VideoCapture Silence Warning - [h264 @ 0x559351d7b040] mmco: unref short failure

I’m using VideoCapture to load a video’s frames in batches. Eventually, my terminal starts spamming me with the following error, despite the program will running:
[h264 @ 0x559351d7b040] mmco: unref short failure
[h264 @ 0x559351d7b040] mmco: unref short failure
[h264 @ 0x559351d7b040] mmco: unref short failure
[h264 @ 0x559351d7b040] mmco: unref short failure
...

What’s causing this?
Is there any way to stop all warnings messages?

Sample Code:

vid = cv2.VideoCapture(vid_path)

    # Prepare `num_processors` batches of images
    for frame_num in range(start_frame, start_frame + batch_size):
                         
        vid.set(cv2.CAP_PROP_POS_FRAMES, frame_num)
        ret, frame = vid.read()
        if ret:
            frame = Image.fromarray(frame)
            frame = frame_transforms(frame)
            self.batch.append(frame)
