Title: Allow non-strict comparison of file metadata.

This seems to work for me to combine two files that are very close in framerate and videorate, but not identical. I'm not sure if it might be better if the comparison is made in terms of the percentage difference between the factors rather than by rounding to 1 decimal place. Someone with more knowledge on the matter can make that decision.
