• Encode multiple files from the same Folder with Google Colab & FFmpeg

  16 août 2021, par Ptibouc77

  i made a Google colab to encode my videos, but actually i can only do files on by one.
I want to encode all video files from the same folder.

  


  I tried this but didn't seem to works

  


      import os

DIRECTORY= '/content/drive/My Drive/Videos'
for filename in os.listdir(DIRECTORY):
    if (filename.endswith(".mov")): #or .avi, .mpeg, whatever.
        os.system("ffmpeg -i {0} -c:v libx265 -crf 26 -c:a aac -b:a 160k output%d.mp4".format(filename))
        print(filename)


  


  Edit : I edited the FFmpeg command but still not workings on Google Colab.
Edit 2 : Print command only return the name of the files with the extension like "MyMovie.mov" how do i put the full path to the ffmpeg command ? I also want to put the ouput files to a subfolder named x265

  


• 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'
        });
});

        }
