MediaCoder is a free transcoder tools for audio and video, it is putting together many great software from the community of open source into one friendly GUI. At the video side, MEncoder used as the back-end and provides support for neraly all kind of video compression and container format, as well as rich and usefull video filtering features such as post-processing and 3D de-noise. On the audio side MPlayer and Winamp input plugins used as the decoders with various other encoders integrated, MediaCoder can simply batch transcode among any known audio formats, with tags transferred, file names generated, and even performing audio filtering (e.g. resample, normalize) on the fly.

Typical applications:
* Improving compression / reducing file size (audio+video -> audio+video)
e.g. MPG/VOB/AVI/RMVB/MOV/MP4 -> AVI/MKV/MP4 (Xvid/DivX/H.264 + MP3/OGG/AAC)
* Extracting audio track (audio+video -> audio)
e.g. MPG/VOB/AVI/RMVB/MOV/MP4 -> MP3/OGG/AAC/MPC
* Converting to normal VCD/DVD player ready video files (audio+video -> MPEG)
e.g. RMVB/MOV -> MPEG 1/2
* Converting from lossless or high-bitrate audio to low-bitrate audio to play with portable DAP (audio -> audio)
e.g. APE/FLAC/WavPack (+ CUE sheets) -> MP3/AAC/WMA
* Ripping CDs and compressing it on the fly
e.g. CD tracks-> APE/FLAC/WavPack/MP3/OGG/AAC/WMA/MPC
