Can't reproduce.

mpv 0.29.1?
anything unusual in mpv.conf?

Hi, is there any other info I can give you to help diagnose / reproduce this problem?  Maybe a test build with instrumentation / logging to indicate what args the SVSmoothFps filter is getting?

Yes, 0.29.1.

Here's my full mpv.conf:

hr-seek=yes
load-scripts=yes
#script=Blackbox
#script=excerpt

I moved my ~/.mpv/scripts folder aside to rule out any auto-loading scripts being the problem, but the problem persisted.

At least on my system, passing -p (pid) doesn't have this delay, so if you had the pid already (or some way to get it) you could add -p argument to get the file descriptor.  Not helpful if you're using lsof to get the pid in the first place... in which case maybe reach out to mpv developers (submit a PR?) to allow get-property to get pid (or even file descriptor if that's what you need from lsof) directly from mpv?

I'm using SVP 4 Mac 4.30.0.150 with mpv 0.29.1.  It works great, but it takes 10-15 seconds from when mpv starts up to when SVP begins interpolating videos.  This is just for the first item it plays -- if I play multiple items in a playlist, SVP works immediately when skipping to the next track.  Is this normal, and is there a way to reduce or eliminate this delay?

My mpv config is here:

ytdl-format=[protocol!=http_dash_segments]
slang=eng
no-osc
no-sub
sub-font-size=36
native-fs=no
keep-open=yes
keep-open-pause=no
input-ipc-server=/tmp/mpvsocket
hwdec-codecs=all
hwdec=auto-copy
opengl-early-flush=no
hr-seek-framedrop=no
no-resume-playback
hr-seek=yes

Thanks.
