Rails using stremio-ffmpeg gem to watermark a movie while uploading

I am using carrierwave to upload a movie to amazon s3 that works perfect.

Now I want to add a watermark to the movie while uploading or after uploading, I don't know, what's the best way?

I tried this:

movie_controller.rb
action uploadVideo

movie = FFMPEG::Movie.new(@vid.video.url)

puts "........................................"
puts movie.inspect

if @vid.save


Just to find out if the video is catched from stremio.

But then I got the error that the movie is not found, the problem is that it doesn't look in the amazon s3 bucket, it looks on my local server

No such file or directory - the file '/uploads/tmp/1462954331-3471-8766/VID-20160424-WA0013.mp4' does not exist


What could be the solution? or should I do this in carrierwave uploader?

UPDATE:

When I do this after the .save action it looks at amazon s3 bucket .. but also says that the movie isn't there. But if I call it directly in browser it's displayed.

UPDATE Code:

#Laedt ein Video hoch
def uploadMovie
@user = User.find_by_id session[:user_id]
#Holt alle Channels für die er eine Berechtigung hat (Eingeloggter user)
@user = User.find_by_id session[:user_id]
@knowledgeproviderList = @user.knowledgeprovider
@channels = Channel.where(knowledgeprovider_id: @knowledgeproviderList.pluck(:id))
@vid = Movie.new(movies_params)
@channel = Channel.find(params[:vid][:channel_id])
@vid.channel = @channel

#Fügt dem Movie einen Tag hinzu
createTag params
createCategory params



if @vid.save
flash[:notice] = t("flash.saved")

#movie = FFMPEG::Movie.new(@vid.video.url)

#puts "........................................"
#puts movie.inspect

redirect_to :action => :add
else
redirect_to :action => :add
end
end


Update error:

movie = FFMPEG::Movie.new(@vid.video.current_path)

options = {watermark: "mages/header.png", resolution: "640x360", watermark_filter: { position: "RT", padding_x: 10, padding_y: 10 } }
movie.transcode("movie.flv", options)


enter image description here

Update:
Added the code in the uploader:

process :watermark_movie

def watermark_movie
if self.file.path
options = {watermark: "images/header.png", resolution: "640x360", watermark_filter: { position: "RT", padding_x: 10, padding_y: 10 } }
self.model.file = FFMPEG::Movie.new(self.file.path).transcode("#{root}/#{cache_dir}/#{self.cache_id}/file.mp4", options)
end
end

# Choose what kind of storage to use for this uploader:

Answer

With Kyle together we figured out that the following is required

only version 1.0.0 works fine

gem 'streamio-ffmpeg', '1.0.0'

The function is now in the carrierwave uploader and looks like this:

  process :watermark_movie

  def watermark_movie
      options = {watermark: "#{Rails.root}/public/images/logo_klein.png", resolution: "640x360", watermark_filter: {position: "RT", padding_x: 10, padding_y: 10},custom: '-strict experimental'}
      #debugger
      tmp_path = File.join File.dirname(current_path), "tmp_file.mp4"
      file = FFMPEG::Movie.new(self.file.path)
      file.transcode tmp_path, options
      File.rename tmp_path, current_path
  end

At the Moment there are no more errors, problem is still that the watermark is not working.

Update:

A working solution is:

system "ffmpeg -i #{self.file.path} -vf 'movie=#{watermarkimage} [watermark]; [in][watermark] overlay=main_w-overlay_w-10:10 [out]' -strict experimental #{tmp_path}"
