A video-based monitoring system may dynamically adjust the resolution or frame rate of video cameras in a materials handling facility in response to changing conditions or events. The resolution or frame rate may be increased when an agent authorized to handle high-value items (e.g., expensive items or those at high risk of being stolen) enters the field of view of a given camera in the facility. The system (or a video camera thereof) may detect the presence of the authorized agent by detecting that his clothing or equipment includes a color or pattern designating such authorization using analytics applied to a video stream captured by the camera. Other pre-defined conditions or events indicating that higher-resolution video monitoring is warranted may trigger an increase in the resolution or frame rate of a camera. The resolution or frame rate may be decreased when these conditions or events no longer apply.

A policy is incorporated into a first set of policies at least in part by generating a second set of policies corresponding to the policy. An index of the first set of policies is generated based at least in part on a policy element of a normal form. Based at least in part on the index, a subset of the first set of policies that is relevant to at least one of a plurality of policy enforcement components is identified and provided to at least one of the plurality of policy enforcement components of a virtual resource provider identified as relevant. A request subject to the policy is received, and the policy is enforced at least in part by evaluating the request with respect to the subset of the first set of policies.

Techniques are described for facilitating interactions with device driver modules. In at least some situations, the techniques include managing interactions between device driver modules and other programs or hardware devices so as to minimize disruptions related to the device driver modules, including when changes to existing device driver modules are made. Such device driver module changes may have various forms and may occur for various reasons, including to install new versions of device driver modules or otherwise upgrade existing device driver modules. Furthermore, the interactions with device driver modules may be managed in various manners, including to allow changes to occur to a device driver module while that device driver module is in use on a computing system, but without causing other programs on the computing system to be restarted or to lose existing connections to the device driver module being changed.

A set of techniques is described for enabling a virtual machine based transcoding system. The system enables any transcoding provider to make their transcoding service available to other users over a network. The system can automate the deployment, execution and delivery of the transcoding service on behalf of the transcoding provider and enable other users to use the transcoding services to transcode content. The system receives a virtual machine image, transfers the image to a location where the media content is stored and creates a virtual private network of resources that will perform the transcoding of the media content. The virtual private network may be firewalled or otherwise restricted from opening connections with external clients when transcoding the content in order to prevent malicious use of the media content.

Systems and methods for providing object versioning in a storage system may support the logical deletion of stored objects. In response to a delete operation specifying both a user key and a version identifier, the storage system may permanently delete the specified version of an object having the specified key. In response to a delete operation specifying a user key, but not a version identifier, the storage system may create a delete marker object that does not contain object data, and may generate a new version identifier for the delete marker. The delete marker may be stored as the latest object version of the user key, and may be addressable in the storage system using a composite key comprising the user key and the new version identifier. Subsequent attempts to retrieve the user key without specifying a version identifier may return an error, although the object was not actually deleted.
