Very very much faster, I think you mean!  Thanks for the correction.   
I haven't ever made much use of the -ss flag in ffmpeg, so I made a  
wrong assumption after a quick test.

Interestingly, the faster way seems to always start one frame earlier  
than the slower way, which would seem to be a bug (someone used 1- 
based indexing for the frames instead of 0-based, I'll bet).
