Abstract
Methods, systems, and computer readable media can be operable to facilitate the generation of a continuous multimedia stream during trickplay operations. When a trickplay request is received by a device that is processing a video stream for delivery to a media player, the device may modify the video stream to create a seamless delivery and playback of the underlying content at the media player. In response to a trickplay request such as a pause request or seek request, the device may identify a seek target based on the request and may initiate a new video stream that begins at the identified seek target. The device may further modify the new stream by trimming from the stream any content that is already stored or cached at the media player, thereby creating a video stream without any discontinuities.
