I think this could be a very interesting project, but maybe also very hard. I myself do not have the skills or knowledge to help in any way in that area. I think a few fingerprinting algorithms of the kind exist. Implementing them with ffmpeg's DSP infrastructure would probably be easier than designing one from scratch. OTOH, there is one use that I have in mind that may not be covered by existing algorithms: fingerprinting a short segment of audio to search for it efficiently and accurately in a larger footage without access to the original segment, and even if it was subjected to a different lossy codec or even small changes in pitch or speed. To be honest, I do not know if it is even possible, but it would be very useful. Regards, -- Nicolas George
