Struct TimecodeFilter 

pub struct TimecodeFilter { /* private fields */ }

Timecode burn-in filter.

This filter overlays timecode and metadata information onto video frames.

Implementations

impl TimecodeFilter

pub fn new( id: NodeId, name: impl Into<String>, config: TimecodeConfig, font_data: Vec<u8>, ) -> GraphResult<Self>

Create a new timecode filter with a provided font.

Errors

Returns error if the font data is invalid.

pub fn from_font_file( id: NodeId, name: impl Into<String>, config: TimecodeConfig, font_path: &str, ) -> GraphResult<Self>

Load a font from a file path and create the filter.

Errors

Returns error if the font file cannot be read or is invalid.

pub fn config(&self) -> &TimecodeConfig

Get the current configuration.

pub fn set_config(&mut self, config: TimecodeConfig)

Update the configuration.

pub fn set_context(&mut self, context: FrameContext)

Update the frame context.
