What is MEncoder? 什么是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.

第一步,确保mencoder 包和其依赖的包都被安装好。可以用下面的命令来安装。
sudo apt-get install mencoder
You may also consider finding and install the w32codecs package, if you will be working with proprietary formats, such as wmv.
如果你有一些专有格式（例如：wmv格式）的文件要运行，你也可以考虑安装 w32codecs 包。
Basic Usage 基本用法
To use mencoder, you must specify at least an input file, an output file, an audio encoder and a video encoder. As a general framework, you can use the following to convert a video from any type that mplayer can read, to an avi file using mp3 audio encoding.
