Install and Configure Video Transcoding

1. In the installation package, locate the Web folder.
2. Copy the contents of the Webfolder into your Telligent Community site, merging existing folders.
   1. For example, if your website is located at c:/Web, it would end up containing c:/Web/vt and c:/Web/bin/Telligent.Evolution.VideoTranscoding.dll.

Install the Job Scheduler files

1. Stop the Job Scheduler service.
2. In the installation package, locate the Tasks folder.
3. Copy the contents of the Tasksfolder to the root of your Job Scheduler installation.
   1. For example, if your Job Scheduler root was c:/Tasks, it would end up containing c:/Tasks/ffmpeg and c:/Tasks/Telligent.Evolution.VideoTranscoding.dll.

Modify the Web configuration files

1. In your Telligent Community site, locate a file named communityserver_override.config and edit it  in any text editor.
   1. Note that by default, your site does not have this override file. If your site does not have it, you can create a file named communityserver_override.configin the root of your web installation and then inside, add the following:

      <?xml version="1.0" encoding="utf-8"?>
      <Overrides>
        <!-- Add any needed overrides here -->
      </Overrides>

2. Add the following information between the <Overrides /> tags:

   <Override xpath="/CommunityServer/FileViewers" mode="add" where="end">
     <add type="Telligent.Evolution.VideoTranscoding.FileViewer, Telligent.Evolution.VideoTranscoding" 
       extensions="3gp;avi;flv;m4v;mkv;mov;mp2;mp4;mpeg;mpg;ogv;webm;wmv" />
   </Override>
   <Override xpath="/CommunityServer/CentralizedFileStorage" mode="add" where="end">
     <fileStore name="videotranscoding" 
       type="Telligent.Evolution.Extensibility.Storage.Providers.Version1.FileSystemFileStorageProvider, Telligent.Evolution.Components" 
       basePath="~/filestorage/" />
   </Override>
   <Override xpath="/CommunityServer/MimeTypes" mode="add" where="end">
       <mimeType extensions="webm" mimeType="video/webm" />
   </Override>

Modify the Job Scheduler configuration files

1. In your Job Scheduler installation directory site, locate a file named communityserver_override.config  and edit it  in any text editor.
   1. Note that by default, your scheduler does not have this override file. If scheduler does not have it, you can create a file named communityserver_override.configin the root of your web installation and then inside, add the following:

      <?xml version="1.0" encoding="utf-8"?>
      <Overrides>
        <!-- Add any needed overrides here -->
      </Overrides>

2. Add the following information between the <Overrides />tags:

   <Override xpath="/CommunityServer/CentralizedFileStorage" mode="add" where="end">
     <fileStore name="videotranscoding" 
       type="Telligent.Evolution.Extensibility.Storage.Providers.Version1.FileSystemFileStorageProvider, Telligent.Evolution.Components" 
       basePath="ABSOLUTE\PATH\TO\WEB\FILESTORAGE" />
   </Override>
   <Override xpath="/CommunityServer/CentralizedFileStorage/fileStore[@name='Telligent.Evolution.Components.Attachments']" 
       mode="change" name="basePath" value="ABSOLUTE\PATH\TO\WEB\FILESTORAGE" />
   <Override xpath="/CommunityServer/CentralizedFileStorage/fileStore[@name='Telligent.Evolution.Components.Attachments.Temporary']"
       mode="change" name="basePath" value="ABSOLUTE\PATH\TO\WEB\FILESTORAGE" />
   <Override xpath="/CommunityServer/CentralizedFileStorage/fileStore[@name='CommunityServer.Components.ImageFileViewer']"
       mode="change" name="basePath" value="ABSOLUTE\PATH\TO\WEB\FILESTORAGE" />
   <Override xpath="/CommunityServer/CentralizedFileStorage/fileStore[@name='CommunityServer.Components.MultipleUploadFileManager']"
       mode="change" name="basePath" value="ABSOLUTE\PATH\TO\WEB\FILESTORAGE" />
   <Override xpath="/CommunityServer/CentralizedFileStorage/fileStore[@name='CommunityServer.MailGateway.MailRoom.ForumsHandler']"
       mode="change" name="basePath" value="ABSOLUTE\PATH\TO\WEB\FILESTORAGE" />
   <Override xpath="/CommunityServer/CentralizedFileStorage/fileStore[@name='CommunityServer.Components.PostAttachments']"
       mode="change" name="basePath" value="ABSOLUTE\PATH\TO\WEB\FILESTORAGE" />
   <Override xpath="/CommunityServer/CentralizedFileStorage/fileStore[@name='CommunityServer.Components.SiteFiles']"
       mode="change" name="basePath" value="ABSOLUTE\PATH\TO\WEB\FILESTORAGE" />
   <Override xpath="/CommunityServer/CentralizedFileStorage/fileStore[@name='CommunityServer.Blogs.Components.WeblogFiles']"
       mode="change" name="basePath" value="ABSOLUTE\PATH\TO\WEB\FILESTORAGE" />
   <Override xpath="/CommunityServer/CentralizedFileStorage/fileStore[@name='CommunityServer.Components.UserFiles']"
       mode="change" name="basePath" value="ABSOLUTE\PATH\TO\WEB\FILESTORAGE" />
   <Override xpath="/CommunityServer/CentralizedFileStorage/fileStore[@name='CommunityServer.Wikis.Components.Files']"
       mode="change" name="basePath" value="ABSOLUTE\PATH\TO\WEB\FILESTORAGE" />
   <Override xpath="/CommunityServer/CentralizedFileStorage/fileStore[@name='CommunityServer.Discussions.Components.Files']"
       mode="change" name="basePath" value="ABSOLUTE\PATH\TO\WEB\FILESTORAGE" />

3. Alter all mentions of "ABSOLUTE\PATH\TO\WEB\FILESTORAGE" to be your physical path to the filestoragefolder, e.g.,

   <Override xpath="/CommunityServer/CentralizedFileStorage/fileStore[@name='CommunityServer.Discussions.Components.Files']"
     mode="change" name="basePath" value="c:\path\to\filestorage" /> 

4. While still in your Job Scheduler installation directory, locate and edit the tasks.config file in a standard editor.
5. Add the following job node as a child node of the jobs/cron/jobs node:

   <job schedule="0 */2 * * * ? *" type="Telligent.Evolution.VideoTranscoding.TranscodingJob, Telligent.Evolution.VideoTranscoding"/>

   1. By default, this job will run every two minutes. You can adjust the schedule to suit your needs.
6. Restart your IIS application pool. However, DO NOT start the Job Scheduler until after configuration is complete within your Telligent Community site as instructed in the next section.

Configuration

1. Log into your Telligent Community site as an administrator and navigate to Control Panel > System Administration > Site Administration > Site Configuration > Manage Plugins. Locate the Video Transcoding plugin, HTML5 Video Transcoding.
2. Click Configure and set the properties on all three tabs according to the following table.
   
   

   Option	Description
   Maximum width	The maximum width (in pixels) at which the video will be transcoded from its source.  If the source video is wider, it will be scaled down retaining its original aspect ratio. If the source video is narrower, it will not be up-scaled. This does not influence the playback size, which is still governed by the theme. default: 1024
   Maxiumum height	The maximum height (in pixels) at which the video will be transcoded from its source. If the source video is taller, it will be scaled down retaining its original aspect ratio. If the source video is shorter, it will not be up-scaled. This does not influence the playback size, which is still governed by the theme. default: 768
   Video bitrate	The maximum video bitrate (in kbps) at which the source video will be transcoded.  default: 768
   Audio bitrate	The maximum audio bitrate (for both channels combined, in kbps) at which the source video's audio will be transcoded. default: 128
   Stereo	Determines whether the transcoded video will retain both audio channels (if it has two) or just one. default: checked
   Poster second	The point in the video's playback (at that second) where it takes a screenshot for displaying as the video's preview and thumbnail. default: 5
   Show Basic Viewer while Queued	When selected, videos that have been uploaded and scheduled to transcode but have not yet begun to transcode will render via the classic, default, video file viewer included with Evolution.  This is useful when a large backlog of videos is expected.  default: false
   Encoding timeout	The timeout (in seconds) at which the video transcoder should quit if it has not completed transcoding a given video. default: 1800
   Progress handler	If the installation instructions were followed correctly, this should not need to be changed from its default. It defines the path to the /vt/ directory copied to the /Web during installation in case this differs from the default. default: ~/vt/transcodingprogress.ashx

3. Save the configuration.
4. Select the check box next to the Video Transcoding plugin to enable it, then click Save at the bottom of the plugin page.
5. You can now start your Telligent Job Scheduler service.
