av.error.InvalidDataError: [Errno 1094995529] Invalid data found when processing input; last error log: [hevc] PPS id out of range: 6

When I'm trying to open an RTSP stream using PyAV, I encountered an issue. I attempted to open the RTSP stream with the following code:

import time

import av


class YDRtmpThread:
    def __init__(self):
        self.container = None
        self.reconnect()

    def start_capture_camera(self):
        while True:
            try:
                if self.fps is None:
                    time.sleep(1)
                    self.reconnect()
                    continue
                if self.frames is None:
                    self.frames = self.container.decode(video=0)
                frame = next(self.frames)
                img = frame.to_ndarray(format="bgr24")
            except Exception as e:
                print(e)
                self.fps = None

    def reconnect(self):
        try:
            self.frames = None
            self.fps = None
            rtmpUrl = ""
            self.close_container()
            options = {"rtsp_transport": "tcp"}
            self.container = av.open(rtmpUrl, options=options, timeout=10)
            self.container.non_block = True
            stream = self.container.streams.video[0]
            self.fps = stream.average_rate
            print(self.fps)
        except Exception as e:
            print(e)

    def close_container(self):
        if self.container:
            self.container.close()
            self.container = None


if __name__ == "__main__":
    yd = YDRtmpThread()
    yd.start_capture_camera()

However, I encountered an error: av.error.InvalidDataError: [Errno 1094995529] Invalid data found when processing input; last error log: [hevc] PPS id out of range: 6

This error, when it occurs, seems to lead to an increase in system memory when I attempt to reopen the same RTSP stream. There are indications of memory overflow, possibly resulting in a memory leak.

Can you reproduce this on 11.0.0?
