• 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 :

    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",
