              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.
