Ffmpeg

Struct Ffmpeg 

Source
pub struct Ffmpeg { /* private fields */ }
Expand description

已解析的 FFmpeg 可执行文件句柄。

通过 Ffmpeg::resolvecheck_ffmpeg 获得,后续 extract_audioburn_subtitles 均复用同一实例。

Implementations§

Source§

impl Ffmpeg

Source

pub fn resolve(explicit: Option<&Path>) -> Result<Self>

解析 FFmpeg 路径。

  • explicitSome 时使用给定路径(须存在)
  • 否则在 PATH 中探测 ffmpeg / ffmpeg.exe
Source

pub fn path(&self) -> &Path

已解析的可执行文件路径。

Source

pub fn run(&self, args: &[&str]) -> Result<Output>

同步执行 FFmpeg 命令;非零退出码时返回 AppError::FfmpegFailed

args 为传给 FFmpeg 的参数列表(不含程序名本身)。

Source

pub fn run_in(&self, cwd: Option<&Path>, args: &[&str]) -> Result<Output>

在可选工作目录下执行 FFmpeg(用于 subtitles= 使用相对路径,规避 Windows 盘符转义问题)。
