  • How to Extract Frames from the uploaded video through ffmpeg using node js ?

    2 février 2021, par Aditya Vyas

    I have created application in which user uploads a video , from that video i want to extract 50 images using ffmpeg in nodejs, but i am unable to get that file after uploading it in specific folder. I am uploading video through multer as it stores video in specified folder, after that i read that video using read stream but it is not giving proper information on that particular video

    


    Code :

    


    var express = require('express');

var app = express();

var bodyParser = require('body-parser');

var path = require('path');

var multer = require('multer');

var cfenv = require('cfenv');

var watson = require('watson-developer-cloud');

var ffmpeg = require('ffmpeg');

app.use(bodyParser.json());

app.use(bodyParser.urlencoded({"extended": false}));

app.use(express.static(__dirname + '/public'));

var storage = multer.diskStorage({
    destination: function(req, file, callback){
        callback(null, './public/class'); // set the destination
    },
    filename: function(req, file, callback){
        callback(null, 199212+ '.avi'); // set the file name and extension
    }
});

var upload = multer({storage: storage});
 
 app.upload = upload;
 
 // get the app environment from Cloud Foundry
 var appEnv = cfenv.getAppEnv();

var VisualRecognitionV3 = require('watson-developer-cloud/visual-recognition/v3');

var fs = require('fs');


var visualRecognition = new VisualRecognitionV3({
  version: '2018-03-19',
  iam_apikey: 'aaIFu-fHWBXgj09eVarEQUFlIaTeH9bpgvRqHIJxu_8N'
});


app.post('/imgtable',app.upload.single('video-upl'),function(req,res){
                
    var video_file = fs.createReadStream(req.file.path);
                                    
 try {
    var process = new ffmpeg('./public/class/199212.avi');
    process.then(function (video) {
        // Video metadata
        console.log('******************************');
        console.log(video);
        // FFmpeg configuration
        console.log('*********************************');
        console.log(video.info_configuration);
    }, function (err) {
        console.log('Error: ' + err);
    });
} catch (e) {
    console.log(e.code);
    console.log(e.msg);
}

    
})

app.listen(3000);`


    


  • Can't play MP4 after download

    14 août 2018, par joe

    I am using a downloader program in Firefox to download videos playing in Firefox. Most of the time final MP4 is playable. But sometimes I get MP4 file that looks good(shows file size) but shows no length of video in file explorer.

    I get this error log.

    Could not get information from media 'ESPN 2 (HD) Live Stream Channel' from file 'C:\Download\dwHelper\ESPN 2 (HD) Live Stream Channel.mp4'. The file might be corrupted.

    [mov,mp4,m4a,3gp,3g2,mj2 @ 00000000024c3900] moov atom not found

    C :\Download\dwHelper\ESPN 2 (HD) Live Stream Channel.mp4 : Invalid data found when processing input

    It looks like moov atom is missing thus can’t aggregate PART file into final playable MP4.

    I understand that during download, PART file is created. Then later PART is aggregated into final MP4.

    So question is how can I make this MP4 to play ?
    or is it impossible to play cus moov atom was not properly downloaded ?

    Any thoughts ?
    Thanks

  • ffmpeg produces "is_avc" = false with h264_nvenc & tee muxer

    14 août 2018, par Areeb111

    I am using ffmpeg for encoding MKV (Matroska Video files) to 2x MP4 (H264 - 720p Main@L4) & (H264 - 360p Baseline@L3.1).

    Having really strange problem when using -c:v h264_nvenc and tee muxer then the produced output file is having is_avc=false even i have checked the same input matroska file with another server running with Intel QuickSync -c:v h264_qsv with the same command then the produced output file is is_avc=true.

    The main goal that i want the is_avc=true is because the files must be played using nginx-vod-module which requires the AVC video format to be streamed.

    Steps to reproduce the problem :

    • Custom ffmpeg build with NVENC support ffmpeg version N-91182-gbdf1bbd Copyright (c) 2000-2018 the FFmpeg developers   built with gcc 4.8.5 (GCC) 20150623 (Red Hat 4.8.5-28)
    • ffprobe version 4.0.2-static https://johnvansickle.com/ffmpeg/  Copyright (c) 2007-2018 the FFmpeg developers
    • Running ffmpeg command line with NVENC and tee muxer 
      /root/ffmpeg  -y -t 00:00:50 -i "testinput.mkv" -filter_complex "[0:v]split=2[s0][s1];[s0]scale=-2:720[v0];[s1]scale=-2:360[v1]" -map "[v0]" -map "[v1]" -map 0:a -c:v h264_nvenc -b:v:0 1100k -b:v:1 600k -profile:v:0 main -profile:v:1 baseline -level:v:0 4 -level:v:1 3.1 -ac 2 -c:a aac -b:a 128k -af "aresample=async=1000:first_pts=0"  -f tee "[select=\'v:0,a\']testoutput.mp4|[select=\'v:1,a\']testoutput-360.mp4"
    • Running ffprobe for the output file to check "is_avc" : 
      ./ffprobe -v quiet -print_format json -show_format -show_streams testoutput.mp4

    • My current ffprobe output results are :

      ./ffprobe -v quiet -print_format json -show_format -show_streams testoutput.mp4

    Thank you
