/*
|
||
|
|
* 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, a stats file should be provided. The stats file
|
||
|
|
* is a text file assumed to be in the format:
|
||
|
|
* frame_xxxx yyyy
|
||
|
|
* where xxxx is the frame number in the test video and yyyy is the
|
||
|
|
* corresponding frame number in the original video.
|
||
|
|
* 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=<name_of_file> --stats_file=<name_of_file> --width=<frame_width>
|
||
|
|
* --height=<frame_height>
