  • Stream ffmpeg output to flash player in node.js

    10 décembre 2013, par dave

    I'm using ffmpeg to take a video source and live stream it to the browser in flash.

    Here's the code (using expressjs) :

    app.get('/stream', function(req, res) {
    

    
    var command = spawn('ffmpeg', ['-re','-i','video.avi','-c:v','libx264','-c:a','libfaac','-ar',44100,'-f','flv','-']);
    

    
    res.setHeader("Accept-Ranges", "bytes");
    
    res.setHeader("Content-Type", "video/x-flv");        
    
    command.stdout.pipe(res);
    

    
});

    EDIT : The command this uses is :

    ffmpeg -re -i video.avi -c:v libx264 -c:a libfaac -ar 44100 -f flv -

    If I load this URL in the browser directly, it downloads the flv file and I can play it back in VLC player. However, when I use this in a player like JWPlayer or even try to simply embed, it doesn't show or anything.

    Any idea what I could be missing here ?

    Thank you !

    EDIT : Here's the output from ffmpeg, after this it's just the bytes that continue on as it encodes.

    I want to play an RTSP live stream that I get internally. I’m using ffplay to play this. And this is the command that I use :
    ffplay -i "rtsp://test.vibrtech.com/mov/video.sav?MAC=00C2100F124&channel=2&GUID=betauser", but when I execute, I get Invalid data found when processing input error. The complete error output is given below :

  • Play stream via FFplay (FFmpeg) in Docker

    18 mars 2020, par Matan Marciano

    It is possible to play a video file via ffplay in Docker ?
    I have tried to build this docker :

    Dockerfile :

    FROM ubuntu:18.04
    
RUN apt-get update && apt-get install -y ffmpeg

    After run this docker with a command :

    docker run -v /demo:/demo ffmpeg-test bash -c "ffplay -i /demo/test.mp4"

    I got ffplay logs without any player window.
    What am I missing ?
