• Increase the sound of the first input in certain moments

  22 mars 2023, par Ali Azmoodeh

  I have a code that has two inputs. The first entry is played with a 2 second delay. The second entry is played with a 1 second delay. These entries are repeated as the video progresses. The volume of the two inputs sometimes overlaps

  


  when this happens I want the volume of the first input to be 1 and the volume of the input The latter should be set to 0.3

  


• 【carrierwave+ffmpeg】can't upload the video with sound

  10 avril 2020, par ken akita

  I want to make "Fake Instagram" Rails application.
then I made the uploader and I can upload the video(mp4), but no sound.
I can listen to the sound on my desktop but can't on my application, like this image, speakers not working.
enter image description here

  



  Code is here. I guess something wrong with image_uploader.rb or show.html.erb.
Note that first I made the ImageUploader to upload image, then I want to add video posting system to upload video. Both uploading done, but video without sound.
Really thank you for your advise !

  



  *image_uploader.rb
require 'streamio-ffmpeg'

class ImageUploader < CarrierWave::Uploader::Base
  include CarrierWave::MiniMagick
  process resize_to_fit: [230, 183]

  storage :file

  def store_dir
    "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
  end

  version :thumb do
    process resize_to_fit: [230, 183]
  end
  version :screenshot do
    process :screenshot
    def full_filename (for_file = model.logo.file)
      "screenshot.jpg"
    end
  end

  def screenshot
    tmpfile = File.join(File.dirname(current_path), "tmpfile")

    File.rename(current_path, tmpfile)

    movie = FFMPEG::Movie.new(tmpfile)
    movie.screenshot(current_path + ".jpg", {resolution: '230x183' }, preserve_aspect_ratio: :width)
    File.rename(current_path + ".jpg", current_path)

    File.delete(tmpfile)
  end

  def extension_whitelist
    %w(jpg jpeg gif png mp4)
  end
end
