@zhongfly @dyphire 现在已支持静态编译，也添加了libmpv的编译。可以作为shinchiro编译版的横向参考，算是另一种编译方案吧。原创是nyfair，我只是做了一些组件添加，尽量和shinchiro编译版的功能保持一致。 |

确实有，看漏了。虽然shinchiro也第一时间添加了libunibreak，但由于mpv尚未支持libass的ASS_Feature的相关api，所以实际上不基于修改版mpv编译的话还用不到也没有相关功能（ 有趣的是libass的ass_track_set_feature的api实际上是mpv开发者wm4添加的 |

其实没有那么复杂，mpv要引入WRAP_UNICODE的特性的话也主要是用来解决mpv-player/mpv#2203, libass/libass#360. 也就是OSD文本和字幕溢出的问题，不需要太复杂的解决方案，没必要完全实现完整的换行算法。ASS Feature目前其他两个特性一个括号双向匹配主要服务阿拉伯语字幕一个整体文本处理主要是bidi和\fay重塑，也是有待mpv添加ass_track_set_feature的api，不过我觉得等api进一步改进后libass开发者也会向mpv提交相应实现的pr，目前该api还存在一些不足。 |
Beta Was this translation helpful? Give feedback.
-
|
mpv引入WRAP_UNICODE特性后有明显感知和改善的是OSD文本显示。字幕反而很少感知到，因为常规字体大小下会溢出的不规范字幕还是较少的，只有人为加大字号才会感知到行为的变化。 |

我的在Archlinux Docker下交叉编译版本来咯: https://github.com/eko5624/mpv-winbuild 最大的优点是可以进行并行编译，所以全新编译下来速度比shinchiro的编译速度快很多。大家可以自由选mcf线程版本和posix线程版本。暂时只提供64位的编译。它们的区别主要是使用线程不同，也可能会带来性能的些许差异，具体可以看lhmouse大佬的讲解：msys2/MINGW-packages#13259 目前的小瑕疵是mcf静态编译版因为libaribcaption库的原因仍然需要依赖libmcfgthread-1.dll这个动态库文件，故不算是真正意义的静态编译版本。我暂时想到的方法是选择编译libaribb24进行平替，可以算真正意义上的静态版本了。这也就是我为什么把动态编译版设置为默认分支的原因啦~ 感谢这几位大佬的帮助：lhmouse, nyfair, shinchiro。在他们的帮助下，我才顺利构建了工具链。 |

@zhongfly 按照你的提示简化了一下在windows下编译的流程，如下： 这个流程有个问题就是：需要等待standalone-pkgs整个job里的所有包全部编译完成后，才能编译需要依赖standalone-pkgs里包的其它包，这无疑会降低整个编译速度。比如dav1d只依赖xxhash。我的要求是只要standalone-pkgs里的xxhash编译完成后就开始编译dav1d。dav1d里的 |
