mjpeg
MJPEG video writer implementation in Go.
Examples
Let's see an example how to turn the JPEG files 1.jpg, 2.jpg, ..., 10.jpg into a movie file:
checkErr := func(err error) {
if err != nil {
panic(err)
}
}
// Video size: 200x100 pixels, FPS: 2
aw, err := mjpeg.New("test.avi", 200, 100, 2)
checkErr(err)
// Create a movie from images: 1.jpg, 2.jpg, ..., 10.jpg
for i := 1; i <= 10; i++ {
data, err := ioutil.ReadFile(fmt.Sprintf("%d.jpg", i))
checkErr(err)
checkErr(aw.AddFrame(data))
}
checkErr(aw.Close())
Example to add an image.Image as a frame to the video:
aw, err := mjpeg.New("test.avi", 200, 100, 2)
checkErr(err)
var img image.Image
// Acquire / initialize image, e.g.:
// img = image.NewRGBA(image.Rect(0, 0, 200, 100))
buf := &bytes.Buffer{}
checkErr(jpeg.Encode(buf, img, nil))
checkErr(aw.AddFrame(buf.Bytes()))
checkErr(aw.Close())
