• Progress with rtc.io

  12 août 2014, par silvia

  At the end of July, I gave a presentation about WebRTC and rtc.io at the WDCNZ Web Dev Conference in beautiful Wellington, NZ.

  

  Putting that talk together reminded me about how far we have come in the last year both with the progress of WebRTC, its standards and browser implementations, as well as with our own small team at NICTA and our rtc.io WebRTC toolbox.

  

  One of the most exciting opportunities is still under-exploited : the data channel. When I talked about the above slide and pointed out Bananabread, PeerCDN, Copay, PubNub and also later WebTorrent, that’s where I really started to get Web Developers excited about WebRTC. They can totally see the shift in paradigm to peer-to-peer applications away from the Server-based architecture of the current Web.

  Many were also excited to learn more about rtc.io, our own npm nodules based approach to a JavaScript API for WebRTC.

  

  We believe that the World of JavaScript has reached a critical stage where we can no longer code by copy-and-paste of JavaScript snippets from all over the Web universe. We need a more structured module reuse approach to JavaScript. Node with JavaScript on the back end really only motivated this development. However, we’ve needed it for a long time on the front end, too. One big library (jquery anyone ?) that does everything that anyone could ever need on the front-end isn’t going to work any longer with the amount of functionality that we now expect Web applications to support. Just look at the insane growth of npm compared to other module collections :

  

  For those that – like myself – found it difficult to understand how to tap into the sheer power of npm modules as a font end developer, simply use browserify. npm modules are prepared following the CommonJS module definition spec. Browserify works natively with that and “compiles” all the dependencies of a npm modules into a single bundle.js file that you can use on the front end through a script tag as you would in plain HTML. You can learn more about browserify and module definitions and how to use browserify.

  For those of you not quite ready to dive in with browserify we have prepared prepared the rtc module, which exposes the most commonly used packages of rtc.io through an “RTC” object from a browserified JavaScript file. You can also directly download the JavaScript file from GitHub.

  

  So, I hope you enjoy rtc.io and I hope you enjoy my slides and large collection of interesting links inside the deck, and of course : enjoy WebRTC ! Thanks to Damon, JEeff, Cathy, Pete and Nathan – you’re an awesome team !

  On a side note, I was really excited to meet the author of browserify, James Halliday (@substack) at WDCNZ, whose talk on “building your own tools” seemed to take me back to the times where everything was done on the command-line. I think James is using Node and the Web in a way that would appeal to a Linux Kernel developer. Fascinating !!

  The post Progress with rtc.io first appeared on ginger’s thoughts.

• 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 %>

  Here is the movies helper code

  module MoviesHelper
  
  
  
     def mode(type)
  
        code = auto_logout
  
        if(code == true)
