  25 février 2021, par Дмитрий Бондаренко

  I need microservice (converter audio using streams), but have problem with ffmpeg

  


  my test ffmpeg

  


  package codec

import (
    "bytes"
    "os"
    "os/exec"
    "testing"
)

func Test1(t *testing.T) {
    in, err := os.Open("/mp4-mp3/src.m4a")
    if err != nil {
        t.Fatal(err.Error())
    }
    out, err := os.OpenFile("/mp4-mp3/out.mp3", os.O_RDWR|os.O_CREATE, 0666)
    if err != nil {
        t.Fatal(err.Error())
    }
    cmd := exec.Command(
        "ffmpeg",
        "-f", "m4a",
        "-i", "pipe:0",
        "-f", "mp3",
        "pipe:1")

    cmd.Stdin = in
    cmd.Stdout = out
    stderr := &bytes.Buffer{}
    cmd.Stderr = stderr
    if err := cmd.Run(); err != nil {
        t.Logf(stderr.String())
        t.Fatal(err.Error())
    }

}

  How to properly set ffmpeg parameters to convert from stream to stream ?

  


• Getting error while deploying application with node-media-serve module and ffmpeg buildpack in heroku

  16 septembre 2020, par Anurag Gautam

  I have created a MERN app with video streaming by using node-media-serve module, with following configuration

  


  trans: {
  ffmpeg: '/vendor/ffmpeg',
   tasks: [] ,
   .....
}


  


  In local I have installed ffmpeg in trans.ffmpeg. and its working fine, But how we need to install ffmpeg in heroku .

  


  I have tried by adding heroku buildpacks
heroku buildpacks:add https://github.com/jonathanong/heroku-buildpack-ffmpeg-latest.git but its showing me error. May be some issue with config only.

  


  Heroku error :
2020-09-16T11:23:54.292896+00:00 app[web.1]: 9/16/2020 11:23:54 23 [ERROR] Node Media Trans Server startup failed. ffmpeg:/vendor/ffmpeg cannot be executed.

  


  Guys can you please help me reslove this issue

  


• What type file to pass to FFMPEG::Movie.new(file) in the gem ffmpeg (heroku)

  31 août 2020, par AlbertMunichMar

  I have a Rails app hosted in Heroku. I am using the gem ffmpeg to record screenshots.

  


  I get a video from a React App in my controller :

  


  video = params[:video].tempfile
# #tmp/RackMultipart20200831-4-zgw094.mp4>


  


  I try to pass this object, but does not work :

  


  Errno::ENOENT (No such file or directory - the ffprobe binary could not be found in /app/vendor/bundle/ruby/2.5.0/bin:/app/bin:/app/vendor/bundle/bin:/usr/local/bin:/usr/bin:/bin):


  


  I thought it should worked, since FFMPEG::Movie.new(file) is asking for the path, and I am providing it :

  


  Parameters: {"video"=>#, @original_filename="89.mp4", @content_type="video/mp4", @headers="Content-Disposition: form-data; name=\"video\"; filename=\"89.mp4\"\r\nContent-Type: video/mp4\r\n">}


  


  see : tmp/RackMultipart20200831-4-q2yi74.mp4>. This is the temp path right ?

  


  Maybe it's looking for the file in the wrong path, but how can I specify it ?

  


  I also tried :

  


  File.open(video, 'r') do |file|
  FFMPEG::Movie.new(file.path)
end


  


  But also wrong path. Could someone help me ?

  


  Buildpack is installed in heroku.

  


  I used the CLI installation :

  


  heroku create --buildpack https://github.com/FFmpeg/FFmpeg.git


  


  With following output :

  


  remote: -----> ffmpeg app detected
remote: -----> Install ffmpeg
remote:        DOWNLOAD_URL =  https://johnvansickle.com/ffmpeg/builds/ffmpeg-git-amd64-static.tar.xz
remote:        exporting PATH
remote: -----> Discovering process types
remote:        Procfile declares types -> (none)


  


  It seems to be installed.

  


  But I keep getting this error :
