What actually happened to quvi? Is it really still active? (https://github.com/legatvs?tab=repositories). No more commit since last year.
Same question for clive/cclive...
By the way, FFmpeg has support for the 0.4 branch of libquvi, so if you built it with --enable-libquvi you can ffmpeg -i http://youtube... (assuming libquvi and its scripts still work)
