Instead of checking for valid utf-8 element-details every time we create
elements (from plugin-init or registry), do it before we save the registry.
Fixes#656193.
The feature name is not supposed to change over time anyway. In order to enforce
this parentize features to the registry and make the feature->name pointing to
GstObject:name. In 0.11 we could consider of removing the feature->name variable
(FIXME comment added).
Fixes: #459466
Add a GstStructure to GstElementClass and GstElementFactory. Add setters/getter.
Handle it in the registry code. Print items in gst-inspect.
Fixes#396774.
API: gst_element_class_set_meta_data(), gst_element_factory_get_meta_data_detail()
Strings in the binary registry are NUL-terminated, so we can just use them
directly if we only need them temporarily, and avoid unnecessary mallocs
and frees.
The logic to handle short reads/writes was incorrect, causing the
packet handler to attempt to handle incomplete packets.
Grow the packet transmit buffer in proportion to observed usage,
causing fewer reallocs.
Add some more debug in the registry chunks code.
This avoids:
* triple-checking for the GType when type-checking is enabled (see #597260)
* Avoids going through an expensive no-argument checking which landed in
glib-2.22
* Avoids going through 2 extrac functions (g_object_new -> g_object_new_valist)
Fix an off-by-one error in the size guard for unpack_element, and
improve various debug statements in the failure paths.
Also, swap some g_new0 to g_malloc0 for the fun of it.
