Forum Post: RE: question about create DM8168 chains

Hi Badri,

          Thanks for your reply.

          I tried the DEI link in bypass mode, and I can not  get the stream in A8, through call the interface 

          IpcBitsInLink_getFullVideoBitStreamBufs()

          In my chains,  the dataformat of the stream , which from the capture link is progessive, and the function of the DEI link is De-interlace. 

          Is the DEI link can have  progressive stream as the input?  If it can, how should I to set the params of the DEI link? 

         Thanks!
