  • Anomalie #3058 : Incohérence sur le statut de webmestre nécessaire pour désinstaller un plugin

    1er décembre 2013, par b b

    Je viens de tester sur une 3.0.13 svn et un admin peut bien désinstaller un plugin à l’aide du select en bas du formulaire de SVP.

    Il y une incohérence dans les autorisations de ce côté. On conditionne l’affichage du bouton de désinstallation unitaire au statut webmestre ici :

    http://zone.spip.org/trac/spip-zone/browser/_core_/plugins/svp/formulaires/inc-admin_plugin.html#L68

    Par contre, on ne fait aucune vérification pour l’affichage de l’item désinstaller dans le select d’action par lots. On pourrait déjà conditionner cet item du select, mais cela ne suffira pas car aucune vérification ne semble être faite dans les actions (du coup un admin un peu fourbe pourrait désinstaller un plugin en modifiant le select côté client).

  • 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
