For the following command line
time ./ffprobe -f lavfi \
"sine=440:r=8000:d=86400:samples_per_frame=2048,aresample=24000:filter_size=1:phase_shift=0" \
-show_packets >/dev/null
Before the patch:
real 0m3,916s
user 0m3,812s
sys 0m0,104s
After the patch:
real 0m3,597s
user 0m3,457s
sys 0m0,140s
So it actually speed things up.
Regards,
Marton
