Abstract: Performing a real-time application on a mobile device, involving communication of audio/video packets with a remote device. The mobile device may initially communicate the audio/video packets on a first communication channel with the remote device. During the real-time communication, the mobile device may determine if no packets have been received by the mobile device from the remote device for a first threshold period of time. If no packets have been received by the mobile device from the remote device for the first threshold period of time, the mobile device may establish a second communication channel for transmission of the audio/video packets with the remote device. In response to using the second communication channel, the mobile device may modify a resolution or bit rate of the audio/video packets transmitted to the remote device.

Abstract: Conducting a real time application between a mobile device and a remote device. A first one or more messages may be transmitted to the remote device to establish a primary channel of communication for the real-time application. The primary channel may use a first radio access technology (RAT), such as WiFi or a cellular RAT. A second one or more messages may be transmitted to the remote device to establish a secondary channel of communication for the real-time application. The secondary channel may use a second RAT that is different from the first RAT. Data of the real-time application may be transmitted over both the primary channel and the secondary channel in a concurrent or redundant fashion.

Abstract: A method for detecting and recovering from a transmission channel change during a streaming media session is disclosed. The method can include a wireless communication device detecting a stall condition resulting from a transmission channel change. The method can further include the wireless communication device capturing a snapshot of a current transmission parameter state of the streaming media session in response to detecting the stall condition. The method can also include the wireless communication device using the snapshot to restore the streaming media session to the transmission parameter state captured by the snapshot following completion of the transmission channel change.

Abstract: 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 my 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.

Abstract: 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.

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: Establishing a communication channel via a relay server with reduced setup time. Upon request by an initiating communication device a relay allocation server may allocate a single relay server for use in a communication session between the initiating communication device and one or more recipient communication devices. The relay server may be selected to perform favorably for the initiating communication device. Messaging for establishment of the communication session may be performed using persistent messaging connections, to avoid connection establishment cost. Messaging may also be performed using address tokens to avoid the cost of discovering global IP addresses. Following establishment of the communication session, the relay server may discover the IP address of one or more recipient communication devices, and may initiate reallocation of those devices to another relay server.

Abstract: 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.
