1. Download two test videos:
```bash
wget https://github.com/ietf-wg-cellar/matroska-test-files/raw/master/test_files/test1.mkv
wget https://test-videos.co.uk/vids/jellyfish/mkv/360/Jellyfish_360_10s_5MB.mkv
```
2. I modified a OpenCV videoio sample to demonstrate the problem, here it is the patch: http://dpaste.com//C9MAT2K6W

Added scripts for creating an AAR package and a local Maven repository with OpenCV library #24456
Added scripts for creating an AAR package and a local Maven repository with OpenCV library.
The build_java_shared_aar.py script creates AAR with Java + C++ shared libraries.
The build_static_aar.py script creates AAR with static C++ libraries.
The scripts use an Android project template. The project is almost a default Android AAR library project with empty Java code and one empty C++ library. Only build.gradle.template and CMakeLists.txt.template files contain significant changes.
See README.md for more information.
