Struct EncoderConfig 

#[non_exhaustive]
pub struct EncoderConfig {
    pub video_codec: VideoCodec,
    pub audio_codec: AudioCodec,
    pub bitrate_mode: BitrateMode,
    pub resolution: Option<(u32, u32)>,
    pub framerate: Option<f64>,
    pub hardware: Option<HwAccel>,
}

Codec and quality configuration for the pipeline output.

Passed to PipelineBuilder::output alongside the output path.

Construct via EncoderConfig::builder.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

video_codec: VideoCodec

Video codec to use for the output stream.

audio_codec: AudioCodec

Audio codec to use for the output stream.

bitrate_mode: BitrateMode

Bitrate control mode (CBR, VBR, or CRF).

resolution: Option<(u32, u32)>

Output resolution as (width, height) in pixels.

Resolution precedence in Pipeline::run:

1. This field when Some — explicit value always wins.
2. The output dimensions of a scale filter, inferred automatically.
3. The source video’s native resolution.

When a scale filter is used via PipelineBuilder::filter you typically do not need to set this field; the pipeline infers the encoder dimensions from the filter. Set it explicitly only to override the filter’s output size or to resize without a filter.

framerate: Option<f64>

Output frame rate in frames per second.

None preserves the source frame rate.

hardware: Option<HwAccel>

Hardware acceleration device to use during encoding.

None uses software (CPU) encoding.

Implementations

impl EncoderConfig

pub fn builder() -> EncoderConfigBuilder

Returns an EncoderConfigBuilder with sensible defaults: H.264 video, AAC audio, CRF 23, no resolution/framerate override, software encoding.
