Can SGDMA connect VIP megacore function directly,such as clocked_video_input? 

 

In VIP user guide,it says that the VIP megacore function transfers video stream using Avalon-ST video protocal. 

 

There is Packet type identifier in the stream which is not needed in the Video Processing. 

 

If I connect like below: 

 

Clocked_Video_Input----(Avalon-ST)------>SGDMA------(Avalon-MM)----> PCIe 

 

Then the PCIe will get video data WITHOUT Packet type identifier? 

Or the Identifier STILL is in the video stream? 

 

Thanks for your answer.

In Avalon-ST video standard,there is control packet sent before video packet. 

If I use SGDMA to connect to Avalon-ST video source,such as Clocked Video Input or Color Sequence Plane,Then can SGDMA just output video packet,without Control Packet?
