A block-request streaming system provides for low-latency streaming of a media presentation. A plurality of media segments are generated according to an encoding protocol. Each media segment includes a random access point. A plurality of media fragments are encoded according to the same protocol. The media segments are aggregated from a plurality of media fragments.

Embodiments of mechanisms for dynamic media content type streaming management for mobile devices are generally described herein. In some embodiments, the mobile device may receive selection input pertaining to generating output from a media file containing at least two of audio data, video data, and closed-captioning data, the selection input selecting at least one of audio, video, and closed-captioning to be output during play of the media content. In some embodiments, the mobile device may generate an audio output as a signal in response to the selection input including audio. In some embodiments, the mobile device may generate a video output as a signal in response to the selection input including video. In some embodiments, the mobile device may generate a closed-captioning output as a signal in response to selection input including closed-captioning.

Technologies for casting digital media content include a source computing device communicatively coupled to a destination computing device. The source computing device is configured to transmit a set of identifiers of the source computing device to the destination computing device and receive a set of identifiers of the destination computing device from the destination computing device. Each set of identifiers includes a version (e.g., hardware or software) associated with the respective computing device and a unique identifier of the respective computing device. The source computing device is additionally configured to determine a subset of casting session parameters from a set of casting session parameters based on the one or more capabilities of the destination computing device which are usable by the destination computing device to establish a casting session and stream digital media content in accordance with the subset of casting session parameters. Other embodiments are described and claimed.

Technologies for streaming device role reversal include a source computing device and a destination computing device coupled via a communication channel. The source computing device and destination computing device are each configured to support role reversal. In other words, the source computing device and the destination computing device are each capable of switching between receiving and transmitting digital media content over the established communication channel. The source computing device is configured to initiate the role reversal, pause transmit functionality of the source computing device, and enable receive functionality of the source computing device. The destination computing device is configured to receive a role reversal indication from the source computing device, locally process the content, transmit a content stream to the source computing device, and display the content stream on an output device of the source computing device. Other embodiments are described and claimed herein.

Systems, methods, and computer-readable media are provided for producing and mixing a video stream based on a predetermined video layout template and a set of selectable video streaming parameters. A plurality of individual video streams is received from a respective plurality of participant users and mixed into a mixed video stream on a mixing server which is distributed to a plurality of viewing users. An authoring server allows an authoring user to configure various video streaming parameters which instruct the mixing and display of the mixed video stream.

Systems, methods, and non-transitory computer-readable media can be configured to determine a request for a video from a client device, wherein the video is associated with a plurality of reframed versions of the video. A reframed version of the video to provide in response to the request can be determined based at least in part on a consumption surface associated with the client device. The reframed version of the video can be provided to the client device for display.

The disclosed computer-implemented method may include (1) receiving a media stream, (2) determining a first priority level for the media stream, (3) generating one or more first encoded segments from a first segment of the media stream based on the first priority level, (4) determining, while generating the one or more first encoded segments, a second priority level for the media stream, the second priority level being different than the first priority level, (5) generating one or more second encoded segments from a second segment of the media stream based on the second priority level, and (6) streaming the one or more first encoded segments and the one or more second encoded segments to one or more client devices. Various other methods, systems, and computer-readable media are also disclosed.

Example implementations include a method for video processing, comprising performing a conversion between a current video unit of a video and a bitstream of the video according to a rule, wherein the rule specifies performing the conversion based on a predefined bitstream.
