TDA4VM: Usually glViewPort zero point set to left bottom, did tda4 set to left top? how can I change it to left bottom?

Hello,

glClipControlEXT(GL_UPPER_LEFT_EXT, GL_NEGATIVE_ONE_TO_ONE_EXT); Modify to glclipcontrolext (gl_lower_left_ext, gl_new_one_to_one_ext);

The image shows the Y direction is reversed

Hello,

The macros used by glClipControlEXT are defined in vision_apps/kernels/srv/gpu/3dsrv/Include/GLES2/gl2ext.h targetfs/usr/include/GLES2/gl2ext.h. If you want to change the origin from upper left to bottom left, could you try modifying GL_UPPER_LEFT_EXT to GL_LOWER_LEFT_EXT?
