For each frame in the video, a corresponding transform operation is first computed based on an estimated camera movement. Next, the video is segmented into multiple video segments and the corresponding per-frame transform information for the multiple video segments. The video segments are then distributed to multiple processing nodes that perform the image stabilization of the corresponding video segment by applying the corresponding transform. The results from all the stabilized video segments are then stitched back together for further video encoding operation. |

Transport path-aware quality of service for mobile communications
Embodiments provide quality of service for media content delivery over capacity-constrained communications links to user devices by exploiting usage models and path awareness. For example, one or more uncongested beams can be identified as preceding one or more congested beams (e.g., by computing a congestion map) along a predicted transport path of a user device moving through a multi-beam satellite communications system. A prediction can be made aps to one or more future requests that are likely to be made by the user device for pre-positionable types of media content, and that are likely to be serviced by one of the subsequent congested beams. When such a request for pre-positionable media content is predicted, embodiments can schedule transmission of at least a portion of the media content over one or more of the preceding uncongested beams for storage local to the user device, thereby pre-positioning the content at the client prior to reaching the congested beam. |

Dynamically adjusting a data compute node group
Some embodiments provide a novel method for load balancing data messages that are sent by a source compute node (SCN) to one or more different groups of destination compute nodes (DCNs). In some embodiments, the method deploys a load balancer in the source compute node's egress datapath. This load balancer receives each data message sent from the source compute node, and determines whether the data message is addressed to one of the DCN groups for which the load balancer spreads the data traffic to balance the load across (e.g., data traffic directed to) the DCNs in the group. When the received data message is not addressed to one of the load balanced DCN groups, the load balancer forwards the received data message to its addressed destination. On the other hand, when the received data message is addressed to one of load balancer's DCN groups, the load balancer identifies a DCN in the addressed DCN group that should receive the data message, and directs the data message to the identified DCN. To direct the data message to the identified DCN, the load balancer in some embodiments changes the destination address (e.g., the destination IP address, destination port, destination MAC address, etc.) in the data message from the address of the identified DCN group to the address (e.g., the destination IP address) of the identified DCN. |
