Start dynamic decoding.
BOOL NET_DVR_MatrixStartDynamic_V41( LONG lUserID, DWORD dwDecChanNum, NET_DVR_PU_STREAM_CFG_V41 *lpDynamicInfo );
[IN] Value returned by NET_DVR_Login_V40.
[IN] Decoding channel No. or sub window No. (1-byte video wall No.+1-byte sub window No.+2-byte window No.)
[IN] Dynamic decoding parameters, see details in the structure NET_DVR_PU_STREAM_CFG_V41.
Return TRUE for success, and return FALSE for failure.
If FALSE is returned, you can call NET_DVR_GetLastError to get the error code.
After starting dynamic decoding by calling this API, the decoding will not stop until the NET_DVR_MatrixStopDynamic is called. If the network disconnected during decoding, the decoder will automatically reconnect to the encoding device until reconnected.
