An increasing number of social media apps such as Instagram, Snapchat and Messenger are using video features. With modern Android devices having enough processing power to run video processing algorithms locally, there's no need to send videos through expensive internet bandwidth to be processed on the backend. Overlays, transcoding and cropping are just a few of the challenges you face when working with video on-device. In this talk I will go through my experience experimenting with built-in as well as third party libraries for video manipulation on Android. We will look at the benefits of two leading media processing libraries, and how you can leverage them to enhance Android's native MediaCodec API to accomplish these tasks. You will walk away with a head start on how to tackle the most common challenges with videos on Android.
