ttml was recently added but it won't compile unless libxml2 version 2.9.2
or later is available. In that version the first parameter of xmlGetProp
switched to being a const. In previous versions the compiler complains
about passing a const value to a non const argument.
This allows pushing the destruction of vulkan resources after the signalling
of an vulkan event. The event facilitates knowing when a specific point in the
vulkan queue has been reached. Only after the event has been signaled can
vulkan resources be freed and/or reused.
The spec allows the core/compatibility profiles to be used
with #version 150.
Also tighten up the tests to check for default profiles being chosen
correctly.
Unfortunately this does not go through the normal state change
machinery, so we don't get notified about this in change_state().
However we need to stop scheduled playback, so that once PLAYING is
reached again we can start scheduled playback with the correct time.
Without this, flushing seeks in PLAYING will not work correctly:
decklinkvideosink will wait before showing the new frames for the amount
of time the pipeline was in PLAYING before.
- DTLSv1_method() is deprecated, and since 1.0.2 replaced by
DTLS_method().
- CRYPTO_set_locking_callback() and CRYPTO_set_id_callback() are
no-ops (empty macros) since 1.1 and are not supposed to be used
anymore.

Drawing is done via the GDI drawing functions. The cursor is
converted to a monochrome version before drawing. This is because
the GDI drawing functions seem to have undefined behavior with
cursor images including an alpha channel.
I could not find any other reliable way to draw these alpha
channel cursors without producing unwanted artifacts. These type
of cursors were introduced with Window Vista when run with it's
Aero theme.
Also adjust the cursor coordinates when capturing non-primary
screens via the "monitor" option.

Consistently use GST_ROUND_UP_4(width) as stride for
bayer buffers. Bayer data will usually come in widths
that are multiples of 4 anyway, so hopefully this
should not have any adverse impact on anyone in
practice.
Before, bayer2rgb required input buffers to are sized
accordingly, but then didn't actually round up when
calculating row offsets. rgb2bayer didn't use a rounded
stride nor buffer size.

If the playlist does not contain any iframe variants then
demux->master->iframe_variants is NULL. If the previous variant is an
iframe variant then there is at least one iframe variant and
demux->master->iframe_variants->data can be safely used.

Changes are:
- Use the wrapper functions to access opaque data types. To preserve
backward compatibility, define fallback definitions
- Remove the use of idiom "pqueue_size(ssl->d1->sent_messages)", since
there is no replacement
- Use RSA_generate_key_ex instead of the deprecated RSA_generate_key

rawvideoparse wouldn't error out on not-negotiated,
but would just keep on going, because it didn't pass
the flow return value back to the parent class and
thus upstream, so the source wouldnt' stop streaming.
The change to use GST_EXPORT for symbols under Windows requires
GST_EXPORTS for internal use, and that is also needed under Autotools.
The same thing is done for gstreamer-1.0.dll in -core.
The calling convention may be deprecated, but we still need it for
OpenGL. The build issue was caused by an incorrect syntax being used for
the WINAPI (__stdcall) prototype in function pointers which was accepted
by GCC but is rejected by MSVC.
It was always wrong since the symbols being exported in gstgl-1.0.dll
are platform-specific, and the check we do in dist checks it on all
platforms (which usually means Linux) and the list is instead
Linux-specific right now.
Even if we fix that, it can still never be right because it depends on
your configuration even on a specific platform. For instance, when we
start building EGL support on Windows using ANGLE, the symbol list will
change depending on whether that is enabled or not.
We also don't need this anymore since we use GST_EXPORT for all
functions exported on Windows now.
MSVC warns about this because it's a C++ compiler, and this actually
results in useful things such as the incorrect 'gboolean' return value
for functions that return GstFlowReturn, so let's do explicit
conversions to reduce the noise and increase its efficacy.
With MSVC, this gives the following warning:
warning C4305: 'function': truncation from 'double' to 'gfloat'
Apparently, MSVC does not figure out what type to use for constants
based on the assignment. This warning is very spammy, so let's try to
fix it.
The error is:
unary minus operator applied to unsigned type, result still unsigned
This is a commonly-done operation in gstreamer and it's done on purpose.
It's just noise.
