A few questions about specifying a Video Engine 关于指定 Video Engine 的几个问题

[DOSforever]

由于 Sutitle Edit 无法自行下载 mpv lib ，所以我根据 URI 单独另行下载了 libmpv2-64.zip ，那么下载后应该把 libmpv2-64.zip 或解压后的 libmpv-2.dll 文件后应该放在 Subtitle Edit 的哪个目录中才能生效？
如果指定 VLC media player ，可以提供 portable 版的路径，但为什么对 MPC-HC 却没有提供 portable 版的路径选择呢？

Since Sutitle Edit can't download the mpv lib by itself, so I downloaded libmpv2-64.zip separately according to the URI, then which directory of Subtitle Edit should I put the libmpv2-64.zip or the unzipped libmpv-2.dll file in to make it effective?
If I specify VLC media player, it can provide the path of portable version, but why there is no path of portable version for MPC-HC?

libmpv files needs to go into the SE data folder - press Ctrl+alt+shift+d in the main SE window to open this folder

我用的是 SE405.zip portable version ，当我按 Ctrl+alt+shift+d 时打开的就是 SubtitleEdit.exe 文件所在的 SE405 主目录，我把 libmpv-2.dll 放在该目录中，启动 Subtitle Edit ，在 Video Player 选项中点选了 mpv ，此时 Download mpv lib 按钮仍可用，点 OK 退出 Settings ，打开一包含字幕流的视频文件，点播放按钮无任何反应。但是如果选择的是 VLC 则可以播放。

I am using the SE405.zip portable version. When I press Ctrl+alt+shift+d, it opens the main directory of the SubtitleEdit.exe file. I placed the libmpv-2.dll in that directory. I started Subtitle Edit, selected mpv in the Video Player option. At this point, the "Download mpv lib" button is still available. I clicked OK to exit Settings, opened a video file containing subtitle streams, and clicked the play button with no response. However, if VLC is selected, it can play.

It should be the correct folder.

What Os are you using and is it 64-bit?
You cannot select "mpv" via the radio button?

Yes, I'm using Windows 7 64-bit Home Edition, The SE405 is also a 64-bit version.
I can select "mpv" via the radio button same as your screenshots.
