• Is it possible to convert all video files in subdirectories on google drive using ffmpeg & rclone ?

  24 avril 2020, par rms

  Currently I'm using this code whereby rclone fetches 1 file from my google drive, converts it using ffpmeg on a server and moves the converted files to the same folder. It's shown as below.
Step 1 is generating a list over which rclone can iterate over and the conversion process begins with the second script in step 2

  



  step 1

  



  rclone lsf "gdrive:/folder" --files-only > list.txt


  



  step 2

  



  while read file; do
    rclone copy "gdrive:/folder/""$file" . -P
    ffmpeg -i "$file" -vf scale=-1:540 -vcodec libx265 -crf 26 "${file%.*}.mkv" null
    rm -f "$file"
    rclone move . "gdrive:/folder/" --exclude list.txt -P
done code>

  



  However, some sub directories have nested videos to convert which would rather take a long time if I'm to do it for every folder. This brought me to my question whether it's possible to modify the above process to work with subdirectories.

  



  I've tried rclone lsf to generate the list recursively using the -R flag but ffmpeg doesn't seem to read the file from the list to make it work. Is there a way to make this work with some tweaking possibly ?

  


• Upload screenshots to google cloud storage bucket with Fluent-ffmpeg

  2 janvier 2021, par aarpods

  I am currently using multer to upload videos to my google storage bucket, and fluent-ffmpeg to capture thumbnails of the videos. Videos are being uploaded into the buckets correctly, but not the thumbnails from ffmpeg. How can I change the location of the thumbnails to my google storage bucket ?

  


  Back-End Video upload

  


  require ('dotenv').config()
const express = require('express');
const router = express.Router();
const multer = require("multer");
var ffmpeg = require('fluent-ffmpeg');
const multerGoogleStorage = require('multer-google-storage');
const { Video } = require("../models/Video");
const {User} = require("../models/User")
const { auth } = require("../middleware/auth");


var storage = multer({
    destination: function (req, file, cb) {
        cb(null, 'videos/')
    },
    filename: function (req, file, cb) {
        cb(null, `${Date.now()}_${file.originalname}`)
    },
    fileFilter: (req, file, cb) => {
        const ext = path.extname(file.originalname)
        if (ext !== '.mp4' || ext !== '.mov' || ext !== '.m3u' || ext !== '.flv' || ext !== '.avi' || ext !== '.mkv') {
            return cb(res.status(400).end('Error only videos can be uploaded'), false);
        }
        cb(null,true)
    }
})
// Set location to google storage bucket
var upload = multer({ storage: multerGoogleStorage.storageEngine() }).single("file")

router.post("/uploadfiles", (req, res) => {

    upload(req, res, err => {
        if (err) {
            return res.json({sucess: false, err})
        }
        return res.json({ success: true, filePath: res.req.file.path, fileName: res.req.file.filename})
    })
});


  


  Back-end thumbnail upload

  


  router.post("/thumbnail", (req, res) => {

    let thumbsFilePath = "";
    let fileDuration = "";

    ffmpeg.ffprobe(req.body.filePath, function (err, metadata) {
        console.dir(metadata);
        console.log(metadata.format.duration);

        fileDuration = metadata.format.duration;
    })


    ffmpeg(req.body.filePath)
        .on('filenames', function (filenames) {
            console.log('Will generate ' + filenames.join(', '))
            thumbsFilePath = "thumbnails/" + filenames[0];
        })
        .on('end', function () {
            console.log('Screenshots taken');
            return res.json({ success: true, thumbsFilePath: thumbsFilePath, fileDuration: fileDuration })
        })
        //Can this be uploaded to google storage?
        .screenshots({
            // Will take 3 screenshots
            count: 3,
            folder: '/thumbnails/',
            size: '320x240',
            //Names file w/o extension
            filename:'thumbnail-%b.png'
        });
});


  


  Front-end video upload

  


   const onDrop = (files) => {
        let formData = new FormData();
        const config = {
            header: {'content-type': 'multipart/form-data'}
        }
        console.log(files)
        formData.append("file", files[0])

        axios.post('/api/video/uploadfiles', formData, config)
            .then(response => {
                if (response.data.success) {
                    let variable = {
                        filePath: response.data.filePath,
                        fileName: response.data.fileName
                    }
                    setFilePath(response.data.filePath)

                    //Thumbnail
                    axios.post('/api/video/thumbnail', variable)
                        .then(response => {
                            if (response.data.success) {

                                alert("Failed to generate a thumbnail");
                            }
                        })

                } else {
                    alert('Failed to save video to the server')
                }
            })
