'read frames asynchronously from webcam using golang
Using Python, i've implemented a class that reads frames from webcam asynchrounously so i can increase the fps of my live stream everything was working quite well, i have been using the class WebcamVideoStream and FileVideoStream that are located in imutils.video. The code provided there is the next :
class WebcamVideoStream:
def __init__(self, src=0, name="WebcamVideoStream"):
# initialize the video camera stream and read the first frame
# from the stream
self.stream = cv2.VideoCapture(src)
(self.grabbed, self.frame) = self.stream.read()
# initialize the thread name
self.name = name
# initialize the variable used to indicate if the thread should
# be stopped
self.stopped = False
def start(self):
# start the thread to read frames from the video stream
t = Thread(target=self.update, name=self.name, args=())
t.daemon = True
t.start()
return self
def update(self):
# keep looping infinitely until the thread is stopped
while True:
# if the thread indicator variable is set, stop the thread
if self.stopped:
return
# otherwise, read the next frame from the stream
(self.grabbed, self.frame) = self.stream.read()
def read(self):
# return the frame most recently read
return self.frame
def stop(self):
# indicate that the thread should be stopped
self.stopped = True
i can start communication with the webcam using this line of code :
image = WebcamVideoStream("Camera_IP").start()
frame = image.read()
now am trying to do exactly the same thing but using gocv and golang, which means i dont want to use the function : gocv.OpenVideoCapture("url") and frame.Read(&img) directly but i want to make them in a separate thread, i made a lot of researches on the web to find a way to do it but no results, can anyone help me with that please ?
