Linux/DRA746: How to bind TI drm buffer to OpenGL Texture?

Tool/software: Linux

I want to render video frame (decoded from libdce) as texture (in webengine).

Is there example code to demonstrate how to use it?

I know there is:

eglCreateImageKHR(eglDisplay, eglContext, EGL_DRM_BUFFER_MESA,(EGLClientBuffer)(intptr_t)drmName, attribs);

EGLint attribs[] = {
EGL_WIDTH, width,
EGL_HEIGHT, height,
EGL_DRM_BUFFER_STRIDE_MESA, pitch/4,
EGL_DRM_BUFFER_FORMAT_MESA,
EGL_DRM_BUFFER_FORMAT_ARGB32_MESA,
EGL_DRM_BUFFER_USE_MESA,
EGL_DRM_BUFFER_USE_SHARE_MESA,
EGL_NONE
};

glEGLImageTargetTexture2DOES(EGLenum target, EGLImageKHR image)

-- does TI gfx driver runs similar?

-- does TI gfx driver create EGLImage from NV12 buffer directly?

Hi Halley,

I have forwarded your question to graphics experts.

Can you just tell which version is your SDK?

Hi Halley,
Refer create_texture function here git.ti.com/.../display-kmscube.c
You can use filevpedisplay with --kmscube option to demonstrate this.

Refer commit id
f221e462afd8461517b1dd9d8ef04b67a07275fa of omapdrmtest.

Thanks

Hi Halley,
You can use viddec3test with --kmscube option also
