[HOW-TO] make this rtsp stream stable?

Start with camera.py, especially FfmpegOutput, the assigned error_callback, and start_encoder; main.py shows the continuous-running entry point. Reproduce the stream interruption and inspect the complete broken-pipe exception and callback output to determine whether the failure is reported by ffmpeg or Picamera2. Done means the failure source is identified and the stream's stability issue is addressed.

i have a example to push rtsp stream to my server
raspberrypi 4b
picamera2 0.3.18
python 3.11.2
camera.py

from picamera2 import Picamera2
from picamera2.encoders import H264Encoder
from picamera2.outputs import FfmpegOutput
from tool.log.log_uru import Logger


class Camera(object):
    def __init__(self, sn):
        self.rtsp = None
        self.lug = Logger().get_logger
        self.picam2 = Picamera2()
        # Picamera2.set_logging(Picamera2.DEBUG)
        # rtsp推流的编码
        self.encoder = None
        resolution = (1280, 720)
        self.picam2.configure(self.picam2.create_video_configuration(main={"size": resolution}))
        self.picam2.start()
        self.lug.info("Camera initialized")
        self.start_rtsp()

    def error_callback(self, e):
        """
        picamera2异常断开的回调函数
        """
        self.lug.error("Camera Error {}", e)
        # 重连
        # self.picam2.stop_encoder(self.encoder)
        # self.start_rtsp()
        # self.lug.warning("reconnecting...")

    def start_rtsp(self):
        # self.encoder = H264Encoder(bitrate=1000000)
        self.encoder = H264Encoder(bitrate=1000000, repeat=True, iperiod=15, framerate=15)
        self.rtsp = FfmpegOutput("-f rtsp rtsp://myserverip/live/test")
        self.rtsp.error_callback = self.error_callback
        self.encoder.output = self.rtsp
        self.picam2.start_encoder(self.encoder)

    def stop(self):
        """
        停止camera
        :return:
        """
        self.picam2.stop()

i run this camera.
main.py

if __name__ == '__main__':
   Camera("camera")
   while True:
     pass

However, if he pushes the RTSP stream for a maximum of 10 minutes, a broken pipe exception will appear。i want to know this is the ffmpeg's error or picamera2's error;
