Changed logs:
1. support corridor mode. Resolution changes to 2304x1280 at 3M
2. In corridor mode, the main stream supports no graphics of the secondary stream when the resolution is 2304x1280.And when the resolution is 1920*1080, it supports main and secondary steam. And the device is not enough memory, and the resolution is 2304x1280, there may be no picture.So we suggest that we only support 1920 * 1080
3. The corridor mode does not support the human detection
