Carl, Thank you for kindly responding. Yes, that's correct, that's what I am referring to. I have output the MPEG-7 video signatures for a list of videos (a video database). I then calculate the MPEG-7 video signature for a new video that I am considering adding to that database, so that I can compare the new video to the videos in the database via the signature only. (I imagine that using the MPEG-7 video signatures should be able to reduce the amount of time taken for this operation.)
I am trying to do something like this, but I think it may not be supported by ffmpeg.exe, but I am trying to be absolutely sure. Commandline> ffmpeg -i [1st signature file] -i [2nd signature file] -filter_complex signature=detectmode=full:nb_inputs=2 -f null - Any advice would be greatly appreciated. Thank you.
