No response

I carefully read all instruction and confirm that I did the following:

[X] I tested with the latest mpv version to validate that the issue is not already fixed.
[X] I provided all required information including system and mpv version.
[X] I produced the log file with the exact same set of files, parameters, and conditions used in "Reproduction Steps", with the addition of --log-file=output.txt.
[X] I produced the log file while the behaviors described in "Actual Behavior" were actively observed.
[X] I attached the full, untruncated log file.
[X] I attached the backtrace in the case of a crash.

You didn't build with vapoursynth.

[Very important]

No it's not.

How can I make

-Dvapoursynth=enabled

take effect?

CounterPillow commented 1 month ago

You need to specify it during build time as part of the meson configuration. If you are not compiling your own mpv, you'll have to learn how to do that.

The issue tracker isn't a tech support forum though. Please use Discussions for this.

meson_options

これは、中間子構成の一部としてビルド時に指定する必要があります。独自のmpvをコンパイルしていない場合は、その方法を学ぶ必要があります。

ただし、Issue Tracker はテクニカルサポートフォーラムではありません。これにはディスカッションを使用してください。

meson_options has option('vapoursynth', type: 'feature', value: 'auto', description: 'VapourSynth filter bridge').

meson setup --wipe build -Dvapoursynth=enabled

But it doesn't work.

Compiling your application that uses libmpv or somehow calls mpv otherwise with a "-Dvapoursynth=enabled" is not how this works. You need to compile mpv itself with that.

I wrote main.cpp in VS2022. Is this related?

CounterPillow commented 1 month ago

No.

I told you what the issue is.

The problem is that you do not understand as you do not actually know software development.

OP, assuming you are building mpv on Windows based on your log file, you first need to follow https://github.com/mpv-player/mpv/blob/master/DOCS/compile-windows.md. Then to enable VapourSynth during build, add this line before https://github.com/mpv-player/mpv/blob/d384a6b79303ef21b7330555e968a99d59a7c5b0/ci/build-win32.ps1#L214
