TDA2HG: [OpenGL RGB ] What's the effect way to exchange the RGB data

Hello,

You can use YUV texture and render to RGB output. Are you facing any problems with rendering to RGB?

yes， it's ok to do that, but later we need to render the YUV and RGB together as the camera input is YUV, that sound impossible.

so we expect the convert the camera yuv to rgb by ourself, and then render all textures with RGB.

in yuv we can use dmafd to exchange the data between CPU and GPU, and how about the RGB data?

Hi Hemant:

  Thanks!

  when OpengGL do converting  the YUV to RGB, in glbind?  or in shader program?

Thread is unlocked now.

hi Karthik:

thanks for unlocking.

but i still don't understand how is the fbo usage;

how can i create fbo and write NV12 format texture into the fbo?

would you reply it?

thanks.

You can create an RGB fbo and use OpenGL ES to read YUV as an external texture. This will convert YUV to RGB. You will have to create an eglmage with EGL_LINUX_DMA_BUF_EXT and provide dmabuf parameters for NV12 Y/UV planes.

I have a question about create RGB fbo:

create an RGB fbo: I still need to create an eglmage with EGL_LINUX_DMA_BUF_EXT and provide dmabuf parameters for RGB planes, is right?

And i do like that.

But the eglCreateImageKHR returned EGL_BAD_MATCH when I set EGL_LINUX_DRM_FOURCC_EXT attribute as FOURCC_STR("AR24");

Is the TDA2 don't support "AR24"? or RGB format use other FOURCC_STR?

my sdk version is 3.06.

if don't support ,do you have any other method?

thanks

thanks for replying, i have already resolved it about three or four month ago.
