  • Support de tous types de médias

    10 avril 2011

    Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

  • Supporting all media types

    13 avril 2011, par

    Unlike most software and media-sharing platforms, MediaSPIP aims to manage as many different media types as possible. The following are just a few examples from an ever-expanding list of supported formats : images : png, gif, jpg, bmp and more audio : MP3, Ogg, Wav and more video : AVI, MP4, OGV, mpg, mov, wmv and more text, code and other data : OpenOffice, Microsoft Office (Word, PowerPoint, Excel), web (html, CSS), LaTeX, Google Earth and (...)

  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

  • 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

  • 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

  • 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);

        console.log('*********************************');
        console.log(video.info_configuration);
    }, function (err) {
        console.log('Error: ' + err);
    });
} catch (e) {
