Reflow the code to move error handling to the end of the functions. Initialize
gvalue like we do in the setter. Add a unit-test module with two simple tests
the catche this bug.
Init variable to avoid compiler warning and make the build bot happy
(the compiler most likely complains about this because it doesn't know
here that fail_unless will abort/exit in the path where it fails).

GMP only uses "unsigned long int", which is 32 bit
on 32 bit architectures and can't hold a guint64.
This resulted in false unit test failures on 32 bit architectures.
Fixes bug #595133.
This tests 100000 random multiplications/divisions of all scaling
function variants and compares the result with the result that is
generated by GMP on the same input.
For this check for GSL and GMP during configure but only use
it for this single unit test.
Testing functions were provided by Kipp Cannon <kcannon@ligo.caltech.edu>
Make a downstream element return an error after upstream has already
put all data into queue (including EOS). As such, upstream
will not be around to pick up the error, so it is up to queue to
act appropriately. See #589991.
Note there may be downstream fatal errors (e.g. negotiation) that do
not warrant an error message already having been posted.
For now, don't show a g_warning() for empty tag strings and NULL
tags with non-git versions; we should wait for the fixes in our
plugin modules to make it into a release before we enable this
unconditionally.
Don't forbid the empty string "" in generic structures, only in taglists.
Properly allow the NULL string by adding special cases for serialising
and deserialising it. prop1=(string)NULL is the NULL string,
prop1=(string)"NULL" is the actual string with the value "NULL"
Add new method to iterate a bufferlist without having to allocate an iterator.
Add convenience method for getting an item from the list based on the group and
index.
Remove redundant _do_data callback and method.
Update unit-tests and add some more for the new methods.
Add functions to create a new tag list and set tags in one go, which
is nice for use in combination with functions that take ownership of
the taglist, such as gst_event_new_tag() or gst_element_found_tags().
API: add gst_tag_list_new_full()
API: add gst_tag_list_new_full_valist()
Add a pattern scan function similar to the one recently added to
GstAdapter, and a unit test (based on the adapter one).
Fixes#585592.
API: add gst_byte_reader_masked_scan_uint32()
Add a bunch of vararg getter convenience functions to complement
the vararg setter functions, and a basic unit test. Fixes#534208.
API: gst_structure_get()
API: gst_structure_id_get()
API: gst_structure_get_valist()
API: gst_structure_id_get_valist()
Add gst_segment_to_position() that converts a running_time to a position in the
segment. A faulty variant of this function is currently used in inputselector
but we'll need it for frame stepping too.
API: GstSegment::gst_segment_to_position()
Use string_warp/unwrap to escape delimiters, otherwise deserialisation fails.
Also move GST_ASCII_IS_STRING to private header to avoid keeping it in sync.
Also use '\0' when terminating a string for better readability.
GObject may crash if two threads do concurrent g_object_notify() on the same
object. This may happen if fakesink receives an out-of-band event such as
FLUSH_START while processing a buffer or serialised event in the streaming
thread. Since this may happen with the default settings during a common
operation like a seek, and there seems to be little chance of a timely fix
in GObject (see #166020), we should hack around this issue by protecting all
of fakesink's direct g_object_notify() calls with a lock.
Also add unit test for the above.
Fixes#554460.
Also warn if an element or application tries to add a field with an
empty string to a structure (NULL strings are still needed and
allowed though) and do all those checks in the right function.
Fixes#559643.
gst_adapter_masked_scan_uint32 could return values smaller than offset
if the first byte(s) of the mask are 0 and the pattern matches the
beginning of the adapter.
Added examples to documentation of gst_adapter_masked_scan_uint32().
Also added some more masked boundary tests.
Fixes#584118
Add a reasonably optimized new gst_adapter_masked_scan_uint32() function
to scan the adapter for a pattern after applying a mask.
Add some unit tests.
API: GstAdapter::gst_adapter_masked_scan_uint32()
Fixes#583187
Reuse buffer code for bufferlists. Not sure if this measurably impacts performance
for the simple buffer case, if it does after doing some benchmarks, we can
decouple it later.
Fixes#572285
When a are requested to take a buffer from the adapter that is exactly the
headbuffer, don't make a subbuffer of it but return that head buffer.
Add a unit-test for this new optimisation.
Post a stream-status message indicating that a new task was created so that the
application has a chance to change the properties of the task.
Fix unit test to take into account the new ref of the message.
