the name of Broad Intelligence Technologies product. MediaCoder is free of charge and is supported by bundling OpenCandy software recommendation service in its installer. There are no ads in the software GUI.
MediaCoder uses various open source audio and video codecs, among several proprietary codecs and tools to transcode different audio/video formats and has many extra features. Common uses for the program include compression, file type conversion and extraction of audio from video files. Many formats are supported, including MP3, Vorbis, AAC, Windows Media Audio, RealAudio, WAV, H.264, Xvid, DivX 4/5, MPEG-2, AVI, CD, and DVD.
Features
MediaCoder is a front-end/GUI for a collection of audio/video command line utilities and dynamic libraries (including audio/video codecs and multiplexers). MediaCoder maintains a unified parameter tree whose leaves (parameter values) can be altered through the application GUI, a web-based tree view, user interfaces for specific devices (e.g. PSP, iPhone) and conforming HTTP requests. It maps the parameter tree into command line options or calling parameters for various codecs and tools. MediaCoder pipes the decoder's output into the encoder's input, rather than using temporary files. This allows it to convert large amounts of data without using excessive disk space. Some of the included utilities are also patched to add extra interfaces.
MediaCoder has a built-in media streaming server which can be used to stream out audio and video files through HTTP protocol. It is able to apply on-the-fly transcoding for both audio and video streaming with some of its supported audio and video codecs.
MediaCoder has started to add experimental GPU-based video processing and encoding features since 0.7.1. The initial approach is done by using nVidia CUDA technology.

License controversy
On the 10th of June 2009 there was an open issue on FFmpeg's round-up, "Possible MediaCoder GPL violation" http://roundup.ffmpeg.org/roundup/ffmpeg/issue1162 that has yet to be resolved. There has been a response from MediaCoder http://blog.mediacoderhq.com/mediacoder-serious-statements/ about the issue. Other projects claim that they are violating the GPL licence too, however there have been no official statements as of yet.
