使用节点fluent-ffmpeg流mp4视频 [英] stream mp4 video with node fluent-ffmpeg
问题描述
我正在尝试使用节点 fluent-ffmpeg ， express 和 ejs 创建视频流服务器和客户端.有一段时间没有解决这个问题.我想做的是在特定时间开始播放视频.以下代码在Windows上使用 Safari浏览器进行了编码，但在其他代码下则进行了几秒钟的循环或显示
I'm trying to create video stream server and client with node fluent-ffmpeg, express and ejs. And a haven't solve this for a while. What I want to do is to play video beginning by certain time. The following codes make it with Safari browser on windows but with others it makes a loop of a few seconds or it says
不支持视频格式
服务器代码(run.js):
app.get('/video', function(req, res) {
//define file path,time to seek the beegining and set ffmpeg binary
var pathToMovie = '../videos/test.mp4';
var seektime = 100;
proc.setFfmpegPath(__dirname + "/ffmpeg/ffmpeg");
//encoding the video source
var proc = new ffmpeg({source: pathToMovie})
.seekInput(seektime)
.withVideoBitrate(1024)
.withVideoCodec('libx264')
.withAspect('16:9')
.withFps(24)
.withAudioBitrate('128k')
.withAudioCodec('libfaac')
.toFormat('mp4');
//pipe
.pipe(res, {end: true});
});
客户端代码(index.ejs):
<html>
<head></head>
<body>
<video>
<source src="video/" type='video/mp4' />
</video>
</body>
</html>
请帮助.我到处搜索了解决方案，但没有找到
Help please. I searched everywhere solution but I didn't find
推荐答案
我相信，要在mp4或mp3中进行搜索，您需要让浏览器知道该内容的长度.在致电 ffmpeg 之前，请尝试插入此简短内容.这样应该可以获取视频文件的大小，并且您可以在流式传输数据之前相应地在响应中设置标头.
I believe that in order to seek within a mp4 or mp3, you need to let the browser know the length of that content. Try inserting this quick blurb before you make your call to ffmpeg. This should get the size of the video file and you can set the headers in the response accordingly before streaming the data.
在ffmpeg调用之前插入
var fs = require('fs');
var stat = fs.statSync(pathToMovie);
res.writeHead(200, {
'Content-Type': 'video/mp4',
'Content-Length': stat.size
});
