C++ code definition

Typedef struct stPlay

{

HWND wndPlay;// playback window handle

Whether bool bAudio;// plays audio or not. Now you can only play one audio stream.

PlayType type;// playback type

/ / only for net play.

TransmissionType eTranType;// data transfer type, 0m / m UDP, 1m / m TCP

Char url [260]; / / RTSP URL or local file path

Char szUser [64]; / / user name

Char szPassward [64]; / / password

Char szFileName [512]; / / for playback and download, download with full path such as D:\\ picuture.mpg

} stPlay

C # code definition

Public struct stPlay

{

Public IntPtr wndPlay;// playback window handle

Whether public bool bAudio;// plays audio or not. Now you can only play one audio stream.

Public PlayType type;// playback type

Public TransmissionType eTranType

[MarshalAs (UnmanagedType.ByValTStr, SizeConst = 260)]

Public string url; / / RTSP URL or local file path

[MarshalAs (UnmanagedType.ByValTStr, SizeConst = 64)]

Public string szUser; / / user name

[MarshalAs (UnmanagedType.ByValTStr, SizeConst = 64)]

Public string szPassward; / / password

[MarshalAs (UnmanagedType.ByValTStr, SizeConst = 512)]

Public string FileName

}

In order to be able to specify the length of a string, you must call [MarshalAs (UnmanagedType.ByValTStr, SizeConst = 512)]

Otherwise, by default, the length of the FileName may be only 32 bytes, causing the data transfer to fail
