Hi @vinod_kumar1,
The SDKs available from https://developer.kaltura.com/api-docs/Client_Libraries are meant to be used against our own hosted ENV [i.e: www.kaltura.com or as it is sometimes knows - the Kaltura SaaS]. While when running Kaltura CE of the same version, they will most probably work correctly, you should instead generate clients by invoking the following from one of your Kaltura API servers:
# php /opt/kaltura/app/generator/generate.php <client name>
Where is one of the clients listed in /opt/kaltura/clients-generator/config/generator.all.ini.
That would ensure they are compatible with the Kaltura Server version you have deployed.
The post install scripts use the same method to generate the mandatory PHP clients, which are used by our various admin I/F as well as by the Kaltura Batch daemon.
Cheers,
