Thank you for your kind reply. I found the link.
Upgrading the Kaltura Player version Library:
You can also change the player configuration manually and force a specific player to use the new Kaltura HTML5 Player V2 version. Use this option when the Upgrade to New Player option is not offered Kaltura (in the Universal studio). You will need to change the player UI Configuration.
Set up and Configure Kaltura V2 Library
Updating to the Kaltura HTML5 Player V2 is an easy operation and requires a few simple steps. This document applies for all releases but for ease of reading we will use v2.23. You can replace the version number with any current version at the time of reading.
Download HTML5 Player for older version of Kaltura Platform
If your Kaltura Platform version is older and doesn’t include the HTML5 studio, then the method above is not good for you and you need to change KMC configuration and re-deploy the KMC.
Check your KMC version in the base.ini configuration file. The KMC version is defined at kmc_version config.
This post applies for all KMC versions, but for ease of reading we will use v5.37.17.
Open the configuration file of the KMC.
Search for ‘html5′ string in the file and replace the HTML5 version with the new Kaltura HTML5 Player V2 version. Save the file.
Re-deploy the KMC:
php /opt/kaltura/app/deployment/uiconf/deploy_v2.php –ini=/opt/kaltura/web/flash/kmc/vX.XX.XX/config.ini
Clear the Kaltura cache and restart Apache:
sudo /etc/init.d/httpd restart.
