  • Ffmpeg send duration of video to client (using node-fluent-ffmpeg)

    26 mai 2013, par Vprnl

    I'm really new to the world of ffmpeg so please excuses me if this is a stupid queston.

    I'm using the module Node-fluent-ffmpeg to stream a movie and convert it from avi to webm with FFMPEG.

    So far so good (it plays the video), but I'm having trouble parsing the duration to the player. It also gives me an error even though I plays the video.

    my code is as followed :

    var stat = fs.statSync(movie);
    

    
var start = 0;
    
var end = 0;
    
var range = req.header('Range');
    
if (range != null) {
    
start = parseInt(range.slice(range.indexOf('bytes=')+6,
    
  range.indexOf('-')));
    
end = parseInt(range.slice(range.indexOf('-')+1,
    
  range.length));
    
}
    
if (isNaN(end) || end == 0) end = stat.size-1;
    
if (start > end) return;
    

    
var duration = (end / 1024) * 8 / 1024;
    

    
res.writeHead(206, { // NOTE: a partial http response
    
    'Connection':'close',
    
    'Content-Type':'video/webm',
    
    'Content-Length':end - start,
    
    'Content-Range':'bytes '+start+'-'+end+'/'+stat.size,
    
    'Transfer-Encoding':'chunked'
    
});
    

    
var proc = new ffmpeg({ source: movie, nolog: true, priority: 1, timeout:15000})
    
    .toFormat('webm')
    
    .addOptions(['-probesize 900000', '-analyzeduration 0', '-minrate 1024k', '-maxrate 1024k', '-bufsize 1835k', '-t '+duration+' -ss'])
    
    .writeToStream(res, function(retcode, error){
    
    if (!error){
    
        console.log('file has been converted succesfully',retcode);
    
    }else{
    
        console.log('file conversion error',error);
    
    }
    
});

    I set the header with a start and a end based on this article : http://delog.wordpress.com/2011/04/25/stream-webm-file-to-chrome-using-node-js/

    I calculate the length in seconds in the variable duration.

    The error FFmpeg is giving me is :

    The client side player (which is VideoJs) says the file is infinite/NaN in length.

    I feel like I'm pretty close to a solution but my inexperience with the subject matter prohibits me from getting it to work. If I'm unclear in any way please let me know. (I have a tendency of explaining things fuzzy.)

    Thanks in advance !

    [EDIT]

    I removed the duration bit because it has nothing to do with the issue. I checked the response header of the client and saw :

     Accept-Ranges:bytes
    
 Connection:keep-alive
    
 Content-Length:13232127
    
 Content-Range:bytes 0-13232127/13232128
    
 Content-Type:video/webm

    Why can't the client figure out the duration even though it receives it in the header ?

  • How to get rtp(javacv ffmpeg) stream from VLC as client

    15 avril 2015, par Sezertt

    I am trying to play rtp stream from vlc player which I created using javacv. Here is the code :

            FFmpegFrameGrabber frameGrabber = new FFmpegFrameGrabber("rtsp://10.6.0.147:554/ufirststream");
    
        frameGrabber.start();  // First I take another stream 
    

    
        FFmpegFrameRecorder frameRecorder = new FFmpegFrameRecorder("rtp://239.31.31.69:4433", frameGrabber.getImageWidth(), frameGrabber.getImageHeight());
    

    
        frameRecorder.setFormat("rtp");
    
        frameRecorder.setPixelFormat(AV_PIX_FMT_YUV420P);
    
        frameRecorder.setVideoCodec(AV_CODEC_ID_MPEG2VIDEO); <-- AV_CODEC_ID_H264
    
        frameRecorder.setFrameRate(25);           
    
        frameRecorder.setVideoBitrate(1024); <--1024*1024*2            
    
        frameRecorder.start();
    
        while (true) {
    
            frameRecorder.record(frameGrabber.grab()); //grab from stream, stream with rtp
    
        }

    If I choose my codec as AV_CODEC_ID_MPEG2VIDEO I can play the stream from VLC using rtp ://239.31.31.69:4433 with open network.

    If I increase the quality using setVideoBitrate(1024*1024*2) the stream lags too much and if I decrease the quality is so bad.

    I want to use AV_CODEC_ID_H264 as my codec to fasten things with better quality but i can’t play the stream from VLC getting error :

    SDP required A description in SDP format is required to receive the RTP stream. Note that rtp :// URIs cannot work with dynamic RTP payload format (96).

    I tried to get sdp using wireshark and then I realized rtp stream doesn’t have sdp :) so I tried to create my own sdp like this

    c=IN IP4 239.31.31.69
    
m=video 4433 RTP/AVP 96
    
a=rtpmap:96 H264/90000

    and this

    v=0
    
c=IN IP4 239.31.31.69
    
a=recvonly
    
t=0 0
    
m=video 4433 RTP/AVP 99
    
a=rtpmap:99 H264/90000
    
a=fmtp:99 packetization-mode=1;profile-level-id=42c01e;sprop-parameter sets=Z0LAHukBQHsg,aM4G4g==;

    but both seems to fail similar to this

    Can you lead me to the right direction ? What should I do to get fair quality and no lag using rtp ?

  • ffmpeg can't stream to remote client

    4 septembre 2014, par KFL

    I’m building a simple ffmpeg command line on my laptop to stream from its camera. The command line reads (verbose output at the botton) :

    host1> ffmpeg -v verbose \
    
              -f dshow \
    
              -i video="Camera":audio="Microphone" \
    
              -r 30 -g 0 -vcodec h264 -acodec libmp3lame \
    
              -tune zerolatency \
    
              -preset ultrafast \
    
              -f mpegts udp://12.34.56.78:12345

    Firstly, it works locally. I.e., I can view the output by using ffplay on the same host :

    host1> ffplay -hide_banner -v udp://12.34.56.78:12345

    Now what is NOT working is when I do this from another machine in the same network. It shows a nan progress :

    host2> ffplay -hide_banner -v udp://12.34.56.78:12345
    
    nan    :  0.000 fd=   0 aq=    0KB vq=    0KB sq=    0B f=0/0  

    I used ncat to dump the raw content. But there’s no output :

    host2>\ncat\ncat -v -u 12.34.56.78 12345
    
Ncat: Version 5.59BETA1 ( http://nmap.org/ncat )
    
Ncat: Connected to 12.34.56.78:12345.
    
(...and nothing happen...)

    Note that I can exclude firewall issues as I used ncat to communicate with each other across the wire using the same port and protocol (UDP). This works and they can chat to each other :

    host1> ncat -l -u -p 12345
    
host2> ncat -u 12.34.56.78 12345

    Any hint ?

    I’m using Windows x64 with FFMPEG 64bit installed from here. Below is the Output of my ffmpeg command :

    C:\ffmpeg\bin>ffmpeg -v verbose -f dshow -i video="Integrated Camera":audio="Microphone (Realtek High Definition Audio)" -r 30 -g 0 -vcodec h264 -acodec libmp3lame -tune zerolatency -preset ultrafast -f mpegts udp://12.34.56.78:12345
