• Adding video with paperclip av-transcoder

  16 avril 2016, par D.Graves

  Okay so I tried this awhile back and I couldn’t get it to work. So I started new and still struggling with this. I am able to upload images no problem. But for some reason I am getting errors when I try to upload videos. I have ffmpeg installed and the latest paperclip av-transcoder installed as well.

  This is the error that I’m getting
  

  This is my post model

  class Post < ActiveRecord::Base
  
   belongs_to :user
  
   has_attached_file :video, styles: {
  
      :medium => {
  
        :geometry => "640x480",
  
        :format => 'mp4'
  
      },
  
      :thumb => { :geometry => "160x120", :format => 'jpeg', :time => 10}
  
  }, :processors => [:transcoder]
  
   validates_attachment_content_type :video, content_type: /\Avideo\/.*\Z/
  
  end

  This is my post controller

  def index
  
  @posts = Post.all.order("created_at DESC")
  
  end
  
  
  
  def show
  
  end
  
  
  
  def new
  
  @post = current_user.posts.build
  
  end
  
  
  
  def edit
  
  end
  
  
  
  def create
  
  @post = current_user.posts.build(post_params)
  
  if @post.save
  
    redirect_to @post, notice: 'Post was successfully created.'
  
  else
  
    render :new
  
  end
  
  end
  
  
  
  def update
  
  if @post.update(post_params)
  
    redirect_to @post, notice: 'Post was successfully updated.'
  
  else
  
    render :edit
  
  end
  
  end
  
  
  
  def destroy
  
  @post.destroy
  
  redirect_to posts_url
  
  end
  
  
  
  private
  
  # Use callbacks to share common setup or constraints between actions.
  
  def set_post
  
    @post = Post.find_by(id: params[:id])
  
  end
  
  
  
  def correct_user
  
    @post = current_user.posts.find_by(id: params[:id])
  
    redirect_to posts_path, notice: "Not authorized to edit this post" if     @post.nil?
  
  end
  
  
  
  # Never trust parameters from the scary internet, only allow the white list through.
  
  def post_params
  
    params.require(:post).permit(:description, :image, :video)
  
  end
  
  
  
  def bscenes_params
  
      params.require(:post).permit(:video)
  
  end
  
  end

  This is the tag I am using on my show page

  <%= video_tag bscene.video.url(:medium), controls: true, style: "max-width: 100%;" %>

  I followed step by step the steps on this site
  http://alloffices.io/posts/heroku-s3-paperclip-av-transcoder-for-video-uploads

  Don’t know why Im getting the NamError. Any help at all would be a ton of help

  When I take away the "bscene" from the tag and controller I then get this when I upload.

  

• FFMPEG with Gradle Experimental Android plugin

  12 avril 2016, par Spartan

  I extracted ffmpeg in ndk’s source folder then compiled it there only for that I followed this :http://www.roman10.net/2013/08/18/how-to-build-ffmpeg-with-ndk-r9/

  So I successfully(generated android folder with arm/lib and arm/include files).

  After that I created one Android.mk file in $NDK/sources/ffmpeg/android/arm and one Android.mk in my android project(src/main/jni folder).

  My src/main/jni/Android.mk is like this :

  LOCAL_PATH := $(call my-dir)
  
  
  
  include $(CLEAR_VARS)
  
  
  
  LOCAL_MODULE    := tutorial01
  
  LOCAL_SRC_FILES := tutorial01.c
  
  LOCAL_LDLIBS := -llog -ljnigraphics -lz
  
  LOCAL_SHARED_LIBRARIES := libavformat libavcodec libswscale libavutil
  
  
  
  include $(BUILD_SHARED_LIBRARY)
  
  $(call import-module,ffmpeg-3.0.1/android/arm)

  Now I stuck here and trying to put these details in build.gradle files like showing in this documentation :
  http://tools.android.com/tech-docs/new-build-system/gradle-experimental

  for example :

  model {
  
  
  
      repositories {
  
  
  
          libs(PrebuiltLibraries) {
  
  
  
              prebuilt {
  
  
  
                  headers.srcDir "path/to/headers"
  
  
  
                  binaries.withType(SharedLibraryBinary) {
  
  
  
                      sharedLibraryFile = file("lib/${targetPlatform.getName()}/prebuilt.so")
  
  
  
                  }
  
  
  
              }
  
  
  
          }
  
  
  
      }
  
  
  
      android.sources {
  
          main {
  
              jniLibs {
  
                  dependencies {
  
                      library "prebuilt"
  
                  }
  
              }
  
          }
  
      }
  
  }

  But not able transform exact Android.mk(src/main/jni) to this and apart from it I have one more Android.mk in my android/arm folder so how I can call this makefile or should I put that details also in my build.gradle like above.

  I tried like this and using ndk-build command successfully generated jniLibs with .so files but I am getting libavcodec/avcodec.h : No such file or directory while building project.

  android.sources {
  
      main {
  
          jni {
  
              source {
  
                  srcDirs = ['src/main/myJni']
  
              }
  
  
  
          }
  
  
  
      }
  
  
  
      main {
  
          jniLibs {
  
              source {
  
                  srcDirs = ['src/main/libs']
  
              }
  
          }
  
      }
  
  
  
  }
