* You can specify initialized subsystem by flags which is * bitwise OR of the following constants: * * * SDL2::INIT_TIMER - timer subsystem * * SDL2::INIT_AUDIO - audio subsystem * * SDL2::INIT_VIDEO - video subsystem * * SDL2::INIT_JOYSTICK - joystick subsystem ...

在SDL2库的AudioSubSystem中,如何处理音频输入和输出? Android 部分源码分析 Android部分的初始化和视频部分基本相同。 这里简单看一下。 在SDLActivity中调用了 SDL.setupJNI()。 SDL.setupJNI()中SDLAudioManager.nativeSetupJNI()开始对JNI方法进行初始化。 在SDL_android.c中,nativeSetupJNI初始化JNI回调java方法的...
