Fix GstVaapiVideoBufferPool::reset_buffer() to reset the underlying
memory resources, and more particularly the VA surface proxy. Most
importantly, the GstVaapiVideoMeta is retained. Cached surface in
memory are released, thus triggering a new allocation the next time
we need to map the buffer.
Make sure GstVaapiVideoMemory allocates VA surface proxies from a
pool stored in the parent VA memory allocator.
This fixes the following scenario:
- VA video buffer 1 is allocated from a buffer pool
- Another video buffer is created, and inherits info from buffer 1
- Buffer 1 is released, thus pushing it back to the buffer pool
- New buffer alloc request comes it, this yields buffer 1 back
- At this stage, buffers 1 and 2 still share the same underlying VA
surface, but buffer 2 was already submitted downstream for further
processing, thus conflicting with additional processing we were
about to perform on buffer 1.
Maybe the core GstBufferPool implementation should have been fixed
instead to actually make sure that the returned GstBuffer memory we
found from the pool is writable?
Always make sure to allocate a VA surface proxy for GstVaapiUploader
allocated buffers, i.e. make gst_vaapi_uploader_get_buffer() allocate
a proxy surface.
This fixes cases where we want to retain the underlying surface longer,
instead of releasing it back to the surface pool right away.
Add gst_caps_set_interlaced() helper function that would reset the
interlace-mode field to "progressive" for GStreamer >= 1.0, or the
interlaced field to "false" for GStreamer 0.10.
Fix gst_vaapi_video_context_prepare() to also query upstream elements
for a valid GstContext. Improve comments regarding the steps used to
lookup or build that context, thus conforming to the GstContext API
recommendations.

Fix _getcaps() implementation to not report codecs with size information
filled in the returned caps. That's totally useless nowadays. Ideally,

which is able to parse the elementary bitstreams itself.

Install a new video converter that supports X11 pixmap targets for X11

After the code got moved to create the gst_vaapi_create_display() helper,
this comparison was not updated to dereference the newly-created
pointer, so the code was comparing the pointer itself to the type, and
therefore failing to retrieve the VA display.

Fix new internal video format API, based on GstVideoFormat, to not
clobber with system symbols. So replace the gst_video_format_* prefix
with gst_vaapi_video_format_ prefix, even if the format type remains
GstVideoFormat.
Simplify gst_vaapi_create_display() helper as gst_vaapi_display_XXX_new()
performs the necessary validation checks for the underlying VA display
prior to returning to the caller. So, if an error occurred, then NULL is
really returned in that case.
If the video buffer pool config doesn't have new caps, then it's not
necessary to reinstantiate the allocator. That could be a costly
operation as we could do some extra heavy checking in there.
Fix reference counting issue whereby gst_memory_init() does not hold
an extra reference to the GstAllocator. So, there could be situations
where the last instance of GstVaapiVideoAllocator gets released before
a dangling GstVaapiVideoMemory object, thus possibly leading to a crash.
Always perform conversion of sources buffers to NV12 since this is
the way we tested for this capability in ensure_allowed_caps(). This
also saves memory bandwidth for further rendering. However, this may
not preserve quality since the YUV buffers are down-sampled to 4:2:0.
This fixes direct linking of vaapidownload element to xvimagesink with
VA drivers supporting vaGetImage() from the native VA surface format to
a different VA image format. i.e. color conversion during download.

The image is now expressed as a standard GstVideoFormat, which is not
a FOURCC but rather a regular enum value.
This is a regression introduced in commit 09397fa.
Fix gst_vaapi_uploader_get_buffer() to not assign caps since they
were already negotiated beforehand, and they are not used from the
buffer in upstream elements.
Clean-up gst_vaapi_uploader_ensure_caps() to use the new image caps
represented as a GstVideoInfo.
Adapt GstVaapiVideoMemory allocator to support creation of VA surfaces
with an explicit pixel format. This allows for direct rendering to
VA surface memory from a software decoder.
Get rid of GstCaps to create surface/image pool, and use GstVideoInfo
structures instead. Those are smaller, and allows for streamlining
libgstvaapi more.
Fix creation of GLX texture, to not depend on the GstCaps video size that
could be wrong, especially in presence of frame cropping. So, use the size
from the source VA surfaces.
An optimization could be to reduce the texture size to the actual visible
size on screen. i.e. scale down the texture size to match the screen dimensions,
while preserving the VA surface aspect ratio. However, some VA drivers don't
honour that.
Add support for GstVideoCropMeta in GStreamer >= 1.0.x builds and gst-vaapi
specific meta information to hold video cropping details. Make the sink
support video cropping in X11 and GLX modes.
Some video clips may have a clipping region that needs to propogate to
the renderer. These helper functions make it possible to attach that
clipping region, as a GstVaapiRectangle, the the video meta associated

Now that VA/GLX capable buffers are generated by default on X11, thus
depending on a VA/GLX display, we stil want to use vaPutSurface() for
rendering since it is faster.
Anyway, OpenGL rendering in vaapisink was only meant for testing and
enabling "fancy" effects to play with. This has no real value. So,
disable OpenGL rendering by default.
If the gstreamer-vaapi plug-in elements are built with GLX support, then
try to allocate a GstVaapiDisplayGLX first before resorting to a VA/X11
display next.

Allow plain gst_buffer_map() interface to work with gstreamer-vaapi
video buffers, i.e. expose the underlying GstVaapiSurfaceProxy to the
caller. This is the only sensible enough thing to do in this mode as
the underlying surface pixels need to be extracted through an explicit
call to the gst_video_frame_map() function instead.
A possible use-case of this is to implement a "handoff" signal handler
to fakesink or identity element for further processing.
Fix gst_vaapi_video_allocator_new() to silently check for direct-rendering
mode support, and not trigger fatal-criticals if either test surface or
image could not be created. Typical case: pixel format mismatch, e.g. NV12
supported by most hardware vs. I420 supported by most software decoders.
On map, ensure we have GST_MAP_WRITE flags since this is only what we
support for now. Likewise, on unmap, make sure that the VA image is
unmapped for either read or write, while still committing it to the
VA surface if write was requested.
