Abstract: Techniques are described for adaptive encoding of different visual elements in a video frame. Characteristics of visual elements can be determined and used to set encoding parameters for the visual elements. The visual elements can be encoded such that one visual element is encoded differently than another visual element if they have different characteristics.

Abstract: Techniques are described for adaptive encoding different portions of media content based on content. Characteristics of GOPs of media content can be determined and used to set encoding parameters for the GOs. The GOPs can be encoded such that one GOP is encoded differently than another GOP if they have different characteristics.

Abstract: An adaptive video compression system may receive video data to be compressed, such as for delivery to a user device by a video streaming service. For example the video data may be an entire video file or a segment of a video file. The adaptive video compression system determines a suitable encoding scheme for compressing the video data. In order to determine the encoding scheme, the video data may be analyzed to extract a plurality of features interests of the video data, which may represent one or more characteristics of the video data. The features may be concatenated and collectively expressed as a feature vector. The feature vector is then used to determine a classification for the video data. Accordingly, an encoding scheme is determined for the video data based on the classification of the video data, and applied to video data to compress the video data.

Abstract: Disclosed are various embodiments for a client application for streaming media. The client application estimates the bandwidth of the client and the latency between the client and a media distribution service. A bit rate for a media stream is determined using the latency, a buffer state, and the estimated bandwidth. A time to send the request is determined using the estimated bandwidth and latency.

Abstract: Techniques are described that enable initiating playback of a media fragment before the entire fragment has been downloaded. Also described are techniques that enable a more granular approach to the way in which a client device requests and plays back media fragments.

Abstract: Techniques are described for encoding image frames of media content to be displayed within a three-dimensional projection space. Characteristics of the image frame when transformed to fit within the projection space can be determined and used to generate encoding parameters. The image frame can then be encoded using those encoding parameters, and therefore, improve the playback of the media content when it is displayed within the projection space.

Abstract: A technology is described for providing plotline information associated with media content. An example method may include receiving a request from a customer via an interface for plotline information stored on a data store. The plotline information may be included in media content where the plotline information may include a plurality of plotlines featured in the narrative of the media content. The plotline information may then be identified in the data store, and a graphical visualization of the plotline information included in the media content may be generated, where the graphical visualization may display the plotline information as corresponding to the narrative of the media content.
