Abstract: Devices, methods, and non-transitory program storage devices are disclosed to enable the automatic establishment of a secure audio/video data streaming connection between electronic devices. For example, a first electronic device may enter into a first state of a peer device advertising protocol, and then, based on a determination that the first electronic device meets a first set of device state criteria (e.g., including at least an orientation state criterion), the first electronic device may enter into a second (e.g., enhanced) state of the peer device advertising protocol. In response to detecting a presence of a second electronic device in its proximity, the first electronic device may connect to the second electronic device via a secure peer-to-peer connection protocol and then send one or more images captured by a first image capture device of the first electronic device to the connected second electronic device via the secure wireless peer-to-peer connection protocol.

Abstract: A method and apparatus of a device that manages a video stream is described. In an exemplary embodiment, the device receives a plurality of packets for a video stream from a transmitting device via a server. The device may additionally store a first packet of the plurality of packets in a first buffer when the first packet is on-time and store a second packet of the plurality of packets in a second buffer when the second packet is late. The device may also further forward a frame from the second buffer to the first buffer when frame is complete.

Abstract: The embodiments described herein can dynamically adjust timing of network bandwidth estimations by adjusting a target frequency for sending probing sequences to one or more receivers of content. The receivers receive these probing sequences from a transmitter and respond to the transmitter with network bandwidth estimations. In one embodiment, the probing sequences can use the content itself to create the probing sequences. The embodiments can be used in video conferencing applications to control how a transmitter of content can adjust transmissions based upon the network bandwidth estimations. In one embodiment, a policy can be used at a transmitter to begin a video transmission with a high frequency target for sending probing sequences (with, e.g., smaller length probing sequences) and transition to a lower frequency target (with, e.g., longer length probing sequences) when network bandwidth deteriorates and then return to the higher frequency target when the network bandwidth improves.

Abstract: A computer system outputs audio content via one or more audio output devices. If the audio content includes information that enables spatialization of the audio content, the system outputs the audio content in a simulated three-dimensional environment, including, if the audio content corresponds to a first category of content, causing the one or more audio output devices to simulate production of the audio content in a first virtual space, and if the audio content corresponds to a second category of content, causing the one or more audio output devices to simulate production of the audio content in a second virtual space that has different simulated acoustic properties than simulated acoustic properties of the first virtual space.

Abstract: Techniques presented herein provide an improved relay user experience and improved management of scarce computing and network resources as the number of relay endpoints increases. A sourcing endpoint device may generate a media feed, such as video and/or audio feed, representing contribution from a conference participant. The sourcing endpoint device may generate a priority value for the media feed, and the priority value may be transmitted to other members of the relay along with the input feed. Priority values of the different relay participants may be used by other devices, for example, intermediate servers or receiving endpoint devices, to manage aspects of the relay. For example, a relay server may prune streams from select endpoint devices based on relative priority values received from those devices. Alternatively, receiving endpoint devices may alter presentation of received feeds based on their associated priority values.

Abstract: Techniques are disclosed relating to multiway communications. In some embodiments, a first electronic device initiates a multiway call between a plurality of electronic devices and exchanges a first secret with a first set of electronic devices participating during a first portion of the multiway call, the first secret being used to encrypt traffic between the first set of electronic devices. The first electronic device receives an indication that first set of participating electronic devices has changed and, in response to the indication, exchanges a second secret with a second set of electronic devices participating during a second portion of the multiway call, the second secret being used to encrypt traffic between the second set of participating electronic devices. In some embodiments, the indication identifies a second electronic device as leaving the multiway call, and the second secret is not exchanged with the second electronic device.

Abstract: The subject technology provides a video conferencing application in which a live incoming or outgoing video stream can be supplemented with supplemental content, such as stickers, animations, etc., from within the video conferencing application. In this manner, a user participating in a video conferencing session with a remote user can add stickers, animations, and/or adaptive content to an outgoing video stream being captured by the device of the user, or to an incoming video stream from the device of the remote user, without having to locally cache/store a video clip before editing, and without having to leave the video conferencing session (or the video conferencing application) to access a video editing application.

Abstract: Aspects of the subject technology provide for transcription of audio content during a conferencing session, such as an audio conferencing session or a video conferencing session. The transcription can be generated by the device at which the audio input is received, and transmitted to a remote device at which the transcription is displayed. Video content can also be provided from the device that generates the transcription to the remote device that displays in the transcription. The transcription can be provided with time information corresponding to time information in the video content, for synchronized display of the transcription and the corresponding video content.

Abstract: A device implementing dynamic redundancy may include at least one processor configured to receive, from another device, packet reception data corresponding to video data previously provided for transmission from the device to the other device and determine, based at least in part on the packet reception data, an amount of redundancy to apply to video data provided for transmission to the other device. The at least one processor may be further configured to determine, based at least in part on the amount of redundancy, an encoding scheme for applying the redundancy to the video data. The at least one processor may be further configured to apply the amount of redundancy to the video data based at least in part on the encoding scheme to generate redundant data items and provide the video data and the redundant data items for transmission to the other device.
