  • La sauvegarde automatique de canaux SPIP

    1er avril 2010, par

    Dans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.
    Pour réaliser cette tâche on se base sur deux plugins SPIP : Saveauto qui permet une sauvegarde régulière de la base de donnée sous la forme d’un dump mysql (utilisable dans phpmyadmin) mes_fichiers_2 qui permet de réaliser une archive au format zip des données importantes du site (les documents, les éléments (...)

  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

  • avformat/hls : Be more picky on extensions

    avformat/hls : Be more picky on extensions

    This blocks disallowed extensions from probing
    
It also requires all available segments to have matching extensions to the format
    
mpegts is treated independent of the extension
    

    It is recommended to set the whitelists correctly
    
instead of depending on extensions, but this should help a bit,
    
and this is easier to backport

  • Error : ffmpeg exited with code 1 on AWS Lambda

    16 juin 2022, par Hassnain Alvi

    I am using fluent-ffmpeg nodejs package to run ffmpeg for audio conversion on AWS Lambda. I am using this FFmpeg layer for lambda.&#xA;Here is my code

    &#xA;

      const bitrate64 = ffmpeg("file.mp3").audioBitrate(&#x27;64k&#x27;);&#xA;    bitrate64.outputOptions([&#xA;        &#x27;-preset slow&#x27;,&#xA;    &#x27;-g 48&#x27;,&#xA;    "-map", "0:0",&#xA;        &#x27;-hls_time 6&#x27;,&#xA;        &#x27;-master_pl_name master.m3u8&#x27;,&#xA;        &#x27;-hls_segment_filename 64k/fileSequence%d.ts&#x27;&#xA;    ])&#xA;    .output(&#x27;./64k/prog_index.m3u8&#x27;)&#xA;    .on(&#x27;progress&#x27;, function(progress) {&#xA;        console.log(&#x27;Processing 64k bitrate: &#x27; &#x2B; progress.percent &#x2B; &#x27;% done&#x27;)&#xA;    })  &#xA;    .on(&#x27;end&#x27;, function(err, stdout, stderr) {&#xA;        console.log(&#x27;Finished processing 64k bitrate!&#x27;)&#xA;    })&#xA;    .run() &#xA;

    &#xA;

    after running it via AWS lambda I get following error message

    &#xA;

    ERROR   Uncaught Exception  &#xA;{&#xA;    "errorType": "Error",&#xA;    "errorMessage": "ffmpeg exited with code 1: Conversion failed!\n",&#xA;    "stack": [&#xA;        "Error: ffmpeg exited with code 1: Conversion failed!",&#xA;        "",&#xA;        "    at ChildProcess.<anonymous> (/var/task/node_modules/fluent-ffmpeg/lib/processor.js:182:22)",&#xA;        "    at ChildProcess.emit (events.js:198:13)",&#xA;        "    at ChildProcess.EventEmitter.emit (domain.js:448:20)",&#xA;        "    at Process.ChildProcess._handle.onexit (internal/child_process.js:248:12)"&#xA;    ]&#xA;}&#xA;</anonymous>

    &#xA;

    I don't get any more info so I am not sure what's going on. Can anyone tell me what's wrong here and how can I enable more detailed logs ?

    swscale/aarch64 : add vscale specializations

    This commit adds new code paths for vscale when filterSize is 2, 4, or
    
8. By using specialized code with unrolling to match the filterSize we
    
can improve performance.
