摘要： Some embodiments provide a method for allowing a first device that is in a video conference with a second mobile device to remotely control the second mobile device. The method sends images captured by a camera of the first device to the second device. The method receives images captured by a camera of the second device. The method sends a command through a communication channel of a real-time communication session to the second device. The command is for instructing the second device to perform an operation that modifies the images captured by the camera of the second device.

摘要： For a first device participating in a video communications session with a second device, some embodiments provide a method that receives sets of encoding features supported by each of one or more decoders of the second device. The method selects an encoder for the video communication session from several encoders available to the first device. The method selects a set of encoding features of the selected encoder based on the sets of encoding features received from the second device. The method transmits an encoded video bitstream to the second device along with information identifying the selected features in order for the second device to select a decoder to decode the bitstream.

摘要： Systems, methods, and a computer readable medium for performing auto exposure (AE) techniques that are beneficial in variable lighting conditions—and particularly applicable to handheld and/or mobile videoconferencing applications—are disclosed herein. Handheld and/or mobile videoconferencing applications—unlike their fixed camera counterparts—are often exposed to a wide variety of rapidly changing lighting and scene conditions, and thus face a difficult trade-off between adjusting exposure parameter values too frequently or not frequently enough. In personal electronic devices executing such handheld and/or mobile videoconferencing applications, it may be desirable to: use a small, centered, and center-weighted exposure metering region; set a relatively low brightness target value; and adjust the camera's exposure parameter values according to a distance-dependent convergence speed function. The use of such techniques, in conjunction with a relatively large stability region, may also improve the quality of a video encoder's temporal predictions—and thus video quality—in videoconferencing applications.
摘要翻译：本文公开了用于执行可变照明条件有利的自动曝光（AE）技术的系统，方法和计算机可读介质，并且特别适用于手持和/或移动视频会议应用。手持和/或移动视频会议应用程序（与固定摄像机对应的设备不同）通常会受到各种快速变化的照明和场景条件的影响，因此在过多调整曝光参数值或不够频繁地面临困难的折衷。在执行这种手持和/或移动视频会议应用的个人电子设备中，可能需要：使用小的，中心的和中心加权的曝光计量区域; 设定相对较低的亮度目标值; 并根据距离相关的收敛速度功能调整相机的曝光参数值。使用这样的技术结合相对较大的稳定性区域，也可以提高视频编码器在视频会议应用中的时间预测的质量，从而提高视频质量。
