• FFMPEG JNI wrapper causes Android app exit

  5 décembre 2013, par user3043703

  I'm writing a JNI wrapper to use FFMPEG as a library in my Android project. I'm mainly using as references the halfninja project (and some forks) and this useful guide. I'm making a lot of personalizations but I got a working version with some additional codecs, the only problem is that, after FFMPEG ends, it causes my application to quit with no errors and I'd like to avoid this (for example to invoke FFMPEG again). Looking at the halfninja wrapper, the line of code exit(ret) ; from the cmdutils.c file is commented in the function void exit_program(int ret) but if I do the same with the latest (2.1.1) version of FFMPEG it causes me a signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr 6f632494 error. My code looks like this :

  void exit_program(int ret)
  
  {
  
     if (program_exit)
  
        program_exit(ret);
  
  
  
     //exit(ret);
  
    //if I uncomment this the app automatically exits without errors
  
  }

  I see that both my references are a little old, also refering to a very old release of FFMPEG and it seems that meanwhile the source code changed a lot. I invoke FFMPEG through the JNI wrapper inserted in a new thread in the application code.

  All I'd like to know is : there's a way to avoid the automatic exit of my application after the end of FFMPEG thread ?

• 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

• Do I need to install FFMPEG.exe on Windows local server to use it in PHP & Xampp ? [on hold]

  5 juillet 2016, par Drupalist

  I need to use FFMPEG in PHP on my localhost (windows 7) to convert videos. In Install FFMPEG on XAMPP and somewhere else, it has been explained how to install and configure FFMPEG on Xampp.

  I tried these solutions but I still get the following error from Apache.

  PHP Startup:FFMPEG : Unable to initialize module

  Module compiled with module API = 20090626

  PHP compiled with module API = 20121212

  These options need to match

  I would like to know do I need to install FFMPEG.exe on my computer ?
