The transcoding of a contribution feed into a plurality of output feeds in various formats can be monitored to ensure that unnecessary data is not transmitted in the contribution feed. Each output feed can be transcoded using respective values for a set of video format parameters. These values can be aggregated and analyzed to determine the lowest values for individual parameters that are being used for the various output feeds. A video encoder for the contribution feed can then dynamically modify the video format parameters used to encode the contribution feed in order to avoid encoding and transmitting data that is not actually used for these output streams, which can conserve resources such as network bandwidth, or enable those resources to be used more advantageously to send data that will actually result in higher quality video presentation in the output formats for current limitations or conditions.

Dynamic encoding parameter adjustment

Techniques for on-demand issuance of private keys for encrypted video transmission are described. A video processing service of a provider network receives a request from a computing device outside the provider network to begin video processing of video data generated by a video source device outside the provider network. The video processing service sends instructions to a video encoding device associated with the video source device to establish the connection for video transmission. The video processing service sends an encryption key to the video encoding device, and sends a decryption key to a video decryption engine. Subsequently, the video processing service receives video data from the video source device, via the video encoding device.

A contribution encoder receives media from a source, encodes the media, and transmits the encoded media to a network-adaptive encoding system for eventual distribution to end users. The network-adaptive encoding system tests a network connection between the contribution encoder and the network-adaptive encoding system before transmission of the encoded media begins. The network-adaptive encoding system uses the results of the test to select appropriate values for parameters that define the encoding and transmission of the media. The selected parameter values are transmitted by the network-adaptive encoding system to the contribution encoder for use in encoding and transmitting the media.

A system and method for management of bandwidth shared by a plurality of video content encoders is provided. A management service coordinates an unequal allocation of available bandwidth among a set of encoding nodes. The management service can receive measured bandwidth attributes from a plurality of encoding nodes to determine a total available bandwidth. The management service can then allocate the available bandwidth based by applying allocation criteria that can include performance criteria, financial criteria or other prioritization criteria. The management service can then transmit the allocated bandwidth to the encoding nodes.

A management service coordinates an unequal allocation of available bandwidth among a set of encoding nodes. A management service can receive measured bandwidth attributes from a plurality of encoding nodes to determine a total available bandwidth. The management service can receive measured bandwidth attributes from a plurality of encoding nodes that is transmitted to the management service in accordance with an IoT based messaging protocol. The management service can then allocate the available bandwidth based on different criteria. The management service can then transmit the allocated bandwidth to the encoding nodes using the IoT based messaging protocol.

Managing video encoders utilizing IoT-based communications

Techniques for adapting source ports for traffic include generating a first packet with a header and a payload, the header including an indication of a first source port from which the first packet is to be transmitted. The first packet is transmitted to a receiver using the first source port and, upon not receiving an acknowledgment from the receiver, a second packet with second header and the same payload is generated. The second header includes an indication of a second, different source port from which the second packet is to be transmitted. The second packet is transmitted to the receiver using the second, different source port. An acknowledgment is received from the receiver for one of the first or second packets, and the acknowledgment includes an indication of the source port that sent the packet.

On-demand issuance private keys for encrypted video transmission

Techniques are described enabling users to transfer the association of a cloud-managed video encoding or decoding device from one region of a cloud provider network to another. A video processing service of a cloud provider network enables users to purchase video encoding or decoding devices that can be used to encode and reliably transfer video content to the video processing service from locations of the users' choice. The video processing service receives a request to transfer the association of a video encoding or decoding device from one region of the cloud provider to another and the video processing service executes workflows that enable the association of a video encoding or decoding device to be transferred to one region from another.

Transferring video encoding or decoding devices across regions of a cloud provider network

A video packaging and origination service can include one or more encoder components that receive content for encoding and transmitting to requesting entities. During the operation of the encoder components, individual encoders receive input signals for encoding and determine quality metric information related to the generation of an encoded segment. The encoder components exchange quality metric information and an encoder component is selected to transmit an encoded segment. The selection of an individual encoder component per segment can continue throughout the streaming process.

A content delivery service that facilitates the selection of virtual machine instances utilized to implement the transcoding function. A management service first implements a test channel configuration routine that selects worst case scenario configurations for implementing the transcoding function and measures performance metrics for different virtual machine instances implementing the transcoding function. The management system can then match incoming requests for video channel transcoding with signature data from the test channel configurations to identify which virtual machine instances can implement the requested transcoding functionality.

A first video frame is received from a video source, the first video frame having a first pixel value at a first frame location of a plurality of frame locations, wherein the first frame location includes a horizontal pixel location and a vertical pixel location. A second video frame is received from the video source, the second video frame having a second pixel value at the first frame location. The first frame location is identified based at least in part on determining a difference between the first pixel value and the second pixel value. A package including a pixel update value and an indication of the first frame location is sent to a video destination, wherein the pixel update value is based at least in part on the second pixel value.
