Common DMA GStreamr allocator

[Bing Song]

No, i.MX8 will use DMA FD to share video frame buffer. No physical address any more.

Are you talking about a DMA allocator that exports physical addresses to userspace?

Hi,



Currently 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?
