Call the AEGP_GetNewStreamValue() method to pass parameters but report an error

Greetings all,

I want to call the AEGP_GetNewStreamValue() to get value of the streamH, but the result always return A_Err_PARAMETER. Can anyone help me what is the problem?

The revelant code is as follows:

AEGP_LTimeMode time_mode = AEGP_LTimeMode_LayerTime;
A_Time timeT = {0,1};
AEGP_StreamValue2 stream_value;
ERR(suites.StreamSuite5()->AEGP_GetNewStreamValue(S_my_id, streamH, time_mode, &timeT, TRUE, &stream_value));

Kindly, all your help is appreciated!
