在同时推4路rtsp视频流时出现lost video packet和Segmentation fault (core dumped）

zzqldnz

背景：
尝试用ffmedia的demo.py同时拉取四个视频流并进行转发
问题一：视频流可以播放，但是出现很严重的lost video packet现象，导致播放卡顿问题二：
在程序运行后出现Segmentation fault (core dumped）导致崩溃。

请问该如何解决，感激不尽。

提供完整log和对demo修复及使用方法，方便分析和复现。  
从目前的现象看：lost video packet提示的ffmedia推的rtsp流在等待客户端来接收包过程中超时了，他自动丢弃了这个包。
