• No such file or directory - the ffprobe binary could not be found error

  22 juin 2016, par rahul

  I am using carrierwave-video gem uploading videos through carrierwave and it’s not working.

  video_uploader.rb

  class VideoUploader < CarrierWave::Uploader::Base
  
    include CarrierWave::Video
  
    storage :file
  
    def store_dir
  
      "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
  
    end
  
  end

  video.rb

  class Video < ActiveRecord::Base
  
    mount_uploader :file, VideoUploader
  
  
  
    def set_success(format, opts)
  
      self.success = true
  
    end
  
  end

  The error I am getting is :

  No such file or directory - the ffprobe binary could not be found in /home/administrator/.rvm/gems/ruby-2.3.0/bin:/home/administrator/.rvm/gems/ruby-2.3.0@global/bin:/usr/share/rvm/rubies/ruby-2.3.0/bin:/usr/share/rvm/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games

• Getting error on video with Ruby on Rails 4 App

  30 avril 2016, par D.Graves

  So this is the error I get right after I try and upload my video

  

  This is my post show

  <%= video_tag @post.video.url(:medium), controls: true, style: "max-width: 100%;" %>
  
  
  
  <p>
  
    <strong>Description:</strong>
  
  &lt;%= @post.description %>
  
  </p>
  
    &lt;% if @post.user == current_user %>
  
    &lt;%= link_to 'Edit', edit_post_path(@post) %> 
  
  &lt;% end %>|
  
  &lt;%= link_to 'Back', posts_path %>

  This is my post model

  class Post < ActiveRecord::Base
  
   belongs_to :user
  
  
  
   has_attached_file :video, styles: {
  
      :medium => {
  
        :geometry => "640x480",
  
        :format => 'mp4'
  
      },
  
      :thumb => { :geometry => "160x120", :format => 'jpeg', :time => 10}
  
  }, :processors => [:transcoder]
  
  validates_attachment_content_type :video, content_type: /\Avideo\/.*\Z/
  
  end

  I am curious if anyone has run into this before and I am wondering if I can get any help on how to fix this. I am using paperclip av-transcoder gem, ffmpeg and paperclip gem. I can add any more information if needed

  Here is my post controller if this helps

  def index
  
  @posts = Post.all
  
  end
  
  
  
  def show
  
  end
  
  
  
  def new
  
  @post = current_user.posts.build
  
  end
  
  
  
  def edit
  
  end
  
  
  
  def create
  
  @post = current_user.posts.build(post_params)
  
  if @post.save
  
    redirect_to @post, notice: 'Post was successfully created.'
  
  else
  
    render :new
  
  end
  
  end
  
  
  
  def update
  
  if @post.update(post_params)
  
    redirect_to @post, notice: 'Post was successfully updated.'
  
  else
  
    render :edit
  
  end
  
  end
  
  
  
  def destroy
  
  @post.destroy
  
  redirect_to posts_url
  
  end
  
  
  
  private
  
  def set_post
  
    @post = Post.find_by(id: params[:id])
  
  end
  
  
  
  def correct_user
  
    @post = current_user.posts.find_by(id: params[:id])
  
    redirect_to posts_path, notice: "Not authorized to edit this post" if @post.nil?
  
  end
  
  
  
  def post_params
  
    params.require(:post).permit(:description, :video)
  
  end
  
  
  
  
  
   end

  I want to cross compile ffmpeg 2.8.x on Mac OS X 10.10, but I got the following error.

  Before I upgrade Xcode to 7.2, it worked fine.

  For ffmpeg 3.x, there is no such problem. But the ffmpeg version I need is 2.8.x. How can I fix without downgrade Xcode to previous version ?
