Screen capturing with vlc and python

Here is simple code:

i = vlc.Instance()
player = vlc.libvlc_media_player_new(i)
m = i.media_new("screen://", ":screen-fps=24", ":sout=#transcode{vcodec=h264,vb=0,scale=0,acodec=mp4a,ab=128,channels=2,samplerate=44100}:file{dst=screencapture.mp4}", ":sout-keep")
player.set_media(m)
player.play()
time.sleep(10)
player.stop()
i.release()
