• Android native runtime fails to load symbols even though they are actually found in the loaded .so files

  25 octobre 2017, par Gopinath

  I have compiled ffmpeg v3.4 using NDK v15.2 and I’m creating a wrapper lib called ffmpeg-jni.

  static {
  
      try {
  
          System.loadLibrary("avutil");
  
          System.loadLibrary("avcodec");
  
          System.loadLibrary("avformat");
  
          System.loadLibrary("swscale");
  
          System.loadLibrary("avfilter");
  
          System.loadLibrary("ffmpeg-jni"); // Exception here line#101
  
          loadedLibraries = true;
  
      } catch (Throwable e) {
  
          e.printStackTrace();
  
      }
  
  }

  Below is the exception thrown when loading my wrapper library.

  10-24 11:12:13.819 21499-21499/com.myeglu.android.canary.staging W/System.err: java.lang.UnsatisfiedLinkError: dlopen failed: cannot locate symbol "av_register_all" referenced by "/data/app/com.myeglu.android.canary.staging-2/lib/arm/libffmpeg-jni.so"...

  But, to my surprise, this function is defined in libavformat.so, which loaded successfully ; This is clear from the nm tool outputthat the av_register_all() function is defined (T) in libavformat.so

  Here is a link of all the pre-built libraries that are troubling to make peace at runtime. (There are a few other libraries as well apart from the ffmpeg libs)

  Somebody help me understand what I could be missing in this case. Thanks for your time.

• Load processed video instead of original video - Rails, Dragonfly

  1er février 2016, par Michael B

  In my Rails 4-Project, I am using Dragonfly to upload images and videos.
  For image-processing I use imagemagick, for videoprocessing I use ffmpeg.

  Videos are uploaded and stored in the folder uploads/videos. After processing, they are stored in public/ffmpeg_videos/

  My question is : How can I use the processed-video instead of the uploaded video ?

  e.g. I use this code in the view, to display a video :

  <video src="&lt;%=@video.video.url%>"></video>

  This successfully loads the original video from the upload-path. But what do I have to change, to load the video from the ffmpeg-path ?

  initializers/dragonfly.rb

  require 'dragonfly'
  
  
  
  # Configure
  
  Dragonfly.app(:images).configure do
  
    plugin :imagemagick
  
    protect_from_dos_attacks false
  
    secret 'd045734b043b4383a246c5c8daf2d3e31217dc8b030f21861e4fd16c4b72d382'
  
    url_format '/media/:job/:name'
  
  
  
    datastore :file,
  
              root_path: Rails.root.join('uploads/images/'),
  
              server_root: Rails.root.join('uploads')
  
  end
  
  
  
  Dragonfly.app(:videos).configure do
  
    secret 'd045734b043b4383a246c5c8daf2d3e31217dc8b030f21861e4fd16c4b72d382'
  
    url_format "/video/:job/:name"
  
  
  
    datastore :file,
  
              root_path: Rails.root.join('uploads/videos/'),
  
              server_root: Rails.root.join('uploads')
  
  end
  
  
  
  # Logger
  
  Dragonfly.logger = Rails.logger
  
  
  
  # Mount as middleware
  
  Rails.application.middleware.use Dragonfly::Middleware, :images
  
  Rails.application.middleware.use Dragonfly::Middleware, :videos
  
  
  
  # Add model functionality
  
  if defined?(ActiveRecord::Base)
  
    ActiveRecord::Base.extend Dragonfly::Model
  
    ActiveRecord::Base.extend Dragonfly::Model::Validations
  
  end
