通过使用指针public_stream,我们可以对该对象进行操作和访问。 在示例代码中,public_stream最初被初始化为nullptr,即空指针。这表示它当前不指向任何有效的对象。在解决错误"Expression: public_stream != nullptr"时,我们通过不同的方法来确保public_stream指针的有效性。 首先,我们通过使用new运算符为public_stream分配...
Expression: public_stream != nullptr For information on how your program can cause an assertion failure, see the Visual C++ documentation on asserts. (Press Retry to debug the application) 其实就是ffmpeg的空指针异常,这里是说数据流为空,原因有文件不存在、流为空等等 文章来源: blog.csdn.net,作者...
