Abstract

ABSTRACT Video decoding may be performed by either hardware or software, wherein the compressed data is restored to a visible image for display to a user. In both cases, uncompressed data from the decoder is typically not saved to a file prior to the uncompressed data being rendered by a video renderer in a graphics processing unit (GPU), as the data is rendered onto the video memory and not returned to the decoder. To save the uncompressed data, a filter may be connected between a video decoder and a video renderer. The filter captures the uncompressed data, and may save it to a file on the hard drive, for example.
