Can glTexDirectVIVMap() be used in Android Studio project

srzhou — Wed, 21 Jun 2017 02:48:10 GMT

I have a problem of using glTexDirectMap() in my Android Studio project to reduce CPU load for a camera application, as I simply add gl2ext.h in the include directory, but I don't know how to use the corresponding libs(such as libEGL.so, libGLESv2.so, etc.).

My platform is i.MX 6Q and Linux version: 3.10.53

The question is: can the function be applied in an Android Studio project? And how?

Hi sr,

imxeglvivsink Automatically enabled whenever possible. If the input frame uses DMA memory, The

glTexDirectVIVMap function is used to instruct the GPU to read the pixels via DMA from the given memory region.

If you are not working with latest NXP BSP, GL_VIV_XXX viv textures was not defined in my GLES2/gl2.h / gl2ext.h since it comes from Android's NDK, however you can take it from:

chromium-imx/imx_gl_viv_direct_texture.h at master · Freescale/chromium-imx · GitHub
