Abstract
A method for low-latency streaming of audio and video via a mobile computing device to facilitate a high-quality, real-time interactive streaming experience. The method includes receiving an application audio stream generated by execution of an application program, an application video stream generated by execution of the application program, a microphone audio stream, and a camera video stream. The application audio stream and the microphone audio stream are mixed to produce a mixed audio stream. The application video stream and the camera video stream are composited to produce a composited video stream. The mixed audio stream is encoded to produce an encoded audio stream, and the composited video stream is encoded to produce an encoded video stream. The encoded audio and video streams are packaged into one or more streaming packets, and output, to a remote computing device.
