• OpenBR installation on ubuntu fails

  5 juillet 2014, par ikassi

  I am following this guide to install OpenBR on a fresh Ubuntu 13.10 x64 installation :

  http://openbiometrics.org/doxygen/latest/linux_gcc.html

  The process keeps failing at the make -j4 step when installing openCV returning :

  Linking CXX static library ../lib/libIlmImf.a
  
  [ 27%] Built target IlmImf
  
  make: *** [all] Error 2

  I have also tried this guide with no success.

  Can someone please tell me how to fix this ?

• sent file using axios using passthrough stream module in nodejs

  12 août 2022, par Harikrushna Patel

  Imports

  


  const ffmpegPath = require('@ffmpeg-installer/ffmpeg').path;
const FfmpegCommand = require('fluent-ffmpeg');
const fs = require('fs');
const path = require('path');
const streamNode = require('stream');
const FormData = require('form-data');
const axios = require('axios').default;


  


  Code here

  


  async function audios() {
  let stream = fs.createReadStream(path.join(__dirname, '../videos/video.mp4'));
  let writeStream = fs.createWriteStream(path.join(__dirname, '../response/audios/' + +new Date() + '.wav'));
  let pass = new streamNode.PassThrough();
  let outputFile = path.join(__dirname, '../response/audios/' + +new Date() + '.wav');
  const ffmpeg = FfmpegCommand(file);

  ffmpeg
    .setFfmpegPath(ffmpegPath)
    .format('mp4')
    .toFormat('wav')
    .on('end', function () {
      console.log('file has been converted successfully');
    })
    .on('error', function (err, stdout, stderr) {
      console.log('an error happened: ' + err.message);
      console.log('ffmpeg stdout: ' + stdout);
      console.log('ffmpeg stderr: ' + stderr);
    })
    .on('end', function() {
      console.log('Processing finished !');
    })
    .stream(pass, { end: false })
    var bodyFormData = new FormData();
    bodyFormData.append('file', pass);
    let headers = bodyFormData.getHeaders(); 

    try {
      const jdata = await axios.post('http://localhost:4080/video',bodyFormData, {    maxContentLength: Infinity,
      maxBodyLength: Infinity,validateStatus: (status) => true ,headers:headers });
      console.log(jdata.data);
    } catch (error) {
      console.log("error" ,error.message);
    }

}


  


  I am getting errors to sent passthrough stream through formdata ;
issue is ffmpeg not creating readstrem so I am created passthrough from it and passed in formdata but not working right now

  


• Stripping 'actual time of day' from AVI files

  22 avril 2014, par wxJunkie

  I have TB’s of AVI|DV|VOB files. I want to run a script that will enable me to find the real start time + end time AND the navigation (latitude & longitude) that is embedded in the audio of each of the clips that I have and export the list perhaps to a .txt or .doc list. I use a SMPTE reader now that can read the time that is embedded in the video, so there has to be a script that will pull those certain criteria’s out ?

  I have ran several codes in the past that has given me :
  duration : 00:01:23.83 start : 0.0000000, bitrate 28771 kb/s etc.
  I always get ’start : 0.0000000’ for each clip and I need the real start time of each clip.

  Is this possible ?
