• Im getting error when generating thumbnails using ffmpeg in firebase functions

  5 juillet 2020, par Sajjad

  I'm writing this code for generating thumbnail from a video uploaded to firebase storage using FFmpeg, I am saving thumbnails first in the temp directory and then uploading it to firebase storage. The thumbnails are saved in temp dir but I'm getting an error while saving it to firebase storage. (EISDIR ERROR)

  


  const targetTempFilePath = path.join(os.tmpdir(), targetTempFileName);
const targetStorageFilePath = path.join(path.dirname(filePath), targetTempFileName);
ffmpeg.ffprobe(req.body.videoUrl, (err, metaData) => {
    if (err) {
      console.log(err);
    }

    fileDuration = metaData.format.duration;
  });

  ffmpeg(req.body.videoUrl)
    .on("filenames", (filenames) => {
      console.log("Will generate " + filenames.join(", "));
      thumbsFileUrl = "" })
    .on("end", () => {
      console.log(targetTempFilePath);
      admin
        .storage()
        .bucket()
        .upload(targetTempFilePath, {
          destination: targetStorageFilePath,
        })
        .then(() => {
          console.log("Output audio uploaded to", targetStorageFilePath);
          // fs.unlinkSync(tempLocalFile);
          return res.status(200).json({
            success: true,
            thumbsFileUrl: thumbsFileUrl,
            fileDuration: fileDuration,
          });
        })
        .catch((err) => {
          console.log(err);
          return res.json({ success: false });
        });
    })

    .screenshots({
      // Will take screens at 20%, 40%, 60% and 80% of the video
      count: 2,
      folder: targetTempFilePath,
    });

  I've tried added user root at the top of file, exec_push, exec_static, exec ffmpeg, exec /usr/bin/ffmpeg and also write script file still not
working

  


  ff.sh files

  


  echo "running script";
ffmpeg -re -i http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4 -c:v libx264 -preset veryfast -maxrate 3000k -bufsize 6000k -pix_fmt yuv420p -g 50 -c:a aac -b:a 160k -ac 2 -ar 44100 -f flv rtmp://127.0.0.1/hls/my_video;

• How to access uploaded file from multer ?

  13 avril 2017, par Somename

  Im able to upload an image to S3. Now, if the file selected is .gif, I want to be able to convert the .gif file to .mp4 and upload the converted file to S3. I am able to convert a .gif to .mp4 with ffmpeg only if I give the path of the file. How do I access the uploaded file from Multer ? Below is my code :

  var express = require('express');
  
  var bodyParser = require('body-parser');
  
  var app = express();
  
  var aws = require('aws-sdk');
  
  var multer = require('multer');
  
  var multerS3 = require('multer-s3');
  
  var s3 = new aws.S3();
  
  var ffmpeg = require('fluent-ffmpeg');
  
  
  
  
  
  var upload = multer({
  
      storage: multerS3({
  
          s3: s3,
  
          bucket: 'myBucket',
  
          key: function (req, file, cb) {
  
              console.log(file);
  
              var extension = file.originalname.substring(file.originalname.lastIndexOf('.')+1).toLowerCase();
  
  
  
                  if(extension=="gif"){
  
                  console.log("Uploaded a .gif file");
  
  
  
                  ffmpeg(file) //THIS IS NOT WORKING
  
                      .setFfmpegPath("C:\\ffmpeg\\bin\\ffmpeg.exe")
  
                        .output('./outputs/2.mp4')    //TRYING TO UPLOAD LOCALLY, WHICH FAILS
  
                        .on('end', function() {
  
                          console.log('Finished processing');
  
                        })
  
                        .run();
  
              }
  
  
  
              cb(null, filename);
  
          }
  
      })
  
  });

  I’m trying to access the uploaded file like this : ffmpeg(file) since file is an argument passed in the multer function.

  My form :

  <form action="/upload" method="post" enctype="multipart/form-data">
  
      <input type="file" /> <br />
  
      <input type="submit" value="Upload" />
  
  </form>

  In which part of the process do I convert the file ?

  Please help. Many thanks.
