对FFMpeg checkout 版本n4.2.5,实际得到master版本,导致后续OpenCV 4.5.4编译错误。使用“git checkout -b n4.2.hankf.01 remotes/origin/release/4.2”,解决问题,后续OpenCV编译成功。

}Checking for nullptr is pointless here: if the new call causes an error, the std::bad_alloc exception is thrown. If there's no need to throw an exception, one can use the std::nothrow construction — in this case the null pointer will be returned....
