Abstract: In various examples, network conditions associated with a video stream are observed over time to determine a virtual scaling factor that may be applied to the images of one or more frames of the video stream to generate scaled images that may be appended with a padding region that maintains the original resolution of the video and/or video stream such that a receiving device may crop the padding region from the received video stream during the decoding process without restarting or including additional intra-coded frames.

Abstract: A performance metrics of a receiver is obtained using frames of an application hosted by a server that are received via a network. The one or more performance metrics include information indicative of a current occupancy of a frame buffer corresponding to the receiver and information indicative of a target occupancy of the frame buffer corresponding to the receiver. The frame buffer of the receiver is used to queue frames of the application for display. A frame rate associated with rendering at least one next frame of the application is adjusted using the one or more performance metrics of the receiver to control population of the frame buffer. Subsequent frames of the application hosted by the server are rendered using the adjusted frame rate. Upon rendering the subsequent frames, the server sends the subsequent frames to the receiver for display.
