Functions

func NewEBU

func NewEBU(par *ffmpeg.Par) (*ebu, error)

Create a new video generator which generates the EBU Colour Bars

func NewSine

func NewSine(freq, volume float64, par *ffmpeg.Par) (*sine, error)

Create a new sine wave generator with one channel using float32 for samples. The frequency in Hz, volume in decibels and samplerate (ie, 44100) for the audio stream are passed as arguments.

func NewYUV420P

func NewYUV420P(par *ffmpeg.Par) (*yuv420p, error)

Create a new video generator which generates YUV420P frames of the specified size and framerate (in frames per second)

Types

type Generator

type Generator interface {
	io.Closer

	// Return the next generated frame
	Frame() *ffmpeg.Frame
}

Generator is an interface for generating frames of audio or video

type YCbCr10

type YCbCr10 struct {
	Y, Cb, Cr uint16
}

10-bit YCbCr values for the eight standard colors.

func (YCbCr10) Color

func (c YCbCr10) Color() color.YCbCr

Make 8-bit
