Split the introspection and registration part. This way we only need to open all
plugins when updating the registry. When reading the registry we can register
the elements entierly from the cache.
This allows to get rid of the sampling_rate variable in the base-class. Also now
subclasses can modify the caps to actualy negotiate. This is needed to e.g. set
audio-channel positions.
This makes sure that the headers from the source tree are taken and not
accidentially installed system headers in the case of builddir!=srcdir.
Fixes bug #602161.
Revert the changes that added audio positions to template caps. We have an un-
fortunate limitation in core that does not allow to do it. Keep a few things
commented out, so that the channel position can later on be set in setcaps.
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.
Original commit message from CVS:
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:
* ext/ladspa/gstladspa.c:
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.
