gst_util_greatest_common_divisor()
gst_util_double_to_fraction()
gst_util_fraction_to_double()
Using these instead of going over GValue has much lower overhead.
Also add float<->fraction transform functions for GValue.
This returns the internal feature list cookie, which changes every
time a feature is added or removed. This can be used by elements
to check if they should update their cached feature lists.
We currently do a little too much work when we push the first buffer around
resulting in excessive caps checking. We can probably make this a little less
expensive.
This patch adds gst_caps_set_value() and allows gst_caps_set_simple() to
work on non-simple caps. See the API documentation for the functions
about what they do.
The intention of these changes is to ease working with caps in caps
transform functions. An example for this would be ffmpegcolorspace,
where the caps transform function could be changed to look roughly like
this (pseudocode ahead):
result = gst_caps_copy (template_caps);
value = gst_structure_get_value (gst_caps_get_structure (caps, 0),
"widh");
gst_caps_set_value (result, value);
/* same for height, framerate and par */
return caps;
which is much cleaner and easier to understand than the current code.

In most places in core and baseclasses we just need the caps to do caps-
intersections. In that case ref'ed caps are enough (no need to copy).
This patch also switches the code to use the new functions.
API: gst_pad_get_caps_refed(), gst_pad_peer_get_caps_refed()
Add a simple version check when starting the plugin-scanner so we can
verify we're talking to one that talks the same language.
First try a plugin-scanner in the installed path, then try one via the
GST_PLUGIN_SCANNER env var if that doesn't work.
Update the uninstalled script.
Install the plugin-scanner to the libexec dir
Often we don't need the result of the intersection. Add a variant that only
tries to intersect. It can break out earlier and does less GValue copying.
API: gst_caps_can_intersect()
Use more refined search paths for our plugin modules. Not only does
this make things much faster in an uninstalled setup, it also makes
sure we're not accidentally using out-of-date plugins built ages
ago as part of a (failed) 'make distcheck' when we forget to clean
up the distcheck build directory.
There's no need to have GstStreamConsistency in a public header for
the time being, so make it private. While we're at it, add a gtk-doc
blurb for it though. Re-fixes #588744.
