1b567af051 libvisual: use gst_element_class_set_metadata when passing dynamic strings
gst_element_class_set_metadata is meant to only be used with
static or inlined strings, which isn't the case for this element
resulting in use-after-free later on.

https://gstreamer.freedesktop.org/documentation/gstreamer/gstelement.html?gi-language=c#gst_element_class_set_static_metadata

5c4f4ac1bd Add support for Meson as alternative/parallel build system
https://github.com/mesonbuild/meson

With contributions from:

Tim-Philipp Müller <tim@centricular.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.

ba9bf26f4b libvisual: Factor out endian-order RGB formats

725906bb71 audiovisualizer: don't use private GMutex implementation details
Don't use private GMutex implementation details to check
whether it has been freed already or not. Just turn dispose
function into finalize function which will only be called
once, that way we can just clear the mutex unconditionally.

d3a73827e0 Revert "visual: remove unnecessary variable"
This reverts commit a91d521a36.

Being a base class it is better to check the value instead of ignoring it since
a child class could be created that returns valuable information.

a91d521a36 visual: remove unnecessary variable
klass->setup (scope) will always return TRUE since all children of this class
do so, no need to store the return. Besides, the value is overwritten a few
lines down before it is ever used. Save the unnecessary memory and instructions.

4f1ba51c4b visualizer: handle non-existant pool in the default allocation query
gst_query_set_nth_allocation_pool() requires there to be a pool in the
query already. This is not always the case when we get the query from
upstream.  Use gst_query_add_allocation_pool() instead in such case.

c480bac5b7 libvisual: fix improper video frame clear operation
The current code is memsetting the GstVideoFrame.data address to 0s (which
causes a segfault). This member is actually an array of data buffers (one for
each plane).  This fix iterates over each data plane to clear them all.

16c185bac6 libvisual: fix crashes and invalid writes in totem
This reverts part of "visual: enable commented out code again."
(commit 8222ba16c8).

The shader code does indeed look broken (or rather,
it makes assumptions that are not necessarily true here,
namly that pixel stride is 4, for example), which
makes totem very crashy and causes other weird behaviour.
