Abstract: In various examples, a media stream may be received by a re-encode system that may leverage a recode engine to convert (e.g., at an interval, based on a request, etc.) an inter-frame associated with the media stream to an intra-frame. The intra-frame may be converted from the inter-frame using parameters or other information associated with and received with the media stream. The converted intra-frame may be merged into an updated segment of the media stream in place of the original inter-frame to enable storage of the updated segment—or a portion thereof—for later use.

Abstract: A codec architecture including an audio wave driver and a coded topology driver. The audio wave driver is communicatively coupled to an audio engine and an analog audio codec. The coded topology driver is communicatively coupled to the audio wave driver by a set of interfaces that enables streamlined code implementation, improved operation efficiency and power savings, while allowing vendors to supply differentiating functionality outside of the basic requirements of the operating system.
