A method that includes determining input-resolution parameters for an input resolution, receiving first and second output resolutions from an electronic device, wherein the first output resolution includes first output-resolution parameters and the second output resolution includes second output-resolution parameters, calculating a first value by using the input-resolution parameters and the first output-resolution parameters, calculating a second value by using the input-resolution parameters and the second output-resolution parameters, selecting one of the first and second output resolutions based on a comparison between the first and second values, providing the selected output resolution to the electronic device, and receiving a video stream from the electronic device, wherein the video stream has a resolution corresponding to the selected output resolution.

Comparison-based selection of video resolutions in a video call

Systems and methods are provided to automatically discover if an email address contact is video chat capable. A server receives a request from an electronic device to determine video chat capability associated with an email address. It compares the email address with a listing of email addresses, wherein the listing includes email addresses associated with other electronic devices having video chat capability. If an entry in the listing matches the email address, it returns a message configured to automatically enable addition of the email address as a video chat contact on the electronic device.
