使用自研板载，不接入相机，开启video0 1，开流后，vi-output占100% ，如果这时候关闭流会系统卡死。

在5.1.1和5.1.2上，也有同样问题，使用

的解决方案是可以解决的，但是在6.0上不生效。

并且使用6.2版本，不添加补丁也没有这个问题

希望提供6.0的解决方案

hello qqqqq1,

is it a must to stay-on JetPack 6.0/L4T 36.3?
we do not back-port the changes, usually.
please moving forward to the latest JP-6 public release version.
