# Packaging

## Memory interop library

The memory interop library (sub-component #1) is available via
APT/Debian installation `sudo apt install intel-dlstreamer-cpp` and
installed into folder `/opt/intel/dlstreamer/include/`, see
page
[Memory Interop and C++ abstract interfaces](./cpp_interfaces.md) for details.

## C++ elements and GStreamer elements

All C++ and GStreamer elements (sub-components #2 and #3) grouped by
library/framework they based on and compiled into separate .so shared
libraries and packaged into separate Debian packages with corresponding
dependencies on other packages.

Packages typically install two .so files named
`libgstdlstreamer_XYZ.so` and
`libdlstreamer_XYZ.so` where XYZ is name of framework the
elements based on. The first .so file contains all C++ elements, the
second is tiny .so file with GStreamer wrappers and registered as
GStreamer plug-in.

The following Debian packages are currently distributed in scope of
Deep Learning Streamer Architecture 2.0.

| Debian package | Dependencies |
|---|---|
| intel-dlstreamer-cpp | libc6-dev |
| intel-dlstreamer-dpcpp | intel-oneapi-compiler-dpcpp-cpp-runtime, level-zero, intel-level-zero-gpu |
| intel-dlstreamer-ffmpeg | libavcodec-dev, libavformat-dev, libavutil-dev, libswscale-dev |
| intel-dlstreamer-opencl | ocl-icd-libopencl1, intel-opencl-icd |
| intel-dlstreamer-opencv | libopencv-imgproc-dev |
| intel-dlstreamer-vaapi | intel-media-va-driver-non-free, libva-drm2, libva2 |
| intel-dlstreamer-openvino: |   |
