• ffmpeg video merging issues for videos recorded from andriod mobile phone

  14 avril 2021, par Nishit Modi

  Following is the command I'm using :

  


  sudo ffmpeg -i video1.mp4 -i video2.mp4 -filter_complex "[1]tpad=start_mode=clone:start_duration=15[tr];[0][tr]xstack=inputs=2:layout=0_0|w0_0[v];[1:a]adelay=15s:all=true[a1];[0:a][a1]amix=inputs=2[a]" -map "[v]" -map "[a]" output.mp4


  


  It took a couple of hours to merge the videos. Original videos are 6 MBs in size. Merged video is approx 2 GB in size.

  


  It is working fine with videos recorded from the iphone.

  


  Update :
The issue is regarding different fps in different videos. If two videos are of different fps, then it is taking too long and eventually break.

  


  Full log :

  


  ffmpeg -i video1.mp4 -i video2.mp4 -filter_complex "[1]tpad=start_mode=clone:start_duration=15[tr];[0][tr]xstack=inputs=2:layout=0_0|w0_0[v];[1:a]adelay=15s:all=true[a1];[0:a][a1]amix=inputs=2[a]" -map "[v]" -map "[a]" output_ia_2.mp4

• 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

  Already tried out ffmpeg overlay image with fade in and fade out

  


• 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
