Computing devices may implement instant video communication connections for video communications. Connection information for mobile computing devices may be maintained. A request to initiate an instant video communication may be received, and if authorized, the connection information for the particular recipient mobile computing device may be accessed. Video communication data may then be sent to the recipient mobile computing device according to the connection information so that the video communication data may be displayed at the recipient device as it is received. New connection information for different mobile computing devices may be added, or updates to existing connection information may also be performed. Connection information for some mobile computing devices may be removed.

Instant video communication connections

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.

Answering a call with client through a host

A video streaming method for transitioning between multiple sequences of coded video data may include receiving and decoding transmission units from a first sequence of coded video data. In response to a request to transition to a second sequence of coded video data, the method may determine whether a time to transition to the second sequence of coded video data can be reduced by transitioning to the second sequence of coded video data via an intermediate sequence of coded video data. If the time can be reduced, the method may include receiving at least one transmission unit from an intermediate sequence of coded video data that corresponds to the request to transition, decoding the transmission unit from the intermediate sequence, and transitioning from the first sequence to the second sequence via the decoded transmission unit from the intermediate sequence.

Computing devices may implement dynamic display of video communication data. Video communication data for a video communication may be received at a computing device where another application is currently displaying image data on an electronic display. A display location may be determined for the video communication data according to display attributes that are configured by the other application at runtime. Once determined, the video communication data may then be displayed in the determined location. In some embodiments, the video communication data may be integrated with other data displayed on the electronic display for the other application.

Dynamic display of video communication data

A system and method for conducting a video call between an originating device and a terminating device by establishing a peer-to-peer (P2P) connection between the devices. The originating and terminating devices exchange candidate information through a P2P server, except that the candidate information for the terminating device is altered before arriving at the originating device. The altering includes changing the IP address and corresponding port for each candidate. The originating device uses the altered candidate information to derive new candidate pairs that are sent to the terminating device, which uses the new candidate pairs to also derive a second candidate list. If the candidate pairs match, a P2P connection is established between the devices.

Establishing a connection for a video call

Computing devices may implement dynamic detection of pause and resume for video communications. Video communication data may be capture at a participant device in a video communication. The video communication data may be evaluated to detect a pause or resume event for the transmission of the video communication data. Various types of video, audio, and other sensor analysis may be used to detect when a pause event or a resume event may be triggered. For triggered pause events, at least some of the video communication data may no longer be transmitted as part of the video communication. For triggered resume events, a pause state may cease and all of the video communication data may be transmitted.

Dynamic detection of pause and resume for video communications

Computing devices may implement dynamic transitions from video messages to video communications. Video communication data for a video message may be received at a recipient device. The video communication data may be displayed as it is received, and recorded for subsequent playback. An indication of a selection to establish a video communication with the sender of the video message may be received, or an indication that display of the video communication is to be ceased may be received. If a video communication is to be established, then a video communication connection with the sender of the video message may be created so that subsequent video communication data may be sent via the established connection.

Dynamic transition from video messaging to video communication

A wireless device described herein can use information on data flow, in addition to indications from the physical network, to decide on suitable bandwidth usage for audio and video information. This data flow information is further used to determine an efficient network route to use for high-quality reception and transmission of audio and video data, as well as the appropriate time to switch between available network routes to improve bandwidth performance.

System and method for optimizing video conferencing in a wireless device

Some embodiments provide a method of combining multiple streams of data packets into a single combined stream in a manner that facilitates accurate estimation of bandwidth of a connection over a network between two devices. When combining the streams into the combined stream, the method associates a set of packets from a first stream and a reference packet from a second stream to form a longer sequence of packets in the combined stream. The method sends the combined stream from a first device to a second device so that the second device can estimate the bandwidth of the connection between the first and second devices based on the inter-arrival times of the packets in the sequence of packets.
