Steps to compile the "gst-nvcompositor" sources natively:
|
||||||
|
|
||||||
|
1) Install gstreamer related packages on target using the command:
|
||||||
|
|
||||||
|
sudo apt-get install libgstreamer1.0-dev \
|
||||||
|
gstreamer1.0-plugins-base \
|
||||||
|
gstreamer1.0-plugins-good \
|
||||||
|
gstreamer1.0-plugins-bad \
|
||||||
|
libgstreamer-plugins-base1.0-dev \
|
||||||
|
libgstreamer-plugins-good1.0-dev \
|
||||||
|
libgstreamer-plugins-bad1.0-dev
|
||||||
|
|
||||||
|
2) Download and extract the package "gst-nvcompositor_src.tbz2" as follows:
|
||||||
|
|
||||||
|
tar -I lbzip2 -xvf gst-nvcompositor_src.tbz2
|
||||||
|
|
||||||
|
3) Run the following commands to build and install "libgstnvcompositor.so":
|
||||||
|
cd "gst-nvcompositor"
|
||||||
|
make
|
||||||
|
make install
|
||||||
|
or
|
||||||
|
DEST_DIR=<dir> make install
|
||||||
|
|
||||||
|
Note: "make install" will copy library "libgstnvcompositor.so"
|
||||||
|
into "/usr/lib/aarch64-linux-gnu/gstreamer-1.0" directory.
