• ffmpeg overlay fadein/fadeout is not working [duplicate]

  22 avril 2021, par user15602767

  This is my normal overlay filter without any fadein/fadeout

  


  ffmpeg -i .\urban_pop_b4.mp4 -i .\logos\cfe-coffee.png -filter_complex "overlay=700:300:enable=between(t\,3\,6)" output.mp4


  


  When I include the fade-in/fade-out option as in docs I dont get any overlay at all(no error thrown)

  


  ffmpeg -i .\urban_pop_b4.mp4 -i .\logos\cfe-coffee.png -filter_complex "[1:v]fade=t=in:st=5:d=1,fade=t=out:st=10:d=1[over];[0:v][over]overlay=700:300:enable=between(t\,3\,6)" output.mp4

• Unable to convert mov to mp4 using ffmpeg carrierwave in ruby

  9 avril 2021, par LearningROR

  I am unable to convert MOV files to MP4 using carrierwave and FFmpeg.

  


  It does upload mp4 file but does not convert it to mp4 and so on browser only sound gets played not the video.

  


  What I am missing here ? I tried most of the solutions.

  


  Code :

  


  class VideoUploader < CarrierWave::Uploader::Base
  include CarrierWave::MiniMagick
  include CarrierWave::Video
  include CarrierWave::Video::Thumbnailer
  include CarrierWave::FFmpeg
  # Choose what kind of storage to use for this uploader:
  storage :file
  # Override the directory where uploaded files will be stored.
  # This is a sensible default for uploaders that are meant to be mounted:
  def store_dir
    "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
  end
  version :video, :if => :video? do
    process :encode
  end
  version :thumb do
    process thumbnail: [{format: 'jpg', quality: 8, size: 360, logger: Rails.logger, square: false}]
    def full_filename for_file
      jpg_name for_file, version_name
    end
  end
  def encode
    tmp_path = File.join( File.dirname(current_path), "tmpfile.mp4" )
    movie = FFMPEG::Movie.new(current_path)
    movie.transcode(tmp_path, custom: %w(-c:v libx264 -c:a aac -vf format=yuv420p -movflags +faststart)) do |progress|
      puts progress
    end
    File.rename tmp_path, current_path
  end
  protected
  def video?(new_file)
    new_file.content_type.include? 'video'
  end
end

• FFmpeg - Convert video changing resolution and bitrates

  8 avril 2021, par parvares

  I’m trying to convert a video and change these parameters :

  


  resolution : from 1.280x720 to 640x360 pixels

  


  average bitrate : from 1.410 to 300 kb/s

  


  maximum bitrate : from 1.680 to 2500 kb/s

  


  Sampling rate : from 48.0 to 44.1 kHz

  


  Bit rate audio : 128 kb/s

  


  I used this string with ffmpeg vers. 4.3.2-2021-02-20 full build :

  


  ffmpeg -i input.mp4 -c:v -vf scale=640:360 libx264 -b:v 300k -maxrate 2500k -bufsize 2500k -crf 25 -c:a -ar 44100 libfdk_aac -b:a 128k output.mp4


  


  I get the error : “ffmpeg unable to find a suitable output format for scale ‘640:360’ scale 640:360 : invalid argument”. Could you help me please ?
