It appears that mpv-legacy builds without any audio devices by default (even with all the variants I set); mpv --audio-device=help only shows "auto". Adding the +coreaudio variant fixed it for me. The cocoa deprecation warning is unrelated and is a holdover from prior versions of mpv. I am also on 10.12.

Thanks, I will add it after checking locally.

BTW, audio works for me, but colors are completely off. Anyway, let me see what can be done here.

UPD. I guess, coreaudio was not used due to a trivial typo: default_variants-append coreaudio should be `default_variants-append +coreaudio.

Does anyone know a specific version of mpv which worked correctly on any powerpc system? I could only get correct colors with SDL2 output, but that brings another complication. However SDL2 was broken on ppc until I have fixed it, and it was never used in mpv port anyway, even on x86. So I wonder how that worked and whether the issue is local to me.

[mrkapqa]

if remember correctly, every mpv version tried on powerpc had issue, sometimes garbled, sometime rasterized images, more so with nvidia than ati cards< maybe there could have passed other option to correct this behaviouur.

Sorry for a delay with this.

Is the issue resolved now?

[mrkapqa]

on computer it function now with suggested "sudo port install mpv-legacy +coreaudio" maybe can function also without additional suffix already again could be resolved.

Since it is a variant, it is correct to have +coreaudio on supported systems.

thank you very much! regarding port health:

this is unrelated, however on BigSur both Mpv and Mpv-legacy are reported as broken:

which is the proper one to install and should get fixed?
