  • Calculate VMAF for HEVC or H264 with ffmpeg

    3 juin 2020, par ringola27

    I am able to calculate VMAF for the videos encoded with VP9 but not for the videos encoded with HEVC and H264.

    



    I am getting the output :

    



    VMAF score: nan

    



    For the Command Line : 
ffmpeg -i netflix200kHEVC.mp4 -i netflixboxing.y4m -lavfi "libvmaf=model_path=/usr/local/share/model/vmaf_v0.6.1.pkl" -f null -

    



    Do you know this kind of problem ? How can I solve it ?

    



        ffmpeg -i netflix200kHEVC.mp4 -i netflixboxing.y4m -lavfi "libvmaf=model_path=/usr/local/share/model/vmaf_v0.6.1.pkl" -f null -

  • Paperclip with heroku and paperclip, migration fails

    2 décembre 2013, par jdartland

    I have a created ruby on rails application and I'm using paperclip to handle my file uploads.
    Paperclip works just fine on my local machine. But my video upload stops working when I deploy to Heroku. Does anyone know whats going wrong. I also get an error when I try to upload a video which says that the video filename does not exist. The photo upload works but not the Video, I'm using paperclip iwth nested attributes and ffmpeg.

    Upload Error log :

  • Raising and Rescuing Custom Exception

    24 décembre 2013, par cmw

    I'm using Rails 3 with Carrierwave and FFMPEG to handle video uploads and encoding.

    In my uploader, I'm using FFMPEG to grab the duration of the video from cache before storing it.

    I'd like to raise a custom exception if the video's duration exceeds a specific length and then route the user accordingly. I've spent quite a bit of time trying to figure out how to create, raise and rescue my own custom exceptions in Rails – but, I've had no luck.

    Some posts I've used to try to piece this together include this stack overflow post and this article on customized exception handling in Rails 3. I've had no luck yet.

    I'm hoping someone can offer guidance on the proper approach to this. My mind is blown.

    Below is what my uploader looks like :

    class VideoUploader &lt; CarrierWave::Uploader::Base
    

    
  before :store, :ffmpeg
    

    
  # Set storage type
    
  storage :fog
    

    
  # Override the directory where uploaded files will be stored.
    
  def store_dir
    
    "#{model.class.to_s.underscore}/videos/#{model.id}"
    
  end
    

    
  # Add a white list of extensions which are allowed to be uploaded.
    
  def extension_white_list
    
    %w(mov avi mp4 mkv wmv mpg)
    
  end
    

    
  def full_cache_path
    
    "#{::Rails.root}/public/#{cache_dir}/#{cache_name}"
    
  end
    

    
  private 
    

    
  def ffmpeg(*args)
    
    @model.video.cache_stored_file!
    
    movie = FFMPEG::Movie.new("#{model.video.full_cache_path}")
    
    if movie.duration > 600
    
      raise "my custom exception will go here one day"
    
    end
    
  end
    

    
end
