You can install the Adaptive Media app from Liferay Marketplace for Liferay Portal CE 7.0 GA5+ or Liferay DXP. Search for Adaptive Media in the Marketplace and follow the app installation instructions at Using the Liferay Marketplace.

If you’re running Liferay Portal CE 7.0 GA6+ or Liferay DXP, then installing the Adaptive Media app is all you need to do. If you’re running Liferay Portal CE 7.0 GA5, however, then you must also install another module. The next section explains how to do this.

Installing Adaptive Media in Liferay Portal CE 7.0 GA5

If you’re running Liferay Portal CE 7.0 GA5, then you must install another module after installing the Adaptive Media app:

  1. Shut down your Liferay Portal server.

  2. Click here to download the module (it’s a JAR file).

  3. Copy the module into this folder of your Liferay Portal installation:

    [Liferay_Home]/osgi/marketplace/override/
    

    Create the override folder if it doesn’t exist.

  4. Start your Liferay Portal server. You should see these log messages during startup:

    INFO  [Start Level: Equinox Container: 60d02f03-ed0b-0018-179d-ebc04e65241e][LPKGBundleTrackerCustomizer:411] 
        Disabled Liferay CE Web Experience:/com.liferay.journal.service-3.17.3.jar
    INFO  [Start Level: Equinox Container: 60d02f03-ed0b-0018-179d-ebc04e65241e][DefaultLPKGDeployer:393] 
        Installed override JAR bundle  LPKG-Override::/liferay-ce-portal-7.0-ga5/osgi/marketplace/override/com.liferay.journal.service.jar
    

    These messages indicate that the new module has successfully replaced the old module.

  5. You can verify this by running the command lb "Journal Service" from the Gogo shell. It should indicate that the module is active:

    ID|State      |Level|Name
    524|Active     |   10|Liferay Journal Service (3.18.0.ADAPTIVE-MEDIA)
    

Well done! Next, you’ll learn which modules in the Adaptive Media app are mandatory or optional.

Adaptive Media’s Modules

Some modules in the Adaptive Media app are mandatory and must be enabled for Adaptive Media to function, while others can be disabled. The Adaptive Media API modules, which export packages for the other modules to consume, are mandatory; disabling one also disables any other modules that depend on it. Here’s a list of the Adaptive Media API modules:

  • Liferay Adaptive Media API
  • Liferay Adaptive Media Content Transformer API
  • Liferay Adaptive Media Image API
  • Liferay Adaptive Media Image Item Selector API

The Adaptive Media core modules are also mandatory, and must be enabled to ensure that Adaptive Media works as expected:

  • Liferay Adaptive Media Document Library
  • Liferay Adaptive Media Document Library Item Selector Web
  • Liferay Adaptive Media Document Library Web
  • Liferay Adaptive Media Image Content Transformer
  • Liferay Adaptive Media Image Implementation
  • Liferay Adaptive Media Image Item Selector Implementation
  • Liferay Adaptive Media Image JS Web
  • Liferay Adaptive Media Image Service
  • Liferay Adaptive Media Image Taglib
  • Liferay Adaptive Media Image Web
  • Liferay Adaptive Media Item Selector Upload Web
  • Liferay Adaptive Media Web

The Adaptive Media Blogs modules, which ensure that images uploaded to blog entries can be processed and adapted, are optional. Here’s a list of these modules:

  • Liferay Adaptive Media Blogs Editor Configuration
  • Liferay Adaptive Media Blogs Item Selector Web
  • Liferay Adaptive Media Blogs Web
  • Liferay Adaptive Media Blogs Web Fragment

The Adaptive Media Journal modules are optional. These modules apply Adaptive Media to web content articles:

  • Liferay Adaptive Media Journal Editor Configuration
  • Liferay Adaptive Media Journal Web

There are two more optional modules included in Adaptive Media:

  • Liferay Adaptive Media Image Content Transformer Backwards Compatibility: Ensures that content created before the Adaptive Media installation can use adapted images without the need to edit that content manually. It transforms the images both at startup and when a user views the content, which can negatively affect performance. We therefore recommend that you run some performance tests before using this module in production. You can disable this module if you don’t have old content, are experiencing performance problems, or your old content doesn’t need adapted images.

  • Liferay Adaptive Media Document Library Thumbnails: Lets thumbnails in Documents and Media use adapted images. For this to work, you must first migrate the original thumbnails to adapted images. We highly recommend that you enable this module, but it’s not mandatory.

Great! Now you know the mandatory and optional modules that come with Adaptive Media. The next section discusses the installation requirements for using animated GIFs with Adaptive Media. If you don’t need to use GIFs, you can skip ahead to the article on adding image resolutions to Adaptive Media.

Processing Animated GIFs

To process animated GIFs, Adaptive Media uses an external tool called Gifsicle. This tool ensures that the animation works when the GIF is scaled to different resolutions. You must manually install Gifsicle on the server and ensure that it’s on the PATH. Once it’s installed, you must enable it in Adaptive Media’s advanced configuration options.

If Gifsicle isn’t installed and image/gif is included as a supported MIME type in the advanced configuration options, Adaptive Media scales only a GIF’s single frame. This results in a static image in place of the animated GIF.
