Make appsrc not set caps on buffers when its own caps is NULL.
This avoids calling make_metadata_writable on all buffers and
prevents losing buffer caps in case we are not replacing it
with something meaningful.

While the doc parser allows for certain variation, it is a good idea to not
use random characters here and there, but try to stick to the little markup
syntax there is.
Binding generators apparently need this as they can't really know
that the callback is guaranteed to be called exactly once and that
the user_data can be freed at the end of it.
And deprecate the gulong versions. This is to support platforms
where sizeof(unsigned long) < sizeof(void *). Fixes#627565.

There will always be only a single output buffer and if the
target caps have a different framerate than the input there
will be a negotiation error during conversion.
Add methods to convert between uri and sdpmessages, loosly based on

Don't take an extra ref on the sink and source because that creates a reference
cycle. Instead, use the invalidate method of the clock when the sink and source
are freed. This way, we don't call into the time function anymore after the
objects are disposed.
This is pretty much an FAQ, so try to make the error message a bit
more helpful. Also, don't tell people to file a bug in bugzilla
about this (which is what happens if the default error message for
CORE_NEGOTIATION is used).
Adds mappings from:
GST_TAG_CAPTURING_EXPOSURE_PROGRAM -> ExposureProgram
GST_TAG_CAPTURING_EXPOSURE_MODE -> ExposureMode
GST_TAG_CAPTURING_SCENE_CAPTURE_TYPE -> SceneCaptureType
GST_TAG_CAPTURING_GAIN_ADJUSTMENT -> GainControl
GST_TAG_CAPTURING_WHITE_BALANCE -> WhiteBalance
GST_TAG_CAPTURING_CONTRAST -> Constrast
GST_TAG_CAPTURING_SATURATION -> Saturation
Also renames gst_tag_image_orientation_from_exif_value and
gst_tag_image_orientation_to_exif_value to remove the 'gst'
prefix and not including in the win32 defs.
Tests included.
Adds a new tag for informing if flash was used while
capturing an image and the flash mode selected by the
user during this capture

When calling gobject-introspection scanner, make sure our own
freshly-built libs within the source tree (well, build dir) come
first in the PKG_CONFIG_PATH. May or may not help to make sure
that it doesn't pick up older external plugins-base libs (or
.gir files) from outside the source tree / build directory as
dependencies of the introspected lib instead of using the
stuff we just built in a sibling directory.

Change "Src" into "Source" (we use that elsewhere). I did not keept "Src" as it
is quite unlikely that someone plugs appsrc by searching the registry by classification.
Do not use the result of inner ifd's parsing to increment
the current tag index. The reasons are:
1) The function returns a boolean.
2) The inner ifd's tags are in a separate table, so they shouldn't
interfere with its parent ifd table parsing.
Makes the xmp helper lib aware that the tags can be simple,
sequences or bags (there is still struct and alt, but those
aren't handled yet). Adding this info makes serialization
and deserialization more consistent.
If we find a bag of tags of type string in the xmp packet, we
should concat them, this is not the ideal approach, but at
least works for now as we don't know what type of tag it
is (simple, structure, seq, alt or bag)
Everything in the xmp helper lib is initiallized once and on a thread
safe way, and after that there are only reads going on, no more
writing. Based on that, drop the locking.
So people can check what version of the gst-plugins-base libs they're
building against or linked against.

Elements usually use their own instance as instance data but the
clock can have a longer lifetime than their elements and the clock
doesn't own a reference of the element.
Fixes bug #623807.
Check for the state of the ringbuffer before doing the checks of the other
buffer properties, when we're not started, we don't care about those values.
Adds mappings for:
GST_TAG_GEO_LOCATION_CAPTURE_DIRECTION
GST_TAG_GEO_LOCATION_MOVEMENT_DIRECTION
GST_TAG_GEO_LOCATION_MOVEMENT_SPEED
GST_TAG_GEO_LOCATION_ELEVATION
Does some refactoring in the code to reduce number of parameters
passed to functions
Tests included.
Adds exif helper lib functions to parse exif buffers from/to
taglists. Exif is tipically used in jpeg images, but it can
also be embedded into TIFF, AVI and WAV formats.
Adds a couple function to handle exif in tiff header structures, that is how
exif is embedded in jpeg and (obviously) in tiff.

API: gst_tag_list_to_exif_buffer_with_tiff_header
