from vilib import Vilib
def main():
Vilib.camera_start()
Vilib.display()
Vilib.rec_video_set["path"] = "/home/pi/video/test/"
vname = "vtest"
Vilib.rec_video_run(vname)
print('start rec ...')
while True:
if input() == 'q':
Vilib.rec_video_start()
print('continue')
if input() == 'w':
Vilib.rec_video_pause()
print('pause')
if input() == 'e':
Vilib.rec_video_stop()
print('stop')
print("The video saved as",Vilib.rec_video_set["path"],vname)
if __name__ == "__main__":
