Enable RTMP delivery

1. Set the RTMP URL on kConfLocal.php
   vim /opt/kaltura/app/alpha/config/kConfLocal.php
   Change “rtmp_url” => “YourSite/oflaDemo” (line 17)
2. Edit the playManifest to use red5 server for RTMP

   vim /opt/kaltura/app/alpha/apps/kaltura/modules/extwidget/actions/playManifestAction.class.php

3. Mark line #524
   // $baseUrl = myPartnerUtils::getRtmpUrl($partnerId);
4. Add the following instead:
   $baseUrl = “rtmp://YourSite/oflaDemo”;
   Mark lines (531 – 534)
5. Add these code lines below the marked code:

   $key = $flavorAsset->getSyncKey(flavorAsset::FILE_SYNC_FLAVOR_ASSET_SUB_TYPE_ASSET);
   $fileSync = kFileSyncUtils::getLocalFileSyncForKey($key);
   if(!$fileSync)
   continue;
   $urlManager->setClipTo($this->clipTo);
   $urlManager->setFileExtension($flavorAsset->getFileExt());
   $urlManager->setProtocol(StorageProfile::PLAY_FORMAT_RTMP);
   $url = $urlManager->getFileSyncUrl($fileSync);

6. Enable Red5 to follow soft links – fixes the “media not found issues”
   vim /usr/share/red5/conf/context.xml
7. Add this inside the content object:
   <Context path=”/oflaDemo” allowLinking=”true”/>
8. Restart red5 server
   service red5 restart
9. Test RTMP
   Go into partner account -> preview and embed -> select RTMP and play the video

Enable Live Streaming

1. Adjust Provisioning Code
   vim /opt/kaltura/app/batch/batches/Provision/Engines/KProvisionEngineAkamai.php
2. Comment everything from
   $flashLiveStreamInfo = $this->streamClient->provisionFlash… (lines 56 – 88)
   Until the return line (not including the return line)
3. Paste the following before the return line:

   $data->streamID = 'livestream';
   $data->backupStreamID = $data->streamID;
   $data->streamName = $job->entryId . '_%i@' . $data->streamID;
   $data->rtmp = 'rtmp://YourSite/oflaDemo';
   $data->primaryBroadcastingUrl = 'rtmp://YourSite/oflaDemo';
   $data->secondaryBroadcastingUrl = 'rtmp://YourSite/oflaDemo';
   $data->encoderUsername = '';

4. Change stream clipper

   vim /opt/kaltura/app/alpha/apps/kaltura/modules/extwidget/actions/streamclipperAction.class.php

   Change $streamer = “rtmp://YourSite/oflaDemo”; (line 24)

5. Test live stream
   Create a new live stream (KMC->content->new live stream)
   Add the stream name into your streaming appliocation for example: Flash Media Live Encoder
6. Create a page with embedded live stream player
7. Use any encoder for example Adobe FME (Windows and Mac) – and broadcast your live stream.
8. Connect to the live stream using the page you created at step 6
