7701844813 plugin: bufferpool: Delete ACQUIRE_FLAG_NO_ALLOC flag.
Delete the GST_VAAPI_VIDEO_BUFFER_POOL_ACQUIRE_FLAG_NO_ALLOC flag.
In fact, no one is using that flag, and all vaapi buffers should
have GstVaapiVideoMeta.

bcc480b70e vaapibufferpool: add gst_vaapi_video_buffer_pool_copy_buffer()
This function will inform the element if it shall copy the generated
buffer by the pool to a system allocated buffer before pushing it
to downstream.

9132510ce0 vaapivideobufferpool: add GstVaapiVideoBufferPoolAcquireParams
Useful to let the pool know the current surface proxy when calling
gst_buffer_pool_alloc_buffer() / gst_buffer_pool_acquire_buffer()

6c5b6232da vaapivideobufferpool: share options flag with pluginbase
Originally, vaapivideobufferpool has a set of boolean variables for the
buffer configuration options.

This pach changes these boolean variables for a single bitwise, just as
it is used in pluginbase. Hence, the internal enum was moved to
vaapivideobufferpool header.

50b2423a2b pluginbase negotiates allocator with bufferpool
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.

9f46a94d2a vaapivideobufferpool: remove GL_TEXTURE_UPLOAD_META
Since gstreamer-vaapi is coupled with gstreamer releases, there is no need to
keep compatibility definition.

This patch removes the definition of
GST_BUFFER_POOL_OPTION_VIDEO_GL_TEXTURE_UPLOAD_META since it is in
gst-plugins-base version 1.2.2

82fc406dfd plugins: add support for dma_buf exports (v4l2src).
Allow v4l2src element to connected to vaapipostproc or vaapisink when
"io-mode" is set to "dmabuf-import". In practice, this is a more likely
operational mode with uvcvideo. Supporting v4lsrc with "io-mode" set
to "dmabuf" could work, but with more demanding driver or kernel reqs.

Note: with GStreamer 1.4, v4l2src (gst-plugins-good) needs to be built
with --without-libv4l2.

1ef5a3a200 plugins: allow bufferpool to not allocate vaapi video meta.
Add GST_VAAPI_VIDEO_BUFFER_POOL_ACQUIRE_FLAG_NO_ALLOC params flag that
can be used to disable early allocations of vaapi video metas on buffers,
thus delagating that to the bufferpool user.

6b6c10d94d plugins: request GLTextureUpload meta on buffers in the buffer pool.
Requesting the GLTextureUpload meta on buffers in the bufferpool
prevents such metas from being de-allocated when buffers are released
in the sink.

This is particulary useful in terms of performance when using the
GLTextureUploadMeta API since the GstVaapiTexture associated with
the target texture is stored in the meta.

15519ebe3d legal: add per-file authorship information.
Credit original authors on a per-file basis as we cannot expect people
to know all country-specific rules, or bother browsing through the git
history.

55b3053b88 plugins: mark a few more functions as internal.
Mark the following functions are internal, i.e. private to the vaapi plug-in:
- gst_vaapi_video_buffer_pool_get_type()
- gst_vaapi_video_converter_glx_get_type()
- gst_vaapi_video_converter_glx_new()

5b11b83321 plugins: add GstVaapiVideoMemory and GstVaapiVideoBufferPool objects.
Add initial support for GstVaapiVideoMemory backed buffer pool. The memory
object currently holds a reference to GstVaapiVideoMeta.
