What is MEncoder?

Mencoder is a companion program to the MPlayer media player that can be used to encode or transform any audio or video stream that MPlayer can read. See the RestrictedFormats wiki page for instructions for enabling non-free formats in MPlayer and gmplayer. For more information visit the MPlayer web site. Filters include cropping, scaling, vertical flipping, horizontal mirroring, expanding to create letterboxes, rotating, brightness/contrast, changing the aspect ratio of the video's pixels, colorspace conversion, hue/saturation, color-specific gamma correction, filters for reducing the visibiltiy of compression artifacts caused by MPEG compression (deblocking, deringing), automatic brightness/contrast enhancement (autolevel), sharpness/blur, denoising filters, and several different ways of deinterlacing. Certain filters capable of reversing telecine that do not work well with MPlayer can be used as well.

How To Use MEncoder

mencoder <input_movie> -oac mp3lame -ovc lavc -o output_movie.avi 

Audio/Video encoders

To see a list of audio encoders supported on your installation, run

mencoder -oac help 

To use an audio encoder, specify it as in the example above with -oac <audio_encoder>. Similarly for video encoders, search with

mencoder -ovc help
