  • D’autres logiciels intéressants

    12 avril 2011, par

    On ne revendique pas d’être les seuls à faire ce que l’on fait ... et on ne revendique surtout pas d’être les meilleurs non plus ... Ce que l’on fait, on essaie juste de le faire bien, et de mieux en mieux...
    La liste suivante correspond à des logiciels qui tendent peu ou prou à faire comme MediaSPIP ou que MediaSPIP tente peu ou prou à faire pareil, peu importe ...
    On ne les connais pas, on ne les a pas essayé, mais vous pouvez peut être y jeter un coup d’oeil.

  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • Encoded mp4 video won't play in Firefox v33

    3 novembre 2014, par Michael Heuberger

    When this video is encoded with the following ffmpeg command, it cannot be played in Firefox v33 (a blank screen appears). But when I play it in the native VLC player, it works. So here the long ffmpeg command :

    $ ffmpeg -r 15 -f image2 -i /home/(...)/frames/%d.jpg -i
    
  /home/(...)/preview.wav -y -acodec libfdk_aac -b:a 128k 
    
  -vcodec libx264 -b:v 386k -preset ultrafast -profile:v baseline 
    
  -crf 6 -pix_fmt yuv420p -loglevel warning -movflags faststart 
    
  /home/(...)/preview.mp4

    As you can see, preview.mp4 is encoded by a sequence of jpg images with a given wav file.

    The ffmpeg output is just this

    [wav @ 0x35ff460] Estimating duration from bitrate, this may be inaccurate
    
Guessed Channel Layout for  Input Stream #1.0 : mono
    
[swscaler @ 0x35f0d80] deprecated pixel format used, make sure you did set range correctly

    Any clues why it won’t play on Firefox (and what the other ffpmeg warnings mean) ?

    Thanks !!!

  • fluent-ffmpeg throw er when concatenate videos

    2 mai 2020, par Romualdo Arrechea Hernández

    I'm using fluent-ffmpeg version 2.1.2.
When I execute the current code the output show off a error message :

    



    var ffmpeg = require('fluent-ffmpeg');
var glob= require('glob');
ffmpeg.setFfmpegPath("/usr/bin/ffmpeg");
ffmpeg.setFfprobePath("/usr/bin/ffprobe");
var command = ffmpeg();

const path='/home/username/somefolder/*/output.mp4';

var videos=glob.sync(path);
var output="./output.mp4";
videos.map(video=>command.addInput(video));
command.mergeToFile(output);


    



    the console output>

    



    **events.js:287&#xA;      throw er; // Unhandled &#x27;error&#x27; event&#xA;      ^&#xA;&#xA;Error: ffmpeg exited with code 1: Conversion failed!&#xA;&#xA;    at ChildProcess.<anonymous> (/home/r/Projects/prueba/node_modules/fluent-ffmpeg/lib/processor.js:182:22)&#xA;    at ChildProcess.emit (events.js:310:20)&#xA;    at Process.ChildProcess._handle.onexit (internal/child_process.js:275:12)&#xA;Emitted &#x27;error&#x27; event on FfmpegCommand instance at:&#xA;    at emitEnd (/home/r/Projects/prueba/node_modules/fluent-ffmpeg/lib/processor.js:424:16)&#xA;    at endCB (/home/r/Projects/prueba/node_modules/fluent-ffmpeg/lib/processor.js:544:13)&#xA;    at handleExit (/home/r/Projects/prueba/node_modules/fluent-ffmpeg/lib/processor.js:170:11)&#xA;    at ChildProcess.<anonymous> (/home/r/Projects/prueba/node_modules/fluent-ffmpeg/lib/processor.js:182:11)&#xA;    at ChildProcess.emit (events.js:310:20)&#xA;    at Process.ChildProcess._handle.onexit (internal/child_process.js:275:12)**&#xA;</anonymous></anonymous>

    The video should be created, but it's unable to concat. Some clue ?

  • Node-Fluent-ffmpeg stops with Error initializing complex filters. Invalid argument

    28 août 2020, par V.Panichkin

    I use node-fluent-ffmpeg to generate ffmpeg command. I created a node.js app, but it throws an exception :

    &#xA;

    Error: ffmpeg exited with code 1: Error initializing complex filters.&#xA;Invalid argument&#xA;&#xA;    at ChildProcess.<anonymous> (/home/victor/Documents/work/recorder_ws/node_modules/fluent-ffmpeg/lib/processor.js:182:22)&#xA;    at ChildProcess.emit (events.js:315:20)&#xA;    at Process.ChildProcess._handle.onexit (internal/child_process.js:275:12)&#xA;</anonymous>

    &#xA;

    The command that was generated by Node-Fluent-Ffmpeg is

    &#xA;

    ffmpeg -i /home/user/videos/1.webm -i /home/user/videos/3.webm -i /home/user/videos/4.webm -i /home/user/videos/5.webm -y -filter_complex "[0:v] scale=qvga [a0];[1:v] scale=qvga [a1];[2:v] scale=qvga [a2];[3:v] scale=qvga [a3];[a0][a1][a2][a3]xstack=inputs=4:layout=0_0|w0_0|0_h0|w0_h0[out]" -map "[out]" -c:v libx264 -t &#x27;30&#x27;  ./server-generated.mkv&#xA;

    &#xA;

    I checked it several times and didn't find any problem. Afterwards, I run this generated command directly in the console and it works fine.

    &#xA;

    Could someone tell me why node-fluent-ffmpeg cannot run this command with a valid ffmpeg command and throws invalid argument exception ?

    &#xA;
