I'm using Jetson board and cannot find gstreamer-1.0/ folder...
do you have any experience related with this?

To install manually you need copy, move or symlink the following files

./plugins/libgstpylonsrc.la
./plugins/.libs/libgstpylonsrc.so
to either of these locations:

~/.local/share/gstreamer-1.0/plugins/ if you only want your user to be able to use this plugin
/usr/local/lib/gstreamer-1.0/ if you want this plugin to be available to every user.
Note that these are the default locations which might be different if you installed gstreamer with a custom location prefix.

Which Linux distribution are you running?

The first directory (~/.local/share/gstreamer-1.0/plugins/) must be created manually most of the time. The latter might not exist if you only have the distribution's version of gstreamer. For that the location of plugins depends on where gstreamer is installed, I think (/usr/lib/gstreamer-1.0?).

I managed to find one below. I will try to follow the last instructions.

  1. ubuntu 14.08 for host pc
    /usr/lib/x86_64-linux-gnu/gstreamer-1.0

  2. and Jetson Xavier.
    /usr/lib/aarch64-linux-gnu/gstreamer-1.0

hm, actually I tried it again. I use sudo make install in the gst-pylonsrc/plugins directory.
I think it was installed correctly.

:/usr/local/lib/gstreamer-1.0$ ls -al

You can test it with gst-inspect-1.0 pylonsrc.

gst-launch-1.0 -v pylonsrc camera=1 fps=25 ! bayer2rgb ! nvvidconv ! 'video/x-raw(memory:NVMM), format=NV12' ! omxh265enc ! matroskamux ! filesink location=test_1_265.mp4 -e

it worked fine with above. Thank you.

Depending on your camera you might be able to use the imageformat parameter for pylonsrc to output rgb directly. See supported formats.
