发生错误：产生ENOENT，node.js和FFmpeg

Question

我在一次噩梦中试图解决这个问题。昨天我问了一个问题，但到目前为止，长话短说，我一生无法解决。

我要做的就是在node.js应用程序中使用FFmpeg将.avi文件转码为.flv文件，这仅适用于FFmpeg的命令行，而在应用程序中无效，这是代码：

var ffmpeg = require('fluent-ffmpeg');

//make sure you set the correct path to your video file
var proc = new ffmpeg({ source: 'C:/Users/Jay/Documents/movie/drop.avi', nolog: true });

//Set the path to where FFmpeg is installed
proc.setFfmpegPath("C:\\Users\\Jay\\Documents\\FFMPEG\\bin");

proc
//set the size
//.withSize('50%') <-- error appears after this line

// set fps
//.withFps(24)

// set output format to force
//.toFormat('flv')

// setup event handlers
.on('end', function() {
    console.log('file has been converted successfully');
})
.on('error', function(err) {
    console.log('an error happened: ' + err.message);
})
// save to file <-- the new file I want -->
.saveToFile('C:/Users/Jay/Documents/movie/drop.flv');

该错误出现在上面指定的行上，不是红色书写的错误，而是简单的说：

an error happened: spawn ENOENT

有人遇到过这个吗？

Ben Fortune为我修复了该错误，结果我忘了在安装FFmpeg的路径中指定ffmpeg.exe。这是代码的更新版本：

var ffmpeg = require('fluent-ffmpeg');

//make sure you set the correct path to your video file
var proc = new ffmpeg({ source: 'C:/Users/Jay/Documents/movie/drop.avi', nolog: true });

//Set the path to where FFmpeg is installed
proc.setFfmpegPath("C:\\Users\\Jay\\Documents\\FFMPEG\\bin\\ffmpeg.exe"); //I forgot to include "ffmpeg.exe"

proc
//set the size
.withSize('50%')

// set fps
.withFps(24)

// set output format to force
.toFormat('flv')

// setup event handlers
.on('end', function() {
    console.log('file has been converted successfully');
})
.on('error', function(err) {
    console.log('an error happened: ' + err.message);
})
// save to file <-- the new file I want -->
.saveToFile('C:/Users/Jay/Documents/movie/drop.flv');
