Originally vaapivideobufferpool instantiates its own allocator regardless the
received configuration, and it relies in custom configuration options to
choose which kind of allocator instantiate.
This patch transfers the responsibility of the allocator instantiate to
vaapipluginbase and pass it to the vaapivideobufferpool through its
configuration.
* gst/vaapi/gstvaapipluginbase.c
+ set_dmabuf_allocator(): inserts a dmabuf allocator in the bufferpool
+ ensure_sinkpad_buffer_pool(): set a normal vaapi video allocator in
bufferpool configuration
+ gst_vaapi_plugin_base_propose_allocation(): call set_dmabuf_allocator() if
needed.
+ gst_vaapi_plugin_base_decide_allocation(): set a normal vaapi video
allocator in bufferpool configuration
* gst/vaapi/gstvaapivideobufferpool.c
+ gst_vaapi_video_buffer_pool_set_config(): instead of instantiate the
allocator, process the received one through its configuration.
* gst/vaapi/gstvaapivideobufferpool.h: removed
GST_BUFFER_POOL_OPTION_DMABUF_MEMORY since it is not used anymore.
* gst/vaapi/gstvaapivideomemory.c
+ gst_vaapi_is_dmabuf_allocator(): new helper function to identify a dmabuf
allocator with the vaapi qdata.
