A Solution to Improving the Performance of VVOIP Based on C-Native Android OS

VVOIP is an extended application from VOIP, and just because of the video function VVOIP is more complicated than VOIP, for video processing, video capturing, video codec and video transmission need more CPU processing power and net bandwidth. In this paper, a hardware codec solution is proposed to improve the performance of the VVOIP application based on Android OS. Video hardware codec can help decrease the load of mobile devices CPU, leaving users enjoying more applications at the same time. The hardware-codec VVOIPs performance of VGA-size is 15%-20% better than the unimproved one through the test result.
