In case of pkg-config we need to create the include directories object
from the path using include_directories(). For INTELMEDIASDKROOT or
MFX_HOME we need to add the alternate include path ./include/mfx as
Intel MediaSDK now puts the headers there.
To allow curlhttpsrc to support DASH streams that use the on-demand
profile, it needs to support HTTP Range GETs. In GStreamer, the RANGE
is specified by issuing a GST_FORMAT_BYTES seek to set the start and
end of the range. curlhttpsrc needs to implement seek and set the
appropriate curl options to make it add the Range header to the
request.
Currently tsdemux timestamps only the PTS, and only issues the DTS if
it's different. In that case, parsers tend to estimate the next DTS
based on the previous DTS and the duration, which can accumulate
rounding errors.
Clean up path objects nicely when shutting down,
first by dropping pointers to elements during dispose,
and then by making sure to drop the ref to the path object
when finalizing the switch bin.
Fixes valgrind checks in the unit test.
The symbol visibility=hidden flag was only being applied to C
compilation, so plugins implemented in C++ would leak extra symbols
than the 2 _get_desc() and _register().
That also showed that the gst-libs opencv C++ lib was not marking
symbols for export correctly because the BUILDING_GST_OPENCV define
wasn't in the C++ args, so fix that too.
Coverity rightly complains that checking a pointer for NULL after
dereferencing it is pointless.
Remove the check, and to be safe, assert that gst_buffer_add_meta
returns non-NULL.

The message buffers are created using `gst_rtmp_message_new` and thus
always contain a GstRtmpMeta. Add checks to appease Coverity's static
analysis.

This adds a check to avoid draining when the imported buffers are in
fact own by kmssink. This happens since we export our kms buffer as
DMABuf. They are not really imported back as we pre-fill the cache,
but uses the same format as if they were external. This fixes
performance issues seen with videocrop2-test (found in -good).
Draining systematically on caps changes was a hack. Instead, properly
save the render information used to render last_render, and use that
information to drain. This fixes performance issues met with video crop
meta and per frame caps changes.
According to the spec, the least significant bit is reserved and should
always we set to 1. Though, some wrong file has been found. Considering
how low important this reserved bit is, relax the validation.

The major functionality gain this provides is proper reference counting
for a descriptor set. Overall this allows us to create descriptor sets
when they are needed (or reused from a cache) without violating any of
vulkan's object synchronisation requirements.
As there are a fixed number of sets available in a pool, the number of
descriptors in elements is currently hardcoded to 32. This can be extended
in a future change to create pools on the fly if that limit is ever overrun.
Allows a cleaner control flow when there is no fence available for use
with the trash list. An always signalled fence type will always return
TRUE for gst_vulkan_fence_is_signalled.
Serve two purposes:
1. refcounting of vulkan handles with associated destruction. When
combined with the trash list, the user can ensure destruction at
the correct time according to the vulkan rules.
2. avoids polluting our API with 32-bit vs 64-bit integer/pointers
differences as exposed through the vulkan API. on 32-bit, vulkan
non-dispatchable handles are 64-bit integers and on 64-bit, they
are pointers.
