Types ¶

type LogLevel ¶ added in v0.10.0

type LogLevel int

LogLevel controls which x264 log messages are emitted.

const (
	// LogNone suppresses all log output from x264.
	LogNone LogLevel = iota
	// LogError shows only error messages.
	LogError
	// LogWarning shows warnings and errors.
	LogWarning
	// LogInfo shows info, warnings, and errors (x264 default).
	LogInfo
	// LogDebug shows all messages including debug output.
	LogDebug
)

type Params ¶

type Params struct {
	codec.BaseParams

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

	// LogLevel controls the verbosity of x264's internal logging.
	// Messages at this level and above severities will be emitted.
	// Defaults to LogInfo to match x264's default behavior.
	LogLevel LogLevel
}

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 ¶ added in v0.1.2

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

const (
	PresetUltrafast Preset = iota
	PresetSuperfast
	PresetVeryfast
	PresetFaster
	PresetFast
	PresetMedium
	PresetSlow
	PresetSlower
	PresetVeryslow
	PresetPlacebo
)
