| frame_analyzer.cc |
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. The video files should be I420 .y4m or .yuv videos.
If both files are .y4m, it's not needed to specify width/height. 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> --width=<frame_width> --height=<frame_height>

Prints the different metrics mainly:
1) Identical frame number, PSNR and SSIM values.
2) Length of continuous frozen frames.
3) Max length of continuous freezed frames.
4) No of unique frames found.
5) Total different identical frames found.
Sample output:
