For pre-1.1.x openssl, a callback to set the thread id needs to be
provided to openssl. In 0.9.x the thread id was an unsigned long. In
1.0.x it was expanded to be able to hold a void*. Here we change to use
the 1.0.x API so that the thread id can always hold a GThread*, even on
platforms like msvc x64 where unsigned long is only 32 bits.
All of this is still #ifdef'd out of existence when building with
openssl 1.1.x or later which changed the thread API again, and does not
need a thread id callback.

Simply produce the result into the output image provided by the base
class. This avoid useless copy. This also removes unchecked buffer map
and ensure that GstVideoMeta is respected (for stride mostly).

If a sub class of GstGLContext does not create a group
then it currently crashes:

Configure the display mode when setting the negotiated caps instead of
during showing the first frame.
A framebuffer is required to set the mode. Allocate a buffer object
according to the negotiated caps and use it to set the mode. This buffer
object cannot be freed until another page flip happened on the crtc
(i.e., until the first frame is rendered).

The force-modesetting parameter forces the kmssink to ignore already
configured display modes, to configure the display mode itself and use
the base plane for output.

If the input buffers have a different size than the display, the frames
would have to be scaled or positioned on the display. The kmssink cannot
decide which behaviour would be appropriate for which use case.
In order to avoid scaling or positioning of the input stream, allow only
the supported connector resolutions in the sink caps.

Displays usually support multiple modes. Therefore, the kmssink should
not only support the preferred mode, but any mode that is supported by
the display.
https://bugzilla.gnome.org/show_bug.cgi?id=773473
The kmssink assumed that the mode was already set by another application
and used an overlay plane for displaying the frames.
Use the preferred mode of the monitor and render to the base plane if
the crtc does not have a valid mode.

This is a subblass of VideoFilter but yet does not use any of it's
features. This also fixes issue in case the incoming images have custom
strides as the VideoMeta is no longer ignored.

When a MSS server hosts a live stream the fragments listed in the
manifest usually don't have accurate timestamps and duration, except
for the first fragment, which additionally stores timing information
for the few upcoming fragments. In this scenario it is useless to
periodically fetch and update the manifest and the fragments list can
be incrementally built by parsing the first/current fragment.

The schroedinger headers unconditionally #define over C99's rint when
compiling with msvc which messes up the later inclusion of math.h.
Including math.h before schroedinger headers avoids getting syntax
errors in math.h

a) Use get_pkgconfig_variable() to get the opencv prefix
b) Place an upper limit on the opencv version
c) Ensure that headers are available
(b) and (c) just copy what the configure.ac checks do.
First of all, all the HD and UHD modes should be top-field-first, as
also returned by the Decklink mode iterator API.
Then we should include the caps field "field-order" in the caps of the
source (not the sink due to negotiation problems with optional fields).
And finally we should set the TFF flag on interlaced buffers that are
top-field-first.
On some hardware the first few frames are bogus and not very useful.
Their timestamps are off, they have no timecodes, or there are spurious
black frames / no-signal frames. After a few frames this stabilizes
though.

Based on this we calculate the actual capture time, which should get us
rid of any capturing jitter by averaging it out.
Also add a output-stream-time property which forces the elements to
output the stream time directly instead of doing any conversion to the
pipeline clock. Use with care.
