Abstract:

Android visual communication applications typically use the View class to display decoded video images. In order to involve the severe memory consumption and output delay problems which always encounter in the commonly used image stretching method for decoding real-time video image, we analyze the reason, and give out two other methods to achieve the real-time magnified image display based on Android API(Application Programming Interface) or JNI(Java Native Interface). According to the experiment results, the research of source code is processed and a progressed method is achieved.

Key words: Android video application, image magnification, real-time display, efficiency analysis, research of source code
