Regarding Composite Display on DM8148 EVM

Hi ,

I am trying to capture 1080P Component video ,scale it down to SD resolution 720 x 480 and trying to display via composite port .

I am using OMX Capture-Encode application for this purpose . As there is no support for Composite video Display using OMX VFDC in EZSDK 5.02 ,i am trying to integrate the OMX Capture-Encode application and the saFBdevDisplay application for Composite Video display .

The way i approached is ,

As the DEI Component fills the Buffer at its Output Ports ,it calls the FillBufferDone() callback function which puts  the message FBD in the local pipe of the component .The IL_Client thread reads the msg FBD from the local pipe and calls IL_ClientProcessPipeCmdFBD() function .

I have tried to access the Processed Buffer at the output port of the DEI component and copied this buffer into the buffer_addr (this is the memory mapped buffer in the user space of saFbdevDisplay )

OMX_ERRORTYPE IL_ClientProcessPipeCmdFBD (IL_CLIENT_COMP_PRIVATE *thisComp,
                                          IL_CLIENT_PIPE_MSG *pipeMsg)
{
  OMX_ERRORTYPE err = OMX_ErrorNone;
  OMX_BUFFERHEADERTYPE *pBufferOut;
  IL_CLIENT_PIPE_MSG remotePipeMsg;
  IL_CLIENT_OUTPORT_PARAMS *outPortParamsPtr;
  int retVal = 0;

   pBufferOut = pipeMsg->pbufHeader;

  //add the Code for copying Buffer from DEI COMP output port  into Framebuffer .
  if(thisComp->startOutportIndex == OMX_VFPC_OUTPUT_PORT_START_INDEX)
   {
        printf("into the ProcessPipeCmdFBD function,copying  pBuffer to FB\r\n");
        buffer_addr = pBufferOut->pBuffer;
   }
 

I don't see any Display on the Composite channel ,Can anyone help me to integrate the OMX Capture-Encode app and saFbdevDisplay app for Composite Video Display .

Any help is appreciated .

Thanks,

Siva.
