MPP1.4.0的问题，官方解码demo打印错误

我测试了官方提供的解码demo，会打印以下结果。测得是/usr/share/rockchip-mpp/example/legacy/mpp_decode。我在自己的项目中用了这个库，跑了几天代码是稳定运行的，功能也是正常的，但是log日志会一直增加，存储会满。盲猜版主会让我看新的MPP库，但是我没时间大量修改代码了。卖家问题老是让买家买单。

我现在担心花大把时间把解码改成其他版本，结果还是一样

解决办法：
1. 把错误信息重定向到/dev/null
2. 执行命令升级mpp库：
    sudo apt update
   sudo apt upgrade （如果只想升级mpp库，可以执行命令：sudo apt install rockchip-mpp-dev）

更新到1.4.0-5可以了，不会输出log了。昨天还是有问题的1.4.0-4。
