Enable read and write mappings only if direct-rendering is supported.
Otherwise, this means that we may need to download data from the VA
surface first for correctness, even if the VA surface doesn't need to
be read at all. i.e. sometimes, READWRITE mappings are meant for
surfaces that are written to first, and read afterwards for further
processing.
https://bugzilla.gnome.org/show_bug.cgi?id=704078
Fix check for direct-rendering if the creation of VA surfaces with
an explicit pixel format is not support, e.g. VA-API < 0.34.0, and
that we tried to allocate a VA surface based on the corresponding
chroma type. i.e. in that particular case, we have to make sure that
the derived image has actually the expected format.
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 ensure_operations() to release the VPP operations array if non
NULL, prior to returning to the caller. The former function was also
renamed to a more meaningful get_operations() since the caller owns
the returned array that needs to be released.
Fix first-time operation lookup through find_operation() if the set
of supported operations was not initially determined through the
gst_vaapi_filter_get_operations() helper function.

Don't try to create pixmaps if we have not requested that feature. This
fixes execution for non-X11 backends, and most specifically DRM video
output mode.
Fix calculation of MCU count for image sizes that are not a multiple
of 8 pixels in either dimension, but also for non-common sampling
factors like 4:2:2 in non-interleaved mode.
Add support for images with multiple scans per frame. The Huffman table
can be updated before SOS, and thus possibly requiring multiple uploads
of Huffman tables to the VA driver. So, the latter must be able to cope
with multiple VA buffers of type 'huffman-table' and with the correct
sequential order.
Improve robustness when some expected packets where not received yet
or that were not correctly decoded. For example, don't try to decode
a picture if there was no valid frame headers.
Improve debugging and error messages. Rename a few variables to fit the
existing naming conventions. Change some fatal asserts to non-fatal
error codes.
Split the input buffer data into decoder units that represent a JPEG
segment. Handle scan decoder unit specifically so that it can include
both the scan header (SOS) but also any other ECS or RSTi segment.
That way, we parse the input buffer stream only once at the gst-vaapi
level instead of (i) in gst_vaapi_decoder_jpeg_parse() to split the
stream into frames SOI .. EOI and (ii) in decode_buffer() to further
determine segment boundaries and decode them.
In practice, this is a +15 to +25% performance improvement.
Fix decode_buffer() function to gracefully skip comment (COM) segments.

Fix _getcaps() implementation to not report codecs with size information

As a last resort, if video processing capabilities (VPP) are not available,
or they did not produce anything conclusive enough, then try to fallback to
the original rendering code path whereby the whole VA surface is rendered
as is, no matter of video cropping or deinterlacing requests.
Note: under those conditions, the visual outcome won't be correct but at
least, something gets displayed instead of bailing out.
Try to use VA/VPP processing capabilities to handle video cropping and
additional rendering flags that may not be directly supported by the
underlying hardware when exposing a suitable Wayland buffer for the
supplied VA surface. e.g. deinterlacing, different color primaries than
BT.601, etc.
Update the frame redraw infrastructure with a new FrameState stucture
holds all the necessary information used to display the next pending
surface.
While we are at it, delay the sync operation down to when it is actually
needed. That way, we keep performing additional tasks meanwhile.
Fix creation of GstVaapiVideoBuffer objects (i) to have that type for real;
and (ii) to correctly extract the GstSurfaceConverter from the video buffer
object meta.
This fixes support for cluttersink with GStreamer 0.10 builds.
Disable video cropping in MPEG-2 codec because it is partially implemented
and actually because nobody implements it that way, and the standard spec
does not specify the display process either anyway.
Most notably, there are two possible use cases for sequence_display_extension()
horizontal_display_size & vertical_display_size: (i) guesstimating the
pixel-aspect-ratio, or (ii) implement some kind of span & scan process
in conjunction with picture_display_extension() information.

Other GStreamer sinks, like xvimagesink, have a force-aspect-ratio property,
