• Upload ffmpeg file output to AWS s3 using NodeJS

  29 janvier 2020, par Durrani

  The ffmpeg.output("path/file.mp4") need a string path as an argument to write the output file to it. But s3 bucket.upload(parms, ...) need a Binary File as a value to the Body: in parms JSON

  Problem : Unable to provide file data using the file path to s3 bucket in NodeJS Environment

  FFmpeg()
  
    .input("source.mp4") //video
  
    .setStartTime(startTime)
  
    .setDuration(duration)
  
    .output(output)    //output file path: string
  
    .on("end", function() {
  
      console.log("Processing finished successfully");
  
      var params = {
  
        Bucket: process.env.S3_BUCKET,
  
        Key: "videos/filename.mp4",
  
        Body: output    //binary file data to be provided not file path
  
      };
  
      const bucket = new S3({
  
        accessKeyId: process.env.S3_ACCESS_KEY_ID,
  
        secretAccessKey: process.env.S3_SECRET_ACCESS_KEY,
  
        region: process.env.S3_REGION
  
      });
  
      bucket.upload(params, function(err, data) {
  
        console.log(err, data);
  
      });
  
    })
  
    .run();

• Fluent-ffmpeg and Multer Cut video lenght on Upload

  29 juin 2020, par jjplack

  After setup a simple upload file with Multer, I would like to cut the length and take a screenshot of the video after upload it.

  


  The upload works fine but the FFMPEG did cut the video length.

  


  First I follow the doc added the cut on setStartTime and setDuration.

  


    .setStartTime("00:00:00") 
  .setDuration("00:01:00")


  


  The video still uploaded with full length and then I tried the addInputOption and outputOptions

  


  .addInputOption("-ss 00:00:00 -t 00:01:00")
        .outputOptions([
          "-ss 00:00:00 -t 00:01:00",
        "-c:v libx264",
        "-r 30",
        "-pix_fmt yuv420p"
        ])


  


  The video still uploading with full lenght.

  


  So someone can help ?

  


  Here is the Code

  


    fastify.route({
    method: "POST",
    url: "/posts",
    //userCreateOpts,
    // schema: {
    // body: {
    // type: "object",

    // properties: {
    //video: { type: "string" },
    // title: { type: "string" }
    //}
    //}
    //},
    preValidation: [fastify.retrieveToken, fastify.retrieveUser],
    preHandler: upload.single("video"),

    handler: async function(request, reply) {
      const { Post } = fastify.sequelize;
      const { User } = fastify.sequelize;

      const user = await User.findByPk(request.user.id);

      //const fileInfo = path.parse(request.file.filename);
      const videoPath = "./public/uploads/";

      var params = {
        input: request.file.path,
        start: 0,
        duration: 1,
        output: videoPath
      };

      const proc = new ffmpeg();

      proc
        .addInput(request.file.path)

        .setStartTime("00:00:00") 
        .setDuration("00:01:00")
        //.duration("00:01.00")
        .on("start", function(ffmpegCommand) {
          /// log something maybe
        })
        .on("progress", function(data) {
          /// do stuff with progress data if you want
        })
        .on("end", function() {
          /// encoding is complete, so callback or move on at this point
        })
        .on("error", function(error) {
          /// error handling
        })
        //.addInputOption("-ss 00:00:00 -t 00:01:00")
        //.outputOptions([
        //  "-ss 00:00:00 -t 00:01:00",
        //"-c:v libx264",
        //"-r 30",
        //"-pix_fmt yuv420p"
        //])
        .output(videoPath)
        .run();

      const post = await Post.create({
        video: request.file.path,
        title: request.body.title,
        userId: user.id
    
      });
      reply.code(201).send(post);
    }
  });

  done();
};
