• Invoke ffmpeg commands from javacv

  18 janvier 2016, par human123

  I am trying to build a video capture application. As a reference I am using https://github.com/sourab-sharma/TouchToRecord. In this ffmpeg commands are run from "FFmpegInvoke" class. When this project is run without any modification it is working as expected.

  But it is using older version of JavaCV. On using latest JavaCV(1.1), build fails saying that libffmpeginvoke could not be found. In "TouchToRecord" project he seems to be using libffmpeginvoke from vine.

  So my question is, can we run ffmpeg commands directly using JavaCV ? Please note that in the reference project ffmpeg commands are invoked by creating an instance of FFmpegInvoke in Processor class and command is executed from process method of Processor class.

• How to use ffmpeg.js in a ReactJS project

  1er septembre 2021, par L3M0L

  My react app is using ffmpeg.wasm (https://github.com/ffmpegwasm/ffmpeg.wasm) but because of the "recent" issues with SharedArrayBuffer I have to move the project to ffmpeg.js (https://github.com/Kagami/ffmpeg.js).

  


  Here is my problem. I installed the library (npm i ffmpeg.js) and tried to use the simple code provided on the github page for the web workers to test if it's working :

  


  const worker = new Worker("ffmpeg-worker-webm.js");
worker.onmessage = function(e) {
  const msg = e.data;
  switch (msg.type) {
  case "ready":
    worker.postMessage({type: "run", arguments: ["-version"]});
    break;
  case "stdout":
    console.log(msg.data);
    break;
  case "stderr":
    console.log(msg.data);
    break;
  case "done":
    console.log(msg.data);
    break;
  }
};


  


  but the onmessage method never get's called, instead I get

  


  GET https://localhost:3000/ffmpeg-worker-webm.js 403 (Forbidden)


  


  I'm new to the web worker topic and I could not find enough articles about this problem to wrap my head around (in fact, most of the articles use the exact same code as I do and apparently it works for them). Is the problem localhost specific or is it a ReactJS problem and I'm not able to use the ffmpeg.js library at all ? Can someone guide me on how to solve this issue ?

  


• Révision 22596 : Code mort : suppression du dernier paramètre de la fonction _image_creer_vignette...

  25 novembre 2015, par marcimat@rezo.net

  dans la fonction, qui ne servent plus a priori depuis r8673 (https://github.com/spip/SPIP/commit/9fe35bd70d028)

  $vignette valait tout le temps ’’.
  Réindentation en conséquence.

  Je ne suis pas certain que le paramètre $force non plus soit très utile.
