pip install cx-studio

要求 Python >= 3.12, < 3.15。

模块

core — 核心值对象

  • CxTime:SMPTE 时码解析与计算,支持 23.976 / 24 / 25 / 29.97 / 30 / 50 / 59.94 / 60 fps 等常见帧率。
  • FileSize:文件大小的类型化表示,支持 binary(KiB/MiB/GiB)与 international(KB/MB/GB)两种标准,提供 pretty_string() 人类可读输出。
  • TimeRange:时间区间运算,支持重叠检测、包含判断、时点与区间的关系判定。
  • Timebase:帧率抽象(fps + drop_frame),提供 from_fps() 工厂从帧率构造。

ffmpeg — FFmpeg 封装

  • FFmpegCodingInfo:编码信息值对象,包含编码器、时长、分辨率、比特率等字段。
  • FFmpegFilePathPreprocessor:路径预处理,处理引号兼容性与 Windows 路径适配。

filesystem — 文件系统工具

  • PathExpander:路径展开,支持通配符、环境变量和用户目录(~)。
  • CmdFinder:可执行文件查找,遍历 PATH 并检测有效后缀。
  • SuffixFinder:文件后缀匹配。
  • PathValidator / SuffixValidator / EmptyDirValidator / ExecutableValidator:路径验证链组件,支持组合与短路。
  • EncodingDetector:基于 chardet 的文本编码探测。

iotools — IO 工具

跨平台的子进程创建(Windows 下自动配置 CREATE_NEW_PROCESS_GROUP 以支持信号发送)、流式读写、字节流记录与重定向。

text — 文本工具

  • TagReplacer:模板标签替换系统,支持从对象属性、路径信息、环境变量等来源动态渲染文本。
  • auto_quote / auto_unquote:智能引号添加与去除。
  • random_string:随机字符串生成。
  • auto_list_text / auto_unwrap:文本按分隔符拆分与去换行。

number — 数值工具

  • NumberRange:带边界的数值范围对象,支持跨区间映射、百分比转换与 clamp 裁剪。
  • quick_clamp / quick_remap:便捷数值函数,功能类似 AE 表达式中的 clamp 与 remap。

system — 系统抽象

  • SystemType:平台枚举,区分 Windows / macOS / Linux / WSL / iOS / Android / FreeBSD。
  • is_user_admin:跨平台管理员权限检测。
  • opener:跨平台文件或 URL 打开(xdg-open / open / start)。
  • cross_runner:跨平台命令执行封装。

collectiontools — 集合工具

  • flatten_list:递归展平任意深度的嵌套可迭代对象。
  • iter_with_separator:在迭代元素间插入分隔符,适用于构建连接清单。
  • split_to_two:按谓词将序列拆分为两组。

i18n — 国际化

基于 gettext 的翻译基础设施,提供 _() 和 _ng()(复数)函数。简体中文为源语言。
