multiple videocards? upd: with tests

[vadim epstein]

hi, i've seen some activity over here recent months (glad to face it after ~3 yrs of silence).
does anybody have an idea how to use this lib with multi-card setup?
there's SetAdapter feature in SpoutSDK, would be ultracool to have it operating in python lib too (or to know how to call it, if it's there already)

i've managed to add the function calls for adapter control, compiled as explained here https://rusin.work/vjing/tools/spout-for-python, but still didn't make it work end-to-end with multiGPU setup. the lib and Spout don't issue errors anymore, but the final receiver doesn't show anything either.
here is what i did:

Spout.cpp:

#define BOOST_PYTHON_STATIC_LIB
#include "Spout.h"
#include <boost/python.hpp>

BOOST_PYTHON_MODULE(SpoutSDK)
{
	using namespace boost::python;

	class_<SpoutSender>("SpoutSender")
		.def("CreateSender", &SpoutSender::CreateSender)
		.def("GetNumAdapters", &SpoutSender::GetNumAdapters)
		.def("SetAdapter", &SpoutSender::SetAdapter)
		.def("GetAdapter", &SpoutSender::GetAdapter)
		.def("SayHello", &SpoutSender::SayHello)
		.def("SendTexture", &SpoutSender::SendTexture)
		.def("ReleaseSender", &SpoutSender::ReleaseSender)
		;
	class_<SpoutReceiver>("SpoutReceiver")
		.def("pyCreateReceiver", &SpoutReceiver::pyCreateReceiver)
		.def("GetNumAdapters", &SpoutReceiver::GetNumAdapters)
		.def("SetAdapter", &SpoutReceiver::SetAdapter)
		.def("GetAdapter", &SpoutReceiver::GetAdapter)
		.def("pyReceiveTexture", &SpoutReceiver::pyReceiveTexture)
		.def("ReleaseReceiver", &SpoutReceiver::ReleaseReceiver)
		.def("SelectSenderPanel", &SpoutReceiver::SelectSenderPanel)
		.def("GetWidth", &SpoutReceiver::GetWidth)
		.def("GetHeight", &SpoutReceiver::GetHeight)
		;
}

python calls (same for SpoutReceiver):

adapter_num = 1
spout_name = 'source'
width = height = 512
spoutSender = SpoutSDK.SpoutSender()
spoutSender.SetAdapter(adapter_num)
print(' .. Sender on GPU', spoutSender.GetAdapter(), 'of', spoutSender.GetNumAdapters())
spoutSender.CreateSender(spout_name, width, height, 0) 
print(' .. Sender created')

further advices are welcome

here are the compiled libs for all python 3.x versions
