Context

I'm trying to develop a service that puts watermark on videos. I have the logo locally on the server. I'm guaranteed that the videos will be mp4 and I must return mp4 as well.

Code to reproduce

app.post('/upload', (req, res, next) => {
  const form = new multiparty.Form();

  form.parse(req, function(err, fields, files) {});
  form.on('file', function(name, file) {
    const inputStream = fs.createReadStream(file.path);

    ffmpeg(inputStream)
      .inputFormat('mp4')
      .input('./logo.png')
      .complexFilter(['overlay=10:10'])
      .videoCodec('libx264')
      .outputFormat('mp4')
      .outputOptions('-movflags frag_keyframe+empty_moov')
      .on('start', commandLine => {
        console.log('Spawned Ffmpeg with command: ' + commandLine);
      })
      .on('progress', progress => {
        console.log('Processing: ' + progress.percent + '% done');
      })
      .on('error', (err, stdout, stderr) => {
        console.error(stderr, err);
      })
      .pipe(res, { end: true });
  });
});

Error

P. S.

I have also tried using local mp4 video to generate the input stream like so:

    const inputStream = fs.createReadStream('./dummy-video.mp4');

P. P. S.

The .videoCodec() and .outputOptions() lines are from similarly sounding issues I have found in this repo. They are NOT part of my requirements.

P. P. P. S.

Running the command ffmpeg -i video.mp4 -i logo.png -filter_complex "overlay=10:10" output.mp4 in the terminal successfully sets the watermark.

s3 bucket signed url is not working its showing 'No such file or directory'

[viktorstaikov]

Hi,

The url itself is valid and I can open the video there. Where did you see this s3 error?

[ahmed-sharief5]

Please refer this url https://stackoverflow.com/questions/51946375/ffmpeg-for-aws-s3-bucket-signed-url-not-working-in-node-js
