Abstract: A video playback buffer adjustment system is disclosed. The video playback buffer has a target size, measured in units of time of content, and includes a compressed frames queue and an uncompressed frames queue. The uncompressed frames queue has a minimum threshold queue size. If the size of the uncompressed frames queue falls below the minimum threshold size, then a next encoded frame in the compressed frames queue is removed from the compressed frames queue, decoded, and enqueued in the uncompressed frames queue. If a current size of the playback queue exceeds the target size plus Δ (a hysteresis value), then a playback frame rate is increased, and a presentation time of one or more frames in the uncompressed frames queue is adjusted according to the increased playback frame rate. If the playback queue size is less than the target size minus Δ, the playback speed can be reduced.

Abstract: The subject technology provides a messaging application in which an image can be captured and supplemented with supplemental content such as stickers, animations, etc., from within an active messaging thread. In this manner, a user participating in a messaging conversation with a remote user can add stickers, animations, and/or adaptive content to an image captured by the user, without having to locally cache/store the captured image before editing and without having to leave the messaging conversion (or the messaging application) to access an image editing application.

Abstract: Techniques are presented for managing for visual prominence of participants in a video conference, including conferences where participants communicate visually, such as with sign language. According to these techniques, a visual prominence indication of a participant in a video conference may be estimated, a video stream of the participant may be encoded, and the encoded video stream may be transmitted along with an indication of the estimated visual prominence to a receiving device in the video conference.

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: Techniques disclosed herein permit a party to identify a first (low-resolution) image as it is displayed on their, for example, smart phone during a video conference call. Identifying information specific to the first image may be collected and a request for a high-resolution copy of the image sent to the party sourcing the transmitted image. The high-resolution image may be sent from the image's sourcing device to the requestor's device during, or after, the video conference call. In some embodiments, the high-resolution image may be sent through an alternate communication channel (e.g., via a chat, social media or email channel). In other embodiments, the high-resolution image may be sent to a network-based service from which the requestor may obtain the image. In one embodiment, the sourcing device may message the requesting device that the image has been sent to the network-based service.

Abstract: A client device may be used to initiate or answer calls using a host device connected to a network. For example, when a phone operating as a host device receives an incoming call from a network, the phone may communicate the presence of the incoming call to one or more client devices such as laptop, desktop, tablet, or wearable devices that are associated with the host device. When an answer call selection is made at a client, a call answered communication may be sent from the client device to the host device. The host device may then communicate with the network to connect the call to the host, and when the call is connected, the host may hand-off the call to the client that sent the call answered communication.

Abstract: A method performed a local device that is communicatively coupled with several remote devices, the method includes: receiving, from each remote device with which the local device is engaged in a communication session, an input audio stream; receiving, for each remote device, a set parameters; determining, for each input audio stream, whether the input audio stream is to be 1) rendered individually or 2) rendered as a mix of input audio streams based on the set of parameters; for each input audio stream that is determined to be rendered individually, spatially rendering the input audio stream as an individual virtual sound source that contains only that input audio stream; and for input audio streams that are determined to be rendered as the mix of input audio streams, spatially rendering the mix of input audio streams as a single virtual sound source that contains the mix of input audio streams.

Abstract: The subject technology receives, at a local device, a requested camera format based on specifications of a display associated with a remote device. The remote device and the local device are devices participating in a video conference. The requested camera format includes a first resolution. Camera formats supported by a camera associated with the local device are determined. If a second resolution of a first camera format matches among the supported camera formats matches with the first resolution, the first camera format is selected for capturing the video stream by the camera. Otherwise, a second camera format among the supported camera formats is determined for capturing the video stream so as to maximize a field of view of the video stream relative to other camera formats supported by the camera.

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.

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.
