V4L2 element can import and export DMA FD memory.
glimagesink/kmssink can import DMA memory. Is there common
DMA GStreamer allocator? So we can use the common DMA
allocator if driver can't export DMA FD. As I know, ion
driver (Android develop it) which in Linux Kernel stage fold
can allocate DMA memory. Do GStreamer can accept common DMA
GStreamer allocator based on ion driver?<o:p></o:p></span></p>
