type CrfSearch ¶

type CrfSearch struct {
	// contains filtered or unexported fields
}

CrfSearch will perform an interpolation search over CRF values to find the closest match to the target VMAF

func NewCrfSearch(logger zerolog.Logger, source string, targetVMAF float64, crfInitial int, crfMin int, crfMax int, tolerance float64, transcodeConfig commands.TranscodeConfig) *CrfSearch

func (c *CrfSearch) Run(ctx context.Context) (selected int, vmaf float64, err error)

type OptimizedEncoded ¶

type OptimizedEncoded struct {
	// contains filtered or unexported fields
}

func NewOptimizedEncoded(logger zerolog.Logger, cfg commands.TranscodeConfig, source string, target string, targetVMAF float64, crfInitial int, crfMin int, crfMax int, tolerance float64) *OptimizedEncoded

func (e *OptimizedEncoded) Run(ctx context.Context) error

type VMAFScore ¶

type VMAFScore struct {
	// contains filtered or unexported fields
}

VMAFScore will encode a sample of the source video with a given trancode configuration and return the VMAF score

func NewVMAFScore(logger zerolog.Logger, cfg commands.TranscodeConfig, referencePath string) *VMAFScore

func (v *VMAFScore) Run(ctx context.Context) (score float64, averageBitrateKBPS int, streamSizeKB int, err error)
