  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

  • Supporting all media types

    13 avril 2011, par

    Unlike most software and media-sharing platforms, MediaSPIP aims to manage as many different media types as possible. The following are just a few examples from an ever-expanding list of supported formats : images : png, gif, jpg, bmp and more audio : MP3, Ogg, Wav and more video : AVI, MP4, OGV, mpg, mov, wmv and more text, code and other data : OpenOffice, Microsoft Office (Word, PowerPoint, Excel), web (html, CSS), LaTeX, Google Earth and (...)

  • Rails 3 : How can I make Paperclip-FFMPEG work ?

    9 novembre 2011, par remino

    I have Rails 3.0.3 with these gems :

    • delayed_job 2.1.4
    • delayed_paperclip 0.7.1
    • paperclip 2.3.16
    • paperclip-ffmpeg 0.7.0

    (This combination is very specific. Some newer gems will not work with others.)

    Here's my Video model :

    class Video < Upload
    
  has_attached_file :file, :default_style => :view, :processors => [:ffmpeg],
    
    :url => '/system/:class/:attachment/:id/:style/:basename.:extension',
    
    :path => ':rails_root/public/system/:class/:attachment/:id/:style' \
    
      + '/:basename.:extension',
    
    :default_url => '/images/en/processing.png',
    
    :styles => {
    
      :mp4video => { :geometry => '520x390', :format => 'mp4',
    
        :convert_options => { :output => { :vcodec => 'libx264',
    
          :vpre => 'ipod640', :b => '250k', :bt => '50k',
    
          :acodec => 'libfaac', :ab => '56k', :ac => 2 } } },
    
      :oggvideo => { :geometry => '520x390', :format => 'ogg',
    
        :convert_options => { :output => { :vcodec => 'libtheora',
    
          :b => '250k', :bt => '50k', :acodec => 'libvorbis',
    
          :ab => '56k', :ac => 2 } } },
    
      :view => { :geometry => '520x390', :format => 'jpg', :time => 1 },
    
      :preview => { :geometry => '160x120', :format => 'jpg', :time => 1 }
    
    }
    
  validates_attachment_content_type :file, :content_type => VIDEOTYPES,
    
    :if => Proc.new { |upload| upload.file.file? }
    
  process_in_background :file
    
end

    When creating a new Video object with attachment, the original is saved, but no conversion will be done. Even calling Video.last.file.reprocess! won't to a thing except returning true. (Not sure what "true" means in this case as it didn't work.)

    I tried hardcoding the path to ffmpeg in Paperclip::options[:command_path]. I even tried deleting the paperclip-ffmpeg.rb file and replacing it with a blank file. Really thinking I'd get an exception by doing the later, instead, I simply got "true" again.

    It feels like the paperclip-ffmpeg.rb is being loaded, because it is required by config/application.rb, but nothing is called in it when trying to generate a thumbnail or convert a video.

    Can anyone help me with this ? Thanks in advance !

  • FFmpeg HLS streaming - Why the program date time of older segment changing when re-streaming after discontinuity

    9 novembre 2020, par Suriya Krish

    Following is the ffmpeg command to stream the data.

    


    ffmpeg -re -f avfoundation 
-framerate 30 -i 0 
-codec:v h264_videotoolbox -x264-params keyint=120:scenecut=0 
-codec:a copy -f hls 
-hls_list_size 60 
-hls_time 10 
-hls_flags delete_segments 
-hls_flags +append_list 
-hls_flags +discont_start 
-hls_flags +program_date_time 
-strftime 1 
-strftime_mkdir 1 
-hls_segment_filename 
'%Y%m%dT%H%M%S%z.ts' playlist.m3u8


    


    Following is the playlist.m3u8 content which generated for few seconds.

    


    #EXTM3U
#EXT-X-VERSION:3
#EXT-X-TARGETDURATION:10
#EXT-X-MEDIA-SEQUENCE:0
#EXT-X-DISCONTINUITY
#EXT-X-DISCONTINUITY
#EXTINF:10.000000,
#EXT-X-PROGRAM-DATE-TIME:2020-11-09T22:07:53.000+0530
20201109T220753+0530.ts
#EXTINF:10.000000,
#EXT-X-PROGRAM-DATE-TIME:2020-11-09T22:08:03.000+0530
20201109T220803+0530.ts
#EXT-X-ENDLIST


    


    When the re-stream happens(in case of restarting the streaming service), the program date time of older segments(before #EXT-X-DISCONTINUITY) also get changed like below, which is unexpected.

    


    #EXTM3U
#EXT-X-VERSION:3
#EXT-X-TARGETDURATION:10
#EXT-X-MEDIA-SEQUENCE:0
#EXT-X-DISCONTINUITY
#EXT-X-DISCONTINUITY
#EXTINF:10.000000,
#EXT-X-PROGRAM-DATE-TIME:2020-11-09T22:12:50.633+0530
20201109T220753+0530.ts
#EXTINF:10.000000,
#EXT-X-PROGRAM-DATE-TIME:2020-11-09T22:13:00.633+0530
20201109T220803+0530.ts
#EXT-X-DISCONTINUITY
#EXTINF:10.000000,
#EXT-X-PROGRAM-DATE-TIME:2020-11-09T22:13:12.000+0530
20201109T221312+0530.ts
#EXTINF:5.400000,
#EXT-X-PROGRAM-DATE-TIME:2020-11-09T22:13:22.000+0530
20201109T221322+0530.ts
#EXT-X-ENDLIST


    


    Why the program date time of older segment should change ? Should we add any arguments in ffmpeg command to handle this ?
