  • No such file or directory Error with FFMPEG + CarrierWave screenshot method

    10 juillet 2013, par dodgerogers747

    I am using AWS CORS to upload videos to my site, all of which works as planned.

    I have the following model method which runs as an after_create callback (for speed) to take a screenshot from the video file on AWS. I plan to move this out into a delayed job but I don't think this will solve this particular issue. Please advise if mistaken.

    I use FFMPEG to take a screenshot from the AWS self.file location, I then send the file to CarrierWave by saving the file to self.screenshot where it is uploaded to AWS.

    Approx. 50% of the time it errors out with Errno::ENOENT - No such file or directory for the location of the screenshot image.

    How can I rectify my code to remove this error and how come it only occurs around 50% of the time ? If anyone needs more code just shout.

    video.rb

    after_create :take_screenshot
    

    
mount_uploader :screenshot, ImageUploader
    

    
  def take_screenshot
    
    location = "#{Rails.root}/public/uploads/tmp/screenshots/#{unique}_#{File.basename(file)}.jpg"
    
    system `ffmpeg #{log_level} -i #{self.file} -ss 00:00:0#{time_frame} -vframes 1 #{location}`
    
    logger.debug "Trying to take screenshot from #{self.file}"
    
    #pass the actual file to CarrierWave to handle the image upload
    
    self.screenshot = File.open(location)
    
    self.save
    
    logger.debug "Deleting tmp file: #{location}: #{File.delete(location)}" if self.screenshot.present?
    
  end
    

    
def unique
    
    (0..6).map{(65+rand(26)).chr}.join
    
  end
    

    
def log_level
    
    "-loglevel panic"
    
  end
    

    
  def time_frame
