Single DEI output

Hi

 

DM8168 EVM using ezsdk 5.02.01.59

I want to Use the DEI but do not want to display, I only want to send  data to Encoder. Is this possible??

Back ground:

I would like to convert a stream of HDMI DATA(HDMI camera sreaming into FPGA and into bufffer which is consumed by the DEI)  and encode it to a H.264 stream.

As a test to just get the DEI working with the Encoder. I have setup 2 components  OMX.TI.VPSSM3.VFPC.DEIHDUALOUT  and  OMX.TI.DUCATI.VIDENC.  (I setup  buffers which I populate with a colour bar and pass it to the DEI whcih outputs to the ENC. My  set up with call backs works because the Parameters are set when I call OMX_GetHandle. First I setup the DEI Handle This returns OK  Enabling the Output ports first which only works if I enable OMX_VFPC_OUTPUT_PORT_START_INDEX this works fine  (I presume this is port 16)

( next ) if I enable OMX_VFPC_OUTPUT_PORT_START_INDEX + 1 my program stops at the SempPend and freezes.

I then Enable Input port OMX_VFPC_INPUT_PORT_START_INDEX  = 0 this works fine if I ommit the last line.

I then setup the encoder input and output port (fine)

When i Allocate buffers the DEI  allocates buffers for the DEI Output and Input for that  component and then freezes at SempPend

So my questions are .

Question 1

Can I set the DEI to use a single output port or do I have to configure 2 output ports ?

Question 2

Why does the code stop when I try enable the second output port (If I leave this out and only enable the input and output it carrys on)?

Question 3

Why does my code stop at SempPend when I set up the ALLOCATE buffer comand on the input and output buffers (I alocate all input buffers and then all output buffers and then pend on Semaphore)?

Question 4

Do I have to setup the DEI number of inputs and ou puts and start index's using the "OMX_IndexParamVideoInit" command ?

Question 5

Can I fill a buffer with grey and give it to the DEI like the VPCC would?

 

Thanks

Robin
