会出现一个巨大的无法关闭的框，整个播放器卡死

可以提供原视频吗。只是下载的url/磁力链接就可以

MCDFsteve commented 3 months ago

似乎是因为字幕本身是bitmap格式的，我目前的代码只考虑了srt ass/ssa vtt格式字幕的加载

VCB studio的轻音少女 S02E21; 我简单改了一下，现在这个位图字幕好了但是ASS乱码

MCDFsteve commented 3 months ago

ass也是通过javascript模仿的libass的加载，一些ass格式确实可能会导致乱码，尝试使用第三方工具将ass字幕烧录进视频作为硬字幕？

MCDFsteve commented 3 months ago

或者使用chatgpt等ai将ass字幕进行整理后手动装载？

yuygfgg commented 3 months ago

所有ass字幕里面的非ascii字符显示问号。然后你的意见是用户自己解决这些问题？

MCDFsteve commented 3 months ago

你将视频发给我试试？我看看修复方法

yuygfgg commented 3 months ago

怎么发给你？GitHub限制10MB

MCDFsteve commented 3 months ago

主流的网盘服务（或者个人网盘）都可以，直接提供给我你下载的来源链接也是足够的

MCDFsteve commented 3 months ago

如果都没有的话，可以在 https://dfsteve.top/wp-content/kod/ 内上传文件，这是我的私人网盘

我需要一些时间（或许是一天以上）来下载文件（顺便一提这也是我想想要的东西，轻音少女的收藏级资源）。在这之前你可以尝试使用 https://www.github.com/mcdfsteve/fnipaplay 来播放这些视频，这是我另一个播放器项目，虽然还在初期阶段，但是其内部是完整支持各种字幕格式的libass，应该可以正常渲染这些字幕。弹幕也是一样有的

OK感谢。我自己也再调调看

MCDFsteve commented 3 months ago

好的，等我下载下来视频以后会查看关于bitmap字幕的装载方法。这个issue在问题解决之前会保持开启

yuygfgg commented 3 months ago

可以考虑换用libass-wasm

MCDFsteve commented 3 months ago

后面看看

yuygfgg commented 3 months ago

https://github.com/yuygfgg/NipaPlay 我弄了一个简单的patch。然后ass到问题应该是我自己装了坏掉的字体一类的导致的，可以不用管

MCDFsteve commented 3 months ago

等我视频下载完毕以后亲自验证一下是否得到改善

MCDFsteve commented 2 weeks ago

可以考虑换用libass-wasm

1.6.4版本已将字幕加载器更换为了libass（连带着srt字幕一起，现在srt字幕的显示效果跟ass一样好了）
