Video Player using OpenCV

This is an old code that I created sometime in 2010. While working on video shot detection, I needed a tool to perform frame-by-frame visual analysis. However, I wasn't aware of any that existed at that time and created one with Matlab. To sharpen my skills with C and OpenCV, I re-created the same, taking lessons from the best available book on these topics.

The control panel, buttons, text fields, slider, video screen, etc. which are all sub-regions of a big image, are implemented in C using the OpenCV library. The comments included in the code were useful to automatically generate this page using Doxygen

• Tested with:

  • Ubuntu 16.04.7 LTS (GNU/Linux 4.15.0-142-generic x86_64)
  • OpenCV 2.4.3

• How to compile?

  • The code can be compiled as follows:

  g++ video_player.c -o video_player `pkg-config --cflags --libs opencv`

  • To play a video pass the path of the video as the argument

  ./video_player some_video.avi
  

  • I compiled OpenCV-2.4.13 from source using the command

  unzip opencv-2.4.13.zip
  cd opencv-2.4.13
  mkdir build && cd build
  cmake -DWITH_CUDA=OFF ..
  make
  make install
