DAER ALL:
I have a project which requires dual display support (hdmi + VGA), both of the displays should show the different content.
but now ,it can show the same content. i want to test play vedio on one dispaly. SO i use external\linux-test\test\mxc_vpu_test to build a applcation,
but it can not work.
