• convert mp3 to wav using xuggle getting exception

  24 juin 2013, par Felix

  I am trying to convert mp3 to wav and the code is here :

  String mp3 = "F:\\work\\pic2talk38512.mp3";
  
  String wav = "F:\\work\\pic2talk38512.wav";
  
  TranscodeAudioAndVideo.transcodeTest(mp3, wav);
  
  
  
  public static void transcode(String sourceUrl, String destinationUrl) {
  
      IMediaReader reader = ToolFactory.makeReader(sourceUrl);
  
      reader.addListener(ToolFactory.makeWriter(destinationUrl, reader));
  
  
  
      while (reader.readPacket() == null)
  
              do {
  
              } while (false);
  
  }

  I got this exception :

  I know that xuggle can figure out the conversion by the extension.But why this time is failed ?

  thanks

  edit :

  previously I can convert mp3 which params(MPEG 22.1KHZ 32kbps) to wav, but If I use the mp3(MPEG 44.1KHZ 62kbps) I got this exception ?

  How this happened ?

• How do I get videos to upload using ruby on rails carrierwave-video ?

  9 juillet 2016, par Eric

  Updated as of July 9, 2016

  I tried to follow the instructions on the github website for the video uploader process using carrierwave-video gem but get an error that says the file or directory mmpeg -i doesn’t exist.

  The upload path for images functions correctly, just not the video one.

  I have added all of the following code necessary to help solve the error and minified as much as i possibly could.

  Video uploader code using carrierwave

  class VideoUploader < CarrierWave::Uploader::Base

    include CarrierWave::Video
  
    storage :file
  
  
  
    version :mp4 do
  
      process :encode_video => [:mp4, resolution: "100x100"]
  
    end
  
  
  
    def store_dir
  
      "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
  
    end
  
  end

  Here is the movie controller code that handles uploading of videos

  class MoviesController < ApplicationController
  
     include MoviesHelper
  
  
  
     def index
  
        mode "index"
  
     end
  
  
  
     def show
  
        mode "show"
  
     end
  
  
  
     def new
  
        mode "new"
  
     end
  
  
  
     def edit
  
        mode "edit"
  
     end
  
  
  
     def create
  
        mode "create"
  
     end
  
  
  
     def update
  
        mode "update"
  
     end
  
  
  
     def destroy
  
        mode "destroy"
  
     end
  
  
  
     def review
  
        mode "review"
  
     end
  
  
  
     def approve
  
        mode "approve"
  
     end
  
  
  
     def deny
  
        mode "deny"
  
     end
  
  end

  Here is the model data for the movie that goes with it

  class Movie < ActiveRecord::Base
  
    attr_accessible :created_on, :description, :maintenance, :reviewed, :subplaylist_id, :title, :user_id, :video, :remote_video_url
  
    belongs_to :user
  
    belongs_to :subplaylist
  
    mount_uploader :video, VideoUploader
  
  end

  Here is where the movie is supposed to be displayed but it is not working

  <% provide(:title, "Movie: Where movies are made!") %>
  
  <% provide(:keywords, "movies, video") %>
  
  <% provide(:description, "This is the place where users showcase their wonderful video talent.") %>
  
  <p>&lt;%= notice %></p>
  
  <h1 class="pageheader">&lt;%= @movie.title %></h1>
  
  <br />
  
  <p class="pagetext">&lt;%= video_tag(@movie.video_url.to_s, controls: true, class: "imagebox") %></p>
  
  <p class="pagetext">&lt;%= @movie.description %></p>
  
  <p class="pagetext">Created on: &lt;%= @movie.created_on.strftime("%B-%d-%Y") %></p>
  
  <p class="pagetext">Owner: &lt;%= getType(@movie.user) %>&lt;%= link_to @movie.user.vname, user_path(@movie.user) %></p>
  
  <br />
  
  <p class="pagetext">&lt;%= link_to 'Back', mainplaylist_subplaylist_path(@subplaylist.mainplaylist, @movie.subplaylist) %></p>

  Here is where the movie new action is

  <% provide(:title, "Movie: Create new movies here!") %>
  
  <% provide(:description, "New movies are uploaded only to the site when the movie gets approved.") %>
  
  <h1 class="pagetextheader">New movie</h1>
  
  &lt;%= render 'form' %>
  
  <p class="pagetext">&lt;%= link_to 'Back', mainplaylist_subplaylist_path(@subplaylist.mainplaylist, @subplaylist) %></p>

  Here is where the movies forum parameters are

  <%= form_for([@subplaylist, @movie], :html=>{:multipart => true}) do |f| %>
  
    <% if @movie.errors.any? %>
  
      <div>
  
        <h2>&lt;%= pluralize(@movie.errors.count, "error") %> prohibited this movie from being saved:</h2>
  
  
  
        <ul>
  
        &lt;% @movie.errors.full_messages.each do |msg| %>
  
          <li>&lt;%= msg %></li>
  
        &lt;% end %>
  
        </ul>
  
      </div>
  
    &lt;% end %>
  
    <br />
  
    <div class="pagetext">
  
      &lt;%= f.label :title %><br />
  
      &lt;%= f.text_field :title %>
  
    </div>
  
    <div class="pagetext">
  
      &lt;%= f.file_field :video %>
  
    </div>
  
    <div class="pagetext">
  
      &lt;%= f.label :remote_video_url, "or video URL" %><br />
  
      &lt;%= f.text_field :remote_video_url %>
  
    </div>
  
    <div class="pagetext">
  
      &lt;%= f.label :description %><br />
  
      &lt;%= f.text_area :description %>
  
    </div>
  
    <div class="pagetext">
  
      &lt;%= f.submit %>
  
    </div>
  
    <br />
  
  &lt;% end %>

  Error message

• 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)

  

  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
