  • Reason for write EPIPE error in my implentation?

    18 May 2019, by Chrisl446

    So I currently have a small node.js express application for uploading images using sharp & thumbnails created from .mp4 videos using simple-thumbnail package/ffmpeg.

    The app works perfectly when uploading an image, the file is uploaded sharp processes it, then passes it along and it ends up in my amazon s3 bucket as expected. No errors what so ever.

    However, when I upload an mp4 video that I use to create and upload a thumbnail from by using simple-thumbnails genThumbnail() function, which uses ffmpeg child process, the thumbnail uploads successully to my s3 bucket, HOWEVER my app returns an EPIPE write error and NOT the url of the uploaded files url on S3.

    What is causing this and how can I fix it, considering it’s pretty much working aside from the EPIPE error that is being returned? Thanks ahead!

    The packages of concern used are as follows:

    aws-sdk

    multer

    multer-s3 <- this one with the transform option, not the standard multer-s3 package

    simple-thumbnail

    const express = require('express');
    
const app = express();
    

    
const aws = require('aws-sdk');
    
const multer = require('multer');
    
const multerS3 = require('multer-s3'); //github:gmenih341/multer-s3 version of multer-s3 with transform option
    
const sharp = require('sharp');
    
const genThumbnail = require('simple-thumbnail');
    

    
app.use((req, res, next) => {
    
    res.header('Access-Control-Allow-Origin', '*');
    
    res.header('Access-Control-Allow-Headers', 'Orgin, X-Requested-With, Content-Type, Accept, Authorization');
    
    if (req.method === 'OPTIONS') {
    
        res.header('Access-Control-Allow-Methods', 'POST');
    
        return res.status(200).json({});
    
    }
    
    next();
    
});
    

    
let uniqueFileName;
    
let s3BucketName = 'bucketname';
    

    
let s3 = new aws.S3({
    
    accessKeyId: ACCESS_KEY,
    
    secretAccessKey: SECRET_KEY,
    
    Bucket: s3BucketName
    
});

        cacheControl: 'max-age=31536000',
    
        contentType: multerS3.AUTO_CONTENT_TYPE,
    
        shouldTransform: true,
    
        transforms: [{

            key: function (req, file, cb) {
    
                uniqueFileName = Date.now().toString();
    
                cb(null, uniqueFileName + '.jpg')
    
            },
    
            transform: function (req, file, cb) {
    
                if (file.mimetype == 'video/mp4') {
    
                    //When using simple-thumbnails' getThumbnail() on an mp4 video it uploads succesfully to S3 but node returns EPIPE write error
    
                    cb(null, genThumbnail(null, null, '250x?'))
    
                } else {
    
                    //When using sharp to resize an image this works perfectly and retuns the JSON below with the files S3 URL
    
                    cb(null, sharp().jpeg())
    
                }
    

    
            }
    
        }]
    
    })
    
});
    

    
app.post('/upload', upload.array('theFile'), (req, res) => {

  • MP4Box / FFMPEG concat loses audio after first clip

    17 November 2017, by user1615343

    So I am certainly no expert when it comes to either of these tools, but I have a web-based project that’s executing commands on an Amazon Linux server to concatenate two video files that are uploaded.

    Both files are converted to mp4s first using FFMPEG, and those play perfectly in a browser after conversion:

    ffmpeg -i file1.mpg -c:v libx264 -crf 22 -c:a aac -strict -2 -movflags faststart file2.mp4

    Then, I attempt to combine these two resulting mp4s into a single mp4. I tried using FFMPEG to do this but to no avail. Switching to try MP4Box got me much closer: the videos are concatenated together, but the audio stops playing at the end of the first clip, and the second clip is silent.

    MP4Box -force-cat -keepsys -add file.mp4 -cat file2.mp4 out.mp4

    I’ve tried varying versions of the above command with no better results. Any input is greatly appreciated.

    EDIT: info on .mp4 files using

    ffmpeg -i file1.mp4 -i file2.mp4

    ffmpeg -i 1510189259715DogRunsintoGlassDoor_315a03a8e20acfc.mp4 -i

  • Reading images from AXIS ip camera using OpenCV

    14 June 2016, by batuman

    I am trying to access AXIS IP camera from my program using OpenCV.
    My OpenCV version is 3.1. I follow this tutorial link.

    I have all libraries installed.
    My following program can load mp4 video successfully. That means ffmpeg and necessary libraries are working fine.

    #include <iostream>
    
#include <opencv2></opencv2>opencv.hpp>
    

    
using namespace std;
    
int main() {
    
    cv::VideoCapture vcap("test.mp4");
    
    cv::Mat image;
    
//    const string address = "rtsp://root:pass@192.168.0.90/axis-media/media.amp?camera=1";
    
//    if(!vcap.open(address)){
    
//      std::cout &lt;&lt; "Error opening video stream or file " &lt;&lt; std::endl;
    
//      return -1;
    
//    }
    
    for(;;){
    
        if(!vcap.read(image)){
    
            std::cout &lt;&lt; "No frame" &lt;&lt; std::endl;
    
            cv::waitKey(0);
    
        }
    
        cv::imshow("Display", image);
    
        cv::waitKey(1);
    
    }
    
    return 0;
    
}
    
</iostream>

    When I tried to access the IP Camera as follow

    cv::VideoCapture vcap("rtsp://root:pass@192.168.0.90/axis-media/media.amp?camera=1");

    I have the following error

    GStreamer Plugin: Embedded video playback halted; module source reported: Could

    What could be the problem for this access to the camera?
