Abstract
In recent years, there has been a significant interest towards virtual reality applications, especially omnidirectional videos. Due to the huge resolutions, omnidirectional videos are difficult to codec and stream in term of traditional multimedia tools. In this paper, a view-dependent video encapsulation solution is proposed. Videos with different resolutions are partly extracted to combine to encapsulate mixed-resolution file according to user’s viewport, which can effectively save bandwidth without much noticeable quality impacts. Our solution results can decrease file size to 75% with a 110° × 110° viewport and provide full resolution video inside the FOV.
