Code for converting videos of any format into flv using php

Use php to convert any video format into the flv implementation code. for details, refer. The code is as follows:
Define ("ROOT_DIR", dirname (_ FILE __));
Class EcodeFlv {
Var $ fromFile; // uploaded File
Var $ toFilePath; // Save the file path
Var $ toPicPath; // save the image path
Var $ mpeg; // path of the ffmpeg.exe file
Var $ mencode; // The path of the mencode.exe file
Var $ convert tofile; // convert the file command
Var $ convert topic; // Convert Image command
Var $ toFileName; // converted file name
Var $ mpegComm; // The conversion command of ffmpeg.exe
Var $ mencodeComm; // mencode.exe command
Var $ mpegType;
Var $ mencodeType;
Var $ midi; // The path of mdi.exe
Var $ unzip Midi; // mdi.exe command
// Initialization class
