• possible C code implementation ideas for a given shell script(related to ffmpeg)

  21 août 2011, par Ted

  The shell script i'm trying to implement goes like this,

      #!/bin/bash
  
      while [ 1 ]
  
      do
  
         nc -l 1234 | ffmpeg -i pipe:0 -vcodec mpeg4 -s qcif -f m4v -y pipe:1 | nc localhost 1235
  
      done 

  what it does is to simply take in a stream of video input through network and do live video transcoding(with ffmpeg of course !) and streaming back the video through the net. my question is how should i go by to implement this functionality in a clean C code. i know i can use popen() to pipe such a command from a c code but i would like to do better. may be with sockets and staff... any pointers are appreciated.

  Fixing display size setting problem.

  Fix of https://code.google.com/p/webm/issues/detail?id=608. We could have
  used invalid display size equal to the previous frame size (not to the
  current frame size).

  var ffmpeg = require('fluent-ffmpeg');
var axios = require('axios');

// make sure you set the correct path to your video file

var proc = ffmpeg('./input.mp4')
    .videoFilters({
  filter: 'drawtext',
  options: {
    fontfile:'font.ttf',
    text: 'THIS IS TEXT',
    fontsize: 20,
    fontcolor: 'white',
    x: '(main_w/2-text_w/2)',
    y: 50,
    shadowcolor: 'black',
    shadowx: 2,
    shadowy: 2
  }
})
    .input('https://verse.mp3quran.net/arabic/shaik_abu_baker_alshatri/64/001002.mp3')
    .on('end', function () {
        console.log('file has been converted succesfully');
    })
    .on('error', function (err) {
        console.log('an error happened: ' + err.message);
    })
    // save to file
    .save('./out.mp4');
