Functions

Types

type FFMPEG

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

func (*FFMPEG) GetTotalFrames

func (l *FFMPEG) GetTotalFrames(filename string) (int, error)

func (*FFMPEG) ImageSize

func (l *FFMPEG) ImageSize(filename string) (image.Point, error)

func (*FFMPEG) Load

func (l *FFMPEG) Load(filename string, size image.Point) ([]image.Image, error)

Runs ffmpeg binary to ... if the file is video, get each frame of the video/gif if the file is image, get image with specified size. The frames are being loaded forehand and will get saved in the buffer. If the terminal size is altered, this whole process should happen again.
