Transcoding a video stream to facilitate accurate display

摘要

Disclosed are various embodiments for transcoding a video stream to facilitate accurate display. An uncompressed video stream comprising a sequence of video frames is obtained. An encoded reverse order video stream is generated from the uncompressed video stream in one embodiment. In another embodiment, the uncompressed video stream includes multiple views, and a compressed video stream is generated from the uncompressed video stream. The compressed video stream excludes one or more of the views.

主权项

1. A system, comprising:
a video processing device including at least one circuit, the video processing device being configured to:
obtain an uncompressed video stream comprising a sequence of video frames including both a left-eye view and a right-eye view from a compressed video stream;generate an encoded reverse order video stream including one of the left-eye view or the right-eye view and excluding the other of the left-eye view or the right-eye view, the encoded reverse order video stream generated from the uncompressed video stream by:
storing a portion of the sequence of video frames in a buffer;encoding the portion of the sequence of video frames in a reverse order using video encoder logic; andoutputting the encoded portion of the sequence of video frames in the reverse order; andgenerate a video signal that concurrently renders the sequence of video frames in a forward order and the sequence of video frames in the reverse order;wherein the compressed video stream is compressed using a first group-of-pictures (GOP) length, and the encoded reverse order video stream is compressed using a second GOP length.
