Error code -1074118645

I am trying to transmit video over USRP from webcam but I am getting "Error code -1074118645"  I even tried to reduce the I/Q rate but it does not work at all.

The error message which i am getting is given below:

Error code -1074118645 niUSRP Write Tx Data (CDB).vi<ERR>Underflow: the Tx buffer was emptied before new data was provided.  Consider reducing the IQ rate, increasing the Write rate, or increasing the number of samples per Write.

Can any body guide me how to fix this error. Thanks in advance.

Hello Joseph,

It seems like there is an active post regarding this topic. Since we try to avoid duplicated threads I would like to suggest posting your question on this forum.

A suggestion will be to describe a little bit more what you mean by “it does not work at all”, if you are using example code or if you have created your own VI please post it. Sometimes this issue could be solved increasing the IQ rate  or to benchmark the IQ Rate on the Continuous Async example.
