虚度光阴的代价，就只能是被时间裹挟着前进了吗？
还能有时间去做好准备吗？现在来说，有点不甘心啊。

使用com.gluonhq:gluonfx-maven-plugin插件生成exe文件报以下错误。
java.lang.UnsatisfiedLinkError: no awt in java.library.path
解决方案：从JAVA_HOME下复制awt.dll、java.dll、server/jvm.dll这三个文件到exe所在的文件夹。
但接下来一般会伴随着java.lang.NoSuchFieldError …，还是不去使用awt/swing相关的内容吧。

java时区转换 String -> Date -> Calendar -> Instant -> LocalDateTime，用起来感觉很麻烦。
String uploadDate = "2023-01-20T04:46:00+00:00";
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ssXXX");
Calendar calendar = Calendar.getInstance();
calendar.setTime(sdf.parse(uploadDate));
LocalDateTime localDateTime = LocalDateTime.ofInstant(calendar.toInstant(), ZoneId.of("Asia/Tokyo"));
System.out.println(localDateTime.getHour());

Windows版本分为单文件版和安装版。

提取字幕
ffmpeg -i in.mkv -an -vn -scodec copy -map 0:s:x out.ass
0:s:x的x为第几个字幕，数字从0开始。
输出的字幕格式需要根据视频内的来指定，有ass，srt，sup等等…
