How can I convert from Buffer_Handle to IVIDEO1_BufDescIn

There is a finished project which is using DMAI framework.

Unfortunately, I don't know previous in detail even the hardware with FPGA. I got received only the source code.

But we need more codec features to setup the codec parameters like fixing Quantization Parameter or TWO Pass Encoding.

So I found the other intrerface called XDAIS.

My plan is to convert the captured data stored in Buffer_Handle structure to IVIDEO1_BufDescIn structure

to use H264VENC_encode and H264VENC_control function.

Please let me know any hints or the way to do that.

Thank you for reading.
