How to stream to a element using fluent-ffmpeg
19 mai 2017, par LukasI am writing on an
electron
application and I am trying to usefluent-ffmpeg
to create a streaming server and use a<video></video>
element to consume that stream. I wonder how to set upfluent-ffmpeg
and the<video></video>
usingflowplayer
like this :Server :
const express = require('express');
const ffmpeg = require('fluent-ffmpeg');
const app = express();
app.use(express.static(__dirname + '/flowplayer'));
app.get('/', function(req, res) {
res.send('index.html');
});
app.get('/video/:filename', function(req, res) {
res.contentType('flv');
// make sure you set the correct path to your video file storage
const pathToMovie = '/Users/luke/Movies/' + req.params.filename;
const proc = ffmpeg(pathToMovie)
// use the 'flashvideo' preset (located in /lib/presets/flashvideo.js)
.preset('divx')
// setup event handlers
.on('end', function() {
console.log('file has been converted succesfully');
})
.on('error', function(err) {
console.log('an error happened: ' + err.message);
})
// save to stream
.pipe(res, {end:true});
});
app.listen(4000);Webseite with
<video></video>
element :
<code class="echappe-js"><script src="https://code.jquery.com/jquery-1.11.2.min.js"></script><script src='http://stackoverflow.com/feeds/tag/flowplayer-7.0.4/flowplayer.min.js'></script>
<script><br />
require('./ffmpeg-server.js');<br />
</script>The main problem I see right now is to find a way to set up the right settings for
ffmpeg
(currently I am using thedivx
preset together with the video typevideo/mpeg4
in the HTML which (of course) does not work. -
"Error opening filters !" when using fluent-ffmpeg with Node
3 février 2015, par doremiI’m trying to get a basic example of html5 video streaming working in an express node app, but I keep running into ffmpeg errors that I’m unsure of how to resolve.
The input file/stream is the sample.mp4 located here.
Complete example :
var ffmpeg = require('fluent-ffmpeg');
var express = require('express');
var fs = require('fs');
var sampleApp = express();
var videoApp = express();
var SAMPLE_SERVER_PORT = 3000;
var VIDEO_SERVER_PORT = 5000;
sampleApp.get('/:video', function (req, res) {
var videoURL = 'http://localhost:' + VIDEO_SERVER_PORT + '/' + req.params.video;
return res.end('<video controls="controls" src=" + videoURL +"></video>');
});
videoApp.get('/:video', function(req, res) {
res.statusCode = 200;
res.setHeader('content-type','video/mp4');
var stream = fs.createReadStream('./samples/' + req.params.video);
var proc = ffmpeg(stream)
.format('mp4')
.size('320x?')
.videoBitrate('512k')
.videoCodec('libx264')
.fps(24)
.audioBitrate('96k')
.audioCodec('aac')
.audioFrequency(22050)
.audioChannels(2)
.on('error', function(err) {
console.log('an error happened: ' + err.message);
})
.pipe(res, { end:true });
});
var server = sampleApp.listen(SAMPLE_SERVER_PORT, function () {
console.log('Example app listening at http://%s:%s', server.address().address, SAMPLE_SERVER_PORT);
});
var videoServer = videoApp.listen(VIDEO_SERVER_PORT, function () {
console.log('Video Server listening at http://%s:%s', server.address().address, VIDEO_SERVER_PORT);
});The error (via console) :
an error happened: ffmpeg exited with code 1: Error opening filters!
ffmpeg configuration :
./configure --prefix=/usr/local --enable-gpl --enable-nonfree --enable-libass \
--enable-libfdk-aac --enable-libfreetype --enable-libmp3lame --enable-libopus \
--enable-libtheora --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libxvid --enable-libfaac --enable-libfdk-aacAny input would be greatly appreciated.

FFmpeg skips rendering frames
18 août 2018, par Srdjan M.While I extract frames from a video I noticed that
ffmpeg
wont finish rendering certain images. The problem ended up being byte "padding" between twojpeg
images. If my buffer size is4096
and if in that buffer are located bytes from previous image and next image and if they are not separated by any number of bytes, then next image is not rendered properly. Why is that ?-i path -f image2pipe -c:v mjpeg -q:v 2 -vf fps=25 pipe:1
Rendered frame :
Code sample :
public void ExtractFrames()
{
string FFmpegPath = "Path...";
string Arguments = $"-i { VideoPath } -f image2pipe -c:v mjpeg -q:v 2 -vf fps=25/1 pipe:1";
using (Process cmd = GetProcess(FFmpegPath, Arguments))
{
cmd.Start();
FileStream fStream = cmd.StandardOutput.BaseStream as FileStream;
bool Add = false;
int i = 0, n = 0, BufferSize = 4096;
byte[] buffer = new byte[BufferSize + 1];
MemoryStream mStream = new MemoryStream();
while (true)
{
if (i.Equals(BufferSize))
{
i = 0;
buffer[0] = buffer[BufferSize];
if (fStream.Read(buffer, 1, BufferSize) == 0)
break;
}
if (buffer[i].Equals(255) && buffer[i + 1].Equals(216))
{
Add = true;
}
if (buffer[i].Equals(255) && buffer[i + 1].Equals(217))
{
n++;
Add = false;
mStream.Write(new byte[] { 255, 217 }, 0, 2);
File.WriteAllBytes($@"C:\Path...\{n}.jpg", mStream.ToArray());
mStream = new MemoryStream();
}
if (Add)
mStream.WriteByte(buffer[i]);
i++;
}
cmd.WaitForExit();
cmd.Close();
}
}
private Process GetProcess(string FileName, string Arguments)
{
return new Process
{
StartInfo = new ProcessStartInfo
{
FileName = FileName,
Arguments = Arguments,
UseShellExecute = false,
RedirectStandardOutput = true,
CreateNoWindow = false,
}
};
}Video sample (> 480p) with length of 60 seconds or higher should be used for testing purposes.
