-// There may be missing or duplicate frames. Also the frames start at a random
-// position in the original video. We should provide a statistics file along
-// with the test video. The stats file contains the connection between the
-// actual frames in the test file and their bar code number. There is one file
-// for the reference video and one for the test video. The stats file should
-// be in the form 'frame_xxxx yyyy', where xxxx is the consecutive
-// number of the frame in the test video, and yyyy is the barcode number.
-// The stats file could be produced by
-// tools/barcode_tools/barcode_decoder.py. This script decodes the barcodes
-// integrated in every video and generates the stats file. If three was some
-// problem with the decoding there would be 'Barcode error' instead of yyyy.
-// The stat files are used to compare the right frames with each other and
-// to calculate statistics.
