• How to convert image to video using fluent-ffmpeg in NodeJS

  2 juillet 2022, par MjM

  I would like to create a video using fluent-ffmpeg in NodeJS. My objective is to create a video using one image. And what I have done so far is the following :

  



  var express = require('express')
var router = express.Router()

const ffmpeg = require('fluent-ffmpeg');

router.get('/test', function (req, res) {
    // make sure you set the correct path to your video file
    var proc = ffmpeg('http://localhost:3000/images/image.jpg')

        // loop for 5 seconds
        .loop(5)
        // using 25 fps
        .fps(25)
        // setup event handlers
        .on('end', function () {
            console.log('file has been converted succesfully');
        })
        .on('error', function (err) {
            console.log('an error happened: ' + err.message);
            console.log(' error code is : ' + err.code);
        })
        // save to file
        .save('http://localhost:3000/video/image-cdo.mp4');
})

module.exports = router;


  



  When I run this I have been getting the following result with an error :

 for output file #0 (incorrect codec parameters ?) : Invalid argument

 Conversion failed !

  



   error code is : undefined

  I have the above code that can successfully generate a 5s video in my local Mac.

  However, when I push the code to the production Ubuntu, it can only generate a 1s video only.

  There is no error in the Ubuntu side. I wonder if I missed anything.

  I also wonder should I preload the source images first ?

• avformat/matroskaenc : Fix memleak upon failure

  16 octobre 2019, par Andreas Rheinhardt

  avformat/matroskaenc : Fix memleak upon failure
  The Matroska muxer up until now leaked memory in two scenarios :
  1. If an error happened during writing the trailer, as
  
  mkv_write_trailer() returned early without cleaning up.
  
  2. If mkv_write_header() indicated success despite an error in the
  
  underlying AVIOContext. In this case avformat_write_header() returned
  
  the IO error and according to the API the caller is not allowed to call
  
  av_write_trailer(), so that no cleanup happened for the allocations made
  
  in mkv_write_header().
  This has been fixed by using a dedicated deinit function.
