In my open gl es app i am use zero-copy technology (passing vpu buffer pointer to glvivdirecttexture) .How I am may get access to this vpu buffer from another process? In Freescale driver exist this API?
Thank you
Hi Ruslan
You should use ExtBufCfg struct from the VPU API that is used when the host application wants to give external memory configuration to VPU. Stream data and some output picture data are directly accessed by the host processor and VPU. For a more comprehensive way of controlling the VPU, a set of API functions is provided that includes all of the required operations from the host processor side
Please check the VPU API document installed in your documentation folder of your Linux BSP.
