Creation of media clips from media broadcasts

A media sharing system receives a media stream from a broadcaster system. The media sharing system streams a transcoded version of the media stream to user devices that request the media stream broadcast. Additionally, as the media stream is received from the broadcaster system, the media sharing system generates media segments that include the content of the media stream. Based on programming information received for the media stream, the media sharing system creates a media clip for each program included in the media stream. The media sharing system uses content from the media segments to generate the media clips. Further, as a user is viewing a media stream broadcast to the user's device by the media sharing system, the user may request the creation of a media clip from the media stream. The system identifies media segments that include content of the desired media clip and creates the media clip.
