Example usage

The example executable will be located in your build directory, in the folder tests/examples with the name vectorextractor_example. Its usage is the following:

./vectorextractor_example <input video>

This example supports reading any container compatible with GStreamer with an H.264 stream inside or a raw H.264 file. It will output the extracted motion vectors to stdout in the following format:

mbWidth,mbHeight,srcX,srcY,dstX,dstY
