MediaCoder is an open source audio/video batch transcoder, putting together many excellent audio/video softwares from the open source community into one friendly GUI. On video side, MEncoder is used as back-end, which provides support for nearly all known video compression and container formats as well as rich and useful video filtering features (e.g. post-processing, 3D de-noise). On audio side, MPlayer and Winamp input plugins used as decoders, various 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
Extracting audio track
Converting to normal VCD/DVD player ready video files
Converting from lossless or high-bitrate audio to low-bitrate audio to play with portable DAP
Ripping CDs and compressing it on the fly

Supported source formats:

Audio: MP3, OGG/Vorbis, AAC, MusePack, WMA, RealAudio, FLAC, WavPack, APE/APL, WAV, CUE Sheets, and any other formats supported by Winamp input plugins
Video: AVI (Xvid/DivX/H.264), MPEG1/2/4, QuickTime (mov), WMV/ASF, RealMedia (rmvb), MP4, Matroska (mkv)
CUE Sheets

Supported target audio formats:

Lossy: MP3 (Lame), OGG/OGM (Vorbis), AAC (iTunes, Nero AAC Encoder, FAAC), AAC+/Parametric Stereo (CT, Helix), MusePack, WMA
Lossless: FLAC, WavPack, Monkey's Audio (APE), WMA Lossless, WAV
