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?
