A hardware encoder includes a chassis including at least one vent cut into a first surface of the chassis. The hardware encoder further includes an input interface disposed within the chassis and configured to receive a media signal. The hardware encoder further includes encoding circuitry disposed within the chassis and configured to encode the media signal to generate a media stream. The hardware encoder further includes a network interface disposed within the chassis and configured to send the media stream to a publishing destination. The hardware encoder further includes a bezel attached to the first surface of the chassis and enabling a view of a display screen. A portion of the bezel extrudes in a direction away from the first surface to enable airflow into the at least one vent.

Hardware encoder

A method includes receiving an input media stream at a hardware encoder. The method also includes executing, at a processor of the hardware encoder, a headless browser to retrieve an instance of a dynamic web page that includes additional content. The method also includes storing the additional content at a memory that is accessible to the processor and encoding circuitry of the hardware encoder. The method further includes retrieving, at the encoding circuitry, the additional content from the memory and encoding the input media stream to generate an output media stream. At least one frame of the output media stream includes at least a portion of the additional content in conjunction with at least a portion of a corresponding frame of the input media stream.

Media streaming using a headless browser

A method includes reducing, at an encoder, an encoding bit rate of video data in response to a first indication of available bandwidth for transmission of the encoded video data. The method includes reducing an encoding frame size of the video data in response to the encoding bit rate falling below a first threshold. The method also includes increasing the encoding bit rate in response to a second indication of the available bandwidth. The method further includes increasing the encoding frame size in response to the encoding bit rate rising above a second threshold. The second threshold is greater than the first threshold.

Adjusting encoding frame size based on available network bandwith

Adjusting encoding frame size based on available network bandwidth

A hardware encoder includes a network interface configured to receive configuration information via a private network and a processor configured to encode at least one media stream based on the configuration information. The configuration information is received from a mobile device connected to the private local network.

A method includes receiving a media stream and generating first and second encoded versions of the media stream, the first encoded version associated with a first key frame interval and the second encoded version associated with a second key frame interval greater than the first key frame interval. The method also includes receiving, from a destination device, a request to generate a media clip, the request identifying a start point. The method further includes generating the media clip based on first sequence of frames of the first encoded version and second sequence of frames of the second encoded version. The first sequence begins at a first frame corresponding to the start point and ends at a second frame corresponding to a transition point. The second sequence begins at a third frame following the transition point and ends at a fourth frame corresponding to a stop point.

Clip generation based on multiple encodings of a media stream

A method includes detecting, at an interceptor device, a transmission of an encrypted media stream from a first device to a second device. The method also includes intercepting the encrypted media stream, during the transmission, for a simulcast operation associated with the encrypted media stream. The transmission of the encrypted media stream from the first device to the second device is substantially unaffected by the interception. The method further includes simulcasting a version of the encrypted media stream to at least a third device in response to intercepting the encrypted media stream.

Media stream interception and simulcast

A method includes receiving a media stream and generating first and second encodings of the media stream, the first encoding associated with a first key frame interval and the second encoding associated with a second key frame interval greater than the first key frame interval. The method also includes receiving, from a destination device, a request to generate a media clip, the request identifying a start point. The method further includes generating the media clip based on first sequence of frames of the first encoding and second sequence of frames of the second encoding. The first sequence begins at a first frame corresponding to the start point and ends at a second frame corresponding to a transition point. The second sequence begins at a third frame following the transition point and ends at a fourth frame corresponding to a stop point.

A method includes receiving input at a computing device, where the input indicates a value of a local encoding parameter, indicates a value of a remote encoding parameter, and identifies a first subset of streams and a second subset of streams. The first subset and the second subset correspond to renditions of a video stream. The method further includes sending, to a media server, the first subset and the value of the remote encoding parameter, where the first subset includes a particular rendition of the video stream generated using a lossless encoding scheme, and wherein the media server is configured to generate the second subset of streams based on the value of the remote encoding parameter and based on the particular rendition.

Distributed encoding of a video stream

A method includes receiving, at a media server from a computing device, a first request for a manifest associated with media content. The method also includes generating, at the media server, the manifest based on a manifest type and a content segmentation type. The manifest identifies one or more segments of one or more adaptive streaming renditions. The method further includes sending the manifest from the media server to the computing device. The method includes receiving a second request from the computing device, where the second request identifies a requested segment of an adaptive streaming rendition identified by the manifest. The method also includes sending the requested segment from the media server to the computing device in response to the second request.

Manifest generation and segment packetization

Systems and methods of configuring and performing distributed encoding of a video stream are disclosed. A method includes receiving a video stream at a computing device and receiving input indicating a value of a local encoding parameter and a value of a remote encoding parameter. The method further includes encoding the video stream at the computing device based on the value of the local encoding parameter to generate a first encoded stream. The method includes sending the first encoded stream and the value of the remote encoding parameter to a media server. The media server is configured to generate a second encoded stream based on the value of the remote encoding parameter and the first encoded stream.

A particular method includes receiving, at a media server, a request for a first rendition of a stream. The method also includes generating a portion of the first rendition. Generating the portion of the first rendition includes determining whether one or more first overlay images are enabled and inserting the one or more first overlay images into one or more frames of the portion of the first rendition conditioned on the one or more first overlay images being enabled. The method further includes sending the portion of the first rendition to a computing device.

Insertion of graphic overlays into a stream

A method includes receiving a request at a media server from a computing device for a portion of a particular rendition of content that is available for adaptive streaming. The request received while the media server has access to a single rendition of the content. When the portion is part of the single rendition, the media server sends the portion retrieved from the single rendition to the computing device in response to the request. When the portion is not part of the single rendition, the media server generates the portion by transcoding a corresponding portion of the single rendition of the content, stores the generated portion in a cache of the media server, and sends the generated portion to the computing device in response to the request. The method further includes removing portions of one or more outdated renditions from the cache while maintaining the generated portion in the cache.
