Abstract
A method includes receiving a plurality of images at an encoder device. The plurality of images is encoded by the encoder device to generate an output video stream. The output video stream includes a plurality of encoded video frames corresponding to the plurality of images. While receiving the plurality of images and while generating the output video stream, the encoder device receives a notification that a particular image of the plurality of images satisfies a thumbnail generation condition based on stream analysis of one or more of the plurality of images. The output video stream is sent concurrently with a supplemental data package to a media server. The supplemental data package comprises a thumbnail and metadata associated with the thumbnail, the thumbnail generated from the particular image responsive to receiving the notification.
