关于mpp解码4路崩溃的问题

*平台： RK3399Pro

*环境：

系统内核：Linux debian10.toybrick 4.4.194-bRK3399Pro-Linux4-EMB-3532-V3.0-SHYM-g90d6dee

mpp版本：

toybrick@debian10:~$ dpkg -l | grep mpp

ii rockchip-mpp 1.4.0-5 arm64 Rockchip mpp Libraries

ii rockchip-mpp-dev 1.4.0-5 arm64 Development package for Rockchip mpp Libraries

toybrick@debian10:~$

解码分辨率：4路1920*1080视频流

复现步骤和问题：

1. gdb启动程序，解码4路rtsp流并显示。

2. 一段时间（约2小时）后程序崩溃，程序堆栈显示mpp错误。

堆栈日志：

mpp[30014]: mpp_log: MppDecoderDequeueFrame Get errror frame or discard frame

程序mpp调用代码片段如下：

m_pMppDecoder->ops->enqueue(lpModule->m_pMppDecoder, (uchar*)lpBuffer, dwBufferSize);
