Topic: Unable to find mpv's PID [SOLVED]

Hi!

I have a rather peculiar problem here, I have svp setup w/ vapoursynth enabled mpv.
I have all the required applications settings and applications (lsof).

In the mpv config file ($HOME/.config/mpv/mpv.conf) I have:

input-ipc-server=/tmp/mpvsocket

but still I get the unable to find mpv's pid.

I don't see anything that's wrong, apart from it not working ofc.

Here is an strace snippet

poll([{fd=5, events=POLLIN}, {fd=6, events=POLLIN}, {fd=9, events=POLLIN}, {fd=20, events=POLLIN}, {fd=21, events=POLLIN}, {fd=23, events=POLLIN}], 6, 86) = 0 (Timeout)

write(2, "18:10:29.736 [E]: VideoPlayer: u"..., 5618:10:29.736 [E]: VideoPlayer: unable to find mpv's PID

I just edited my username to be <username> for anonymity.

At first, the connect fails, due to mpv not running (ECONNREFUSED), then when I start mpv
we can se that there is no error for the connect:

connect(39, {sa_family=AF_UNIX, sun_path="/tmp/mpvsocket"}, 110) = 0

then we can see that accessing lsof is fine:

access("/usr/lib/cw/lsof", X_OK)        = 0

and then at the bottom:

write(2, "18:10:29.736 [E]: VideoPlayer: u"..., 5618:10:29.736 [E]: VideoPlayer: unable to find mpv's PID

Can anybody tell me what's wrong?
Any help / pointers / insults very welcome!

Re: Unable to find mpv's PID [SOLVED]

Nevermind.... me is and idiot!

I should have figured it I cant use cw w/ svp, if I remove:

/usr/lib/cw/lsof

so I get:

> which lsof
/usr/bin/lsof

...and it works, hmm, might be a good idea to let (linux) users know that if they use cw they have to remove the lsof part in order for svp to work!

How do I mark this as solved?

According to the archlinux wiki (https://wiki.archlinux.org/index.php/Co … l_wrappers) it is a:

A non-intrusive real-time ANSI color wrapper for common unix-based commands.

What it does is color the output of common linux commands to make them more readable, pic attached.

13:46:20.679 [E]: VideoPlayer: unable to find mpv's PID

it seems SVP is trying to load youtube-dl , but i have uninstalled that; how can i instruct SVPTube to use yt-dlp instead, which is installed via pip3?
searched for it in SVP Utilities , all settings , but dont seem to find it there.
