Struct StreamingVideoEncoder 

pub struct StreamingVideoEncoder { /* private fields */ }

A streaming video encoder that handles scaling via FFmpeg.

This encoder is designed for use during emulation - frames are written immediately as they are generated, without buffering all frames in memory.

Scaling is handled natively by FFmpeg using nearest-neighbor interpolation, which is efficient and produces sharp pixel edges.

Implementations

impl StreamingVideoEncoder

pub fn with_fps_config( format: VideoFormat, output_path: &Path, src_width: u32, src_height: u32, resolution: &VideoResolution, fps_config: FpsConfig, ) -> Result<Self, VideoError>

Create a new streaming encoder with explicit FPS configuration.

This is the preferred constructor when using the new FPS multiplier system.

pub fn write_frame(&mut self, frame: &[RgbColor]) -> Result<(), VideoError>

Write a single frame.

pub fn finish(&mut self) -> Result<(), VideoError>

Finish encoding and finalize the output file.

pub fn frames_written(&self) -> u64

Get the number of frames written so far.

pub fn source_dimensions(&self) -> (u32, u32)

Get the source dimensions.

pub fn output_dimensions(&self) -> (u32, u32)

Get the output dimensions (after scaling).

pub fn is_scaling(&self) -> bool

Check if scaling is enabled.

pub fn fps_config(&self) -> &FpsConfig

Get the FPS configuration.

pub fn needs_mid_frame_capture(&self) -> bool

Check if mid-frame captures are needed.

pub fn captures_per_frame(&self) -> u32

Get the number of captures per PPU frame.
