  • Creating farms of unique websites

    13 avril 2011, par

  • Rails 6 ActiveStorage re-encode videos

    14 novembre 2019, par gorgon

    Tried to use ActiveStorage::Previewer:VideoPreviewer to reencode original videos into smaller resolution and length, but it seems that it can only produce/extract image from video.

    Also tried to create a custom VideoPreviewer by using ffmpeg command to reencode videos, and rails seems to always favor the default ActiveStorage::Previewer::VideoPreviewer. Even if i kick out default video preview from rails previewer and put the custom one, rails still tried to use imagemagick and generates images

    class VideoPreviewer < ActiveStorage::Previewer
    
  ARGS = %w"ffmpeg args..."
    

    
  def self.accept?(blob)
    
    blob.content_type == 'video/mp4'
    
  end
    

    
  def preview
    
    download_blob_to_tempfile do |input|
    
      draw "ffmpeg", "-y", "-i", input.path, *ARGS do |output|
    
        yield io: output, filename: "#{blob.filename.base}.mp4", content_type: "video/mp4"
    
      end
    
    end
    
  end
    

    
  private
    

    
  def capture(*argv, to:)
    
    argv << to.path
    
    to.binmode
    
    IO.popen(argv) { |out| puts out.read }
    
    to.rewind
    
  end
    
end

    Is there a way to achieve this with ActiveStorage or i need to go back using paperclip or some other gem ?

  • map DVB subtitle Stream is not showing as default language

    13 janvier 2021, par Psyco23

    I have a problem showing the subtitles on stream directly.

    


    I did this via map

    


    -map 0:0 -map 0:1 -map 0:3

    


    And it works so well that I have chosen the English audio, the video, and the Spanish subtitles

    


    The problem is when you open the stream

    


    Subtitles are not shown directly. I have to TURN on in VLC

    


    Is there a way, via ffmpeg or map, for my subtitles to appear directly without activating it ?

    


  • Using WebHDFS to play video over HTTP

    3 février 2015, par Qin.Yang

    I used ffmpeg + libx264 to convert file format as H264, then uploaded the file to Hadoop. I used WebHDFS to access the file by HTTP, but can not online play. If I download this file over HTTP, it can play by HTML5 video. My English is poor, hope you know what I mean.
