Question

var u:uint = 1
var cam2 = Camera.getCamera(String(1))
    cam2.setMode(480,500, 25)
    cam2.setQuality(0,100)

vid2.attachCamera(cam2)
vid2.rotation = -90
vid2.y = 480

    if(u == 1) {

        u = 0
        cam2 = Camera.getCamera(String(u))
        vid2.attachCamera(cam2);
        vid2.rotation = 90

        u = 1
        cam2 = Camera.getCamera(String(u))
        vid2.attachCamera(cam2)
        vid2.rotation = -90
        vid2.y = 480

Answer 1

in app.xml...

change to

<renderMode>direct</renderMode>

I have found that when use render mode "auto" or "cpu", this issue happen. But when use "direct", it's OK.
