Synchronized combinations of captured real-time media content with played-back digital content

A system comprising:

• a multimedia device that includes a memory storing program instructions for generating combined media content, and that includes one or more processors configured to execute the program instructions, which when executed, cause the multimedia device to:
• continuously during operation of a source device:
• receive a media content stream from the source device;
• buffer a most recent portion of the media content stream;
• and
• provide the media content stream to a sink device configured to playback the media content stream to a user of the multimedia device;
• receive one or more messages from a media capture device associated with a capture, by the media capture device, of a first media clip;
• based on the one or more messages, identify a portion of the most recent portion of the media content stream that is buffered, and extract the portion therefrom to generate a second media clip;
• generate the combined media content by combining first media content of the first media clip and second media content of the second media clip;
• and
• share the combined media content with a device over a network.

A computer-readable storage medium having program instructions recorded thereon that, when executed by a processing device, perform a method, for generating combined media content, that comprises:

• continuously performing by a multimedia device:
• receiving a media content stream from a source device;
• buffering a most recent portion of the media content stream;
• and
• providing the media content stream to a sink device configured to playback the media content stream to a user of the multimedia device;
• receiving one or more messages from a media capture device associated with a capturing, by the media capture device, of a first media clip;
• based on the one or more messages, identifying a portion of the most recent portion of the media content stream that is buffered, and extracting the portion therefrom, generating a second media clip;
• generating the combined media content by combining first media content of the first media clip and second media content of the second media clip;
• and
• sharing the combined media content with a device over a network.
