-/*
- * A tool running PSNR and SSIM analysis on two videos - a reference video and a
- * test video. The two videos should be I420 YUV videos.
- * The tool just runs PSNR and SSIM on the corresponding frames in the test and
- * the reference videos until either the first or the second video runs out of
- * frames. The result is written in a results text file in the format:
- * Frame: <frame_number>, PSNR: <psnr_value>, SSIM: <ssim_value>
- * Frame: <frame_number>, ........
- *
- * The max value for PSNR is 48.0 (between equal frames), as for SSIM it is 1.0.
- *
- * Usage:
- * psnr_ssim_analyzer --reference_file=<name_of_file> --test_file=<name_of_file>
- * --results_file=<name_of_file> --width=<width_of_frames>
- * --height=<height_of_frames>
