    Abstract: In some aspects, the disclosure is directed to methods and systems for providing 360-degree video. One or more viewport engines receives 360-degree video data, and generates a plurality of versions of the 360-degree video data. Each version has a corresponding primary viewing direction, independently decodable units (IDUs) of video data arranged according to a sequence, and image resolution for the corresponding primary viewing direction that is higher than image resolutions for other viewing directions. A streaming server streams a first IDU of video content from a first version of the plurality of versions of the 360-degree video data to a client for rendering at the client, and receives feedback according to the rendering at the client. Responsive to the update in viewing direction, the streaming server dynamically switches to a second version of the plurality of versions that has a primary viewing direction comprising the second viewing direction.
