This should be fixed by #11996, could you validate?

[litoj]

when I try to compile it as described in readme, meson setup build gives me:

ERROR: Neither source directory 'build' nor build directory None contain a build file meson.build.```

I can confirm that #11996 fixes this for me under pipewire 0.3.75 w/ ao=pipewire

@JosefLitos

when I try to compile it as described in readme, meson setup build gives me:

Is your working directory the mpv source directory?

[litoj]

yes, but it seems to work for @q234rty so I would believe it works just as expected.

[t-8ch]

Can you give me a full transcript of your shell?

[litoj]

I am not sure what you mean by that. I am using fish.

[t-8ch]

You are still on the master branch of my repository.
Which is very old and does not contain the fix nor meson config.

For your convenience I pushed the new bugfix to my master branch.
Please delete your clone and redo the same steps.

[litoj]

oh, whoops, I was supposed to checkout.

[litoj]

yes, works just fine with your patch.
