Various types of objects or occurrences can be automatically detected in input media being processed using a transcoder. The media content can be analyzed to determine various transitions, such as scene changes, which provide insight into useful locations for performing object recognition. Representative frames subsequent a transition are analyzed to determine whether they are appropriate for image analysis, using factors such as amount of motion, brightness, color, or pixel disparity within the frame. If a representative frame meets the various criteria, that frame is sent to an object recognition service for analysis. The output of the service can be a set of object tags that provide information identifying the object and its location in the media. The output tags can be encoded into the output video or stored to an associated metadata file, among other such options.

Automated indexing of media content

A method is disclosed for the decoding and encoding of a block-based video bit-stream such as MPEG2, H.264-AVC, VC1, or VP6 using a system containing one or more high speed sequential processors, a homogenous array of software configurable general purpose parallel processors, and a high speed memory system to transfer data between processors or processor sets. This disclosure includes a method for load balancing between the two sets of processors.

Video encoding and decoding using parallel processors

Methods, systems, and computer-readable media for monitoring of media pipeline health using tracing are disclosed. At a plurality of stages of a media delivery pipeline, tracing metadata is generated for elements of a media stream. The tracing metadata comprises a content identifier, a segment identifier, and a stage identifier. The tracing metadata is generated from the plurality of stages and sent to a metadata repository using instrumentation of components that implement the plurality of stages. A problematic stage within the plurality of stages is identified based at least in part on analysis of the tracing metadata.

Methods, systems, and computer-readable media for unicast routing of a media stream to subscribers are disclosed. A stream routing service is implemented using one or more computing devices that are provisioned from a multi-tenant provider network. The service acquires a media stream over one or more input channels from a media source. The service replicates the media stream to a plurality of subscriber components that have subscribed to the media stream. The media stream is replicated to the subscriber components using unicast transmission to individual addresses of the subscriber components.

Unicast routing of a media stream to subscribers

A system comprising a broadcast facility, one or more players, and an analytic service center. The broadcast facility may be configured to provide a plurality of streams. The one or more players may be configured to receive at least one of the plurality of streams and provide feedback on a user experience. The analytic service center may be configured to receive the feedback from the one or more players.

Adjusting network operations based on user feedback

A system including one or more cloud computing units and a ground unit. The one or more cloud computing units may be configured to process video content. The ground unit may be configured to pre-process the video content and deliver the video content to the one or more cloud computing units.

Heterogeneous video processing using private or public cloud computing resources

A method for invalidating content segments of a bitstream. The method comprises a step of delivering a manifest file from an origin server to a content delivery network. The manifest file may have a time-to-live value and may be redelivered based on the time-to-live value. The method comprises a step of delivering one or more content segments from the origin server to the content delivery network. The manifest file may contain pointers to the content segments. The method comprises a step of modifying the manifest file at the origin server to include invalidation information based on an input signal. The method comprises a step of invalidating the content segments throughout the content delivery network based on the invalidation information.

Content delivery network video content invalidation through adaptive bitrate manifest manipulation

An apparatus includes a processor, a graphics processing unit and a memory. The memory stores computer executable instructions. The computer executable instructions include a motion estimation kernel which when executed by the graphics processing unit performs motion estimation on a current frame using a reference frame. The current frame and the reference frame are stored in a globally shared memory of the graphics processing unit.

Video encoder using GPU

An apparatus including a graphics processing unit, a processor and a memory. The memory stores computer executable instructions. The computer executable instructions, when executed by the processor, configure the graphics processing unit to store a current frame, at least one reference frame, and a reconstructed frame in a globally shared memory of the graphics processing unit.

An apparatus comprising a graphics processing unit, a processor and a memory. The memory stores computer executable instructions. The computer executable instructions use (i) the graphics processing unit to perform prediction, decimation, transformation and quantization, and inverse-quantization and inverse-transformation and (ii) the processor to perform entropy encoding and rate control.

Techniques are disclosed for employing a set of stream processors to greatly accelerate common video encoding and transcoding tasks, with the goal of making these tasks run at a reasonable rate on off-the-shelf hardware. Stream processors are most commonly found in the graphics processing unit (GPU), a commodity piece of computer hardware used to generate images for display. Embodiments of the invention are particularly advantageous to accelerate video encoding and transcoding tasks in which the blocks being processed have dependencies on their neighboring blocks.
