Question

要求是读取目录中的所有文件并合并它们。我正在使用node fluent-ffmpeg来实现这一目标。首先，通过添加.input来读取目录中连接字符串的所有文件。

var finalresult="E:/ETV/videos/finalresult.mp4"
outputresult : It consists of all the files read in the directory.

/*Javascript*/
MergeVideo(outputresult);
function MergeVideo(outputresult){
console.log("in merge video");
var videostring = "";

for(i=1;i<5;i++)
    {
videostring = videostring+".input("+"'"+outputresult[i]+"'"+")";
}
console.log("Video String"+videostring);
    var proc = ffmpeg()+videostring
    .on('end', function() {
      console.log('files have  succesfully Merged');
        })
    .on('error', function(err) {
      console.log('an error happened: ' + err.message);
    })
    .mergeToFile(finalresult);
}

它出现以下错误：

TypeError: Object .input('ETV 22-02-2015 1-02-25 AM.mp4').input('ETV 22-02-2015
9-33-15 PM.mp4').input('ETV 22-02-2015 9-32-46 AM.mp4').input('ETV 22-02-2015 8-
32-44 AM.mp4') has no method 'on'

感谢任何帮助。

试试这个

var fluent_ffmpeg = require("fluent-ffmpeg");

var mergedVideo = fluent_ffmpeg();
var videoNames = ['./video1.mp4', './video2.mp4'];

videoNames.forEach(function(videoName){
    mergedVideo = mergedVideo.addInput(videoName);
});

mergedVideo.mergeToFile('./mergedVideo.mp4', './tmp/')
.on('error', function(err) {
    console.log('Error ' + err.message);
})
.on('end', function() {
    console.log('Finished!');
});

使用节点fluent ffmpeg合并多个视频
