코덱 기반 화면 녹화기의 시스템 사용 분석

Abstract

The range of screen recorder software's applications has been gradually increasing. The reason is that multimedia contents' utilization is growing very fast recently. In general, these screen recording software concurrently execute with other computer software and usually increase the burden of computer system resources. Therefore In this paper, we look into the computer resource usage of CPU and memory. We make a new experiment software for screen recording to obtain stable results. The software is consisted of screen capturing module and converter based on video codecs. The screen capture is performed periodically at an interval of a predefined time in our experimental software. We use Xvid as codec used in our screen recording software. Xvid is widely known as an useful open source video code. In experiment results, we make sure that the CPU shows constantly usage below 1% and memory usage indicates average below 410 MB. The software is not required a large amount of CPU computing resource. Therefore, we recommend that the screen recording software's utilization is desirable on the computers with sufficient resource. It is faced with an unexpected difficulty in small main memory.
