when I run any code (for example streaming.py) olympe video renderer is just a black screen. It applies to both - simulated and a real drone. how can i fix it? currently i am trying to run this code
import argparse
import olympe
import os
import re
import sys
import time
from olympe.video.pdraw import Pdraw, PdrawState
from olympe.video.renderer import PdrawRenderer
from olympe.messages.onboard_tracker import start_tracking_engine
from olympe.video import HudType
DRONE_IP = os.environ.get("DRONE_IP", "192.168.42.1")
DRONE_RTSP_PORT = os.environ.get("DRONE_RTSP_PORT", "554")
def main(argv):
parser = argparse.ArgumentParser(description="Olympe Pdraw Example")
parser.add_argument(
"-u",
"--url",
default=f"rtsp://{DRONE_IP}:{DRONE_RTSP_PORT}/live",
help=(
"Media resource (rtsp:// or file://) URL.\n"
"See olympe.Pdraw.play documentation"
),
)
parser.add_argument("-m", "--media-name", default="DefaultVideo")
args = parser.parse_args(argv)
drone_ip = re.search(r"\d+\.\d+\.\d+\.\d+", args.url)
drone = olympe.Drone(drone_ip.group())
drone.connect()
drone(start_tracking_engine(box_proposals=True)).wait()
pdraw = Pdraw()
pdraw.play(url=args.url, media_name=args.media_name)
renderer = PdrawRenderer(pdraw=pdraw, hud_type=HudType.TRACKING)
assert pdraw.wait(PdrawState.Playing, timeout=5)
if args.url.endswith("/live"):
# Let's see the live video streaming for 10 seconds
time.sleep(10)
pdraw.close()
timeout = 5
else:
# When replaying a video, the pdraw stream will be closed automatically
# at the end of the video
# For this is example, this is the replayed video maximal duration:
timeout = 90
drone.disconnect()
assert pdraw.wait(PdrawState.Closed, timeout=timeout)
renderer.stop()
pdraw.destroy()
def test_pdraw():
main([])
if __name__ == "__main__":
main(sys.argv[1:])
Thats what i get:
