GPU (vcsm) -> input_port (isp component).
I use the EGL_IMAGE_BRCM_VCSM when generating a buffer that I eventually turn into an opengl texture that is attached to a frame buffer object (fbo) in opengl. I render into this fbo which renders into the vcsm buffer.
After a frame rendered with the gpu has been completed is it possible to use the vcsm_info.handle to set the MMAL_BUFFER_HEADER_T::data parameter and send this buffer off to the isp component input port?
I use this particular instance of the isp component to do a color conversion from rgba to I420 (yuv).
Some insight into this would be appreciated!
