| Abstract: | In order to shorten H.264 encoding time and improve encoding efficiency, an idea about translating Hi3716MV400 H.264 hardware encoder to Android Linphone come up. In this paper, the transplantation method of the hardware encoder is described in detail which includes building Linphone development environment, adding H.264 hardware encoding library, correcting H.264 hardware encoding function. Experimental tests show that the Linphone can communicate with another client normally in Hi3716MV400 STB, making the video communication occupies less cpu resources and crashes rarely. |
