Video stream became 'broken' randomly

See original GitHub issue

Streaming can work fine for 10 seconds or 10 minutes, but then suddenly it becomes like that:

Eventually it can fix itself, but sometime it does not. I have tried to stream from android device and browser and got same behavior. Any idea what can be wrong?

Frame processing looks like that:

async def recv(self):
        frame = await self.track.recv()

        if (self.transform == "nothing"):
            return frame

        try:
            networkWidth = self.detectionService.width
            networkHeight = self.detectionService.height
            
            widthScale = frame.width / networkWidth
            heightScale = frame.height / networkHeight

            frame_rgb = cv2.cvtColor(frame.to_ndarray(format="bgr24"), cv2.COLOR_BGR2RGB)
            frame_resized = cv2.resize(frame_rgb, (networkWidth, networkHeight), interpolation=cv2.INTER_LINEAR)

            darknet.copy_image_from_bytes(self.darknet_image, frame_resized.tobytes())
            self.lastDetection = self.detectionService.detect(self.darknet_image)
            self.detections.put(self.lastDetection)

            image = cvDrawBoxes(self.lastDetection, frame_rgb, widthScale, heightScale)
            new_frame = VideoFrame.from_ndarray(image, format="rgb24")
            new_frame.pts = frame.pts
            new_frame.time_base = frame.time_base

            return new_frame
        except:
            info = sys.exc_info()
            return frame;
