How to use glTexDirectVIVMap in Qt APP?

kenjigan — Tue, 20 Nov 2018 08:28:54 GMT

My board is I.Mx6Q sabread. Find this document that introduce a tool that can handle fullHD (1080p) at 60FPS

My goal is to use glTexDirectVIVMap function in QT app like this:
...
glBindTexture (GL_TEXTURE_2D, textures[0]);
/* Physical and Virtual addresses */
glTexDirectVIVMap(GL_TEXTURE_2D, width, height, GL_VIV_NV12,
&buffers[buf.index].start, &(buffers[buf.index].offset));
glTexDirectInvalidateVIV(GL_TEXTURE_2D);
...

What I have already done:
build meta-freescale and it succeeded http://freescale.github.io/#download
PATH=${PATH}:~/bin
mkdir fsl-community-bsp
cd fsl-community-bsp
repo init -u https://github.com/Freescale/fsl-community-bsp-platform -b rocko
repo sync
Use these command to start QtCreator
cd /home/fsl-release-bsp/build/tmp/deploy/sdk/
source /opt/fsl-imx-fb/3.14.52-1.1.1/environment-setup-cortexa9hf-vfp-neon-poky-linux-gnueabi
cd /opt/Qt5.7.0/Tools/QtCreator/
bin/qtcreator
Add these in .pro (using qmake)

How to fix these error? Or what did I do wrong?

Hi Kenji

one can try with nxp official bsps from Code Aurora git repositories repository,

for example please check i.MX_Graphics_User's_Guide.pdf, i.MX_Yocto_Project_User's_Guide.pdf

included in linux documentation:

https://www.nxp.com/webapp/Download?colCode=L4.9.88_2.0.0_LINUX_DOCS&Parent_nodeId=1337699481071706174845&Parent_pageTyp…
