  lavu : add an API function to return the Libav version string
  This returns something like "v12_dev0-1332-g333a27c". This is much more
  
  useful than the individual library versions, of which there are too
  
  many, and which are very hard to map back to releases or git commits.

• avutil/avstring : support input path as a null pointer or empty string

  avutil/avstring : support input path as a null pointer or empty string
  Linux and OSX systems support basename and dirname via <libgen.h>, I plan to
  
  make the wrapper interface conform to the standard interface first.
  
  If it is feasible, I will continue to modify it to call the system interface
  
  if there is already a system call interface.
  You can get more description about the system interface by below command :
  
   "man 3 basename"

• String is showing undefined

  30 octobre 2022, par Lol

  I am trying to create video using ffmpeg and returning its path to index.js but path is showing undefined.

  


  index.js

  


  app.get('/content/:myfact', async (req, res) => {
  let myfactdata = req.params.myfact;
  let myfact = myfactdata.replace("_", " ");
  const video = await generateVideo(myfact);
  console.log(video)
});


  


  This is my contentVideo.js

  


  const generateImage = require('./contentimage.js');
const { spawn } = require('child_process');

const generateVideo = async (myfact) => {
  await generateImage(myfact);
  const child = spawn('ffmpeg', [
    '-i', 'pictures/download/image.png', 'pictures/download/video.mp4'
  ]);
  child.on('close', function (code, signal) {
    const video = 'pictures/download/video.mp4'
    return video
  });
}

module.exports = generateVideo
