which shinchiro build compatible with mpv encoder?

[tatsumoto-ren]

I don't know. But it's easy to run it and test. Mpvacious should warn you if your installation of mpv is not compatible.

I'm also having an issue where sometimes (but not always) the snapshot process fails. I see this in the logs:

[subs2srs] Subprocess failed: unknown
[subs2srs] Couldn't create file: /Users/williamdavies/Library/Application Support/Anki2/User 1/collection.media/berserks01e21multi1080pwebx264aactsundereraws_00m06s757ms.avif

The file does exist, but it's empty.

When I press a in mpv to see the mpvacious options, I see

warning:
    your version of mpv does not support libaom-av1
    mpvacious won't be able to create snapshot files

I noticed that when I first installed mpv and mpvacious. I tried to debug things to make the warning go away. But I didn't succeed. But then I noticied that the snapshot files were being created successfully. So I forgot about it.

But now the snapshot is failing. I'm not sure when it fails/doesn't fail yet.

MacOS 14.7

MacOS 14.7

Install Arch Linux. mpv from the arch repos is guaranteed to work with libaom-av1.

Or try changing snapshot_format to webp or jpg if they're supported.

Thank you for such a quick reply! I've changed snapshot_format=avif to snapshot_format=webp. It worked just now once (will see if it causes problems later).

I know you love Linux and I totally understand why. But basically my only machine is a MacBook running MacOS so it's easiest for me if I can just run things on MacOS. I assume there must be a way to install Linux onto my MacBook and just run it as a Linux machine. I did also use VirtualBox to run a virtual Linux machine on my MacBook to do something like this. It worked but it wasn't super smooth (because of the VM, not criticizing Linux itself). Maybe I'll do a big complete switch to Linux at some point if it gets too difficult to run these things on MacOS :)

Thank you for all your great work!

[tatsumoto-ren]

Yes, the best option would be to install GNU without relying on virtualbox. It should be possible even on a macbook.

@william-davies I think I can help with your snapshot issue, and the libaom-av1 warning. It sounds like you might have had a similar problem to one I just resolved. The key is making sure that mpv is correctly linked to the Homebrew-installed FFmpeg, which provides libaom-av1 support.

Explanation:

The warning message "your version of mpv does not support libaom-av1" is misleading in this situation. The problem isn't that mpv itself lacks support, but rather that it might not be using the correct FFmpeg libraries. This can happen if:

• mpv was previously installed in a different way (e.g., manually, or an older version).
• There's a conflict with another FFmpeg installation on your system.
• The Homebrew linking process didn't complete correctly.
• mpv is linked to internal ffmpeg libraries.

Homebrew installs its packages (including mpv and FFmpeg) in isolated locations (within /opt/homebrew/Cellar on Apple Silicon, or /usr/local/Cellar on Intel). Then, it creates symlinks (symbolic links) in standard locations (like /opt/homebrew/bin and /opt/homebrew/lib) that point to the actual files. The brew link command manages these symlinks. If the links are broken or pointing to the wrong place, mpv won't find the correct FFmpeg libraries.

Solution:

The solution is to force Homebrew to re-establish the correct links for both mpv and ffmpeg:

brew link --overwrite mpv
brew link --overwrite ffmpeg
