47fd993d4d memory: log with GST_INFO instead GST_ERROR when subclass map failed.
Add unit test to ensure that.

It can be a normal execution path to do some map trials and there is
no need to worry the user in that case.

The application has to check the return value of gst_memory_map.

06b015b62a utils: use temp var in fallback GST_WRITE_*() macros
To make sure the value is only expanded/used once, in case
there are side effects to it, and to avoid calculating it
or looking it up multiple times if there is a calculation
or lookup involved.

075744a894 Cast away const from GstMetaInfo in *_get_meta_info() functions
MSVC warns about the const in the implicit argument conversion in the
calls to g_once_init_{enter,leave}. It's OK so explicitly cast it.

584da6e86c taglist: remove return void in gst_tag_register

5a5ae1be1f parse-launch: Support linking all pads with new operator
Introduce a new operator ':' - e.g. element1 ':' element2

For example, 'uridecodebin : encodebin' -
if the encodebin has multiple profiles compatible with the
decodebin, multiple links will be created.

With '!' , after one delayed link is successfully done, the
pad-added callback is disconnected.

e1dc60524e dynamic types: Implement dynamic types in the registry
Implement GstDynamicTypeFactory as a new registry feature.

GstDynamicTypeFactory provides a way of registering a GType
into the registry, such that it will be registered as a dynamic
type when the registry is loaded, and then automatically loaded
if the type is needed during caps parsing.

This allows using non-core types in pad templates, by loading a
registry feature to create the GType on the fly.

287645c2d7 info: Replace %p and %r in GST_DEBUG_FILE
It's useful to be able to set a name pattern for GST_DEBUG_FILE so that
the same environment variable can be used for multiple processes and
still write to different files. Especially useful if these processes
run simultaneously.

%p: Replaced with PID
%r: Replaced with random number

%p is obviously useful. %r is useful when for instance running two
processes with same PID but in different containers.

83cac0f7b6 pad: add no-reconfigure link check
Enable it to prevent sending reconfigure when linking elements.

Useful for autoplugging when we know caps or bufferpools shouldn't change
to save doing caps renegotiation to end up with the same final scenario.

The no-reconfigure is not a proper check, it is a flag. It is implemented
as a GstPadLinkCheck to avoid creating another gst_pad_link variant.

This forces gstenumtypes.h to be built whenever something uses gst_dep

gstenumtypes.h

actually a Meson bug.

b6e69ffdfb gstconfig: Use __declspec when built with MinGW and linking with MSVC
Earlier we were only using __declspec(dllexport/import) when we were
built with MSVC because when built with MinGW and linking with MinGW we
don't need it (and we get linker errors because of it).

However, when we're built with MinGW and someone wants to link to us
with MSVC, we still need the prototypes to have __declspec(dllimport)
since MSVC cannot do auto-import like GCC can.

1b7ab25512 element: Reset the stop position to NONE in seek_simple()
When using seek_simple() in combination with other kinds of seeks, this
becomes problematic. seek_simple() does not reset the stop position to
GST_CLOCK_TIME_NONE but keeps whatever a previous seek did. So for example
when doing a seek_simple() after a rate=-1 seek, we would usually get
assertions that start>stop (and stop being the old stop from the rate=1 seek).
