2c056563bf gstutils: Add helpers to get/set array properties
This is to help bindings access properties of type GST_TYPE_ARRAY.
This function will get/set the property and convert form/to
GValueArray.

New API:
  gst_util_set_object_array
  gst_util_get_object_array

33616d47be info: Add a 'flags' parametter to gst_debug_get_stack_trace
This is an API break but that API has not been released yet.

We are passing a flag rather than a simple boolean as we can imagine
to implement more features in the future for example to retrieve a
stack trace for all the threads, etc..

Retrieving source file and line numbers is pretty
expensive while getting a stack trace, this new argument
allows the user to decide to retrieve a backtrace
without those infos instead which is much faster.

For example running $ GST_LEAKS_TRACER_STACK_TRACE=1 GST_DEBUG=GST_TRACER:7 \
GST_TRACERS=leaks time gst-launch-1.0 videotestsrc num-buffers=1 ! fakesink:

* With simple stack traces:

    0.04s user 0.02s system 99% cpu 0.060 total

* With full stack traces:

    0.66s user 0.23s system 96% cpu 0.926 total

0494c173e0 uri: Add new uri API to get media fragments URI as table
As an usecase of URI fragment, it can indicate temporal or spatial
dimension of a media stream. To easily parse key-value pair,
newly added gst_uri_get_media_fragment_table () API will provide
the table of key-value pair likewise URI query.

da73b89200 element: Add API to more easily post messages about flowing issues
In many parts of the code we raise streaming error when the flow
goes wrong, and each time we create more or less similare error
message. Also that message does not let the application know what
has actually gone wrong. In the new API we add a "flow-return" detail
field inside the GstMessage so that the application has all the information
if it needs it.

API:
    GST_ELEMENT_FLOW_ERROR

3cba95ca2a element: rename gst_element_message_new_details() to gst_make_element_message_details()
Fixes g-i warning "Gst: Constructor return type mismatch
symbol='gst_element_message_new_details' constructed='Gst.Element'
return='Gst.Structure'".

This is a newly-added function in git that has not been in a stable
release yet, so it's fine to rename it. It's also only used indirectly
via macros.

b2f9808722 Add support for Meson as alternative/parallel build system
https://github.com/mesonbuild/meson

With contributions from:

Tim-Philipp Müller <tim@centricular.com>
Mathieu Duponchelle <mathieu.duponchelle@opencreed.com>
Jussi Pakkanen <jpakkane@gmail.com> (original port)

Highlights of the features provided are:
* Faster builds on Linux (~40-50% faster)
* The ability to build with MSVC on Windows
* Generate Visual Studio project files
* Generate XCode project files
* Much faster builds on Windows (on-par with Linux)
* Seriously fast configure and building on embedded

... and many more. For more details see:

http://blog.nirbheek.in/2016/07/building-and-developing-gstreamer-using.html

Building with Meson should work on both Linux and Windows, but may
need a few more tweaks on other operating systems.

8177173db0 element: Add gst_element_call_async()
This calls a function from another thread, asynchronously. This is to be
used for cases when a state change has to be performed from a streaming
thread, directly via gst_element_set_state() or indirectly e.g. via SEEK
events.

Calling those functions directly from the streaming thread will cause
deadlocks in many situations, as they might involve waiting for the
streaming thread to shut down from this very streaming thread.

This is mostly a convenience function around a GThreadPool and is for example
used by GstBin to continue asynchronous state changes.

f876306638 utils: expose pad_link_maybe_ghosting
This is a useful function to automatically add ghost pads when linking
two elements across bin boundaries without know their exact parentage.

e.g. when using gst_parse_bin_from_description (with or without it ghosting pads),
one can simply retreive the src/sink pads from the bin to link to another pad.

Similar functionality is provided by gst_element_link_pads{_full}() however only
by pad name rather than by actual pads.

API: gst_pad_link_maybe_ghosting_full

  gst_element_class_add_pad_template (element_class,
      gst_static_pad_template_get (&some_templ));

which is both confusing and unnecessary. We might just
as well add a function to do that in one step.

10b78d872b tracerrecord: add a log record class
We use this class to register tracer log entry metadata and build a log

This also simplifies the logging code, since that is now a simple varargs
function that is not exposing the implementation details.

Add docs for the new class and basic tests.

Remove the previous log handler.

d5ded15889 bin: implement context propagation when adding elements
When adding an element to a bin we need to propagate the GstContext's
to/from the element.

This moves the GstContext list from GstBin to GstElement and adds
convenience functions to get the currently set list of GstContext's.

This does not deal with the collection of GstContext's propagated
using GST_CONTEXT_QUERY.  Element subclasses are advised to call
gst_element_set_context if they need to propagate GstContext's
received from the context query.
