Struct MtmdVideoParams 

pub struct MtmdVideoParams { /* private fields */ }

Parameters controlling how a MtmdVideo stream is opened and sampled.

Obtain a default-initialised instance via MtmdVideoParams::default() (which mirrors mtmd_helper_video_init_params_default: ~4 fps, native ffmpeg/ffprobe from PATH, and a 5 s timestamp interval) and tweak it with the builder methods.

Implementations

impl MtmdVideoParams

pub fn fps_target(self, fps: f32) -> Self

Desired output frame rate. Values <= 0 mean “use the video’s native fps” (the default is ~4 fps).

pub fn timestamp_interval_ms(self, ms: i64) -> Self

Interval, in milliseconds, between inserted timestamp text chunks (e.g. "[10m50.5s]"). Values <= 0 disable timestamps (default 5000 ms).

pub fn ffmpeg_bin_dir(self, dir: Option<&str>) -> Result<Self>

Directory containing the ffmpeg/ffprobe binaries. Pass None to search PATH (the default).

Errors

Returns an error if dir contains an interior NUL byte.

Trait Implementations

impl Debug for MtmdVideoParams

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for MtmdVideoParams

fn default() -> Self

Returns the “default value” for a type.
