• FFmpegRecorder for recording Android videos from Camera

  28 novembre 2013, par Chirry

  1. I have seen the FFmpegRecorder class from FFMpeg in some files related to openCV for recording videos, specifically in FFmpegFrameRecorder class from OpenCV. How can I use this class or a similar one without using openCV ?

     As far as I have read, when you make an App using openCV, the final user will have to download some libs into his device and that is why I don't want to use OpenCV.

  2. If there is a way to make an App using openCV in which the final user don't have to download anything I would like to know it.

• spawn ENOENT error when trying to convert to mp3

  14 août 2021, par seriously

  I was trying to make a youtube video to mp3 converter using an npm package called youtube-mp3-downloader the npm documentation says I have to download FFmpeg inorder for the program to run so I did download the FFmpeg windows build. And then I added the FFmpeg binary path to the code in order to run the program and get the expected output which is the mp3 file saved to a specified location and the output data but every time I run the program I get the error spawn ../client/ffmpeg-4.4-full_build/bin ENOENT. When I research about the error I came accross that I have to install the ffmpeg and the fluent-ffmpeg dependencies to my node module and so I did but the error is still there. What am I doing wrong ? Any help is appreciated. Feel free to comment if you have any questions. Thanks in advance.

  


  


  


  var YoutubeMp3Downloader = require("youtube-mp3-downloader");

//Configure YoutubeMp3Downloader with your settings
var YD = new YoutubeMp3Downloader({
  // FFmpeg binary location *Where the error is arising
  "ffmpegPath": "../client/ffmpeg-4.4-full_build/bin",
  // Output file location (default: the home directory)
  "outputPath": "../client/audio",
  // Desired video quality (default: highestaudio)
  "youtubeVideoQuality": "highestaudio",
  "queueParallelism": 2, // Download parallelism (default: 1)
  // Interval in ms for the progress reports (default: 1000)
  "progressTimeout": 2000,
  "allowWebm": false // Enable download from WebM sources (default: false)
});

//Download video and save as MP3 file
YD.download("Vhd6Kc4TZls");

YD.on("finished", function(err, data) {
  console.log(JSON.stringify(data));
});

YD.on("error", function(error) {
  console.log(error);
});

YD.on("progress", function(progress) {
  console.log(JSON.stringify(progress));
});

  


  


  



• Read Output in Batch

  29 septembre 2016, par arielbeje

  I am using this code to try and download a video+subtitles using youtube-dl and then combine them using ffmpeg.

  I am trying to set the video/subtitle output to title.extension instead of the regular title id.extesion, but to do that youtube-dl has a command that outputs it like an echo command, so I need to read it.

  @echo off
  
  echo Write a link and press enter
  
  set /p link=
  
  cls
  
  
  
  youtube-dl.exe -u myusername -p mypassword --skip-download --sub-lang enUS --sub-format "ass" --output "%(uploader)s%(title)s.%(ext)s" "%link%"
  
  youtube-dl.exe -u myusername -p mypassword -f worst --ffmpeg-location "%cd%\ffmpeg.exe" --hls-prefer-ffmpeg --console-title --output "%(uploader)s%(title)s.%(ext)s" "%link%"
  
  
  
  youtube-dl.exe -u myusername -p mypassword --skip-download --get-title "%link%" > title.txt
  
  for /f "delims=" %%x in (title.txt) do set title=%%x
  
  ffmpeg.exe -i "%cd%\%title%.flv" -vf "ass=%cd%\%title%.ass" "%cd%\%title%.mkv"
