Comment (by Cigaes):

 I read in the report:
 {{{
   Stream #0:0 -> #0:0 (utvideo (native) -> wrapped_avframe (native))
 bench: utime=69.007s
 bench: maxrss=80832kB

 real    0m9.651s
 user    1m9.011s
 sys     0m0.670s
 }}}
 and
 {{{
   Stream #0:0 -> #0:0 (libutvideo -> rawvideo)
 bench: utime=40.979s
 bench: maxrss=22828kB

 real    0m11.342s
 user    0m40.982s
 sys     0m2.014s
 }}}

 I find that rather convincing: the older ffmpeg with libutvideo decoding
 is 68% faster than the current one with native decoding. Is there
 something wrong?
