Abstract:
1. A video communication method for dynamically modifying video encoding, the method comprising: obtaining, by a video receiver, a video window size change signal generated in the video receiver and indicating a changing of a video window size of a video being received by the video receiver; generating, by the video receiver, an encoding modification signal according to the change signal, the encoding modification signal indicating that at least one of an encoding rate, a bit rate, a resolution and a frame rate of an encoder of a video sender sending the video that is being received by the video receiver, needs to be modified; transmitting, by the video receiver, the encoding modification signal to the video sender in a same channel in which the video sender sends the video that is being received by the video receiver; receiving, by the video sender, the encoding modification signal; and modifying, by the video sender, said at least one of the encoding rate, the bit rate, the resolution and the frame rate of the encoder according to the encoding modification signal received by the video sender.
