A streaming composition system is described herein that provides easy workflow and playback capabilities for content producers to create composite media assets from existing and on-going media content and for streaming clients to seamlessly playback composite multimedia streams provided from different sources. These assets provide broadcasters an option to quickly turn around highlights for an on-going event. The streaming composition system allows a producer to identify clips within existing media assets and compose the clips into a new unified streaming presentation. For producers that already have smooth streaming media assets, the system leverages these assets to provide seamless playback across clip boundaries including advanced playback support for advertisement insertion, fast forward, rewind, and so on.

Seamless playback of composite media

Audio tracks may be added to a live video stream using one or more mixers that may decode the audio from a video stream, mix an additional audio stream, and encode the mixed audio stream. The system may make the new audio stream available for live download by consumers. The mixers may include a video playback mechanism to view the live video stream, as well as an audio capture and mixing system that may create a new audio track that may be synchronized with the video stream using timestamps. A consumer device may download and consume the video with the new audio track on a slight delay from the live video stream.
