Why does VideoCapture in opencv stop taking image from buffer even though video hasn't finished yet?

Question

OpenCV

I have a video file recorded from a gopro 9 camera. When I open it with cv2.VideoCapture, the images are captured for the first second, after which cv2.read() returns False, even though the video itself is 20 seconds long. I think it's the gopro, since any other video file that was not recorded with the gopro reads fine. I recorded video on gopro with different codecs (hevc / h.265, avc / h.264), with different resolutions and frame rates, anyway, after the first second, the video stream is interrupted. I tried to convert the video using the handBrake software, it all worked. Why can't I capture all frames from video recorded with gopro 9?
