  • 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 (...)

  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • ffmpeg get machine readable output

    15 mai 2017, par J.S

    I am trying to find a way to get FFmpeg to return a machine readable output. basically, I just want to know if video conversion was successfull.

    I am calling FFmpeg from go code.

    output, err := exec.Command("ffmpeg", "-i", source, "-vcodec", "h264", "-acodec", "aac", "-strict", "-2", destination).CombinedOutput()

    The above code executes this command :

    ffmpeg -i /tmp/pitchVideo-1494844705-102.mp4 -vcodec h264 -acodec aac -strict -2 /tmp/1494844705.mp4

    I get the following output :

  • ffmpeg massive error spamming from FritzBox rtsp stream

    19 février 2019, par itzaiiro

    Im trying to offer a rtsp live TV stream via rtmp to my family, since the Fritz Box (which is offering the stream) has only 4 tuners -> at most 4 streams can be watched simultaneously.
    Im using ffmpeg to prepare the stream as dash stream and send it to my rtmp nginx. When i run ffmpeg im experiencing heavy image and audio artifacts in the final stream and error spams of doom in the console. I couldn’t find anything specific to my case on google. I read on the internet that AVM barely implemented the rtsp protocoll enough to get it to work with vlc mediaplayer.

    launch param :

    ffmpeg -i "rtsp://192.168.178.1:554/?avm=1&freq=114&bw=8&msys=dvbc&mtype=256qam&sr=6900&specinv=1&pids=0,16,17,18,20,260,543,544,546,548,1621" -sn -vcodec libx264 -vprofile baseline -acodec aac -strict -2 -b:v 500k -minrate 500k -maxrate 500k -bufsize 1000k -g 60 -s 640x360 -f flv rtmp://192.168.178.15/dash/pro_sieben_low -sn -vcodec libx264 -vprofile baseline -acodec aac -strict -2 -b:v 1500k -minrate 1500k -maxrate 1500k -bufsize 3000k -g 60 -s 1280x720 -f flv rtmp://192.168.178.15/dash/pro_sieben_med -sn -vcodec libx264 -vprofile baseline -acodec aac -strict -2 -b:v 5000k -minrate 5000k -maxrate 5000k -bufsize 10000k -g 60 -s 1920x1080 -f flv rtmp://192.168.178.15/dash/pro_sieben_high

    ffmpeg output (windows) :
    stored in pastebin
    https://pastebin.com/p4HAyBi5

    Is there anyway to get this under control ? The original stream is running good with vlc, but its unwatchable after its out of ffmpeg.

    Edit :
    I was running/testing this on my windows machine, but my target for this task is a ubuntu 16.04 so here ffmpeg on target with pthread support :

  • FFMPEG result video freezes in the middle of playback

    10 mai 2013, par Revoluzifer

    I'm trying stitch four source videos together into one grid. For testing purposes I'm working with a single source flv using this command :

    ffmpeg -i woohoo.flv -i woohoo.flv -i woohoo.flv -i woohoo.flv \
    
-filter_complex "[0:0]pad=iw:ih[a];[1:0]scale=w=iw/2:h=ih/2[b];
    
[2:0]scale=w=iw/2:h=ih/2[c];[3:0]scale=w=iw/2:h=ih/2[d];
    
[0:0]scale=w=iw/2:h=ih/2[e];[a][b]overlay=w[x];[x][c]overlay=0:h[y];
    
[y][d]overlay=w:h[z];[z][e]overlay=0:0" -qscale 1 stitched.avi

    The stitching itself is working great, but somehow the resulting video does not show as expected.
    After running for a few frames, it gets stuck at a single frame for most of the video, skipping the frames which should be there.

    While encoding ffmpeg throws a freaking lot of messages like :

    [Parsed_overlay_8 @ 000000000459e080] Buffer queue overflow, dropping.

    Any hints on how to solve my problem ?
    My source flv is h.264 encoded, coming from Red5 media server.

    Edit : Output is :

    root@s15757871:/opt/red5/webapps/woohoo/streams# ffmpeg -i out_3.mp4 -i 3.mp4 -filter_complex "[0:0]pad=iw:ih[a];[1:0]scale=w=iw/2:h=ih/2[b];[a][b]overlay=w:h" -vcodec libx264 -r 30 -acodec copy out_final.mp4
