no libgstkaldionline2.so but libgstkaldinnet2onlinedecoder.so

[zlinsmile]

ubuntu 16.04
python 2.7.12

After i finished do this:
KALDI_ROOT=/path/of/kaldi-trunk make depend
KALDI_ROOT=/path/of/kaldi-trunk make
i just got libgstkaldinnet2onlinedecoder.so, and there is no 'libgstkaldionline2.so'

and then i can not do this GST_PLUGIN_PATH=. gst-inspect-1.0 kaldinnet2onlinedecoder ,it result in

No such element or plugin 'kaldinnet2onlinedecoder'

but i can do this:GST_PLUGIN_PATH=. gst-inspect-1.0 libgstkaldinnet2onlinedecoder.so
and i got that：

Plugin Details:

Version 0.0.0
License BLACKLIST

0 features:

in my gst-kaldi-nnet2-online/src is that:
ls /home/2017/zhanglin/gst-kaldi-nnet2-online/src

Makefile gstkaldinnet2onlinedecoder.cc kaldimarshal.h simple-options-gst.cc
gst-audio-source.cc gstkaldinnet2onlinedecoder.h kaldimarshal.list simple-options-gst.h
gst-audio-source.h gstkaldinnet2onlinedecoder.o kaldimarshal.o simple-options-gst.o
gst-audio-source.o kaldimarshal.cc libgstkaldinnet2onlinedecoder.so

next, i continue to install kaldi-gstreamer-server

And then, i just export my GST_PLUGIN_PATH like this : GST_PLUGIN_PATH=/home/2017/zhanglin/gst-kaldi-nnet2-online/src

then when i start my master and work for online , but i got this:

Traceback (most recent call last):

AttributeError: 'NoneType' object has no attribute 'set_property'

My folder also contains only libgstkaldinnet2onlinedecoder.so (no other so) and everything works fine.
I can run successfully "GST_PLUGIN_PATH=. gst-inspect-1.0 kaldinnet2onlinedecoder".

The worker failure is expected. When you try to load the object kaldinnet2onlinedecoder it fails and return None. After that you try to set the properties of this None object.
I don't think that you need/want to try the gstreamer server before you can successfully run the gst-inspect command.

Are you sure that the make command was successfully finished?
Do you see any errors?
