Question about pyk4a.PyK4APlayback ()

[xin4431]

`def main():

k4a_playback = pyk4a.PyK4APlayback("C:/AppData/output.mkv")

k4a_playback.open()
cv2.namedWindow('Azure Kinect RGB', cv2.WINDOW_NORMAL)
while True:
    capture = k4a_playback.get_next_capture()

    if capture is not None:
        color_image = capture.color
        if color_image is not None:
            color_image_data = color_image.data
            color_image_data = np.array(color_image_data, copy=False)
            color_image_bgr = cv2.cvtColor(color_image_data, cv2.COLOR_BGRA2BGR)
            cv2.imshow('Azure Kinect RGB', color_image_bgr)

` That's my code。 The problem arises when, on the first frame, the color result in the capture object is None On the second frame, the color results in the capture object are shown below The final realistic image is shown below Why is that? Ask for Help

Is it possible that the depth sync is off? So first frame has depth but no color?

[shagren]

It's normal behavior. Very often first frame(s) missed color data. I think it can happens in middle of mkv too.
