Variables

var (
	// ErrTooLarge reports if more frames cannot be added,
	// else the video file would get corrupted.
	ErrTooLarge = errors.New("video file too large")
)

Types

type AviWriter

type AviWriter interface {
	// AddFrame adds a frame from a JPEG encoded data slice.
	AddFrame(jpegData []byte) error

	// Close finalizes and closes the avi file.
	Close() error
}

AviWriter is an *.avi video writer. The video codec is MJPEG.

func New

func New(aviFile string, width, height, fps int32) (awr AviWriter, err error)

New returns a new AviWriter. The Close() method of the AviWriter must be called to finalize the video file.

type Decoder

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

Decoder decode motion jpeg

func NewDecoder

func NewDecoder(r io.Reader, b string) *Decoder

NewDecoder return new instance of Decoder

func NewDecoderFromResponse

func NewDecoderFromResponse(res *http.Response) (*Decoder, error)

NewDecoderFromResponse return new instance of Decoder from http.Response

func NewDecoderFromURL

func NewDecoderFromURL(u string) (*Decoder, error)

NewDecoderFromURL return new instance of Decoder from response which specified URL

func (*Decoder) Decode

func (d *Decoder) Decode() (image.Image, error)
