Thibault Saunier a3595f7e0f lv2: Namespace global variables and explicitly make them private 
And fix a LV2_PORT_GROUPS__rearLeft/LV2_PORT_GROUPS__rearRight typo

Debarshi Ray a0cd455dd0 lv2: Make it build with -fno-common 
GCC 10 defaults to -fno-common. This means that global variables shared
across multiple translation units should be declared as 'extern' in
header files and defined in exactly one C file. See:
https://gcc.gnu.org/gcc-10/porting_to.html

Nicolas Dufresne fbd9a62504 lv2: Try and reflect better lilv default path 
While keeping it simple, this patch tries and mimic lilv default path.
It does not matter if some path are duplicated due to symlink because in
the end it's lilv that will walk these paths. The worst case is that we
update our cache more often then strictly needed.

for loading.

Stefan Sauer a1bf2e17cc lv2: support CVPorts 
CVPorts are ports that take a buffer. For now we just fill the buffers with
the control value.

Stefan Sauer b483717322 lv2: cleanup the predicates

Stefan Sauer 3101fe78f9 lvs: add require_feature checks

check which plugins we can no suuport.

Stefan Sauer d7b7d9deb7 lv2: skip plugins that need host features 
We haven't implemented this yet and those plugin would fail when we instantiate
them.

Thibault Saunier c32e74fd8a lv2: Port filters to GStreamer 1.0 and use lilv instead of slv2 
Properly separate files as we will not have only one single base class
for all elements as we used to with 0.10, but the same way it is done
with ladspa, we subclass GstAudioFilter, GstBaseSource etc...

More logging and comments. Rename some vars for consistency. Fully init port
struct.

Stefan Kost 8f1bb31255 lv2: shorter element names 
Cut off the protocol part from the uri. Also just g_Strdup, instead of printf
the name.

Stefan Kost 6aed9cfedb lv2: better gobject properties 
Use lv2:symbol as a base for the property name and lv2:name for nick and blurb.

Stefan Kost faa007d4b0 lv2: create valid gobject property names. Fixes #602528 
We cannot use the names as we get them from lv2 for the gparamspec name, only
for nick/blurb. Apply same algorithms like elsewhere (ladspa) for name.

Stefan Kost 1803eb4d7a lv2: set the audio-channel positions again, but now in _setup 
Readd the code that was reverted for the release. We now set audio-channel
positions if any on the pad caps and not on the templates.
 2009-11-19 23:01:29 +02:00
Stefan Kost d7a4293774 lv2: only use g_return_val_if_fail for checking pre-conditions 
g_return_* can be disabled. Still we want to check for failed instance creation.
 2009-11-19 21:11:35 +02:00
Stefan Kost 8a5e9a3363 signalprocessor: change _setup to pass whole caps and not just sampling_rate 
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.
 2009-11-19 21:11:35 +02:00
Stefan Kost 38592a566d signalprocessor: don't set channel positions in template-caps, Fixes #601775 
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.

Dave Robillard fa47a5ff3a More tolerate port group support, plugin cleanup. 
Gracefully handle plugins with illegal groups that contain no symbol by
treating ports in that group normally (i.e. as if they weren't part of a
group).  The port groups spec mandates that groups have a valid unique
symbol, but plugins aren't perfect...

Make (conceptually) static plugin variables actually (C) static,
and clean up SLV2 related things with a GCC shared library destructor,
if GCC is in use.

Dave Robillard 374d52d257 Multi-channel support with channel positions. 
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.
