This queries port roles from the LV2 data and converts it into GStreamer
channel positions. This should allow any type of multi-channel plugin
(including beyond stereo, e.g. surround) to work fine in GStreamer,
and with elements that require channel positions to be explicitly stated.
Install the headers, version the library with @GST_MAJORMINOR@,
add all required libraries to _LIBADD instead of _LDFLAGS,
and add GST_*_LDFLAGS to _LDFLAGS.
Fixes bug #594715.
- Separate gstsignalprocessor into a separate library (not sure if this
is in the right place, but it works for now anyway)
- Create LV2 element based on LADSPA element, port most discovery
functionality
Use glib defines for searchpath separators. Filter searchpath to avoid scanning
path entries twice. Fix the return in ladspa_plugin_directory_search to return
wheter we found a plugin.
Move the two function from search.c into gstladspa.c and make them static.
Remove non needed arguments from function prototypes. Use glib api for
simplicity and portability.

Based on Patch by: Brian Cameron <brian dot cameron at sun dot com>
* ext/ladspa/search.c: (LADSPAPluginSearch):
Avoid searching (null) paths or crashing on platforms where printing a
NULL string segfaults. Fixes#567004.
Original commit message from CVS:

Whitespace.
* ext/ladspa/gstsignalprocessor.c:
Add a FIXME:. not sure if this code does the forwarding correctly.
Original commit message from CVS:
* configure.ac:
* ext/ladspa/Makefile.am:
Link the ladspa plugin with -ldl. It's needed for dlopen() and friends
for loading the ladspa plugins and previously was linked in by
gmodule. Fixes bug #543848.
Original commit message from CVS:
* ext/ladspa/gstladspa.c: (gst_ladspa_base_init),
(gst_ladspa_class_init), (ladspa_describe_plugin), (plugin_init):
Don't use GST_BOILERPLATE as the stuff generated from it is not used
anyway and can't be used.
Store the class struct of the correct type in parent_class.
Pass the LADSPA_Descriptor as class_data to the class_init function
as preparation for the time, when we can add pad templates and friends
in class_init and add a FIXME for that.
Don't use a custom hash table for passing the LADSPA_Descriptors to
base_init but use g_type_set_qdata and g_type_get_qdata.
Original commit message from CVS:
* ext/ladspa/gstsignalprocessor.c:
(gst_signal_processor_class_add_pad_template):
Don't unref the pad template after adding it.
gst_element_class_add_pad_template takes ownership of it.

* ext/ladspa/gstsignalprocessor.c (gst_signal_processor_fixate)
(gst_signal_processor_ouija_caps, gst_signal_processor_prepare):
Remove fixate/ouija stuff, thankfully, due to the new
part-negotiation.txt pull-mode negotiation scheme.
(gst_signal_processor_setcaps_pull)
(gst_signal_processor_setcaps): Implement upstream set_caps pull
proxying for pull mode. Now this works: ladspa-sine-fcac !

(gst_signal_processor_ouija_caps): Move around in the source
file...
(gst_signal_processor_prepare, gst_signal_processor_do_pulls):
Call ouija_caps in prepare() instead of do_pulls(), a bit earlier.
This allows us to have caps when we do the pad_alloc_buffer().
(gst_pad_alloc_buffer_and_set_caps): Use self->caps instead of the
pad caps, which might not be set yet.

(gst_signal_processor_add_pad_from_template)
(gst_signal_processor_fixate): Add a fixate function, to assist in
pathological ladspa-sine-fcac ! fakesink can-activate-pull=true
cases.
(gst_signal_processor_prepare, gst_signal_processor_process): Add
nframes args so that getrange can tell ladspa how many frames to
process.
(gst_signal_processor_ouija_caps): setcaps needs to be called
before processing, which normally happens when chaining a buffer
to a pad. However in getrange mode with no sinks we need to check
explicitly for this condition, guess some caps to use, and use
those to setcaps(). Hence this mystical function.
(gst_signal_processor_do_pulls): Pull in bytes, not samples.
Divine the caps if necessary.
(gst_signal_processor_getrange): Interpret the length as bytes,
not samples.
(gst_signal_processor_chain): nframes=G_MAXUINT, will be limited
by incoming buffer sizes.

Reset flow_state back to _OK after a flush stop so that we exit our
error state after the flush. Fixes#374213
Original commit message from CVS:

Convert ' ' into '_'. Try to keep as many characters in the padtemplate
names as possible.
Original commit message from CVS:

A push() gives away our refcount so we should not use the buffer on the
pen anymore.

* ext/ladspa/gstsignalprocessor.h: Add infrastructure for storing
whether a processor can work in place or not, and for keeping

"state" to "flow_state", all callers changed.

(gst_signal_processor_change_state): Stop and cleanup the
processor as we go to NULL.
* ext/ladspa/gstladspa.c (gst_ladspa_base_init): Reuse buffers if
INPLACE_BROKEN is not set.
* ext/ladspa/gstsignalprocessor.c (gst_signal_processor_prepare):

Original commit message from CVS:
second batch :
remove ',' at end of enums as they could confuse older gcc, foreign compilers (forte) and gtk-doc
(in gst-plugins/ext/ this time)
Original commit message from CVS:
Remove all config.h includes from header files, add it to each source file and remove duplicate config.h includes from several source files
Original commit message from CVS:
Fix this too. Note that the per-plugin licensing is gone because of company's new per-plugin (rather than per-element) API. We basically need both... Ohwell, I just want this stuff to compile.
Original commit message from CVS:
merge TYPEFIND branch. Major changes:
- totally reworked type(find) system
- all typefind functions are in gst/typefind now
- more typefind functions then before
- some plugins might fail to compile now because I don't have them installed and they
a) require bytestream or
b) haven't had their typefind fixed.
Please fix those plugins and put the typefind functions into gst/typefind if they don't have dependencies
Original commit message from CVS:
New typefind system:
* bytestream is now part of the core
* all plugins have been modified to use this new typefind system
* asf typefinding added
* mpeg video stream typefiding removed because it's broken
* duplicate typefind entries removed
* extra id3 typefinding added, because we've seen 4 types of files
(riff/wav, flac, vorbis, mp3) with id3 headers and each of these needs
to work. Instead, I've added an id3 element and let it redo typefiding
after the id3 header. this needs a hack because spider only typefinds
once. We can remove this hack once spider supports multiple typefinds.
* with all this, mp3 typefinding is semi-rewritten
* id3 typefinding in flac/vorbis is removed, it's no longer needed
* fixed spider and gst-typefind to use this, too.
* Other general cleanups
Original commit message from CVS:
* actually recurse into sndfile if we are able
* big ladspa cleanups, mainly to comply with the buffer-frames caps property, but also general
cleanups
- the samplerate prop is gone, if you want to set it explicitly (as in for get-based plugins)
you need to use a filtered connection, just like with buffer-frames
* big float2int and int2float changes for buffer-frames compatibility - I think it's quite a bit
simpler
* make the ossclock general, add it to gstaudio, and use it in sndfile as well
i need to update mimetypes, but that's coming soon. there are some other plugins that don't
support buffer-frames, i guess i need to get around to fixing them as well.
Original commit message from CVS:
New mimetypes gone into effect today - this commit changes all old mimetypes over to the new mimetypes spec as described in the previous commit's document. Note: some plugins will break, some pipelines will break, expect HEAD to be broken or at least not 100% working for a few days, but don't forget to report bugs
Original commit message from CVS:
compatibility fix for new GST_DEBUG stuff.
Includes fixes for missing includes for config.h and unistd.h
I only ensured for plugins I can build that they work, so if some of them are still broken, you gotta fix them yourselves unfortunately.
Original commit message from CVS:
another batch of connect->link fixes
please let me know about issues
and please refrain of making them yourself, so that I don't spend double
the time resolving conflicts
Original commit message from CVS:
* fix to adder: don't pull on unusable pads
* fix to ladspa: get output buffers first, so we can know how many frames to
process
- this breaks inplace buffer stuff, hmm
* fix to float2int: add a bufferpool with the same nframes as the source pad's
pool -> no extra latency
