Types

type Frame

type Frame struct {
	Data                  []byte
	Width, Height, Stride int
}

Frame represents decoded frame from H.264 stream Data field will contain bitmap data in the pixel format specified in the decoder

func (*Frame) ToRGB

func (f *Frame) ToRGB() *rgb.Image

ToRGBA converts the frame into image.RGBA The returned image share the same memory as the frame

type H264Decoder

type H264Decoder struct {
	// contains filtered or unexported fields
}

func New

func New(pxlFmt PixelFormat) (*H264Decoder, error)

New creates new H264Decoder It accepts expected pixel format for the output which

func (*H264Decoder) Close

func (h *H264Decoder) Close()

Close free ups memory used for decoder structures It needs to be called to prevent memory leaks

func (*H264Decoder) Decode

func (h *H264Decoder) Decode(data []byte) ([]*Frame, error)

Decode tries to parse the input data and return list of frames If input data doesn't contain any H.264 frames the list will be empty

type PixelFormat

type PixelFormat int
