Describe the bug
对不起 我英文不太好
(I'm sorry, my English is not very good )
我从第三方系统（比如海康威视的isc平台）获取到了一个有有效期的rtsp地址
(I dynamically obtained a valid RTSP address from a third-party system 【such as hikvision iSecure Center 】)
这个地址只有5分钟有效期
(This address is only valid for 5 minutes)

按照这个系统的技术人员说明
(According to the technical personnel's instructions for this system)
只要开始使用这个地址播放视频了
(Just start using this address to play videos)
正在播放的视频是不会断开的
(The video being played will not be disconnected)

我使用vlc测试，持续测试了1小时视频还是很稳定
(I tested using VLC and the video remained stable even after 1 hour of continuous testing)

但是使用 webrtc-streamer ，播放5分钟后视频就断了
(But using webrtc streamer, the video ends after 5 minutes of playback)

To Reproduce
Steps to reproduce the behavior:

1. get new rtsp
2. play
3. wait 5 min
4. See error
