Struct FfmpegMp4Encoder 

pub struct FfmpegMp4Encoder { /* private fields */ }

Encoder that pipes frames to FFmpeg for MP4 encoding.

Supports native nearest-neighbor scaling via FFmpeg’s scale filter.

Implementations

impl FfmpegMp4Encoder

pub fn new( output_path: &Path, width: u32, height: u32, fps: f64, scale_to: Option<(u32, u32)>, ) -> Result<Self, VideoError>

Create a new FFmpeg MP4 encoder.

If scale_to is provided, FFmpeg will scale to that resolution using nearest-neighbor interpolation (sharp pixel edges).
