Hero 10 webcam python script

[druckgott]

Hallo I´m working on a script and want to read the hero 10 webcam video, but I do not want to show it with vlc player like it´s implementet, I want to use cv2

But I can´t get it working. The connection works I connect to the camera the hero 10 shows that webcam is aktiv, but I do not get a stream.

I did the same over wifi, therfore I get the stream but it was to laggy

Can you help me?

I fixed your code a little bit, now it works... kinda, it has a memory leak.

camId = "{CF7CD38D-B0DE-4C2F-B190-7E3A21CA75AE}"
gpCam = GoProCamera.GoPro(ip_address=GoProCamera.GoPro.getWebcamIP(
    camId), camera=constants.gpcontrol, webcam_device=camId, api_type=constants.ApiServerType.OPENGOPRO)
sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
gpCam.startWebcam()
time.sleep(2)
q = queue.Queue()

def handler(s, f):
    p1.stop()
    p2.stop()
    p3.stop()
    quit()

signal(SIGINT, handler)

def Receive():
    print("start Receive on %s" % GoProCamera.GoPro.getWebcamIP(camId))
    cap = cv2.VideoCapture(
        "udp://%s:8554" % GoProCamera.GoPro.getWebcamIP(camId), cv2.CAP_FFMPEG)
    while True:
        ret, frame = cap.read()
        if not ret or frame is None:
            print('video is all read')
            break
        q.put(frame)

    cap.release()
    cv2.destroyAllWindows()

def Display():
    print("Start Displaying")
    while True:
        if q.empty() != True:
            frame = q.get()
            cv2.imshow("GoPro OpenCV", frame)
        if cv2.waitKey(1) & 0xFF == ord('q'):
            p3.stop()
            break
        if q.empty() != True:
            frame = q.get()
            # Save the picture
            cv2.imshow("GoPro OpenCV", frame)
            # cv2.imshow(save_name, frame)
            if cv2.waitKey(1) & 0xFF == ord('q'):
                break

if __name__ == '__main__':
    p1 = threading.Thread(target=Receive)
    p2 = threading.Thread(target=Display)
    p3 = threading.Thread(target=gpCam.KeepAlive)
    p1.start()
    p2.start()
    p3.start()

very nice, I did use it, hero 10 says aktive, but there is no windows apearing I get:

Waking up... Camera successfully connected! Connected to 172.22.141.51
start Receive on 172.22.141.51 Start Displaying video is all read

I added cap.isOpenend() and there its always going wrong

    cap = cv2.VideoCapture(
        "udp://%s:8554" % GoProCamera.GoPro.getWebcamIP(camId), cv2.CAP_FFMPEG)
    if not cap.isOpened():
        print('VideoCapture not opened')
        exit(-1)

Make sure you use the code as-is and only change the camId, with your equivalent network interface id.

[druckgott]

And where can I get this camId in windows?

[KonradIT]

Use ./examples/get_iface_name_win.py

[druckgott]

Ok I now get the ID but it´s not working changed it to: camId = "{40BAB5DA-3918-43C7-98CF-55B4D403C704}"

This is what I import:

import cv2
import socket
from goprocam import GoProCamera, constants
import queue
import threading
from signal import signal, SIGINT
import time

But I get an error now:

Waking up...
Camera successfully connected!
Connected to 172.22.141.51    
start Receive on 10.5.5.9
Start Displaying
Exception in thread Thread-3:

sometimes I also get this as result:

Waking up...
Camera successfully connected!
Connected to 172.22.141.51    
Start Displaying
start Receive on 172.22.141.51
video is all read

I also testet to get the video like this: .\vlc.exe -vvv --network-caching=300 --sout-x264-preset=ultrafast --sout-x264-tune=zerolatency --sout-x264-vbv-bufsize 0 --sout-transcode-threads 4 --no-audio udp://:172.22.141.51:8554

But I don´t get any video. If I take the Browser I can reach the camera by: http://172.22.141.51/gp/gpMediaList
