MediaCoder is a proprietary transcoding program for Microsoft Windows, developed by Stanley Huang since 2005.

MediaCoder uses various open-source (and several proprietary) audio and video codecs to transcode media files to different audio/video formats.

[4] The program uses a wizard to create files, but that can also be adjusted manually by the drag-and-drop function.

MediaCoder was a nominee of SourceForge.NET 2007 Community Choice Award of Best Project for Multimedia along with Audacity, InkScape and FFDShow.

[6] Prior to 2008, MediaCoder was a free and open-source software application and was available on SourceForge.
