摘要： Techniques for resolution-based manifest generation for adaptive bitrate video streaming are described. As one example, a computer-implemented method includes performing a first, convex hull optimization on a video file for a first device resolution, performing a second, convex hull optimization on the video file for a second, lower device resolution, generating a first video representation for a point on both the first, convex hull optimization and the second, convex hull optimization for the first device resolution and the second, lower device resolution, generating a second video representation for a point only on the second, convex hull optimization for the second, lower device resolution, receiving a request for a manifest for the video file from a client device at the second, lower device resolution, generating the manifest for the client device that identifies the first video representation and the second video representation, and sending the manifest to the client device.
