* A command line tool running PSNR and SSIM on a reference video and a test
* video. The test video is a record of the reference video which can start at
* an arbitrary point. It is possible that there will be repeated frames or
* skipped frames as well. In order to have a way to compare corresponding
* frames from the two videos, two stats files should be provided. One for the
* reference video and one for the test video. The stats file
* is a text file assumed to be in the format:
* frame_xxxx yyyy where xxxx is the frame number in and yyyy is the
* corresponding barcode. The video files should be 1420 YUV videos.
* The tool prints the result to standard output in the Chromium perf format:
* RESULT <metric>:<label>= <values>
* The max value for PSNR is 48.0 (between equal frames), as for SSIM it is 1.0.
* Usage:
* frame_analyzer --label=<test_label> --reference_file=<name_of_file>
* --test_file_ref=<name_of_file> --stats_file_test=<name_of_file>
* --stats_file=<name_of_file> --width=<frame_width>
* --height=<frame_height>
