  • Ajouter notes et légendes aux images

    7 février 2011, par

    Pour pouvoir ajouter notes et légendes aux images, la première étape est d’installer le plugin "Légendes".
    Une fois le plugin activé, vous pouvez le configurer dans l’espace de configuration afin de modifier les droits de création / modification et de suppression des notes. Par défaut seuls les administrateurs du site peuvent ajouter des notes aux images.

  • Video Processing via Bluetooth

    16 juillet 2012, par kerim yucel

    The application I am currently developing processes each frames using a native code and it should record the video as well. I tried SDK for this purpose but certain restrictions didn't allow me to do so, so I switched to NDK for a video recording code piece.

    Apparently, my algorithm seriously uses CPU, upto %70 percent in the worst case. Before I actually start working on a video recorder, I wanted to try the following approach.

    I will process the preview frames using an android phone and send it to another phone (which uses same application and same model) for recording. My questions are :

    1.Should I try WiFi instead of Bluetooth ? I am developing the application for API 8 so I don't have WiFi-Direct, therefore I should do some socket programming, which would possibly complicate things a bit for me since Bluetooth can easily be set up using SDK.

    2- Will I be available to record the frames as a video at the receiving end ? I will receive each frame with certain metadata embedded to it and should record them using the other phone. I doubt I will be able to do it using SDK, so NDK along with ffmpeg seems to be the best choice ? Any suggestions related to this question will be more than welcome.

    3-Here comes the best part. I am recording the video with the lowest resolution that,after compressed, takes no more than 14mb space for a 10 minute long video. I have to reach the raw frames to send it to other end, encode and compress it. Any ideas related to possible flooding of Bluetooth/Wi-Fi because of big-sized raw frames ?

    Any other approaches and answers will be much appreciated. Thanks.

  • Video error while processing

    19 décembre 2012, par joelmaranhao

    Trying out paperclip-ffmpeg gem with Rails 3.1

    In my model

    class Video < ActiveRecord::Base
     belongs_to :creative_service

     has_attached_file :asset, :styles => {
       :medium => { :geometry => "640x480", :format => 'flv' },
       :thumb => { :geometry => "100x100#", :format => 'jpg', :time => 10 }
     }, :processors => [:ffmpeg]
    end

    The error message when uploading a MPG file :

    Video error while processing video for MOV0652220121219-19138-1ybt1gp: Command 'ffmpeg -i :source -y -s 640x480 :dest' returned 1. Expected 0

    I am a total newbie with video processing. Any hint is welcome.

  • converting a UYVY FFmpeg

    19 février 2013, par Engine

    I want to read and show a video using opencv. I've recorded with Direct-show, the Video has UYVY (4:2:2) codec, since opencv can't read that format, I want to convert the codec to an RGB color model, I readed about ffmpeg and I want to know if it's possible to get this done with it ? if not if you a suggestion I'll be thankful.
