  • Carrierwave watermark a movie

    15 mai 2016, par Felix

    I’m uploading a movie with carrierwave to amazon S3. While uploading I want to watermark the movie.

    How can I do this ? How can I use stermio-ffmpeg while uploading ?

    I’m using a Rails application.

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

    16 juin 2016, par Felix

    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
