3) Analysis result textfile
The result of the whole analysis process is a simple plain-text file. This textfile contains the following information:
- Frame index in which an issue has been detected.
- A numeric value, representing the number of pixels deviating from the expected color.
- In case of timing issues, re-synchronization of the analyzer to the video stream is also logged, including the frame number in case of a successful re-sync.Thus the area between detected issue and re-synchronization, which could not been analyzed gets documented.
- For auditability purposes, the tolerance setting ("Fuzz factor"), as well as the video filename is logged, too.
