  • 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 (...)

  • Mise à disposition des fichiers

  • Android YouTube Live v3 rtmp streaming via ffmpeg won't show preview

    14 décembre 2017, par Ariel Yust

    Hi everyone I’m breaking my head over this issue here,
    I’m developing an Android App for streaming content from the user’s device camera (back/front) to a live streaming on YouTube.

    Problem :
    YouTube Live shows "The health is good." in (Live Streaming->Events) but there’s nothing showing in the preview... in fact when I press play it tells me "An error has occurred, please try again later".

    Why is this happening ? what could be the problem ?

    What I’m doing :
    using google’s Oauth 2.0 and google api for login.
    YouTube V3 data api’s for creating a new broadcast and stream or use an opened stream - I’m using RTMP.

    I’m opening Camera Api1 and capturing the video into a SurfaceTexture, then I encode images and audio (MIC) using Android’s MediaCodec, save a 3+- seconds *.mp4 file locally and then once the muxer is done I stream the file with ffpmeg.

    String[] cmd = {
    
            "-i", filePath, //local file path (video is playable with vlc)
    
            "-strict", "experimental",
    
            "-acodec", "aac",
    
            "-ac", "1",
    
            "-ar", "44100",
    
            "-vcodec", "libx264",
    
            "-pix_fmt", "yuv420p",
    
            "-r", "30",
    
            "-g", "60",
    
            "-vb", "512k",
    
            "-profile:v", "main",
    
            "-preset", "medium",
    
            "-f", "flv",
    
            "-s", "1280x720",
    
            CreateBroadcast.rtmpUrl
    
        };
    

    
ffmpeg.execute(cmd, responseHandler); //responseHandler notify me to send next file
    

    
//how I set a new rtmpUrl, in CreateBroadcast.java
    
rtmpUrl = 
    
    returnedStream.getCdn().getIngestionInfo().getIngestionAddress() +
    
    File.separator + 
    
    returnedStream.getCdn().getIngestionInfo().getStreamName();

  • FFMPEG ALSA xrun crash

    13 décembre 2017, par Liam Martens

    I’m running a YouTube RTMP stream using FFMPEG with x11grab and an alsa loopback device but sometimes after let’s say 20 hours there is an ALSA xrun and then the ffmpeg command crashes, but I’m not sure why or how this happens. (mind you the ffmpeg command does not run continuously it gets restarted automatically every so often, but the xrun makes the command crash causing the stream to go offline sometimes because a crash restart is not fast enough)

    I’m using thread_queue_size and I’ve even manually compiled ffmpeg with a higher ALSA BUFFER SIZE, but the issue appears to persist still. Besides this I’ve also scoured many posts with people having similar issues but these never really seem to end up resolved.

    This is the stream command

    ffmpeg -loglevel verbose -f alsa -thread_queue_size 12288 -ac 2 -i hw:Loopback,1,0 \
    
         -probesize 10M -f x11grab -field_order tt -thread_queue_size 12288 -video_size 1280x720 -r 30 -i :1.1 \

  • Hikvision NVR video conversion ffmpeg

    6 août 2024, par astralmaster

    I have a Hikvision NVR that stores security camera footage that I need to display on a website. I know that Hikvision uses proprietary H.264 codec that makes it impossible to play (coherently) in popular video players, like VLC, unless you install that codec everywhere you play it.

    &#xA;&#xA;

    My plan was to transcode the video using ffmpeg to regular H.264 codec and AAC for audio but the produced file has the same issues as the original - no audio when playing and very disruptive video. &#xA;So the question is, does ffmpeg support encoding from Hikvision video/audio codecs ? Or perhaps should try to convert to different web-capable codecs using ffmpeg ?&#xA;My ffmpeg command looks like this :

    &#xA;&#xA;

    ffmpeg -i C:\1.mp4  -c:v libx264 -preset fast -crf 30 -b:v 200k -c:a aac -strict experimental -movflags faststart -threads 0 C:\2.mp4&#xA;

    &#xA;&#xA;

    EDIT : What's interesting is that ffplay.exe opens and plays the original video files with no problem whatsoever, even on a computer where Hikvision codecs are not isntalled, therefore I figured conversion should be possible as well ?

    &#xA;&#xA;

    Mediainfo output of the video file in question :
