    Il crée des "médias", à savoir : un "média" est un article au sens SPIP créé automatiquement lors du téléversement d’un document qu’il soit audio, vidéo, image ou textuel ; un seul document ne peut être lié à un article dit "média" ;

    Afin de palier aux difficultés d’installation dues principalement aux dépendances logicielles coté serveur, un script d’installation "tout en un" en bash a été créé afin de faciliter cette étape sur un serveur doté d’une distribution Linux compatible.
    Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.

  • 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 ?

  • x264 NALUs serialization and handling

    4 février 2014, par dtumaykin

    I have my x264 encoder, producing NALUs from a raw video stream. I need to send those NALUs over the network. What is the best way of doing so ?

    Encoder is inserted into a DirectShow graph, it’s a transform filter and downstream I have the filter which handles networking. Can I pass NALUs, created by transform filter directly to network "render" filter ? Will it create some memory issues ?

    I would like to know how memory allocated for NALUs is handled inside x264 - who is responsible for freeing it ? Also I’m wondering if I can just serialize NALU to a bit stream manually and then rebuild it in the same way ?
