This reverts commit 9ef1346b1f.
Way to much for one commit and I'm not sure we want to get rid of the pad caps
just like that. It's nice to have the buffer and its type in onw nice bundle
without having to drag the complete context with it.
Add a method to perform get_range typefinding that also uses the
uri/location extension as an extra hint. It will first try to call the
typefind functions of the factories that handle the given extension. The result
is that in the common case, we only call one typefind function, which speeds up
the typefinding a lot.
This avoids having to do the sorting everytime we use typefind
The behaviour of gst_type_find_factory_get_list has subtlely changed
in the sense that the order was previously undefined, whereas now
it returns them sorted by rank and then by name.
The list against which we run the comparefunc will only contain
GstPluginFeature, therefore remove the 6 expensive type checks we do
for every single comparision.
Original commit message from CVS:
* docs/design/part-negotiation.txt:
Update the docs some more.
* libs/gst/base/gsttypefindhelper.c: (helper_find_peek):
If we pull a buffer with non-trivial caps, suggest those caps with the
max probability.
Original commit message from CVS:
* libs/gst/base/gsttypefindhelper.c: (helper_find_peek):
Increase code readability.
Don't try to compare buffer offsets when ther are invalid.
Original commit message from CVS:
* libs/gst/base/gsttypefindhelper.c: (helper_find_peek):
Sort buffer cache list by end offsets. This makes sure that we don't
stop to search for a cached buffer that contains the requested data
too early.
Also read a minimum of 4k bytes instead of 512 bytes as this is a bit
more efficient. Fixes bug #459862.
Original commit message from CVS:
* libs/gst/base/gsttypefindhelper.c: (buf_helper_find_peek):
Fix off-by-one bug that would only allow peeks of N-1 bytes
from the start even if the buffer to typefind on contains
in fact N bytes of data (makes vorbis typefinding from a
vorbis identification header buffer work).
* tests/check/Makefile.am:
* tests/check/libs/.cvsignore:
* tests/check/libs/typefindhelper.c: (GST_START_TEST),
(gst_typefindhelper_suite), (main), (foobar_typefind),
(plugin_init):
Add very basic unit test for gst_type_find_helper_for_buffer()
that checks for the problem fixed above.

Make sure gstprivate.h and/or config.h are
always included first, otherwise some of our
defines (like _FILE_OFFSET_BITS) might be
redefined in the system headers. Fixes build
on opensolaris (#340016).
Original commit message from CVS:
* libs/gst/base/gsttypefindhelper.c: (helper_find_get_length),
(gst_type_find_helper_get_range):
If we are provided with the size, we should implement
GstTypeFind::get_length, so that typefind functions who
want to can actually peek at the middle of a file.
Original commit message from CVS:
* libs/gst/base/gsttypefindhelper.c: (type_find_factory_rank_cmp),
(gst_type_find_helper):
Try typefinding factories with the highest rank first.
Original commit message from CVS:
* docs/libs/gstreamer-libs-docs.sgml:

Add section for typefind helper and add documentation
for the old and the new function.
Original commit message from CVS:
* gst/base/gsttypefindhelper.c: (helper_find_peek),
(gst_type_find_helper):
Check whether we have the requested data already in our list of
cached buffers before pulling a new buffer; also make the buffer
list a GSList. Speeds up typefinding by ca. 5-10% altogether.
Original commit message from CVS:
* gst/base/gsttypefindhelper.c: (helper_find_peek):
Fix evil typefind crasher: getrange() might return a short
buffer at the end of a file, but gst_type_find_peek() must
either return the full data as requested or NULL, but
never a short buffer.

Extra debug output. Don't segfault on GST_PAD_GETRANGEFUNC = NULL

Migrate part of the docs from the SGML file. Wait for ensonic to
tell me how I did it wrong ;)
* tools/gst-typefind.c: (main):
Extra robustness to state changes between files.
Original commit message from CVS:
* gst/base/gsttypefindhelper.c: (helper_find_peek),
(gst_type_find_helper):
The memory returned by gst_type_find_peek() needs to
stay valid until the end of a typefind function, and
typefind functions may keep results from different
offsets around, so we can't just unref the buffer from
the previous _peek(), but have to save all buffers
returned by _peek() until typefinding is done and only
free them then.

* gst/gstutils.c: RPAD fixes all around.
(gst_element_link_pads): Refcounting fixes.
* tools/gst-inspect.c:
* tools/gst-xmlinspect.c:
* parse/grammar.y:
* gst/base/gsttypefindhelper.c:
* gst/base/gstbasesink.c:
* gst/gstqueue.c: RPAD fixes.
* gst/gstghostpad.h:
* gst/gstghostpad.c: New ghost pad implementation as full proxy
pads. The tricky thing is they provide both source and sink
interfaces, since they proxy the internal pad for the external
pad, and vice versa. Implement with lower-level ProxyPad objects,
with the interior proxy pad as a child of the exterior ghost pad.
Should write a doc on this.
* gst/gstpad.h: s/RPAD/PAD/, s/RealPad/Pad/.
(gst_pad_set_name, gst_pad_set_parent): Macros removed, use
gst_object API.
* gst/gstpad.c: Big changes. No more stub base GstPad, now all
pads are real pads. No ghost pads in this file. Not documenting
the myriad s/RPAD/PAD/ and REALIZE fixes.
(gst_pad_class_init): Add properties for "direction" and
"template". Both are construct-only, so they can't change during
the life of the pad. Fixes properly deriving from GstPad.
(gst_pad_custom_new, gst_pad_custom_new_from_template): Gone. For
derived objects, just set properties when creating the objects via
g_object_new.
(gst_pad_get_parent): Implement as a function, return NULL if the
parent is not an element.
(gst_pad_get_real_parent, gst_pad_add_ghost_pad)
(gst_pad_remove_ghost_pad, gst_pad_realize): Removed.
* gst/gstobject.c (gst_object_class_init): Make name a construct
property. Don't set it in the object init.
* gst/gstelement.c (gst_element_add_pad): Don't allow adding pads
with UNKNOWN direction.
(gst_element_add_ghost_pad): Remove non-orthogonal API. Replace
with gst_element_add_pad (e, gst_ghost_pad_new (name, pad)).
(gst_element_remove_pad): Remove ghost-pad special cases.
(gst_element_pads_activate): Remove rpad cruft.
* gst/gstbin.c (gst_bin_change_state): Use gst_pad_get_parent to
catch the pad's-parent-not-an-element case.
* gst/gst.h: Include gstghostpad.h.
* gst/gst.c (init_post): No more real, ghost pads.
* gst/Makefile.am: Add gstghostpad.[ch].
* check/Makefile.am:
* check/gst/gstbin.c:
* check/gst/gstghostpad.c (test_ghost_pads): Check that linking
into a bin creates ghost pads, and that the refcounts are right.
Partly moved from gstbin.c.
