  • ffmpeg watermark has no affect on video

    4 juin 2016, par Felix

    I’m using carrierwave to upload movies, and I want to use stremio-ffmpeg to wartermark the uploading video.

    for this I have the following function in the uploader

    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 that the watermark is not working.

    What is my failure in this ?

  • FFMPEG HLS Livestream For High Frame Rates/Action Scenes

    7 novembre 2020, par Devin Dixon

    Obsversation with my current ffmpeg hls livestream implementation. I am getting an HLS from a stream and is transcoding it for another stream as such :

    


    /usr/bin/ffmpeg -y -i rtmp://127.0.0.1:1935/live/3fafa93b-d957-4360-9f9c-3ded474d57f9 -c:v copy -c:a copy -f tee -map 0:a? -map 0:v? [hls_time=1:hls_list_size=8:hls_flags=delete_segments]./media/live/3fafa93b-d957-4360-9f9c-3ded474d57f9/index.m3u8


    


    It works great ! Accept with movie scenes with fast frame rates, namely action movies. How can I tweak my HLS livestream to better deal with scene that have high frame rates ?

    


  • Decrypt or decode ultraviolet videos

    29 mai 2017, par argetlam5

    I was on Vudu because I have some Ultraviolet movies in my collection and I saw you could download them from their site for offline usage.

    The files on the computer from that download are an h264-2000.mp4 file and aac-256.mp4 file (along with a json subtitle file and some other meta data stuff). When I try to run them individually however nothing happens and when I try to convert to m4v with ffmpeg it fails.

    • Are these files encrypted so that only their video player can play it ?
    • Is there a way to combine all of these files that I’m just not aware of ?

    Vudu uses Adobe Air if that gives you any more information.

    Also, if it is encrypted, does that mean it’s illegal for me to try to be messing with these ? I thought since I bought the movie it would be fine to try. I know I could rip the movie with something like handbrake but the quality from Vudu & other Ultraviolet sites is really nice and my computer doesn’t have a bluray reader to try and rip from a bluray.
