  • Les tâches Cron régulières de la ferme

    1er décembre 2010, par

    La gestion de la ferme passe par l’exécution à intervalle régulier de plusieurs tâches répétitives dites Cron.
    Le super Cron (gestion_mutu_super_cron)
    Cette tâche, planifiée chaque minute, a pour simple effet d’appeler le Cron de l’ensemble des instances de la mutualisation régulièrement. Couplée avec un Cron système sur le site central de la mutualisation, cela permet de simplement générer des visites régulières sur les différents sites et éviter que les tâches des sites peu visités soient trop (...)

    I’m trying to use ffmpeg for streaming directly from camera to mobile through wifi.So i would like increase the bit rate as 10Mbps for 720p.Is it possible do using ffmpeg ?
    When I tried to increase the bitrate I’m facing the following issue : "Segmentation fault5" the below is my command log :

  • Raspberry Pi > CRTMPServer > JWplayer

    18 juin 2015, par user3147697

    I’m trying to get a raspberry pi to stream to a crtmpserver, and from there to a webpage with JWplayer.

    I am able to send video successfully to crtmpserver with this :

    raspivid -t 0 -w 960 -h 540 -fps 25 -b 500000 -vf -o - | ffmpeg -i - -acodec aac -ac 2 -strict experimental -ab 160k -vcodec libx264 -preset slow -profile:v baseline -level 30 -maxrate 10000000 -bufsize 10000000 -b 1000k -f rtsp -metadata title=teststream rtsp ://192.168.1.20:5544/flvplayback

    But am having trouble viewing the stream from crtmpserver using this is my html jwplayer code :

    <code class="echappe-js">&lt;script type=&quot;text/javascript&quot;&gt;<br />
    
    jwplayer(&quot;myElement-teststream&quot;).setup({<br />
    
        playlist: [{<br />
    
            sources:[{<br />
    
                file: 'rmtp://192.168.1.20:1935/live/teststream&quot;<br />
    
            }]<br />
    
        }],<br />
    
        height: 1080,<br />
    
        primary: 'flash',<br />
    
        width: 1920<br />
    
    });<br />
    
    &lt;/script&gt;

    What am I missing ?

    19 février 2024, par haijia

    I want make a music player use ffmpeg. As usual, when read the end of file, the av_read_frame will sender a NULL AVPacket to flash packet.NULL AVPacket But when I use the flac format file, the avcodec_receive_frame get the error is "Invalid data found when processing input" instead of "end of file".receive_frame_error,But on other format, avcodec_receive_frame get the error called "end of file".&#xA;So, Shoud I ignore this error and regard as the end of file ?

    &#xA;

    If possible, I want it get "end of file".
