hi, i'd like to report that the following command prints "error marking
filters as finished" at the end of the encoding and leaks memory until i
manage to quit ffmpeg, or even cause system crash and reboot sometimes
for version N-86175-g64ea4d1 (20170520-64ea4d1, 64 bit static), however
the command works fine for one of the previous versions i have, version

if you like, you may try to reproduce it quickly with the following -t 9
version of the original command i used for a much longer transcode (-t
57600, 16 hours).

i have also reproduced it without the sound (aevalsrc), so i think the
problem is with the filter loop.

if you really need the complete uncut console output for this case i may
reproduce the problem once more to supply it but for now, i really do
not want to risk another system crash :)

ffmpeg -f lavfi -i aevalsrc="sin((1000-t*0.0086805)*2*PI*t):s=48000:d=9"
-vf loop=size=1:loop=-1,hue=h=t*360/57600 -t 9 -pixel_format yuv420p
-c:v libvpx-vp9 -lossless 1 -c:a libvorbis -qscale:a 10 test1.webm
