A post processing system, method and computer program product content-adaptively transforms MPEG on-demand media streams, including a video optimizer software development kit (SDK); an application layer controlling the SDK interfacing with a mobile device operating and file system. Raw pixel frame buffers are parsed and structured. The buffers are normalizes for processing. Source content is analyzed in an uncompressed format for video patterns and characteristics and parameters are selected in a video codec output format. Estimated are parameters for portions and/or segments of the content. The content is recompressed and optimized in a content-adaptive manner to generate optimized content written into persistent storage of the mobile device, and segments of which are combined with an audio stream and/or a metadata stream information to generate a playable media stream in an ISO base media file format and/or a media file application specific format.

Method and system for real-time content-adaptive transcoding of video content on mobile devices to save network bandwidth during video sharing

A system, method and computer program product for real-time post-processing system that transforms MPEG-DASH on-demand media streams, including a DASH media player device; an intercepting media server device; a MPEG-DASH content origin server device; and a proxy media client device coupled to the DASH media player device and the intercepting media server device and configured to intercept MPEG-DASH HTTP requests from the DASH media player device and forward the intercepted requests to the intercepting media server device instead of the MPEG-DASH content origin server device. The intercepting media server device is configured to act as an HTTP proxy device, and forward the intercepted requests to the MPEG-DASH content origin server, and with each corresponding MPEG-DASH media subsegment acquired perform analysis of the video media content within the subsegment and apply selective transcoding.

Method and system for real-time transcoding of MPEG-DASH on-demand media segments while in transit from content host to dash client

A system, method and computer program product for improving video codec performance, including a pre-processing stage configured for downscaling by a variable amount an uncompressed video signal before sending such downscaled, uncompressed video signal to an input of a video codec; and a complimentary post-processing stage configured for upscaling the decompressed video signal received from an output of the video codec back to its original resolution before transmitting the decompressed video signal. The system, method and computer program product provides improved rate-distortion performance compared to direct use of the video codec alone.
