Same Issue here,

turns out my libmpv was outdated, so i had to manually add the deb-multimedia repository and install libmpv1 even tho it was already installed. The Joy of working with debian.

check out my project for context

@qbe I have this issue on raspberry pi os, do you know how to update libmpv1 there?

[qbe]

check what version of libmpv1 your distro has in which repository, add that repository, manually install libmpv1 to update libmpv1, and thats probably it

[BurlyLlama28]

@qbe I have libmpv1 version 0.32.0-3. What version of libmpv1 worked for you?

[qbe]

can't check right now, get a current version

[BurlyLlama28]

It seems kinda a problem, because 0.32.0 is the latest version for raspberry pi os

[BurlyLlama28]

Like really I don't know what to do :(

[qbe]

have you checked deb-multimedia ?

[qbe]

or check any other repository than the default raspbian one

[BurlyLlama28]

@qbe I somehow updated MPV by the Debian package, have this version right now

But still have the same issue

[qbe]

i cannot help you any further then

[BurlyLlama28]

@jaseg Maybe you can explain: why I have this issue?

[BurlyLlama28]

@jaseg I really need your help. It's important to me

Hey there, The guess by @qbe that this may be due to a version mismatch is probably right.

Could it be that you updated your mpv package (that has the mpv binary) but did not update your libmpv package (that has libmpv.so)? If I remember correctly debian has these two in two separate packages that can be updated independently.

You can check the libmpv version your python script is loading by printing the return value of mpv.MPV().mpv_version, e.g. using:

python3 -c 'import mpv; print(mpv.MPV().mpv_version)'
