    10 avril 2011

    Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

  • How can I mux (or encapsulate) H.264 RTP output into a container using FFMPEG ?

    7 octobre 2013, par Grad

    I am working on the effects of network losses in video transmission. In order to simulate the network losses I use a simple program which drops random RTP packets from the output of H.264 RTP encoding.

    I use Joint Model (JM) 14.2 in order to encode the video. However, I don't use AnnexB format as my output, instead I choose the output as RTP packets. The JM output is generated as RTP packets with RTP headers and payload as a sequence. After that, some of RTP packets are dropped by using a simple program. Then, I can decode the output bitstream by using also JM and it's error concealment methods.

    The main purpose of this process is to evaluate the differences created by network losses on the human video quality perception. In order to measure the perceived quality, the shown video must be in its decoded form (i.e. full resolution) or it can be decodable at the receiver side. The RTP packets created by the JM Encoder cannot be decoded without the JM software installed. However, with the proper header (or container) most video players are able to decode the bitstream. So, the my goal in this question is to encapsulate my encoded RTP packet bitstream in a common container such as AVI or MP4 to have my content decodable at the receiver computer.

    The format of the encoded bitstream in RTP packetized form is as follows :

        ----------------------------------------------------------------------
        | RTP Header #1 | RTP Payload #1 | RTP Header #2 | RTP Payload #2 |...
        ----------------------------------------------------------------------

    In order to find the video quality, I want to make a subjective test with these bitstreams. I can make these test by using the full resolution data decoded by myself whereas it's very inconvenient to crowdsource this subjective test with GBs of video data on the Internet. So, I want to mux these bitstreams into a container (i.e. AVI) by using FFMPEG. I have tried to decode these bitstreams with FFMPEG and FFPLAY ; however, both of them didn't work. I also tried the following command and it didn't work, either.

       ffmpeg - f h264 -i  -vcodec copy -r 25 out.avi

    Which format or muxer should I use ? Do I need to convert these files to any other format ?

  • 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

  • ffmpeg error when using non root user

    29 août 2014, par mkern

    I have installed ffmpeg and it works perfect if you are root or using sudo but it errors out when trying to use it as a non-root user. I have performed the same install on a test VPS and it installs without issue so it appears to be isolated to this cPanel server. I haven’t been able to identify why.
