如何用openGL做解码后处理

Answer 1

代码示例

// 1.创建NativeImage 
InitEglContext(); 
GLuint textureId; 
glGenTextures(1, &textureId); 
OH_NativeImage* nativeImage = OH_NativeImage_Create(textureId, GL_TEXTURE_2D); 
OHNativeWindow* inputWindow = OH_NativeImage_AcquireNativeWindow(image); 
// 2.设置NativeWindow给解码器 
OH_VideoDecoder_SetSurface(OHNaitveWindow* inputWindow);
