  • Paperclip Upload Video Without Styles

    16 mars 2017, par Moamen Naanou

    Background :

    In my app, there is a model has image attachment using paperclip gem, now as per new requirements, I have to let the same attachment accept MP4 video files as well and the only validation I have to implement is about file size.

    Product Model (with image attachment only) :

    class Product < ActiveRecord::Base
    
  has_attached_file :file,
    
                    :styles => { medium: '300x300>', thumb: '100x100>' },
    
                    :processors => [:thumbnail],
    
                    :url => '/assets/:id/:style/:hash.:extension',
    
                    :hash_digest=>'SHA1',
    
                    :use_timestamp => false
    

    

    
  validates_attachment_content_type :file, :content_type => /\A(image)\/.*\Z/
    
  validates_attachment_size :file, :less_than => 5.megabytes
    
end

    So after reading many related questions, to accept a video file as well, I’ve used gem paperclip-av-transcoder and installed ffmpeg (Mac) using :

    brew install ffmpeg --with-fdk-aac --with-ffplay --with-freetype --with-frei0r --with-libas

    Then finally I’ve revised my model to be :

    class Product < ActiveRecord::Base
    
  has_attached_file :file,
    
                    :styles => lambda {|file| if file.instance.is_image?
    
                                                { medium: '300x300>', thumb: '100x100>' }
    
                                              elsif file.instance.is_video?
    
                                                {:thumb => { :geometry => "100x100#", :format => 'jpg', :time => 10}}
    
                                              end },
    
                    :processors => lambda {|file| if file.is_image?
    
                                                    [:thumbnail]
    
                                                  elsif file.is_video?
    
                                                    [:transcoder]
    
                                                  end},
    
                    :url => '/assets/:id/:style/:hash.:extension',
    
                    :hash_digest=>'SHA1',
    
                    :use_timestamp => false
    

    

    
  validates_attachment_content_type :file, :content_type => /\A(image|video)\/.*\Z/
    
  validates_attachment_size :file, :less_than => 5.megabytes
    

    
  def is_video?
    
    file_content_type =~ %r(video)
    
  end
    

    
  def is_image?
    
    file_content_type =~ %r(image)
    
  end
    
end

    Now the file field accepts both videos & images but the video shouldn’t be compressed, because if it is compressed, I will get IO Error [Closed Stream]

    Question :

    I’m expecting compressed MP4 file to be received from Mobile client(through REST API) and I don’t want to generate any thumb image or any other style or do any processing on this video and without installing any processor (ffmpeg in my case) and if I did so currently, I’m getting the following error because ImageMagic doesn’t work with video files :

    Paperclip::Errors::NotIdentifiedByImageMagickError

    Any ideas ?

  • ffmpeg unable to find encoder 'libvorbis'

    31 mars 2020, par scientiffic

    I'm unable to transcode a video file to webm because my machine isn't able to find libvorbis. When I run the following command :

    



    ffmpeg -y -i /public/uploads/tmp/1382112521-11953-7661/webm_Untitled.mov -vcodec libvpx -acodec libvorbis -s 640x360  -b 1500k -ab 160000 -f webm -g 30 -aspect 1.7777777777777777 /public/uploads/tmp/1382112521-11953-7661/tmpfile.webm


    



    I get the error

    



    Unknown encoder 'libvorbis'


    



    I already have libvorbis installed on my machine, though (When I try "brew install libvorbis, it tells me : Warning : libvorbis-1.3.3 already installed).

    



    How can I solve this problem ?
