Types

type Params

type Params struct {
	codec.BaseParams

	// Faster preset has lower CPU usage but lower quality
	Preset Preset
}

Params stores libx264 specific encoding parameters.

func NewParams

func NewParams() (Params, error)

NewParams returns default x264 codec specific parameters.

func (*Params) BuildVideoEncoder

func (p *Params) BuildVideoEncoder(r video.Reader, property prop.Media) (codec.ReadCloser, error)

BuildVideoEncoder builds x264 encoder with given params

func (*Params) RTPCodec

func (p *Params) RTPCodec() *codec.RTPCodec

RTPCodec represents the codec metadata

type Preset

type Preset int

Preset represents a set of default configurations from libx264
