Plugins can provide a set of named values for a control port. Ideally only those
values are set for the property. Check if all scalepoints are integers and if so
generate an enum type.
- add using namespace std; for std::vector
- use the cpp header imgproc.hpp file for the cv::ellipse function instead of
the C header
- Mat no longer takes IplImage in it's constructors, use the cvarrtomat()
function instead.
Fixes a couple of build errors:

We can avoid a render pass if downstream supports the affine transformation meta
and increase the performance of some pipelines involving gltransformation.
Implemented by checking for the affine transformation in the allocation query
from downstream and combining our matrix with that of upstream's (or creating
our own).
Provide a function to get the affine matrix in the meta in terms of NDC
coordinates and use as a standard opengl matrix.
Also advertise support for the affine transformation meta in the allocation
query.
We were always failing the allocation query as a flag was never being set to
signal a successful negotiation. Fix by setting the required flag on a
successful caps event from upstream.
The port was trivial, and according to the NEWS file nothing else has changed,
but it is possible that other API was changed without proper notification.
OpenJPEG upstream has shipped a pkg-config file for the past 4 years, and all
distros should be shipping it by now.

Use the semaphores in the correct place, before and after the submission for
acquiring and presenting the swapchain buffer.
Waiting on the fence that only signals the command buffer completion rather than
the completion of the presentation is racy with the destruction of the vulkan
buffers associated with that image. Wait on the device to be idle instead after
presenting.
1.Porting the exist deinterlace shader and OpenGL callback
to be compatible with OpenGL ES.
2.Add a our blur vertical shader to gldeinterlace.
3.Add a property named “method” to let user choose which
deinterlace function to use. Default to choose blur vertical
method for better performance.
[Matthew Waters]: fix name of greedyh in method property (was greedhy) and port
to git master.

A realtime clock is used in many places, such as deciding which
fragment to select at start up and deciding how long to sleep
before a fragment becomes available. For example dashdemux needs
sample the client's estimate of UTC when selecting where to start
in a live DASH stream.
The problem with dashdemux calculating the client's idea of UTC is
that it makes it difficult to create unit tests, because the passage
of time is a factor in the test.
This commit changes dashdemux and adaptivedemux to use the
GstSystemClock, so that a unit test can replace the system clock when
it needs to be able to control the clock.
This commit makes no change to the behaviour under normal usage, as
GstSystemClock is based upon the system time.

When application change pipeline state NULL->READY and then READY->NULL,
glimagesink will not clear glsink->window_id. After that, when application
change state NULL->READY, the new_window_id is equal to window_id, glimagesink
will not set window handle. It will use the internal window but not the window
create by application.

Currently, gst_srtp_dec_sink_setcaps is happy if the "roc" field is not
provided in the caps. If it is not provided the stream will be properly
inserted in the hash table with a default "roc". Then, when the first
buffer arrives validate_buffer will find an existing stream in the hash
table and will not signal request-key, not allowing the user to provide
a "roc".
This patch expects "roc" in gst_srtp_dec_sink_setcaps, if not found a
request-key will be signaled and the user will be able to provide all
the srtp fields, including "roc".
