You may still use packages from other PPAs or locally built libraries; you may need to rebuild nnstreamer subplugins (/ext/nnstreamer/*) accordingly. This is often due to the changes in interfaces of headers or the behaviors of APIs of libraries (e.g., openvino), which implies that they do not keep binary-wise backward-compatibility.

You need to keep using all related packages from nnstreamer/ppa ONLY IF you do not want to (potentially) rebuild anything.

Is it based on the fact that c is not primarily object-oriented and c ++ is? When I still had an amiga (around 1996 - 2000), I studied BASIC and I had it fixed that even though it is not object-oriented, it is possible to cheat and use objects :)

1. Not providing "object detection" example in C has NOTHING to do with C being non object-oriented. You can still write object detection example in C; you just need to slap in an object detection neural network model instead of an image classification model along with proper post processors of your choice. It has totally no relation.

2. There are C examples of object detection. Look at https://github.com/nnstreamer/nnstrreamer-example  / Tizen.native/ObjectDetection

  Besides, even in the C++ examples of /native directory, if you look closely, you can see that being object-oriented or not has no effect on object detection itself.

3. Although the characteristics of programming language has totally NOTHING to do with nerual network models (object detection), if you want object-oriented-like behavior, you may look at GLIB and GOBJECT. (not GLIBC)

Title : Re: [NNStreamer Technical Discuss] nnstreamer & openVINO

Thank you, so in other words shouldn't I use installation packages other than those from nnstreamer ppa (sudo add-apt-repository ppa: nnstreamer / ppa)?

I would like to ask more generally - I'm self-learning in programming and I work in c. Why in the examples is just "example_image_classification_tflite" in c and not "object detection"? Is it based on the fact that c is not primarily object-oriented and c ++ is? When I still had an amiga (around 1996 - 2000), I studied BASIC and I had it fixed that even though it is not object-oriented, it is possible to cheat and use objects :)
