Abstract: The present technology pertains to a method to balance the performance of an application with the device health and the application runtime health statistics utilizing a hybrid approach. In the hybrid approach, the static performance control is a robust machine learning algorithm trained on data from many client devices and applications. The dynamic performance control is local to the client device and the application and reacts to the real-time device performance and application performance. Additionally, a user can provide their preferences for the performance and resource optimization of the application.

Abstract: In various embodiments, a device receives a first video stream of a video conference. The device receives a second video stream of the video conference. The second video stream includes an indicated location for video of the second video stream relative to video of the first video stream. The device merges the first video stream and the second video stream into an overlapped video having the video of the second video stream located at the indicated location relative to the video of the first video stream. The device provides the overlapped video for display.

Abstract: In one embodiment, a system for setting frame priority according to priority levels includes a video encoder to encode a first video frame of a live video stream yielding an encoded first video frame having a first priority level, and a processor to read, from a memory, an estimate of a time delay, the time delay being a time for data in the live video stream to be transferred from a first device to a second device, and determine if the estimate of the time delay exceeds a pre-defined delay, and wherein if the estimate of the time delay exceeds the pre-defined delay, the video encoder is operative to encode a second video frame with a higher priority level than the first priority level, the second video frame being a most recent video frame to be presented from the live video stream for encoding after the first video frame. Related apparatus and methods are also described.

Abstract: In one implementation, multiple parameter sets associated with different resolutions for a media stream are identified. A parameter set table including the plurality of parameter sets and associated resolutions is generated. After, establishing a communication session with an endpoint, the parameter set table is sent to the endpoint as part of the communication session. Also through the same communication session, video data of the media stream is sent to the endpoint.
