• PHP ffmpeg output location

  18 janvier 2016, par Mick Jack

  My website allow users to upload video files to the server. Original file will be move to folder "Original" ffmpeg will compress the video and store the video in 480p folder. how to i setup ffmpeg so that it will store output of the compressed video file into original/480p ?

  Partial code of upload.php

  $target_dir = "Original/"; //where you want to upload the files to
  
  $target_file = $target_dir.basename($_FILES['file']['name']);
  
  $fileType = pathinfo($target_file, PATHINFO_EXTENSION);
  
  $newFileName = $target_dir.sha1(pathinfo(basename($_FILES['file']['name']), PATHINFO_FILENAME)).'480p'.'.'.$fileType;
  
  //$newFileName = $target_dir.sha1(pathinfo(basename($_FILES['file']['name']), PATHINFO_FILENAME)).'-'.time().'.'.$fileType;
  
  move_uploaded_file($_FILES['file']['tmp_name'], $newFileName);

  using this FFMPEG command

  shell_exec("C:\\ffmpeg\\bin\\ffmpeg.exe -y -i ".$newFileName." -c:v libx264 -s:v 854x480 -c:a copy \"480p\\{$newFileName}\" > logfile.txt 2>&1");

  i get the error
  480p\Original/ffbaf58f1231628f9ac2a583f038b51719006ec6480p.mp4 : No such file or directory

  i will like the output to be stored in original/480p/compressed-video-file

• AWS Lambda : ffmpeg thumbnails Generator : empty JPG

  3 septembre 2020, par Magikey

  When a video is uploaded on S3 i want to store a JPG screenshot.

  



  On a lambda function with amazon AWS, i do :

  



  ...

  let tmpFile = createWriteStream(`/tmp/screenshot.jpg`)

  var ffmpeg = spawn(ffmpegPath, [
      "-ss","00:00:05",
      "-i", target,
      "-vf", "thumbnail,scale=200:200", 
      "-qscale:v" ,"2",
      "-frames:v", "1",
      "-f", "image2",
      "-c:v", "mjpeg",
      "pipe:1"
    ]);

  ffmpeg.stdout.pipe(tmpFile).on("error", err => {
      console.log("Error A: ",err);
    });

  ffmpeg.on('error', err => {
    console.log("Error B", err)
    reject()
  })

  ffmpeg.on('close', code => {
    tmpFile.end();
    console.log('Log A', ffmpeg);

    child_process.exec("echo `ls -l -R /tmp`",
      (error, stdout, stderr) => {
        console.log(stdout)
    });

    resolve()
  })
...


  



  But the result is an empty JPG file in S3.

  



  Logs shows no errors, my "target" is OK, stdout ls show me the empty JPG file.

  



  I have try a lot of things, like use other version of ffmpeg but same.

  



  There is the "console.log('Log A', ffmpeg)" :
