Abstract: The techniques disclosed herein improve user engagement and more efficient use of computing resources by providing dynamically controlled view states for communication sessions based on a number of people depicted in shared video streams. In some configurations, a system can control the size and position of a video rendering based on the number of individuals depicted in a video stream. In some configurations, a stream depicting a threshold number of people can be rendered in the primary display area and other streams can be rendered in a secondary section. The primary area can be sized to scale a video depicting multiple people video to equalize the size of the people with renderings of single-person video streams. This helps a system provide a more granular level of control to equalize the representation of each person displayed within different video streams.

Abstract: The disclosed techniques improve user engagement and more efficient use of computing resources by providing dynamically controlled aspect ratios for communication session renderings based on a number of people depicted in shared video streams. A system can identify select streams depicting at least a threshold number of individuals. A first aspect ratio can be selected from a number of preset aspect ratios for the display of select streams depicting at least the threshold number of individuals. A second aspect ratio can be selected for the display of other individual streams having video components depicting less than the threshold number of individuals. In some embodiments, the first aspect ratio is greater than the second aspect ratio. By switching between aspect ratios depending on a number of individuals depicted in each video stream, a system can improve user engagement by equalizing the display each person participating in a communication session.

Abstract: The disclosed techniques improve user engagement and promote efficient use of computing resources by providing dynamically controlled aspect ratios for communication session renderings based on a physical orientation of a device. In some configurations, a system can select a first aspect ratio for individual video streams of a communication session when a device is in a first orientation, e.g., a portrait orientation. In addition, the system can select a second aspect ratio for the individual video streams when the device is in a second orientation, e.g., a landscape orientation. In some configurations, the first aspect ratio can be greater than the second aspect ratio, or the aspect ratios can be selected based on a target aspect ratio, which can be adjusted over time. By dynamically selecting an aspect ratio for individual stream renderings, screen space of a device can be optimized while the device is held in various physical orientations.

Abstract: Techniques for conducting a communication session include obtaining capabilities of a set of one or more first devices and a second device configured to provide content to the first devices, the second device being configured to generate a plurality of data streams associated with the communication session; sending a first signal over a network to the second device to configure one or more operating parameters of the second device to generate the one or more data streams according to the capabilities of the first devices; and dynamically updating the operating parameters of the second device to alter the one or more data streams generated by the second device responsive to receiving an indication of changes in the capabilities of one or more of the first devices, a set of one or more third devices joining the communication session having different capabilities than the first set of devices, or both.
