Paytm Insider. Interactive live video for India's largest ticketing platform.
PayTM Insider is India's largest online ticketing and events company. Insider approached nilenso with a pioneering concept for its time: to take their live, interactive events online.
We worked with Insider to build a digital platform for live events, with the objective of “streaming interactive video to one million concurrent users”.
The pilot was a real-time quiz that thousands of users would participate in. In addition to all the challenges that come with live video, we had to ensure that all participants received the questions at the same time.
Our solution involved a dashboard from where a producer could run the quiz, publish questions and answers to a massive live audience, and coordinate transitions from one question to the next.
We also built video transcoding into the platform using mimoLive and Wowza Cloud, so the live video stream from the quizmaster could be streamed to all participants.
The quiz and video were synchronized by stamping metadata onto the stream, self-identifying sync time, and compensating for server-side transcoding delays on mobile clients.
In order to load test the system, we built a Mob Simulator, that simulated hundreds of thousands of concurrent users.
The service was transitioned to an in-house team over months, while coaching them on Elixir, and OTP as well.
