Telstra, Australia’s top telecommunications company, has invested $43 million in online-video platform provider Ooyala.

The investment — which brings Ooyala to $122 million raised to date — comes after Telstra led Ooyala’s $35 million series E funding round in June 2012 and signed a reseller agreement with the company.

Ooyala said it will use the new funding to accelerate engineering efforts focused on video streaming and analytics. Other investors include Sierra Ventures, Rembrandt Venture Partners, CID Group and EDB Investments.

Customers of Ooyala, based in Mountain View, Calif., include ESPN, Bloomberg, Univision, Viacom’s Comedy Central, Shine Australia, Major League Soccer, The British Film Institute and the PGA Tour.
